4.2.14 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, it may speed up the time to first fix 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
