Andrew Tridgell feb9e78f00 AP_GPS: prevent switching to a dead GPS 
when we switch away from the blended GPS instance we need to ensure we

Peter Barker c9699d7ce4 AP_GPS: log GPS primary change event in GPS library 2021-08-06 15:30:18 +10:00
Andrew Tridgell 0e7c2a27a6 AP_GPS: added arming checks for yaw available on ublox RTK rover 2021-07-30 06:51:21 +10:00
Andrew Tridgell e5d878eebd AP_GPS: change handling of moving baseline yaw 
this changes yaw handling in a few ways:

 - GPS yaw now has a timestamp associated with the yaw separate from
   the timestamp associated with the GPS fix

 - we no longer force the primary to change to the UBLOX MB rover when
   it has a GPS yaw. This means we don't change GPS primary due to GPS
   loss, which keeps the GPS more stable. It also increases accuracy
   as the rover is always less accurate in position and velocity than
   the base

 - now we force the primary to be the MB base if the other GPS is a
   rover and the base has GPS lock

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

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 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

Michael du Breuil d623da0de6 AP_GPS: Always send GPS2_RAW after we've seen the second GPS 
This significantly improves the GCS's ability to correctly display whats
happening with the second GPS.

Michael du Breuil 5bafd7d72c AP_GPS: Don't defeat the GCS message interval code 2019-10-28 00:26:28 -07:00
Andrew Tridgell 14cdac9202 AP_GPS: fixed GPS to UART mapping 
this allows for first GPS as UAVCAN and 2nd as UART. That is not
possible currently unless you waste a uart
 2019-10-24 14:37:30 +11:00
Andrew Tridgell 00260db65a AP_GPS: fixed UAVCAN GPS status when disconnected 
this fixes the status reported for a UAVCAN GPS when the cable is
unplugged. It should be "NO GPS", but was instead reporting "NO
FIX". The user had no way to distinguish between not finding a CAN GPS
at all and it not getting satellites

thanks to CUAV for reporting

Grant Morphett 64ed76326b AP_GPS: Adding support for the NMEA GPHDT sentence 
The NMEA GPHDT sentence can be used to determine the vehicles bearing
instead of a compass even when the vehicle is stationary.  This type
of GPS is normally very expensive and does the bearing using some sort
of phase ambituity algorithm.
