ARINC BIT DESCRIPTION SETTING
10-9 Source/Destination Identifier Not Used = 00
Unit 1 = 01
Unit 2 = 10
Unit 3 = 11
8-1 Octal Label 060
Note 1: When a satellite is removed from the solution because it is below the C/No threshold or it is
isolated, bit 23 is set to zero (invalid).
Note 2: GPS SV PRN: 1-32; SBAS SV PRN: 38-56 for 120-138, Reserved SV PRN: 0, 33-37, 57-63.
Note 3: Only delta-range measurements are used. This bit is forced to 1.
Note 4: When the SBAS Range Offset APD Label ID Assignment is set to a non-zero value (label is
output) and the SBAS Range Offset conversion is compatible with SBAS PA mode, bit 20 is
set to 1; otherwise this bit is set to 0. This bit does not supersede bit 23. The setting of 0 when
the SBAS Range Offset APD Label ID Assignment is set to 0 corresponds to the legacy
encoding for a C/A code measurement.
Note 5: Only the GPS system is supported. This bit is forced to 0.
