[09:33] <edmoore> hi
[09:41] <Laurenceb> hello
[09:41] Action: Laurenceb has a corona rp4s1
[09:42] <edmoore> ?
[09:43] <Laurenceb> direct conversion 35MHz reciever for 35MHz
[09:45] <Laurenceb> has a range of several Km apparently
[09:45] <edmoore> DC = no IF?
[09:45] <Laurenceb> yep
[09:45] <edmoore> cool
[09:45] <edmoore> but that churns out some data
[09:45] <edmoore> bet*
[09:45] <Laurenceb> then uses a DSP to filter out the modulation
[09:46] <Laurenceb> its only an RC things
[09:46] <Laurenceb> *thingy
[09:46] <edmoore> ok
[09:46] <Laurenceb> but it should be good, I'm just fitting it on the rogallo
[09:46] <edmoore> cool :)
[09:46] <Laurenceb> I have the eeprom working
[09:46] <Laurenceb> http://wiki.ukhas.org.uk/code:i2c_eeprom
[09:47] <Laurenceb> it has a groovy "file system"
[09:47] <Laurenceb> theres 12 byte records
[09:47] <Laurenceb> you can do a binary search for the top of data
[09:48] <Laurenceb> and wipe the data by writing "magic" characters to every 12th location
[09:48] <Laurenceb> edmoore: I was thinking... you could do attitude determination with 3 lassen iqs
[09:49] <edmoore> and some massive booms?
[09:49] <Laurenceb> not really
[09:49] <edmoore> doppler velocity to give rates?
[09:49] <Laurenceb> 40cm or so
[09:49] <Laurenceb> you can get out phase
[09:49] <Laurenceb> relative to the pps
[09:49] <Laurenceb> of the carrier
[09:49] <edmoore> they use it on commercial airliners, I understand
[09:50] <Laurenceb> yeah, theres plenty of satellite systems
[09:50] <edmoore> you know better than me but i guess you could get much better data with some tightly couples processing on multiple processors
[09:50] <Laurenceb> well actually its a disadvantage having different clocks
[09:51] <Laurenceb> but once you get 4 satellites the clock errors should cancel out
[09:51] <Laurenceb> and you can find the attitude
[09:51] <Laurenceb> but its not really practical compared to magnetometers and accels
[09:51] <Laurenceb> just a fun project if you have money to burn :P
[09:52] <edmoore> :)
[09:52] <Laurenceb> the other thing I was thinking is an FPGA with a 32 bit core, fpu and correlators
[09:52] <Laurenceb> then a SE4120
[09:53] <Laurenceb> and 3 axis accels, gyros, magno and 4 thermopiles
[09:53] <Laurenceb> use the gps pseudoranges and doppler as velocity and position inputs
[09:53] <Laurenceb> the cool thing is you could test the concept with an ARM and the lassen
[09:54] <Laurenceb> in fact if it wasnt for the velocity lock you could use that setup instead
[09:54] <Laurenceb> as the lassen can give you doppler and pseudorange
[09:54] <edmoore> so basically a massively tightly coupled IMU?
[09:54] <Laurenceb> yes
[09:54] <edmoore> that would be *really* cool
[09:55] <Laurenceb> its doable on an arm
[09:55] <Laurenceb> - badger
[09:55] <Laurenceb> I looked at the benchmarks
[09:55] <edmoore> could you implement a full gps receiver on a not very special fpga?
[09:55] <Laurenceb> no problems
[09:55] <edmoore> i.e. the hardware end.. og actually you have that chip
[09:55] <edmoore> that spits out iq
[09:55] <edmoore> wow
[09:55] <edmoore> that would actually be a pretty 'kin awesome project
[09:55] <Laurenceb> I've seen it done on pro asic
[09:56] <Laurenceb> have you seen my imu matlab script?
[09:56] <edmoore> are there gps IP cores?
