Abstract: Modern multi sensor surveillance systems integrate several multispectral imaging channels, laser range finder and positioning sensors (digital magnetic compass – north finding sensor and GPS sensor). Sensor data fusion provides own position determination and also selected target position determination. Starting from CEP 50 error definition, multi sensor generalized structure, sensor accuracy, and basic measurement equitation derivation we analyzed target position error. It is shown that north finding sensor error has a critical influence on the target position error over whole system field of regard. This analysis contributes to sensor accuracy requirements definition.

Keywords: Surveillance systems, multi sensor systems, position determination, position determination error, CEP50.
