DGNSS/RTK BASE STATION POSITION BIAS DETECTION AND CALCULATION

Title:

DGNSS/RTK BASE STATION POSITION BIAS DETECTION AND CALCULATION

Document Type and Number:

WIPO Patent Application WO/2022/036614

Kind Code:

A1

Abstract:

Global Navigation Satellite System (GNSS) receivers can provide more accurate positioning when augmented using Real-Time Kinematic (RTK) or Differential GNSS (DGNSS) corrections. Techniques described herein leverage multi-constellation, multi-frequency (MCMF) measurements taken at a base station at first and second times to generate correction information that can be used to detect and correct a bias (or offset) in the location of the base station. This bias may be detected by a rover station, or by the base station itself.
