Silvan Fuhrer cedf14e2ba Airspeed Selector: repurpose wind estimator into an airspeed (selection, validation) module. 
This new airspeed module does:
  -runns an airspeed validator for every airspeed sensor present, which checks measurement validity and estimates an airspeed scale
  -selects another airspeed sensor if for the current one a failure is detected
  -estimates airspeed with groundspeed-windspeed if no valid airspeed sensor is present
  -outputs airspeed_validated topic

Matthias Grob 269d077fae ekf2: only check ground effect if it's configured 2019-04-30 12:34:28 +02:00
Roman f034d2da19 ekf2: fixed bug in baro ground effect triggering logic 
- when either terrain data was temporarily not valid (flying at high
distance to the ground) or the vehicle was not close to the ground
(_param_ekf2_gnd_max_hgt) the ekf switched to using the land detector
ground effect flag.

Paul Riseborough f8ae8ba502 ekf2: Use ecl library with recent bug fixes and enhancements. 
Bug Fixes:

https://github.com/PX4/ecl/pull/586 - EKF: fix covariance and output filter buffer initialization
https://github.com/PX4/ecl/pull/590 - EKF: Fix innovation in fuseDeclination()

Enhancements:

https://github.com/PX4/ecl/pull/543 - ekf_helper: add more useful methods to interface with the covariances
https://github.com/PX4/ecl/pull/588 - Add unit tests for DataValidator

Note:

https://github.com/PX4/ecl/pull/543  has required a change to how the state variances are accessed .

Paul Riseborough 72f85e4b2d ekf2: Handle blending of dissimilar rate GPS data (#10570) 
A filtered update update interval is calculated for each receiver.
If dissimilar interval data is detected, blending occurs when data is received from the slower of the receivers.
If similar interval data is detected, blending occurs when receiver data with similar time stamps is available.
If no data is received from either receiver for longer than 300msec, then no blending will be performed and the most recent data will be used instead.
