No reason not to let the GPS report solutions whenever it likes, let's see how this works. 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

Switch to 57600 baud for GPS data

2009-07-18T08:04:39+00:00

Reset GPS at boot time

2009-07-18T05:11:03+00:00

Allow the GPS port to run at 4800 baud if desired

2009-07-18T04:34:13+00:00

Initialize the GPS serial protocol state

Add AO_GPS_RUNNING state.

2009-07-18T04:32:17+00:00

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.

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
