To ensure that a consistent height datum is available when switching between altitude sources, the WGS-84 height estimate of the EKF's local positi norigin is updated using a\nsingle state Bayes estimator,\n\nIf rngfinder or gps height data is lost whilst being used, there will be a fall-back to baro data.","distinct":true,"url":"https://api.github.com/repos/ArduPilot/ardupilot/commits/e6f36f04dba5a5bbe46ac26ea73e1f7364b456d7"}]}
