altos: Bounds check Skytraq GPS tracking data array

2010-09-02T02:53:24+00:00

Missing GPS serial data could cause the tracking array reset to get skipped, causing the array to be overrun, smashing critical data beyond the array. This was detected using the 'altosui' flash command to program a device from TM. Hitting the USB that hard caused TM to crash with a mutex error (3 beeps) after the ao_gps_task structure was overwritten with zeros. Signed-off-by: Keith Packard

Log GPS data on pad after boost detect.

This wakes up the two GPS reporting tasks and gets them to report out any existing GPS data to the log file. To make sure the timestamps in that GPS data are accurate, this also records GPS time on receipt of the GPS data instead of when that is logged. Signed-off-by: Keith Packard

Stop using SiRF state info.

With the switch to the skytraq GPS unit, we don't have the same level of detail in the GPS stream, so stop reporting that in the telemetry stream, in the UI and writing it to eeprom. Signed-off-by: Keith Packard

Add date to GPS data, captured from GPRMC packet.

2009-11-16T00:19:52+00:00

Pull the date out of the GPS stream and send it over the telemetry link and write it to the eeprom. Signed-off-by: Keith Packard

Add support for the SkyTraq GPS unit

2009-10-10T05:02:40+00:00

This is a build-time option selected by hacking the Makefile at present. Signed-off-by: Keith Packard

Handle GPS satellite tracking data

2009-08-19T05:35:15+00:00

SiRF message #4 includes signal strength and GPS engine state for each of the satellites being tracked. This data is now parsed and sent to eeprom and the radio. Signed-off-by: Keith Packard

Add AO_GPS_RUNNING state.

This tracks whether the GPS receiver has ever sent a valid report to the flight computer, allowing the user to tell whether the GPS receiver is working at all. Signed-off-by: Keith Packard

Use 57600 baud for GPS. Clean up gps init.

2009-07-18T02:23:10+00:00

Assume GPS is either in 4800 NMEA or 57600 SiRF mode, send just the sequence to get from 4800 NMEA to 5760 SiRF. Also, eliminate threads from the gps test program. Signed-off-by: Keith Packard

Fix up SiRF parsing and test code so that it actually works
