• Lavina: hello all :)
• Pradeep: hey
• Geoff: mornin' :)
• Kirk: hey hey
• Lavina: how goes?
• Geoff: groggily
• Geoff: you?
• Lavina: pretty good
• Geoff: :)
• Lavina: Ecstatic to have my net back online at home
• Geoff: :D yay!
• Lavina: Are we waiting for anyone else?
• Pradeep: just came here after a long afternoon nap...it's evening here..
• Pradeep: hello every1..
• Lavina: hi Pradeep :)
• Tom: I suppose we can wait for a little while
• Kirk: not today -- next week we should do a better job of telling everyone where we have our meeting
• Kirk: I forgot that they don't know our Yahoo id's
• Kirk: ;)
• Lavina: eep
• Tom: ok
• Lavina: what if we send out an email now
• Pradeep: the new guys, eh?
• Lavina: they may be online waiting for a signal
• Kirk: sure, go for it
• Kirk: good idea
• Lavina: Ok :)
• Pradeep: I do see Jay online..though it says "idle"..
• Tom: ok shall we start?
• Lavina: sure
• Pradeep: go ahead..
• Tom: pradeep could you give us an update on the cubesat registration?
• Pradeep: I've sent an email to their id...they have yet to respond....that was done this Wednesday..
• Pradeep: also, it carried the names of everyone who have given their names till Wednesday..both from the wiki and the applications (team apps)..
• Tom: ok I suppose we'll have to await their reply then:)
• Jay: hi hi
• Tom: hi Jay
• Lavina: Quick aside. I'm going to invite PhilSEDS members to sit in the meeting :)
• Jay: i m sorry i m late
• Lavina: Is that okay?
• Tom: fine by me:)
• Matthew Ang entered the room.
• Pradeep: no probs..
• Lavina: This is Matthew Ang :)
• Lavina: Matthew, this is the core group of SEDSat-2. Pretty much the people who did the Mission Feasibility Study.
• Lavina: And hello, Jay :)
• Geoff: 'lo :)
• Jay: hello lav
• Pradeep: hello :)
• Matthew Ang: hey there :)
• Pradeep: we're a bit too much on the smilies...hey Matthew..nice to meet you..planning on joinin'?
• Matthew Ang: yup!
• Tom: any subsystem perference?
• Jay: guys i have exams tomorrow so i have to rush off...
• Tom: ok, good luck
• Tom: ok let's move on shall we
• Tom: Geoff you there?
• Matthew Ang: i'm not really sure...
• Pradeep: seems all quite around here..can we get on?
• Lavina: PhilSEDS will be applying to work on the Communication subsystem :)
• Geoff: yup
• Tom: do you have an update on the launch?
• Geoff: the whole of PhilSEDS or just you?
• Leah entered the room.
• Leah: hi everyone
• Tom: hi
• Leah: leah here from philippines
• Leah: hows everyone doing?
• Lavina: Sorry, this is Leah, the vice president of PhilSEDS
• Lavina: Leah, we've just discussed the registration of the SEDSat2 with CubeSat Calpoly
• Leah: i see.
• Geoff: welcome back leah :)
• Leah: thanks
• Lavina: Alrighty, I think that's it from PhilSEDS. Sorry for the interruption
• Geoff: :)
• Tom: geoff: the launch info...
• Tom: ok let's save that for a bit later then
• Gian Bernardo entered the room.
• Jay: jus a min guys.. i hav some requirements under my ownership in protoforge.. if u can lemme know to whom it beongs i would transfer them to you..
• Geoff: ?
• Geoff: oh
• Tom: what are the requirements
• Pradeep: Jay, Aaron has shifted some of the requirements to the team members so that the team gets to manage the requirements.
• Pradeep: he used to own them previously..
• Pradeep: Aaron I mean..
• Jay: ok alright..
• Geoff: whoa, protoforge changed appearance
• Geoff: heh
• Jay: sorry to leav u abruptly.. but i gotta leave now.. good luck with the meeting guys...
• Tom: ok
• Geoff: :S okay jay, see you :)
• Jay left the room.
• Tom: let's talk about the IAC 2k7 abstract for a while
• Tom: SEDSAT-2
• Tom: sorry
• Tom: SEDSAT-2_IAC_2007_Paper
• Geoff: np, I'm still waiting for thunderbird to load
• Tom: what do you need thunderbird for?
