A device for determining the location of a subject includes a positioning unit for generating each time period, t, position data corresponding to the location of the subject and motion data indicative of whether the subject is moving or stationary. There is a processor unit configured to, if the motion data indicates that the subject is moving at time period t, set the location of the subject at time period t to be the location corresponding to the position data. The processor unit is also configured to, if the motion data indicates that the subject is stationary at time period t, obtain from the positioning unit the position data for the next n time periods t; determine the average position of the subject over the n time periods t; and maintain as the location of the subject, the determined average position while the subject remains stationary.

1. A device configured to be disposed on a subject for determining the location of the subject, the device comprising: A positioning unit for generating each time period, t, position data corresponding to the location of the subject and motion data indicative of whether the subject is moving or stationary, wherein the motion data includes linear acceleration data regarding the subject;A processor unit, responsive to the position data and motion data, configured to: if the motion data indicates that the subject is moving at time period t, set the location of the subject at time period t to be the location corresponding to the position data; andif the motion data indicates that the subject is stationary at time period t, the processor unit is configured to: obtain from the positioning unit the position data for the next n time periods t;determine the average position of the subject over the n time periods t; andmaintain as the location of the subject, the determined average position while the subject remains stationary. 2. The device of claim 1 wherein the positioning unit includes a global navigation satellite system receiver in communication with a plurality of satellite constellations to produce the position data and speed over ground (SoG) data, wherein the positioning unit further includes an attitude and heading reference system configured to provide to the processor unit the linear acceleration data regarding the subject; and wherein the SoG data and the linear acceleration data comprise the motion data provided to the processor unit. 3. The device of claim 1 wherein when the SoG data indicates that the subject is moving and the linear acceleration data indicates that the subject is stationary, the processor unit determines that the subject is stationary and if the SoG data indicates that the subject is moving and the linear acceleration data indicates that the subject is moving the processor unit determines that the subject is moving. 4. The device of claim 2 wherein the attitude and heading reference system comprises one or more of a gyroscope, accelerometer, and a magnetometer. 5. The device of claim 1 wherein when the subject resumes motion after being stationary, after a predetermined delay, the processor is configured to set the location of the subject at each subsequent time period t to be the location corresponding to the position data until the subject is determined to be stationary. 6. The device of claim 1 wherein the subject is one of an animal, a human, or an object. 7. The device of claim 1 wherein the device is in the form of a collar. 8. A method for determining the location of a subject using a device disposed on the subject, the method comprising: generating each time period, t, position data corresponding to the location of the subject and motion data indicative of whether the subject is moving or stationary, wherein the motion data includes linear acceleration data regarding the subject;if the motion data indicates that the subject is moving at time period t, setting the location of the subject at time period t to be the location corresponding to the position data;if the motion data indicates that the subject is stationary at time period t, obtaining position data for the next n time periods t; determining the average position of the subject over the n time periods t; and maintaining as the location of the subject, the determined average position while the subject remains stationary. 9. The method of claim 8 wherein the step of generating includes using a global navigation satellite system receiver in communication with a plurality of satellite constellations to produce the position data and speed over ground (SoG) data, and using an attitude and heading reference system configured to provide to the processor unit the linear acceleration data regarding the subject; wherein the SoG data and the linear acceleration data comprise the motion data. 10. The method of claim 8 wherein when the SoG data indicates that the subject is moving and the linear acceleration data indicates that the subject is stationary, the subject is determined to be stationary and if the SoG data indicates that the subject is moving and the linear acceleration data indicates that the subject is moving the subject is determined to be moving. 11. The method of claim 9 wherein the attitude and heading reference system comprises one or more of a gyroscope, accelerometer, and a magnetometer. 12. The method of claim 8 wherein when the subject resumes motion after being stationary, after a predetermined delay, the location of the subject at each subsequent time period t is set to be the location corresponding to the position data until the subject is determined to be stationary. 13. The method of claim 8 wherein the subject is one of an animal, a human, or an object. 14. The method of claim 8 wherein the device is in the form of a collar.
