Abstract : This report summarizes the results of two studies conducted to address specific issues related to the utility of a specific high resolution multispectral sensor, designated the F sensor. The first study assessed the validity of a sensor model, entitled the Performance Prediction Model (PPM), which was provided by the sensor contractor. This was performed by cross checking results with an independent sensor model. In most cases, good agreement was achieved. The second study assessed the expected performance of a vital component of the F sensor, a magnetic bearing system (MBS) for line of sight control and stabilization.