[09:56] <edmoore> nope
[09:56] <edmoore> you could end up with some *huge* matrices
[09:56] <Laurenceb> http://www.mibbit.com/pb/SthzfG
[09:57] <Laurenceb> not really
[09:57] <Laurenceb> no point, everyone uses arm
[09:57] <Laurenceb> without even an FPU
[09:58] <Laurenceb> you dont really need - most recievers dont even have a kalman filter
[09:58] <edmoore> but if you want to throw all the inertial data in, it will get big
[09:58] <Laurenceb> yes
[09:58] <Laurenceb> probably 15 state
[09:58] <Laurenceb> but its still doable
[09:58] <edmoore> ie.e tightly coupled in one stage, rather than a black box gps
[09:58] <Laurenceb> maybe not at hundereds of hz
[09:58] <edmoore> 50 would do
[09:58] <edmoore> virtex 5 DSP
[09:59] <Laurenceb> theres one of those being used for a passive SAR
[09:59] <Laurenceb> using reflected gps
[09:59] <Laurenceb> you'll need the data for that filter, just a sec
[10:00] <Laurenceb> http://pastebin.com/m53b6f56e
[10:00] <edmoore> yep
[10:00] <Laurenceb> that needs to be saved as rpy90bothways.TXT
[10:01] <Laurenceb> then beta=0.000004, alpha=0.01, q=0.00003
[10:01] <Laurenceb> it gives out a 3D graph tracing the ends of the x,y,z axes
[10:01] <Laurenceb> I find that easier to visualise
[10:01] <Laurenceb> its quaternoin based
[10:02] <Laurenceb> got the data from a guy on the sparkfun forum, using the sparkfun 6DOF IMU
[10:03] <edmoore> useful
[10:03] <Laurenceb> beta alpha and q are gyro, accel and process noise
[10:03] <edmoore> grand
[10:04] <Laurenceb> it assumes independant noise, so they are multipled by indentity matrices
[10:04] <Laurenceb> are you getting graphs?
[10:04] <Laurenceb> I've discovered its very easy to make extended kalman filters become unstable
[10:05] <edmoore> yes - if they don't have a nice prior and are initialised funny, they seem to explode
[10:07] <Laurenceb> if you set the lassen to output ephemeris, pseudoranges, doppler and time of transmission, its just some trig to get a observation space model
[10:07] <edmoore> can I ask you about gps RF?
[10:08] <edmoore> I am interested but ignorant
[10:08] <Laurenceb> i.e. you dont even need to solve it in the normal sence
[10:08] <Laurenceb> the kalman filter solves it
[10:08] <Laurenceb> go for it
[10:08] <edmoore> so... all sattelites use the same freq but some kind of spread spectrum scheme like cdma?
[10:08] <Laurenceb> yes
[10:09] <Laurenceb> 1023 bit spreader codes
[10:09] <edmoore> and the correlators are just running their mutually orthogonal codes looking for something rather than nothing?
[10:09] <Laurenceb> yes
[10:09] <edmoore> ok... so why not have 1024 correlators rather than 'millions' that you read in marketing bumph?
[10:09] <Laurenceb> you have to search in frequency space as well
[10:10] <Laurenceb> due to the doppler shift
[10:10] <edmoore> ah ok
[10:10] <edmoore> so just the more the merrier
[10:10] <Laurenceb> the pure correlator approach is frowned at by many
[10:10] <Laurenceb> there more funcy fourier stuff you can od
[10:10] <edmoore> go on...
[10:11] <Laurenceb> saerch in paralle in frequency space
[10:11] <Laurenceb> use the convolution theorem to search in pahse space
[10:11] <edmoore> what are you looking for in freq space?
[10:11] <edmoore> peaks?
[10:11] <Laurenceb> I wrote a script that can do acquisition in 20 seconds on my laptop
[10:11] <Laurenceb> yes
[10:12] <Laurenceb> I'll try and dig out my script
[10:12] <edmoore> ok, and how do you search the phase space?
