ECSS Communications — Error Detection (space-systems/ecss/e50-error-detection)

Compute the error detection a space data transfer protocol owes under ECSS-E-ST-50C clause 5.6.13.4, whose three normative items ask that the link protocol detect errors at all, that the project set its own figure for the units the code lets through undetected, and — a recommendation, not a requirement — that the detection chosen suit the telemetry and telecommand performance of clause 5.6.11. Header coverage is not among the three and is graded here as this leaf's own discipline. Derive the corruption rate a channel bit error rate produces over a unit, the fraction that escapes a checksum or a CRC, the undetected units expected across a pass, and the weakest catalogue co…
