[10:55] <jcoxon> hey defy, you there?
[11:18] <defy> hey, yeah
[11:19] <jcoxon> cool
[11:20] <jcoxon> you know the time in your gpsparser
[11:20] <jcoxon> how could that be changed to gps time
[11:21] <defy> you mean like just a standard date format?
[11:21] <defy> or the time from the gps?
[11:21] <jcoxon> at the moment its unix time isn't it?
[11:22] <jcoxon> i'd really like the gps time
[11:22] <defy> its a unix timestamp, easy enough to convert to a normal format, but just as easy to change completely in the parse
[11:22] <defy> r
[11:23] <defy> i've actually changed the parser a bit, on startup now it checks the gumstix date and time and sets it via the gps if its not above 1 billion, which was some time in 2004 i believe
[11:23] <jcoxon> oooo thats a good idea
[11:23] <jcoxon> the parser itself has simplified my system so much
[11:24] <defy> I'll throw it online, it still logs the unix timestamp but you could reformat it pretty easily
[11:24] <jcoxon> cool thanks
[11:24] <defy> cool :)
[11:24] <jcoxon> my radio modems aren't going to get here for another week
[11:24] <defy> oh that sucks
[11:24] <jcoxon> so i don't think they are going to go on peg III
[11:24] <jcoxon> not worth the risk of things going wrong
[11:25] <jcoxon> need time to test them
[11:25] <defy> true, have you got a set date?
[11:25] <jcoxon> well the launch window opens on friday
[11:25] <jcoxon> but i'm not sure the others will be ready till next week
[11:26] <jcoxon> its going to be very simple my payload
[11:26] <defy> cool
[11:26] <defy> going with cell for now then?
[11:26] <jcoxon> literally a camera, gumstix, phone, batteries and cutdown
[11:27] <jcoxon> yeah
[11:27] <jcoxon> though i was never going to abandon it
[11:27] <jcoxon> just use it for a solid backup
[11:27] <defy> cool
[11:27] <defy> http://defy.net/balloon/files/gpsparser.txt
[11:28] <defy> that should set the gumstix date correctly when it first starts
[11:28] <defy> doh, theres also 3 lines at the bottom that you can remove
[11:28] <defy> open(FILE, ">/tmp/wp_current_location");
[11:28] <defy> print FILE "$time:$lat:$long:$alt$altunits:$speed:$heading";
[11:28] <defy> close(FILE);
[11:29] <defy> thats just part of my waypoint sequencer
[11:31] <defy> were you wanting a readable format also? or just for the timestamp to be correct?
[11:33] <jcoxon> its more for the readable format
[11:33] <jcoxon> so when it is sent as a sms its easy to interpret
[11:34] <defy> just a sec ill change it around for ya
[11:34] <jcoxon> oh cool
[11:34] <jcoxon> thanks
[11:35] <jcoxon> i was slowly working my way through it but you are saving me a lot of time!

[11:45] <defy> is now the output
[11:45] <defy> obviously you can edit the day/month lists and the format to your own liking
[11:46] <defy> just change that last print line
[11:47] <jcoxon> thanks defy
[11:48] <defy> microperl on the gumstix seems to act very strangely, I cant seem to pipe the output of any cmd line programs back into a variable, otherwise it would be easier just to log the `date` command in there
[11:48] <jcoxon> odd
[11:49] <defy> oh well, it still works
[11:50] <jcoxon> :-)
[11:51] <jcoxon> nice not to have to fight with gpsd
[11:51] <defy> hehe
[11:51] <defy> you still have all the flight data from your other flights right? you should map it out with google earth :P
[11:53] <jcoxon> yeah i guess so
[11:53] <jcoxon> what format is required?
[11:59] <defy> kml, google earths version of kml i guess
[11:59] <jcoxon> i might try it this afternoon
[11:59] <defy> its just a couple of lines, then the course in "lat,lon,alt lat,lon,alt", then another couple of lines
[12:00] <defy> I just created a path in google earth, then saved it as a kml and read it's source, then made a perl parse that duplicated it with the new coords
[12:00] <jcoxon> right well i have lat lon and alt
[12:01] <defy> should be easy then :)
[12:01] <jcoxon> right i better get some lunch :-)
[12:01] <jcoxon> thanks for all the help defy
[12:01] <defy> no prob
[12:01] <defy> ttyl
