Practical application of multi-sensor fusion is critically dependent on the sensor system's registration in both time and space. A UK MOD study involving both Government agencies and industry has explored the practical issues of the field deployment of radar and EO (IRST) sensors and the subsequent fusion of their output data at both the track and plot level. The program used commercially available GPS units as the time and position sensor on both radar and EO sensors. The same system was used to record target position. The paper will use the data collected during the practical field trials to illustrate the impact of time and positional errors on the fusion process.
