Method of determining location of machine

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.
