Positioning specifications
Applicable receivers: BD990 | BD992 | BD992-INS | BX992
NOTES –
-
The following specifications are provided at 1 sigma level when using a Trimble Zephyr 3 antenna. Add 1 ppm for RTK position accuracies. These specifications may be affected by atmospheric conditions, signal multipath, and satellite geometry. Initialization reliability is continuously monitored to ensure highest quality. Trimble RTX and OmniSTAR accuracies depend on the correction service chosen.
-
Trimble CenterPoint RTX provides <4 cm horizontal accuracy 95 % of the time with initializations of less than 5 minutes when all constellations and signals are used.
-
Also available in configurations with RTK accuracies limited to 10 and 30 centimeters.