[10:12] <Laurenceb> fourier
[10:12] <Laurenceb> freuency you multiply by a local oscillator
[10:12] <edmoore> so just multiply some FTs
[10:12] <Laurenceb> usually 500Hz intervals
[10:13] <Laurenceb> yes, you can calculate them beforhand
[10:13] <edmoore> so you multiply the FT by the 'FT' (presumably a delta function) of the output of a local oscillator
[10:13] <edmoore> the FT of the sampled signal at some bin
[10:13] <Laurenceb> and if you ned direct conversion I and Q then input the adc values as complex numbers its even easier
[10:14] <Laurenceb> no, local oscillator you do before the FT
[10:14] <Laurenceb> you "premultiply"
[10:14] <Laurenceb> by local osc
[10:14] <Laurenceb> then FT
[10:14] <edmoore> ok, and just FT the output
[10:14] <edmoore> ok cool
[10:14] <edmoore> i'm not really sure why that works, but fine
[10:14] <Laurenceb> then multiply by the convoluted FT of the code
[10:14] <Laurenceb> then IFFT
[10:14] <Laurenceb> repeat for each local osc and sat
[10:14] <edmoore> convolved, surely :P
[10:15] <edmoore> convoluted as it is
[10:15] <Laurenceb> yes
[10:15] <Laurenceb> freudian
[10:15] <edmoore> :)
[10:15] <Laurenceb> then you plot in 2D, z=mag,x=local osc, y=phase
[10:15] <edmoore> aaaah - and that's that plot you showed me
[10:15] <Laurenceb> well for graphical groovyness you do
[10:15] <Laurenceb> other wise use max
[10:15] <edmoore> with one big peak in the middle
[10:15] <Laurenceb> yes
[10:16] <Laurenceb> yep, that was the sat
[10:16] <Laurenceb> so you get phase and doppler of that to reasonable accuracy
[10:16] <edmoore> http://www.astron.nl/tl/thea/publications/Two_dimensional_256_Element_PAS.pdf
[10:16] <edmoore> have a look at fig 4
[10:16] <edmoore> that really floats my boat
[10:16] <Laurenceb> then use that to initialise the corrilator hardware
[10:17] <Laurenceb> then the CPU can bugger off and do something else
[10:17] <Laurenceb> use DMA or something groovy to get data off the correlators
[10:17] <edmoore> ok, so basically you just massive narrow your search space
[10:17] <edmoore> then set the correlators off on it
[10:17] <Laurenceb> on the pro asic design its actually memory mapped off the address bus
[10:17] <Laurenceb> yep
[10:17] <edmoore> aaaah
[10:17] <edmoore> ok this is cool
[10:18] <edmoore> right, i am a bit hung over so that's enough info to be getting on with
[10:18] <edmoore> but... this is cool
[10:18] <edmoore> thanks
[10:18] <Laurenceb> yeah, you can get pro asic with arm already on
[10:18] <Laurenceb> :P
[10:18] <edmoore> FPGA baby
[10:18] <edmoore> i want to play FPGA
[10:18] <Laurenceb> bu tI prefer spartan3
[10:18] <edmoore> yeah, it seems pretty cool
[10:18] <Laurenceb> my friend s using vertex for his SAR
[10:19] <edmoore> spartan 3 DSP... £20 and can be put on a 4 layer board
[10:19] <Laurenceb> - fellow phd
[10:19] <edmoore> that's big
[10:19] <Laurenceb> yeah, I plan to get an eval board
[10:19] <edmoore> cool
[10:19] <edmoore> right, well ed must dash

[10:30] <jcoxon> morning all
[10:34] <Laurenceb> hi jcoxon
[10:34] <jcoxon> hey Laurenceb
[10:34] <jcoxon> hows things?
[10:34] <Laurenceb> I was just reading the specs for my RC system
[10:35] <Laurenceb> and well... theoretically the range is ~15Km at altitude
[10:35] <Laurenceb> so we could guide down my rogallo
[10:35] <Laurenceb> with the RC
[10:35] <Laurenceb> especially if we rigged at yagi onto the transmitted
[10:36] <Laurenceb> it might get a bit big
[10:39] <Laurenceb> but yeah it all good
[10:39] <Laurenceb> you?
[10:40] <jcoxon> am in the library - got 4000 words to write this weekend, fun!
[10:40] <Laurenceb> :-/
[10:43] <Laurenceb> yeah ground control owrks
[10:43] <Laurenceb> thatds everything tested on the mini rogallo apart from the 434MHz
[10:44] <jcoxon> so a real test soon?
[10:44] <Laurenceb> hopefully in a few weeks
[10:49] <jcoxon> cool
[10:52] <Laurenceb> I need to find a way to do some glide tests
[10:52] <Laurenceb> and make a linux version of the flight control firmware
[10:52] <Laurenceb> to run with kml files
[10:58] <jcoxon> no AVR emulators available?
[11:14] <jcoxon> Laurenceb: hows the PhD going?
[11:18] <Laurenceb> not sure
[11:19] <Laurenceb> 99?
[11:28] <EI5GTB> morning
[11:30] <jcoxon> morning EI5GTB
[11:30] <EI5GTB> hiya
[11:35] <EI5GTB> how are things today?
[11:36] <jcoxon> not bad thanks
[11:36] <jcoxon> 400 words done, 1600 left for today :-)

[12:09] <edmoore> Laurenceb: what is the gps modulation scheme?
[12:09] <Laurenceb> hello
[12:09] <Laurenceb> I was going to go out
[12:09] <edmoore> hello :)
[12:10] <Laurenceb> but I'll chat for 5 :P
[12:10] <Laurenceb> erm its phase shift
[12:10] <edmoore> b/q?
