The accuracy values listed in the r10 and SPS985 etc datasheets

Real-Time Kinematic (RTK) Positioning3

Horizontal accuracy. . . . . . . . . 8 mm + 1 ppm RMS (0.026 ft + 1 ppm RMS)

Vertical accuracy . . . . . . . . . . . .15 mm + 1 ppm RMS (0.05 ft + 1 ppm RMS)

Are they 95% confidence interval or some other confidence interval?? I cant seem to find the answer at the moment

Hey Josh

By definition RMS precision is as follows:

68% for 1 dimensional precision (ie. vertical measurements)

63% for 2 dimensional precision (ie. horizontal measurements)

See: Accuracy - Navipedia
