priseborough 188bea6bab AP_NavEKF : Enable calc of wind velocity when not using airspeed sensing ... This patch also cleans up the logic associated with use of the synthetic sideslip measurement so that it can never be used for a non fly-forward vehicle type This patch adds functionality that initialises the wind-speed vector to the reciprocal of the ground speed vector, and scaled to 6 m/s. On average this gives a better initial wind velocity estimate on launch by assuming: a) launch will be into wind b) wind speed is equal to global average It also helps prevent a headwind causing initial underestimation of airspeed causing high autopilot gains and limit cycles on climb-out, until first turn when the EKF is able to estimate the wind.		2014-04-13 19:37:19 +10:00
