Paul Riseborough b459d937ad AP_NavEKF2: Clean up GPS fusion timeout logic and comments 2015-10-30 12:24:19 +09:00
Paul Riseborough 0b1a6a2157 AP_NavEKF2: Clean up GPS timeout logic 2015-10-30 12:24:06 +09:00
Paul Riseborough 74da4d8e57 AP_NavEKF2: Remove GPS glitch offset logic
Correction for steps in position and velocity caused by resets following GPS glitches and other events are now handled by the control loops.

Paul Riseborough b08817554e AP_NavEKF2: Ensure consistent position and velocity fusion rates when not using GPS
This sets the fusion of the synthetic position and velocity to occur at the same time as the barometer

This makes filter tuning more consistent between GPS and non-GPS useage

Paul Riseborough 1c347e8859 AP_NavEKF: Prevent high measurement data rates from overflowing buffers
High measurement data rates can fill buffers with data that is always new and never fused because it is over-written before it falls behind the measurement time horizon.

Paul Riseborough d1a090dda8 AP_NavEKF: Fix bug fetching data from measurement buffers
This bug can result in valid data being rejected and fused at the wrong time horizon.

Paul Riseborough ab8c28a7cc AP_NavEKF: Fix bug allowing takeoff in GPS modes without aiding
The legacy EKF switches GPs aiding on on arming, whereas the new EKF switches it on based on GPS data quality.
This means the decision to arm and therefore the predicted solution flags must now reflect the actual status of the navigation solution as it will no longer change when motor arming occurs.

Andrew Tridgell d1dfd5fd01 AP_NavEKF2: use common header for optimisation level and irq disable 2015-10-20 15:21:40 +11:00
Paul Riseborough 2fbd050418 AP_NavEKF2: Use blended accelerometer data
If high vibration levels cause offsets between the two, it switches to the accelerometer with lower vibration levels. The default behaviour is to use the average of both accelerometers.

Paul Riseborough 225b81baf4 AP_NavEKF2: Prevent users breaking filter by setting excessive time delays
If time deelays greater than the IMU buffer length are used, then it is possible for measurements to be dropped.
