Abstract	An integrity checking system (ICS) for satellite telemetry is described. The integrity of satellite telemetry is defined in terms of relevance, correctness, completeness, and confidence. The relevance factor provides the basis for partitioning the telemetry data set into relevant and irrelevant data for current processing needs. This in turn enables a satellite monitoring system to vary the amount of data according to the load on the system. The correctness factor deals with the accuracy as well as the timeliness of telemetry data. The detection error conditions in satellite system control originate from analysis of telemetry. The completeness factor in assessing the integrity of telemetry data makes it possible to choose a representative set of available data for analysis. This factor takes precedence over the relevance factor whenever a satellite exhibits anomalous behavior such as uncontrollable spin, or component failures. The confidence factor determines the data sampling rate. That is, in normal satellite monitoring, the sampling rate may be longer than in a crisis situation where more data may be needed for error correction.
