Cassini Stellar Reference Unit: Performance Test Approach and Results

The Cassini Stellar Reference Unit (SRU) is the prime attitude determination sensor on the Cassini spacecraft...To ensure that the SRU will operate within specification for the entire mission, an extensive test program has been undertaken to characterize the SRU performance prior to launch and to quantify any expected performance degradation. Results from several eomplimentary test programs are presented and compared with pre-test performance predictions.

Cassini Tracking and Identification Architecture

The Cassini spacecraft will perform a detailed examination of the Saturnian system, including the release of a probe to study Saturn's largest satellite, Titan. The star tracker for the Cassini mission must provide accurate data during the entire flight including four years of measurement in a harsh radiation environment.
