Abstract

Official abstract text for this publication.

A method for Real Time Kinematic satellite positioning includes receiving navigation satellite carrier signals, receiving phase correction signals from a reference station, calculating a set of integer phase ambiguities from double-differenced measurements of pseudo-range and phase, and calculating a relative position of the mobile receiver from the set of integer phase ambiguities and the double-differenced measurements of pseudo-range and phase.

First claim

Opening claim text (preview).

We claim: 1 . A method for Real Time Kinematic satellite positioning comprising: at a mobile receiver, receiving a first navigation satellite carrier signal from a first navigation satellite, receiving a second navigation satellite carrier signal from a second navigation satellite, receiving a third navigation satellite carrier signal from a third navigation satellite, and receiving a fourth navigation satellite carrier signal from a fourth navigation satellite; at the mobile receiver, receiving first, second, third, and fourth phase correction signals from a reference station; at the mobile receiver, calculating a set of integer phase ambiguities from double-differenced measurements of pseudo-range and phase; and at the mobile receiver, calculating a position of the mobile receiver from the set of integer phase ambiguities and the double-differenced measurements of pseudo-range and phase.
