4.12 LOCATION
The command,
LOC
, is for reading or setting the current location of the receiver. This
command displays the current latitude and longitude calculated by the GPS receiver.
During initial installation, time to first fix may be decreased if the user inputs an
approximate position using this command. The GPS receiver constantly calculates its
position based on the satellites it is receiving. Once the unit has acquired its first fix,
entering a new position using this command has no effect. Also, after initial installation
the receiver will keep its current position in Non-Volatile RAM so that on subsequent
power cycles the unit will reach first fix much faster than at initial installation.
To view the current receiver location, issue the
LOC
command as shown below:
Type:
LOC <ent>
Example Response:
CURRENT LOCATION:LATITUDE = N 43 07 00.407 LONGITUDE = W 077 29 13.442
To enter a new location place the clock in
Set Mode
and issue the
LOC
command as
follows:
Type:
LOC [N:S] [DD MM SS.SSS][E:W] [
DDD MM SS.SSS
] <ent>
Where:
N
= North Latitude
S
= South Latitude
DD MM SS.SSS
= Latitude Degrees:Minutes:Seconds
E
= East Longitude
W
= West Longitude
DD MM SS.SSS
= Longitude Degrees:Minutes:Seconds
