VP ONCORE COMMAND REFERENCE

Back to Index

LATITUDE (@@Ad)

Three parameters (latitude, longitude, and height) are used to establish

the initial position of the VP receiver. The initial position estimate

provides the VP with a starting point to begin the satellite acquisition

process. It is not necessary for the user to initialize the coordinates with

a position estimate, however the TTFF will be minimized by providing an

estimate that is close (within one degree is sufficient) to the user's

position.

Latitude is measured in degrees north (+) or degrees south (-) of the

earth's equator. The default datum for the latitude is WGS-84, however

this may be changed by the user with the Datum Select (@@Ao

command). This input command sets the initial latitude coordinate only if

the VP is not yet computing a position fix, or is used to replace the

current latitude with a new latitude while in Position Fix mode.

Range: -90º (South Pole) .. +90º (North Pole)

Default value: 0º (Equator)

Units: milliarcseconds (mas) (1º = 3,600,000 mas)
