    v17 v18  
    6161* GPS
    6262 * Old Style: 300 bits including the checksums
     63  * Inversed bits must be corrected, so the data can be directly read without taking care of this.
     64  * Carry bits from previous blocks must be corrected, so the parity of first block does not take any other non-zero bits into account.
     65  * Parity inside the 10 blocks need to take previous carry bits into account.
    6366 * CNAV-Style: 300 bits including the CRC
    6467* SBAS
    6568 * 250 bits including CRC
    6669* QZSS
    67  * 300 bits for GPS-compatible signals **Needs to be verified**
    68  * 250 bits for SBAS-compatible signal **Needs to be verified**
     70 * 300 bits for GPS-compatible signals
     71  * See GPS for specification
     72 * 250 bits for SBAS-compatible signal
