    Save configuration 6.4 Heading Configuration This command is used for dual-antenna receivers (UB482, UM482, and UM442). The heading result is the angle from True North to the baseline of the ANT1 to ANT2 in a clockwise direction. The heading function is enabled by default settings. See Figure 6- 1 Heading Schematic for the schematic.

    6.5 Heading2 Configuration The heading2 result is the angle from True North to the baseline of the base to rover in a clockwise direction. Dual-antenna heading receiver (UB482, UM482, UM442) supports heading2. The heading2 for the dual-antenna receiver is the angle from True North to the baseline of the base to ANT1 in a clockwise direction.
