Abstract
A method for determining the presence of interference on a GPS receiver is described. The method involves monitoring global positioning system data received by a receiver under known non-interfering conditions, storing the data for analysis and, at a later time, comparing the data, over a period of time, with the position output of a pure inertial navigation system to determine the presence of characteristics indicating interference.
