Elevation mask
A receiver typically has a higher elevation mask and it will not use any satellite below the elev
ation angle of its set mask. The recommended setting is to set the elevation mask of GSG to a
value equal or less than that of the device under test.
In order to conserve channels by not generating signals the GNSS receiver will not use in its
fix, the elevation mask in the GSG can be set to a slightly higher value. This is especially import
ant with, e.g., GSG-52/53 Series units, or GSG-5 models equipped with 4-channels.
3.5.9 Advanced Configuration Options
3.5.9.1 Multipath Signals
A multipath signal is a GNSS signal bouncing off a reflective surface prior to reaching the
GNSS receiver antenna. Quite likely, this causes many of the same signals to arrive at the
receiver at different times. The receiver then needs to determine which of the signals are
received directly.