[12:10] <edmoore> <b/q>PSK
[12:10] <EI5GTB> bbq?
[12:11] <Laurenceb> yes
[12:11] <Laurenceb> erm BPSK for the C(A) code on L1
[12:11] Action: Laurenceb gets a book off his shelf
[12:11] <Laurenceb> BPSK for the P(Y) - military at 3db bown on L1
[12:12] <Laurenceb> *down
[12:12] <edmoore> so BPSK wherever
[12:12] <edmoore> ok
[12:12] <edmoore> differentially coded?
[12:12] <Laurenceb> yes
[12:12] <edmoore> ok coool
[12:12] <Laurenceb> XOR the C(A) and the data
[12:12] <edmoore> C(A)?
[12:12] <Laurenceb> L2 is pure P
[12:13] <Laurenceb> Corse/civilian aquisition
[12:13] <Laurenceb> P is encripted precision code
[12:13] <edmoore> ok
[12:13] <edmoore> how encypted?
[12:13] <Laurenceb> L2 is 1227MHz carrier
[12:14] <Laurenceb> L1 1575MHz
[12:14] <Laurenceb> its a pseudorandom code I think 1 week duration
[12:14] <Laurenceb> you can crack it with a large dish
[12:14] <Laurenceb> gust dont publish it only if you want to live
[12:14] <Laurenceb> *just
[12:15] <Laurenceb> *online
[12:15] <edmoore> I can imagine
[12:15] <EI5GTB> i wondcer how accurate it is.,,
[12:15] <edmoore> accurater
[12:15] <Laurenceb> oh and the P code on L1 is 90 degrees out of phase
[12:15] <Laurenceb> but you wont be using it anyway
[12:16] <Laurenceb> you can ignore it pretty much
[12:16] <Laurenceb> in the script I used to get that acquisition plot I just pretended it want there
[12:17] <EI5GTB> Laurenceb, iv decided to not jump in at the deep end with UAVs, i guesse the best way to learn is to start simple..
[12:17] <Laurenceb> P is at 10.23MHz chip rate, C is 1.023MHz
[12:17] <Laurenceb> ok
[12:17] <EI5GTB> hence fixed wing aircraft are probablt tho most smart..
[12:18] <Laurenceb> or rogallos
[12:18] <Laurenceb> :D
[12:18] <EI5GTB> rogallo, sounds, different
[12:18] <Laurenceb> have you seen the photos on the wiki?
[12:19] <Laurenceb> edmoore: you'll need a code generator
[12:19] <Laurenceb> just a sec
[12:19] Action: Laurenceb delvs on his HDD
[12:19] <EI5GTB> Laurenceb, think so, yea
[12:19] <edmoore> Laurenceb: a code generator...
[12:19] <EI5GTB> easy enough made?
[12:19] <Laurenceb> for the C codes
[12:20] <edmoore> to generate all the orthogonal codes?
[12:20] <Laurenceb> I have them somewhere
[12:20] <Laurenceb> yes
[12:20] <edmoore> ok
[12:21] <Laurenceb> http://www.mibbit.com/pb/YNAoqY
[12:21] <edmoore> so Laurenceb - all of this is conceptually ok... but I guess that's just the RF front end and we've not done anything clever yet
[12:21] <Laurenceb> got it
[12:21] <Laurenceb> no point
[12:21] <Laurenceb> SE4120 and be done with it
[12:21] <Laurenceb> dont even need an LNA
[12:22] <Laurenceb> SE4120 ---> SPI
[12:22] <Laurenceb> oh and a TCXO for the 4120
[12:22] <edmoore> what is the data rate out of it?
[12:22] <Laurenceb> 16 Mbps
[12:22] <edmoore> that's fast SPI :)
[12:23] <Laurenceb> I'm using 10 on my mlx90609
[12:23] <Laurenceb> the sparkfun eval board uses a cypress 8051
[12:23] <Laurenceb> with usb
[12:24] <Laurenceb> apparently the SE4120 is hard to obtain
[12:24] <edmoore> uhuh
[12:24] <Laurenceb> and sparkfun have sold out of boards atm :/
[12:24] <Laurenceb> but there is something from Ti thats very similar
[12:25] <edmoore> it's pretty high bandwidth, C/A
[12:25] <Laurenceb> yeah 2MHz
[12:25] <edmoore> i guess it's SS though so that's what's expected
[12:25] <Laurenceb> did you see my plot of spectrum
[12:26] <edmoore> i think so but if you have it to hand...
