[FOSS-GPS] RTKLib fixed baseline length

[Anthony Wooldridge]

Hi, RTKlib outputs the moving antenna position, not the polar vector from the base station, whether fixed base or moving.
However that vector is calculated somewhere in the software and is used in the graphical output of rtknavi. It would not take much programming change to output that vector, typically heading angle is the most useful from a moving base system. However the moving base solution is never as good as from a good fixed base, with sound physical reason, as there is less information to provide a solution.
A better way would be two fixed based solutions (2 rovers sharing one base) and manually extract the polar vector from the two solutions if that is what you need.
Regards Anthony
