1227.60 MHz. C/A code and carrier phase filtered measurement.
Update rate 1, 5, 10 Hz
RTK speed accuracy 0.16 kph (0.10 mph)
RTK position accuracy Horizontal 2.5 cm (0.98 in) + 2 ppm, 2 sigma, and vertical 3.7 cm
(1.46 in) + 2 ppm, 2 sigma, if all of the following criteria are met:
• At least 5 satellites
• PDOP <4
• CMR corrections
• Standard format broadcast from a Trimble MS750, AgGPS 214,
or equivalent reference station
Differential speed
accuracy 0.16 kph (0.1 mph)
Differential position
accuracy Less than 1 m (3.28 ft) horizontal if all of the following criteria
are met:
• At least 5 satellites
• PDOP <4
• RTCM SC-104 corrections
• Standard format broadcast from a Trimble MS750, AgGPS 214 ,
or equivalent reference station
OmniSTAR HP speed
accuracy 0.16 kph (0.1 mph)
OmniSTAR HP position
accuracy 10 cm (3.94 in) after convergence, 2 sigma, if all the following
criteria are met:
• At least 5 satellites
• PDOP <4
• OmniSTAR HP corrections
Convergence time can vary, depending on the environment. Time
to the first fix (submeter accuracy) is typically <30 seconds; time
to the first useable fix (<10 cm accuracy) is typically <30 minutes.
Time to first fix <30 seconds, typical
