Problems solved by technology

However, transitions between real-time motion mode and relative positioning mode may be abrupt or cause jumps or discontinuities in the position of the receiver or the vehicle associated with the receiver
Also, after a real-time motion signal is interrupted, corrupted, or lost, in some prior art satellite rec...

Abstract

An offset module (130) or navigation positioning estimator (57) determines a reference frame bias between precise point positioning (PPP) reference frame and an RTK reference frame, where the PPP reference frame is associated with relative position estimates generated by the relative position estimator (124) and where the RTK reference frame is associated RTK position estimates generated by the RTK position estimator (122). Upon loss of the RTK correction signal, the navigation positioning estimator (57) or controller switches to a relative position mode based a last available RTK position. The relative position estimator (124) determines an estimated relative position based on time-differenced phase measurements by the mobile receiver (12, 30) in the relative position mode. The relative position estimator (124) or offset module (130) offsets the estimated relative position in the relative position mode.

Description

[0001] related application [0002] This document (including drawings) is based on U.S. Provisional Application No. 62 / 186,009, filed June 29, 2015, and U.S. Provisional Application No. 62, filed September 17, 2015, under 35 U.S.C. §119 / 219,880 of which the provisional application is incorporated herein by reference. technical field [0003] The present invention relates to a satellite navigation receiver and method for switching (seamlessly or smoothly and precisely) between a real-time motion mode and a relative positioning mode. Background technique [0004] In some prior art satellite navigation receivers are transitionable between a real-time kinematic (RTK) mode and a relative or precise positioning mode of position estimation. In order to operate in real-time motion mode, the receiver requires locally available real-time motion signals, which can be encoded with real-time motion correction data. If the real-time motion signal is interrupted, corrupted or lost, the ...