• Geoff: (I really should reschedule AVG's scans, grumble)
• Geoff: e-mail
• Geoff: :)
• Tom: ok
• Geoff: all my addresses in one central location
• Geoff: it's nice
• Geoff: :)
• Tom: let's all have a look at that abstract(courtesy of Juan)
• Tom: what do you guys think?
• Kirk: not bad -- might change the wording in the objective
• Tom: yeah I see there are a few typos too
• Kirk: instead of saying we will do all of these things, say that we will choose from submitted payload ideas (which will include those)
• Lavina: reading it now
• Kirk: Juan has registered with IAC to submit the abstract as well
• Pradeep: since we don't yet have a payload idea, it would be better to say that..
• Pradeep: ok..
• Tom: yep
• Tom: ok next Sunday will be the final deadline for this abstract
• Lavina: Hang on a sec?
• Tom: ok
• Lavina: Juan has registered? Do we all have to register?
• Kirk: maybe....
• Kirk: the response from the IAC committee is very slow
• Pradeep: I have been receiving mails from the IAC, courtesy of my last year's registration..I think.
• Tom: I was only "accompanying person" last year, so I don't get perks like that:)
• Lavina: so should I register even though we're all submitting one paper?
• Tom: although accompanying who exactly, I don't quite know:-)
• Kirk: I think so, Lavina, but I am not sure
• Pradeep: Kirk, we all registered while presenting that paper last year..I
• Kirk: I think that if your name is on the paper, you must be registered
• Pradeep: I mean you, me, Maryam and Adolfo..
• Lavina: we should double check those rules
• Pradeep: though only Adolfo was submitting and stuff.
• Kirk: yes, everyone must register then
• Kirk: www.iafastro.org
• Tom: where does one register then?
• Matthew Ang: hey i gotta go. nice meeting you guys
• Matthew Ang left the room.
• Kirk: on the left, there is a form that says "sign in / join us"
• Kirk: register an account there for an IAC paper
• Lavina: on it
• Kirk: then you have to wait "48 hours" (or more, because I am still waiting) to be approved
• Tom: authors it is then?
• Kirk: yes
• Pradeep: so, we have to re-register?
• Tom: new entry or existing entry?
• Pradeep: I mean after last year, do we have to register every year? I guess so..
• Gian Bernardo: lost
• Kirk: ha, no problem
• Tom: but new entry or existing entry?
• Kirk: we are writing a paper about our satellite for the International Astronautical Congress in India in September, www.iac2007.org.in
• Kirk: not sure Tom, you'll have to ask someone at IAC about that
• Geoff: eh, we sign up as authors?
• Kirk: yes
• Geoff: okay
• Tom: there is no seds in the list of entries...
• Tom: /companies/organizations
• Kirk: what entries?
• Tom: should I create a new entry?
• Leah left the room.
• Kirk: where?
• Tom: on the "joins us" form
• Tom: you have the choice between private/existing/new entry
• Lavina: * Organisation: Please select this option. Private individual Existing entry New entry
• Lavina: there
• Lavina: so which?
• Kirk: private individual
• Lavina: new?
• Tom: shouldn't we be registered with seds maybe?
• Kirk: no, I think that is for IAF member organizations
• Lavina: Thats what I was thinking
• Lavina: oh
• Kirk: they pay fees to be listed as a member org
• Lavina: We're not an IAFmember org?
• Lavina: ah
• Lavina: I see
• Kirk: the American Astronautical Society will be our member org for this paper
• Lavina: alright
• Kirk: they will "sponsor" us to IAC
• Lavina: so private/individual?
• Kirk: yes
• Geoff: oh! so our money issue is resolved? 0.o
• Tom: ok so the abstract is to be finalized at the next meeting
• Tom: please make any changes you feel necessary during the next week
• Tom: and then we'l discuss it at the next meeting
• Tom: nex up there is the payload conference with prof Murthy
• Lavina: oh?
• Tom: could you tell us a bit more about this Kirk?
• Tom: do we have a set time yet?
• Leah entered the room.
• Kirk: no, Pradeep will ask him for a time that is suitable
• Tom: ok
• Kirk: but we have to give him a topic to discuss
• Tom: personally I will ask him about radiation concerns
• Tom: what we can do to minimize the effect of the radiation etc
• Tom: any steps we can take during the design of pcb/logic/systems that can minimize the damage done by radiation
• Pradeep: sorry, got discon. for a sec..
• Tom: also what kind of conditions we should design for temp, again radiation etc...
