Abstract
Official abstract text for this publication.
A method of determining a location of a machine is provided. The method includes determining a location of the machine based on the signals received from an IMU at each of a plurality of unit time. The method also includes determining a location of the machine corresponding to a first unit time based on signals received from the satellite positioning unit at a second unit time. The method includes determining an error associated with the location of the machine, by a processing unit, based on the location determined by the satellite positioning unit and the location determined based on the signals received from the IMU at a unit time successive to the first unit time. The method also includes adding the error to the location of the machine determined based on the signals received from the IMU at a successive unit time to the second unit time.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of determining a location of a machine, the method comprising: receiving signals from an Inertial Measurement Unit (IMU) at each of a plurality of unit time; determining a location of the machine based on the signals received from the IMU; triggering a satellite positioning unit of the machine at a first unit time; determining a location of the machine corresponding to the first unit time based on signals received from the satellite positioning unit at a second unit time; determining an error associated with the location of the machine, by a processing unit, based on the location determined by the satellite positioning unit and the location determined based on the signals received from the IMU at a unit time successive to the first unit time; and adding the error to the location of the machine determined based on the signals received from the IMU at a successive unit time to the second unit time.
