FAST GNSS RECEIVER CONVERGENCE BY RELATIVE POSITIONING

摘要

A method of implementing fast GNSS convergence by relative positioning is disclosed. A GNSS receiver which is coupled with a mobile machine is shut down. The GNSS receiver is in a converged state at shut down. A movement sensor is monitored to determine if net movement of a GNSS antenna coupled with the mobile machine exceeds a threshold net movement parameter while the GNSS receiver is shut down. Upon power up of the GNSS receiver, a shorter convergence algorithm is initiated in response to determining that the threshold net movement parameter has not been exceeded. The shorter convergence algorithm is also initiated upon power up of the GNSS receiver in response to determining that the threshold net movement parameter has been exceeded but information from the movement sensor has been used to update the location of the GNSS receiver since said shut down.

1. A method of implementing fast GNSS convergence by relative positioning, said method comprising:
shutting down a GNSS receiver which is coupled with a mobile machine, wherein said GNSS receiver is in a converged state at shut down; monitoring a movement sensor to determine if net movement of a GNSS antenna coupled with said mobile machine exceeds a threshold net movement parameter while said GNSS receiver is shut down; and upon power up of said GNSS receiver,
initiating a shorter convergence algorithm in response to determining that said threshold net movement parameter has not been exceeded; andinitiating said shorter convergence algorithm in response to determining that said threshold net movement parameter has been exceeded but information from said movement sensor has been used to update the location of said GNSS receiver since said shut down.
