Approximate latitude and longitude (in minute) work sufficiently.
Using a disabled satellite may deteriorate the accuracy. The disabled satellite
whose number has been input cannot be used for measurement.
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 7-41. The number for
Japan is 02.
Enter the height from the sea surface to the antenna.
Since the antenna height is constant in the case of a ship, 2D (2 dimensional)
measurement is more stable.
In order to use accurate measurement results only, select "UP to 10" or "UP to
5".
Select "LONG" to reduce the position deviation, which delays the response.
Select "SHORT" to improve the response, which increases the deviation.
