SSII Ephemeris

The receiver strips the parity bits. Each 30 bit word contains 24 databits and 6 parity bits. The receiver s/w has carried out consistency checks on the data, and all telemetry words, handover words and parity bits are stripped from the data (if not already stripped by the receiver). What remains is for each subframe 8 words with 24 bits, or 8 words with 3 bytes (1 byte = 8 bits), or 24 bytes per stripped subframe. At 24 bits per subframe times 8 words per subframe times 3 subframes = 576 bits
