Hi,
I am trying to get <10cm accuracy GPS position with the help of RTKLib
in kinematic mode.I have set up a rover using Trimble Bullet III
antenna.Both the rover and the base station use Skytraq S1315F-Raw
module at 10Hz.
As soon as I start RTKNavi the plot moves around for some time and then
stabilizes with a fix solution at a fixed point(within 20 cm).Now,if I
move the rover around,I get a corresponding respose from RtkLib too.So
far,so good.
However,if I stop and start rtknavi again,it stabilizes with a fix at a
new position even if the rover is at the same place.I have
attached herewith my configuration file that I am currently using.
Can anyone please tell me what I am doing wrong?
Regards
Nidhi
