GNSS surveying using RTK engine verification
First Claim
1. A method for determining a position of a GNSS receiver, the method comprising:
- determining whether a plurality of position measurements from a plurality of real-time kinematic (RTK) engines are within a first threshold distance from previously determined positions, from the plurality of RTK engines;
in accordance with a determination that the plurality of position measurements are not within the first threshold distance;
resetting one or more of the plurality of RTK engines;
after resetting one or more of the plurality of RTK engines, determining a plurality of additional position measurements using the plurality of RTK engines;
determining the position of the GNSS receiver based on the plurality of additional position measurements and the previously determined positions; and
in accordance with a determination that the plurality of position measurements are within the first threshold distance;
determining the position of the GNSS receiver based on the plurality of position measurements and the plurality of previously determined positions.

Abstract
Systems and methods for performing land surveying using real-time kinematic (RTK) engine verification are provided. In one example, a first set of positions of a GNSS receiver may be determined using each of a plurality of RTK engines. If a number of the plurality of RTK engines that produce a fixed solution is greater than or equal to a threshold value, a position of the GNSS receiver may be determined based on at least a portion of the first set of positions. The determined position may then be stored. This process may be repeated any number of times to produce a desired number of stored positions. In response to the number of stored positions being equal to a minimum value, a final position of the GNSS device may be determined based on the stored positions.