• Tom: I would also like to ask him about the possibility of using FPGAs for the implementation of the payload(or other subsystems)
• Lavina: FPGA's?
• Tom: field programmable gate array
• Tom: I can post something on my blog about it...
• Lavina: that would be good :)
• Lavina: I'm afraid thats something I know nothingabout
• Pradeep: Tom, just as a caution..
• Tom: it's the coolest tech ever, but I won't bore you with it now:-)
• Tom: yes
• Pradeep: he's a Professor who basically teaches theoretical Astrophysics..
• Tom: ah ok
• Lavina: nice
• Lavina: where does he teach?
• Tom: when payload was mentioned I thought he worked with payloads etc
• Pradeep: at Indian Institute of Astrophysics..
• Tom: what is his field?
• Lavina: I didn't know there was such a school
• Pradeep: he's doing the UV Telescope for India's AstroSat.
• Lavina: that is awesome
• Lavina: do we have him onboard as an advisor?
• Pradeep: yeah, well, even I didn't..
• Pradeep: yeah..
• Lavina: awesome
• Lavina: This makes me want to study in India
• Tom: ok
• Tom: does anyone else have anything they want to ask him?
• Lavina: Nothing I can think of at this moment
• Pradeep: Tom, please take a look at this -home page - before you send him mails asking questions...
• Tom: lets all try and come up with something for next meeting then
• Pradeep: otherwise, all you would get is - "not sure about that" sort of replies..
• Pradeep: and I think he's travelling too...I'll try to call him and check..
• Tom: ok
• Tom: I see he's doing UV imaging
• Tom: that would be interesting
• Tom: I'm sure I can find some questions to ask about that:-)
• Pradeep: he advised me against going for that..
• Geoff: what about the orbit?
• Pradeep: when I asked him about it..
• Geoff: we still haven't concluded on that, have we?
• Lavina: no we haven't
• Lavina: although I was under the impression that the orbit depended on the primary payload
• Geoff: right
• Lavina: primary payload of the launch rocket that is
• Geoff: I mean, I'm for the LEO, but it is very poluted already..
• Tom: I'm still under of the opinion that we need to have a working orbit to be able to develop any systems or do any kind of design
• Tom: as we established last time, there should be more than enough space:)
• Lavina: this is true
• Lavina: especially for concerns regarding communication
• Tom: many of our mission concepts seem very unlikely if we had an orbit further out
• Tom: esp GEO
• Lavina: and I've heard there's an issue about orbit pollution
• Tom: not to mention radiation
• Geoff: yeah
• Tom: ok but back to the task at hand
• Tom: tasks:-)
• Tom: any suggestions
• Lavina: tasks?
• Tom: for the communications I suggest the GENSO initiative, hopefully I will get an answer before then too...
• Tom: yes
• Lavina: GENSO is mostly ground.
• Lavina: I was talking about the comm system onboard
• Lavina: the range has to be taken into account for comm system design
• Tom: yes I wasn't referring to that actually:-)
• Pradeep: GENSO makes sense when you have only one University doing ground ops...since we have Universities across the globe why not use the ground that way?
• Tom: we would still potentially benefit from it as far as I can see
• Tom: we wouldn't have ground stations at every university that participates I would think..
• Tom: but then again, that is what needs looking into for next meeting
• Pradeep: we would have only 1 ground station?
• Tom: who is ground again?
• Pradeep: If I remember, Amrut.
• Tom: is it you or amrut?
• Tom: ah ok
• Lavina: amrut
• Kirk: we have had a few applicants, but will not choose a ground lead until March
• Pradeep: I believe he's been talking to Kirk about it..Kirk?
• Lavina: his univ offered ground
• Lavina: but I agree with Tom that we can use GENSO
• Pradeep: his college, I think..
• Tom: so ok let's put that up for next weeks agenda
• Tom: GENSO
• Lavina: the larger the network, the better
• Lavina: ok
• Tom: anyone else, COM, OBDH...?
• Pradeep: who's gonna do GENSO?
• Lavina: i think I brought it up with Kirk earlier, but do we have a criteria for approving applications
• Lavina: ?
• Tom: I have emailed someone about it, so hopefully I'll get more info about it
• Pradeep: Kirk had contacted someone at GENSO too and I believe we have something about GENSO....we can email it to you..
• Kirk: the plan is for the advisers to check the team placements
• Pradeep: we can have an outline on the Wiki as to who's applied and is in who's team...maybe?
