Trimble and the Globe & Triangle logo are trademarks of Trimble Navigation Limited registered in the United States and in other countries. The RINEX converter will then correctly adjust the height down to ARP. Trimble antennas have an antenna gain of 50 dB and a maximum suggested cable loss of 12 dB for a total of 38 dB system gain, so the Gain Amplification should be set to Disabled. 0 Trimble and one of . A helix based, triple-frequency L-band antenna ideal for UAV applications due to its lightweight, small form factor and low power consumption design. This setting is only applied at the base station in the generation of correction messages (CMR or RTCM). 0000076000 00000 n The GNSS receiver reduces all of the measurements at the L1 and L2 Antenna Phase Centers to the Mechanical Antenna Phase Center.

When the antennas at opposite ends of relatively short baselines are identical, these variations should cancel out and no effect is seen. One thing I do is tighten up the tolerances first: tighten up the number of points created with the project settings>computations>Surface>breakline approximation parameters. We have access to a RTK network (single base stations). Refer to the following diagram where (1) is the Trimble R10 receiver, (2) is the bottom of the antenna mount, (3) is the bottom of the quick release, (4) is the corrected height to the APC from the bottom of the pole.
