Samuel Tabor
ff1725b549 AP_Soaring: Make enable channel 3 position. PWM above 1400us allows most soaring features, but above 1700us is required before any automatic switch to LOITER mode. 2020-04-08 09:11:54 +10:00

2b40182b34 AP_Soaring: Reduce drift feed-forward by ratio of climb rate to thermal core strength. This is consistent with assumption that each packet of air, rising at core strength, is convected with the ambient wind speed. 2020-04-08 09:11:54 +10:00

650b464831 AP_Soaring: Move drift check to separate function and check drift with reference to mission segment, allowing drift in right direction. LOITER target, not current position, is now used. 2020-04-08 09:11:54 +10:00

75f772b269 AP_Soaring: Add SOAR_MAX_RADIUS parameter, that defines when a RTL will be used when exiting LOITER. 2020-04-08 09:11:54 +10:00