[12:26] <edmoore> bbiab
[12:27] <Laurenceb> http://imagebin.org/31847
[12:27] <Laurenceb> the red in the background is with no antenna
[12:27] <Laurenceb> the full width is 8Mhz
[12:28] <Laurenceb> I suspect those peaks are clock lines on my laptop

[15:27] <Laurenceb> yes
[15:27] <Laurenceb> but the IF is 38 KHz

[19:12] <Laurenceb> I'm using a lamp to try and evaporate it
[19:12] <Laurenceb> asap
[19:13] <Laurenceb> hi edmoore
[19:13] <edmoore> yo
[19:13] <Laurenceb> looks like pva is the only good glue you can buy in thei country
[19:14] <Laurenceb> so much for advancement
[19:15] <Laurenceb> tomorrow morning first thing I'm going to go round and break this guys nose
[19:16] <Laurenceb> this sucks
[19:17] <natrium42> Laurenceb, you can only use odourless CA on foam
[19:17] <Laurenceb> nope
[19:18] <natrium42> the other CAs will eat it away
[19:18] <Laurenceb> there some cool chinese contact adhesive
[19:18] <natrium42> contact cement?
[19:18] <natrium42> you can get it in most hardware stores
[19:18] <Laurenceb> I had some UK stuff that was supposed to be equivalent
[19:18] <Laurenceb> so much for that
[19:18] <Laurenceb> not in the UK
[19:18] <Laurenceb> its crap here
[19:18] <Laurenceb> I'll have to stock up on some decent stuff online
[19:19] <natrium42> http://www.jamestowndistributors.com/userportal/woeimages/Adhesives/8671.jpg
[19:19] <natrium42> that one should also work
[19:19] <Laurenceb> I've got a load of that
[19:19] <Laurenceb> but its foaming
[19:20] <Laurenceb> yeah I guess I could use that to plug the huge holes in the top and round the antenna that are left now
[19:21] <Laurenceb> but this foam safe contact adhesive was perfect
[19:22] <Laurenceb> looks like you can only get it in china
[19:24] <Laurenceb> hmm aparently shoe repair stuff might work
[19:25] <Laurenceb> but I dont want to have to buy and try tons of products
[19:32] <Laurenceb> hmmm guess I can afford to leave it for the time being, and make do with foam safe CA/epoxy/gorilla glue
[20:07] <edmoore> Laurenceb: based on your experience of kalman filters at the low cpu end of the market, do you think 10bit adc is enough conversion for these low end sensors?
[20:22] <Laurenceb> probably
[20:22] <Laurenceb> if there is enough noise
[20:23] <Laurenceb> sorry, was away connecting up the cutdown
[20:23] <Laurenceb> I have a bit more respect for that n-prize guy who claims he can run a 9 state filter on a 8051
[20:24] <Laurenceb> but still dont see it happening
[20:35] <edmoore> he's *super* switched on, that guy
[20:36] <edmoore> he's designed missiles that do exactly that and they have very unspectacular cpus
[20:37] <Laurenceb> cool
[20:37] <Laurenceb> right radio is fully "integrated"
[20:38] <Laurenceb> just the wings to glue into their mouting holes and the cutdown cable to solder in - its glued onto the wings
[20:38] <Laurenceb> ground control work, eeprom can cause a hang under certain conditions, but I'm too tired to do any more debugging now
[20:39] <Laurenceb> oh and theres two bloody great holes dissolved in the top :(
[20:39] <Laurenceb> apart from that the rogallos coming on
[20:42] <Laurenceb> did you have luck with that matlab kalman filter?
[21:01] <Laurenceb> I'm reading the nebula page, v interesting attitude control approach
[21:02] <Laurenceb> differential throttling of diferent earospike injectors
[21:02] edmoore (n=edmoore@chu-gw.churchillcambridge.co.uk) left irc:
[21:03] <Laurenceb> oh nice, using common rail deisel injectors
[21:03] <Laurenceb> that guy is a genius
[21:16] <Laurenceb> hmm nitros oxide oxidiser

[21:55] <Laurenceb> you guys seen the palin turkey massacre?
[21:56] <natrium42> yes.
[21:56] <Laurenceb> pretty funny stuff
[21:57] <natrium42> it was pretty dumb of her to do the interview in front of that
[21:57] <Laurenceb> what do you expect from here
[21:57] <Laurenceb> *her
[21:57] <natrium42> indeed
