Receiving Status
8.5.4.1 GPS Initial Setting
Set the GPS receiver at the default values. Although GPS receiver starts measuring without setting the
default values, it may take more than 10 minutes to start receiving after installation.
• Items to be set
Own ship position: Approximate latitude and longitude (in minute) work sufficiently.
Exclusion satellite: Using a disabled satellite may deteriorate the accuracy. The disabled satellite
whose number has been input cannot be used for measurement.
Geodetic system: The own ship position and the coastal line may shift if the geodetic system in
the radar is different from that of the coastal line ROM card in use. Enter the
appropriate geodetic system number described on page 8-37. The number for
Japan is 02.
Antenna height: Enter the height from the sea surface to the antenna.
Fixed mode: Since the antenna height is constant in the case of a ship, 2D (2 dimensional)
measurement is more stable.
DOP level: In order to use accurate measurement results only, select "UP to 10" or "UP to
5".
Average position: Select "LONG" to reduce the position deviation, which delays the response.
Select "SHORT" to improve the response, which increases the deviation.
