@ -33,7 +33,7 @@ To navigate without GPS fix, we make the following assumptions:
- plane is flying in the direction where nose is pointing - plane is flying in the direction where nose is pointing
- (if pitot tube is not installed) plane is flying with constant airspeed, specified in settings - (if pitot tube is not installed) plane is flying with constant airspeed, specified in settings
It is posible to roughtly estimate position using these assumptions. To increase accuracy, plane will use information about wind direction and speed, estimated before GPS fix was lost. To increase groundspeed estimation accuracy, plane will use pitot tube data(if available). It is possible to roughly estimate position using theese assumptions. To increase accuracy, plane will use information about wind direction and speed, estimated before GPS fix was lost. To increase groundspeed estimation accuracy, plane will use pitot tube data(if available).
From estimated heading direction and speed, plane is able to **roughtly** estimate it's position. From estimated heading direction and speed, plane is able to **roughtly** estimate it's position.
