This operation is for undertaking initial setting of GPS. The GPS receiver measures posi-
tion without initial setting but 10 or more minutes may be required after initial setting.

In the event high precision position determination is intended using DGPS, it is nec-
essary to set the beacon receiver.
: Approximate latitude and longitude is sufficient
When unhealth satellite is used, precision may deteriorate.
The satellite number input here is not used for measuring the
position.
: Japan is "02"
: Input the height of the antenna from the sea surface.
: Since the height of the antenna is fix in the case of an ocean
going vessel, greater stability in position is obtained in 2D (two
dimensions).
: If only position results with high precision are intended to be
used, designate 10 or less or 5 or less.
: When variance in position needs to be minimized, select
When response needs to be maximized select
with this latter setting, variance will increase.