• Kirk: I will do that to the email list
• Pradeep left the room.
• Tom: let's see if pradeep comes back...
• Tom: ok
• Tom: so nothing else then I assume..
• Tom: ok
• Tom: who wants to be the leader of next week
• Tom: 's meeting
• Lavina: *crickets chirp*
• Tom: any volunteers?
• Tom: that sounded a lot like volunteering to me lav
• Tom: :-)
• Kirk: everyone will have to do it :)
• Lavina: ...
• Lavina: hahaha
• Lavina: Ok ok
• Lavina: I volunteer for next week
• Tom: ok so you're in responsible for the agenda and running the meeting
• Geoff: :)
• Lavina: Yep :)
• Tom: I suppose that's it for today unless someone has anything else they wish to discuss
• Kirk: please everyone have a look at the "team handbook"
• Kirk: and I will send an email this week about organizing our team structure
• Tom: lav, remember to post the meeting on protoforge btw
• Lavina: Will do
• Lavina: Mind if I poke you from time to time during the week to make sure I'm doing everything right? :)
• Lavina: Kirk, when you say organising our team structure?
• Kirk: the whole project, i mean
• Lavina: Also, the "handbook" can we discuss what we want on there?
• Kirk: absolutely
• Kirk: when I add things to the wiki, I expect my words to be changed
• Kirk: I am just "version 1"
• Lavina: hehe, yep
• Lavina: alrighty then
• Lavina: should we do this now or next meeting?
• Kirk: it is up to our meeting leader -- when he is done, we can certainly discuss
• Tom: if we all look at it now, we'll have some opinions on it for next meeting maybe...
• Lavina: ok
• Tom: ok geoff will you do the honours of posting the chat transcript?
• Kirk: and meeting notes?
• Geoff: sure
• Geoff: :)
• Tom: ok then
• Tom: for the last few minutes I suggest that we discuss those orbits a bit more
• Tom: not to sound like a broken record here
• Lavina: hehe
• Geoff: lol
• Tom: but I feel it's vital to absolutely everytinh
• Lavina: do we have options for the launch?
• Tom: *g
• Geoff: I was to ask about that to someone-who's-name-escapes-me-but-is-in-my-e-mail, hadn't gotten around to it yet though
• Tom: ok
• Tom: if you ask me LEO sounds the most likely in almost every respect
• Geoff: absolutely, and I agree
• Tom: I'm not sure a cubesat in GEO is something you would want really
• Lavina: Say we plan for LEO. Would it still work in polar orbit?
• Tom: esp if it's remote sensing
• Geoff: but in case we have a chance for originality, I'd take it, if we could :)
• Tom: yes LEO is polar orb
• Tom: GEO is geostationary
• Lavina: oh, I see
• Tom: wikipedia:Orbit
• Lavina: sorry. sheepish and ignoran, I am
• Tom: scroll down to earth orbits
• Tom: np we're all here to learn:-)
• Tom: wikipedia:Earth_orbit
• Tom: it should be kept in kind that communications get more and more difficult the further out we get
• Lavina: yes
• Lavina: and with such a small satellite, I don't think we SHOULD go beyond LEO
• Tom: my thoughts exactly:-)
• Geoff: true
• Tom: it would effectivly eliminate most of our payload suggestions as well actually
• Geoff: namely?
• Tom: because of the low bandwith we would get
• Kirk: don't forget: we are confined to the available CubeSat launches
• Geoff: aye
• Kirk: so that will define our orbit
• Tom: most cubesats are 2400bps/1200bps
• Geoff: Okay, so shall we make the exec decision of LEO then?
• Lavina: aye
• Geoff: aye
• Tom: and if you set up a link budget for that and change the orbit to 35,786 km you will se what I mean
• Tom: :-)
• Lavina: that way, we can hitch onboard a rocket that goes for LEO
• Geoff: yea
• Lavina: I'm guessing this decision should go onto Protoforge
• Geoff: good point
• Geoff: hmm, let's wait until next week's meeting, I'll probably have gotten an answer about launches
• Tom: who are you talking to about that anyway?
• Tom: cal poly?
• Geoff: eh, I forgot, honestly, but the name or org is in my e-mail somewhere
• Geoff: or heck, care for a quick reminder Kirk?
• Kirk: yes, it is Cal Poly
• Kirk: cubesat.calpoly.edu or cubesat.org
• Tom: have we asked ESA?
• Geoff: I haven't
• Tom: what about Lars?
