Abstract
Statistical studies of telemetry errors were made on data from the Solar Mesosphere Explorer Satellite. An examination of frame sync words within the data stream, as received at the ground station, indicated a wide spread of bit error rates among stations. A study of the distribution of errors per station pass revealed a tendency for the station software to add an even number of spurious errors to the court. Ground station reporting of observed errors was found to fall into one of three major types of error distributions discovered. A detailed examination of instrument science data, using a fourth-order wild point algorithm rejecting dropouts and other system errors, yielded on average a random bit error rate of 3.1x10 6 with 99% confidence limits of (2.63.8) X10 ~ 6. The system errors were typically found to be from 5 to 100 times more frequent than the identified random errors.
