GNSS moving base positioning
First Claim
1. A method of determining a position of an antenna of a GNSS rover from observations of GNSS signals collected at the antenna over multiple epochs and from correction data for at least one of the epochs, comprising:
- determining a first-epoch rover position relative to a moving base location,determining a second-epoch update of the first-epoch rover position relative to the moving base location for a second epoch using a single-differenced delta phase process, andcombining the first-epoch position and the second-epoch update to obtain a second-epoch rover position relative to a moving base location of the second epoch.

Abstract
Methods and apparatus are presented for determining a position of an antenna of a GNSS rover from observations of GNSS signals collected at the antenna over multiple epochs and from correction data for at least one of the epochs. A first-epoch rover position relative to a moving base location is determined, a second-epoch update of the first-epoch rover position relative to the moving base location for a second epoch is determined using a single-differenced delta phase process, and the first-epoch position and the second-epoch update are combined to obtain a second-epoch rover position relative to a moving base location of the second epoch.

10. Apparatus for determining a position of an antenna of a GNSS rover from observations of GNSS signals collected at the antenna over multiple epochs and from correction data for at least one of the epochs, comprising at least one processor with instructions enabling the at least one processor to
determine a first-epoch rover position relative to a moving base, determine a second-epoch update of the first-epoch rover position relative to the moving base location for a second epoch using a single-differenced delta phase process, and combine the first-epoch position and the second-epoch update to obtain a second-epoch rover position relative to a moving base location of the second epoch.
