A method and apparatus for processing signals from a sensor system including a distributed Kalman filter utilizing distributed data processing techniques to determine various system states (e.g. position, velocity, attitude, etc.). System state processor (18) and sensor state processors (24, 26, 28) are in communication with each other and receive and calculate error state data. The system errors are fed back to the sensor device processor and both the system and instrument errors are fed back to a data collection processor to continually make corrections in the measurements to compensate for the error estimation. |
