Patent number: 11879982Abstract: Methods for determining corrected positions of a global navigation satellite system (GNSS) rover using a GNSS base station and one or more GNSS reference stations include determining a statistical representation of position measurements from the GNSS reference stations and an instantaneous position measurement from the GNSS reference stations. A position correction is determined based on the statistical representation and the instantaneous position measurement. A corrected position of the GNSS rover is determined based on a position of the GNSS rover and the position correction.Type: GrantFiled: January 6, 2021Date of Patent: January 23, 2024Assignee: Trimble Inc.Inventors: Michael Cash, Stuart Riley, Vivek Nadkarni

Patent number: 8295411Abstract: Embodiments of the present technology recite a method and system for maintaining integrity of a binary offset carrier (BOC) signal. In one embodiment, a first correlator is configured for multiplying a timing signal with an internally generated pseudo-random noise (PRN) signal to create a reference signal. The first correlator is further configured for combining the reference signal with a received PRN signal and outputting a first correlation function based upon the combining. A second correlator is configured for multiplying the internally generated PRN signal with the received PRN signal and for outputting an integrity correlation function. A comparison component is configured for determining the offset of the reference signal relative to the received PRN signal based upon a comparison of the integrity correlation function with the first correlation function.Type: GrantFiled: February 20, 2009Date of Patent: October 23, 2012Assignee: Trimble Navigation LimitedInventor: Stuart Riley
