22.7 Orbit Related Files<br />

The orbit related file types, explained in this section, are listed in Table 22.3.<br />

22.7.1 Satellite Broadcast Messages<br />

22.7 Orbit Related Files<br />

Type: ASCII<br />

Directory: Campaign-specific directory ORB.<br />

Extension: BRD<br />

Content: Satellite broadcast messages.<br />

Created by: Transformation programs (e.g., RXNBV3, ”Menu>RINEX>Import RINEX to <strong>Bernese</strong><br />

format>Navigation files”), BRDTST (”Menu>Orbits/EOP>Broadcast orbits>Check broadcast orbits”).<br />

Used by: BRDTST, BRDTAB, CODSPP, SATCLK, and BV3RXN.<br />

Example: Figure 22.19 and ${X}/DOC/EXAMPLE.BRD.<br />

The example file is truncated in the middle of the first message. The first record is a title line.<br />

Each message (containing 2·20 parameters: 20 for ephemerides and 20 for satellite clocks) is<br />

preceded by a record in which the satellite number and a sequence number for the messages<br />

of a satellite is contained. This sequence number is never used by the accessing programs,<br />

which means that different broadcast files may be merged into one file (by removing the<br />

title line of the following file). The values in the broadcast messages are explained in the<br />

header of the subroutine ${LG}/GTBRDC.f. A description of the message may also be found<br />

in [Dierendonck et al., 1978].<br />
