GPS
If you are using a GPS with the SIR 30, select CUSTOM from the GPS Type and enter the location of the
GPS receiver antenna with respect to the GPR antenna connected to Channel 1. If the GPS antenna is
mounted to the Channel 1 GPR antenna, both the X and Y values will be zero (0). If the GPS antenna
location is behind the Channel 1 antenna location, the X value will be the distance of the GPS behind the
GPR antenna, and the number will be negative. The Y value determines how far to the right or left the GPS
is relative to the GPR antenna connected to Channel 1. If you are standing behind the antenna, facing in
the direction of your survey profile, this number will be positive if the GPS antenna location is to the left
of the GPR antenna and negative if the GPS antenna location is to the right of the GPR antenna.

The diagram at the top of the System Settings menu provides the User with a quick visual aid for
describing the GPR antenna position relative to the GPS antenna location (Figure 22). The GPS offset
positions (if any) are saved as the In-line (X) and Cross-Line (Y) offset values in the file header and are
used by RADAN 7 to correct the antenna offset positions for processing multi-channel files .
