Andrew Tridgell 05194ed8b6 AP_GPS: don't accept infinite accuracies for blending 
these result in NaN values for velocities
 2020-11-24 12:00:41 +11:00
Andrew Tridgell a762926526 AP_GPS: fixed constrained NaN in EKF3 caused by bad GPS blending 
if the accuracies reported are very low then we can do a division by
zero and this results in a constraining NaN for GPS vertical velocity
filter in NavEKF3_core::calcGpsGoodToAlign

Andrew Tridgell e995a198bd AP_GPS: always send GPS2_RAW if 2nd GPS configured 
this improves the display on the GCS when the GPS has not yet been
found. This is particularly important after a reboot, as otherwise the
GCS may display stale information from the previous boot
 2020-10-06 16:48:19 +11:00
Andrew Tridgell 94670879f8 AP_GPS: allow hwdef.dat override of GPS rate 2020-09-09 06:35:50 +10:00

Andrew Tridgell 5647aadbcf AP_GPS: added API for getting last iTOW 2020-09-09 06:35:50 +10:00
Andrew Tridgell 87c7781be2 AP_GPS: show GPS as unhealthy if it is lagged too much 
this detects GPS data lag, and if 5 samples in a row are lagged by
more than 50ms beyond the expected lag for the GPS then we declare the
GPS as unhealthy.

This is useful to detect users who have asked for more data from the
GPS then it can send at the baudrate that is being used. The case that
led to this path was a F9 GPS with GPS_RAW_DATA=1 at 115200 baud. In
that case the UART data is quickly lagged by over 1s

Tom Pittenger 8f6e9caf93 AP_GPS: change GPS_AUTO_SWITCH #define list to enum class 
enumeration entry had to change to NONE to avoid name conflict with DISABLED
 2020-06-25 11:10:31 +10:00
Andrew Tridgell 78858bbcdd AP_GPS: switch ublox over to 230400 baud 
this ensures we have sufficient bandwidth for raw data
 2020-06-01 17:18:17 -07:00
Andrew Tridgell 529bfe8fcd AP_GPS: fixed issue with GPS selection for moving baseline 
when you have a moving baseline pair of ublox GPS modules and the
rover GPS does not have full fixed RTK lock on the base GPS then we
should not use it as our primary GPS as it's position and velocity can
be badly affected by the attempts of the GPS to gain a fixed lock.

This was observed in a flight with two F9P GPS, where the GPS velocity
data from the rover GPS went way off when it lost full RTK lock. It's
status stayed at 4, so it was selected as the primary GPS

Andrew Tridgell 4f591a338f AP_GPS: use GCS_SEND_TEXT() 2020-04-29 07:36:55 +10:00
Andrew Tridgell f3a5d915f3 AP_GPS: allow for larger average delta on MB rover than normal 2020-04-21 15:30:54 +10:00
Andrew Tridgell 36098c3221 AP_GPS: improved delay health threshold 
allow for missing frames without showing unhealthy on GCS
 2020-04-21 15:30:54 +10:00
Andrew Tridgell 7027eecd34 AP_GPS: added GPS_DRV_OPTIONS 
this allows for configuration of moving baseline with either uart1 or
uart2 for the RTCM data. Using uart2 requires an extra cable between
the two modules, but requires less uart bandwidth which is good when
DMA channels are low. Using uart2 also avoids the rtcmv3 parser, which
saves memory

Andrew Tridgell 077ab22767 AP_GPS: fixed AP_Periph build with gcc 9.x 2020-04-01 17:08:48 +11:00

Andrew Tridgell 9fa034d1de AP_GPS: fixed antenna offset for blending 
we were accessing beyond the end of the antenna_offset array
 2020-03-17 12:13:54 +11:00
Randy Mackay a19634b9d2 AP_GPS: reduce POS param range to 5m and add increment 2020-02-01 08:46:03 +09:00
Andrew Tridgell f0d1d3fa90 AP_GPS: added get_semaphore() 2020-01-16 20:36:54 +11:00
Andrew Tridgell db777c56b9 AP_GPS: provide yaw feedback in GPS_RAW_INT and GPS2_RAW 
allow GPS to display status of GPS yaw for moving baseline and NMEA
 2020-01-07 12:37:35 +11:00
Andrew Tridgell e660532f67 AP_GPS: fixes from PR review 2020-01-07 12:37:35 +11:00
Andrew Tridgell b86c43aa66 AP_GPS: prefer RTK MB rover when it has yaw available 
this ensures that yaw data is time aligned with position and velocity
data
 2020-01-07 12:37:35 +11:00
Andrew Tridgell 261465ef96 AP_GPS: split out update_primary() from update() 
this makes the selection of primary GPS a lot clearer, with less
nesting of if statements
 2020-01-07 12:37:35 +11:00
Andrew Tridgell 93aaf98672 AP_GPS: added automatic u-blox moving baseline configuration 
this uses GPS_TYPE and GPS_TYPE2 to setup two u-blox F9 receivers in a
RTK moving baseline configuration
