13. Firmware Configuration Data Block (CDB) CDB-ID 213 - PPS operating mode setting 1 Allow setting different operating modes for the PPS signal generation. Full operating mode setting is achievedusing both 213 and 214 parameters. This parameter includes different fields as reported in Table 208. Table 208. CDB-ID 213 Field Description Bits Values Description From B0 to 0 = on every second B3 1 = on even seconds 2 = on odd seconds PPS generation mode From B4 to 0 = UTC B7 1 = GPS_UTC (GPS Time) Reference time on which the PPS signal is synchronized. 2 = GLONASS_UTC (GLONASS Time) 3 = UTC_SU(1) 4 = GPS_UTC_FROM_GLONASS(2) From B8 to 1 = NO FIX B11 2 = 2D FIX 3 = 3D FIX GNSS fix condition for PPS signal generation. NO FIX: PPS signal is present even in GNSS NO fix conditions. 2D FIX: the PPS is present if the GNSS is at least in 2D fix condition. 3D FIX: the PPS is present only if the GNSS is in 3D fix conditions. From B16 0...24 to B23 Minimum number of satellites used for timing correction. PPS signal is generated if the number of satellites used for time correction is bigger the minimum number. This parameter should be set to 0 is the threshold is not used. From B24 0...90 to B31 Satellite elevation mask for time correction. It is the minimum satellite elevation angle to use the satellite for time correction. If this parameter is set to 0 there is no satellites filtering based on the elevation. (1) UTC(SU) is the Soviet Union UTC, it is derived from GLONASS time applying the UTC delta time downloaded fromGLONASS satellites. (2) GPS_UTC_FROM_GLONASS is the GPS time derived from GLONASS time applying the GPS delta time downloaded fromGLONASS satellites. If the software is configured to work in GLONASS only mode, UTC(SU) is identical to UTC and GPS_UTC_FROM_GLONASS is identical to GPS_UTC PNT-SG3FS GNSS Module Software User Guide 250
