[14:26] kristiianpaul: sige sampler [14:26] from sparkfun [14:30] software correlator in c/matlab [14:30] ooo [14:30] Laurenceb: you'd be interested in these vaisala radiosondes [14:31] they have a ublox gps frontend, and they send the samples down via the radio link [14:31] and all teh correlation is done in software on the ground [14:31] interesting [14:31] what frontend? [14:31] so they just bent-pipe the L1 freq? [14:31] uNav something [14:31] hold [14:31] Laurenceb: wow the expensive one :-) [14:32] are yo running the correlator in a emdebbed device? [14:32] The GPS receiver is a uBlox uN8021 RF front-end, which demodulates the GPS L1 signal, and sends samples to the micro-controller. This module is controlled via SPI on a shared bus, and also provides a 16.3676MHz clock signal to the rest of the board. [14:32] your correlate in real time or just take sample first? [14:32] http://web.archive.org/web/20051104225845/www.unav-micro.com/pdf/03_11_17+uN8021C+Final+DS.pdf [14:32] is you code pubnlically avaliable and freely/copyleft licensed? :-) [14:32] you can easily sniff the SPI bus [14:33] would be cool to write a correlator in C [14:33] oh sweet [14:33] osgps have implemented the gp2021 correator in C btw [14:33] kristiianpaul: its from kia borre [14:33] with some fixes by me [14:34] interesting - so osgps now have an open receiver framework?

[14:37] im guessing it takes samples of a few tens of ms of data, then sends them over the radio [14:37] yup [14:38] theres nowhere near enough bandwidth to stream the gps [14:38] Laurenceb: btw http://gnss-sdr.ru/index.php?blogid=2 [14:38] we use sondemonitor to decode the data [14:38] in case you have a maxim EVB to playwith, as i dont :( [14:38] ok so does it just send the bitstream then? [14:38] per sat, that is [14:38] ermoode: not exactly [14:38] youll run a correlator on the raw data [14:39] find pseudorange and doppler [14:39] no [14:39] find poddler only even [14:39] *doppler [14:39] ah you got the borre book i see [14:39] as its only used for wind aiui... in which case you needs milliseconds of data only [14:40] kristianpaul: yes, the book comes with a cd of useful code examples [14:40] we get position information to about 70m accuracy [14:40] Darkside: with sondemonitor? [14:40] yup [14:40] which is opensource? [14:40] no [14:40] sadly [14:40] ah i see - its from vaisala? [14:40] nope [14:41] google sondemonitor [14:41] its by a guy named bev [14:41] he spent aaaaaaages reverse engineering teh vaisala protocol [14:41] intriguing [14:41] good bloke [14:41] DPS whiz [14:41] DSP* [14:41] he comes to SA every year [14:42] so hes implimented the gps ?! [14:42] and he's very responsive to feature requests - i got him to add some stuff to the GPS output [14:42] yes [14:42] oh dsp whiz indeed :P [14:42] thats some pretty insane work [14:42] i coded an interface between that program and our existing balloon tracking software [14:42] so it plots a digisondes position on oziexplorer, and does live predictions [14:43] helps a lot when tracking them [14:43] actually there is one descrete logic opensource gps...

[16:32] ..how do you guys usually measure the helium when filling balloon? [16:32] the amount i mean, of how much has been released from the bottle already [16:33] simhed: measure the lift of the balloon. [16:34] i thought about doing it this way.. but also, are there any devices i could mount on the bottle itself, like flow meters? [16:38] yes. [16:38] They're several hundred times more expensive than a scale. [16:40] simhed it's a thorny subject in amateur ballooning, there's no cheap way to precisely measure the actual moles of helium in a balloon, other than measuring lift force [16:40] Which is very poor if you're not in calm air [16:41] I'm actually hoping to find some people who will experiment with using Kinects or similar 3D rapid scanners to live calculate the volume of a balloon on the launch pad [16:42] m1x10 (m1x10@ppp046177252174.dsl.hol.gr) left irc: Ping timeout: 276 seconds [16:42] The problem is that in wind, a balloon does not have zero lift [16:43] you could ask to borrow a mass flow meter if you actually want to know [16:43] we've got one as a permenant loan [16:44] but if not just measuring list will usually do the job [16:44] lift* [16:45] m1x10 (m1x10@ppp079166155129.dsl.hol.gr) joined #highaltitude. [16:48] RocketBoy (~steverand@217.47.75.8) joined #highaltitude. [16:48] Nice eroomde, having that flowmeter is handy [16:49] can't you use a simple string/meter tape tied around the diameter the balloon to measure volume? [16:49] If the balloon manufacturers would put an even grid inked on the balloon we could do it with simple photography [16:49] assuming it's a sphere, yeah [16:49] but it isn't [16:49] is the shape repetible? [16:50] depends on the fill and the age and manufacturer of the balloon [16:50] that's all you need, because you could tune it with pull [16:50] and the wind loading [16:50] Ah BrainDamage you haven't launched a balloon in the wind - it is a highly changing shape that folds and billows [16:50] ok, not repetible them [16:50] then* [16:50] too many variables to get a better estimate than just measuring lift, i would think [16:57] m1x10 (m1x10@ppp079166155129.dsl.hol.gr) left irc: Ping timeout: 246 seconds [17:00] jiffe (~jiffe@nsab.us) joined #highaltitude.
