Up sampling reference station data
First Claim
1. A method of determining a position of a GNSS device, the method comprising:
- receiving GNSS signals at the GNSS device from a plurality of GNSS satellites;
generating, at the GNSS device, GNSS raw data based on the GNSS signals;
storing the GNSS raw data on the GNSS device;
receiving first correction data and second correction data,wherein the first correction data corresponds to a first time,wherein the second correction data corresponds to a second time later than the first time, andwherein the first correction data and the second correction data are generated from data from at least one reference station;
interpolating the first correction data and the second correction data to produce third correction data, wherein the third correction data corresponds to a time of the GNSS signals;
determining position data for the GNSS device based on the third correction data and the GNSS raw data.

Abstract
A method of determining a position of a GNSS device includes receiving GNSS signals at the GNSS device from a plurality of GNSS satellites. The GNSS device generates GNSS raw data based on the GNSS signals. The GNSS raw data is stored on the GNSS device. The GNSS device receives first correction data and second correction data. The first correction data and the second correction data are generated from data from at least one reference station. Third correction data is determined based on the first correction data, the second correction data, and the GNSS raw data. Position data for the GNSS device is determined based on the third correction data and the GNSS raw data.
