Abstract
Systems and methods for the determination and recording of positioning system compliance malfunctions for commercial motor vehicles (CMV). One method includes detecting and accumulating the fault time when positioning system information is invalid or unavailable. Additionally, when positioning system information is invalid or unavailable, the processor estimates an uncertainty distance that the vehicle has travelled since the last valid location. The system then determines and records positioning system malfunction based on positioning system fault events, the accumulated fault time, and the uncertainty distance. The system stores valid location information and data relating to the positioning system fault event on the base unit until the base unit is coupled to the portable device.