• Lavina: Lars?
• Geoff: yeah, Lars?
• Tom: there were cubesats onboard the sseti express launch
• Tom: a guy in sseti
• Lavina: oh
• Tom: an ESA student satellite program
• Tom: maybe we could hitch a ride with eseo...
• Tom: kirk?
• Kirk: please, ask everyone for opportunities
• Kirk: it does not hurt to ask
• Kirk: launches are hard to find
• Tom: ok, I'll ask him if he gets back to me on the genso thing
• Tom: and I can ask someone I know at esa too
• Kirk: you have permission to ask -- my request is that you give the info to the group when you do ask, then give us the response
• Tom: ok
• Tom: might be in norwegian though, so some translation might be needed:-9
• Lavina: hehe
• Tom: I know the guy coordinating YES for esa, so I could ask him
• Geoff: cool :)
• Tom: ok so we'll all do that for next week then...if anyone know anyone to ask for launches...please do
• Tom: *knows
• Geoff: is NASA an option?
• Tom: if you have any contacts any aerospace agencies etc in you country/region
• Tom: have we asked them already? Kirk?
• Lavina: I'll ask the Department of Sci and Tech here to see if we can work with China
• Tom: good idea:-)
• Geoff: :) nice
• Tom: ok so shall we call an end to this meeting then?
• Lavina: fine by me :)
• Tom: I need to call my mother:-9
• Lavina: aw
• Tom: :)
• Lavina: hehe
• Tom: ok bye guys
• Lavina: bye Tom
• Tom left the room.
• Lavina: Do you guys want to discuss what should be in the Team Handbook?
• Geoff: sure
• Lavina: Leah and Gian, since you're new you might want to give your input. Your questions can serve as FAQ
• Lavina: ;)
• Kirk: SEDSAT-2 Team Handbook
• Lavina: Thanks, Kirk
• Lavina: Alright
• Lavina: my first thought is that Aaron's thing on requirement ownership should bein the handbook too
• Lavina: and basically, what Protoforge is for and how to maximise its usage
• Lavina: I mean to say, a shorter summary :)
• Geoff: beyond what's in the Tools spot?
• Lavina: Well, what's in the Tools spot are links
• Leah: a short introduction on protoforge will be helpful
• Lavina: Yep
• Lavina: A brief one, and then if people want to go more indepth, they can follow the link
• Lavina: er, when people have more time to go indepth
• Lavina: Since the team handbook is comprehensive, we should have GoTo persons as well
• Lavina: basically, for permissions or questions, we should have someone
• Geoff: hehe
• Geoff: true
• Lavina: Kirk's request that we should have at least one post a week should be mentioned under Blogs
• Geoff: yea
• Lavina: Meeting venues should also be explained, i.e., MSN or Y!M and what the protocol is behind that
• Lavina: also, Kirk, wasn't there supposed to be a website?
• Lavina: hello?
• Kirk: SEDSat-2
• Kirk: (sorry, a little busy now)
• Lavina: hehe
• Kirk: (but still here0
• Lavina: that's ok
• Lavina: alrighty.This means we need to assign someone to make the site
• Kirk: if you know someone to do it, I'll happily give it up
• Lavina: hmm
• Lavina: Maybe we should post a general announcement in the handbook and the groups asking for volunteers
• Lavina: I'm not very savvy with website design
• Kirk: probably not to the handbook, but we can include it in all future team recruitments
• Lavina: ah, ok
• Kirk: yeah?
• Kirk: no?
• Lavina: yeah, you're right
• Lavina: but the handbook should mention the site?
• Lavina: and possibly instructions for whoever becomes the webmaster?
• Lavina: oh and one last thing. I saw discussion in the list about software we could use. Should we put those options in the handbook?
• Kirk: sure - add it to "tools'
• Kirk: good idea
• Lavina: well, thats everything I can think of. Geoff?
• Lavina: Anything?
• Lavina: Leah?
• Geoff: I'm good
• Geoff: :)
• Kirk: post on the blog! :D
• Geoff: :P yessir
• Lavina: this discussion you mean?
• Lavina: or generally?
• Geoff: generally
• Geoff: hehe
• Lavina: hehe ok
• Lavina: Alright. I need to go. I have a ton of work to finish before bed, hehe
• Geoff: ditto, :)
• Geoff: ttfn then, until next week!
• Kirk: ok -- talk to you all later
• Lavina: ok
• Lavina: good luck all
• Lavina: see you :)
