<p>The volume of messages generated by spaced based interceptors (SBI'S) resulting from a booster launch can lead to an unacceptably large total time for the messages to propagate through the system. In order to help relieve this problem, one might identify the SBI's with the highest quality estimates of the launch information. Message traffic can by sharply reduced if these SBI's can be identified, and message transmission restricted to their messages. Launch parameters and position are estimated using a template based tracking algorithm. A single measure of quality based on the estimated covariance matrix of the measured position is proposed and tested using simulation. Results describe possible modifications to the template based tracking algorithm that would reduce error and allow the quality of a message to be determined.
