9.2 Command Set 79
Response: nnnnn.nn
C
(from -1000.00 to +18000.00 meters WGS-84)
Return Latitude
Command: LA
LA returns the current antenna latitude. In Position Hold mode, LA returns the current position-
hold latitude setting. In Fix mode, LA returns the most recent computed latitude value (calculated
each second).
Response: Ndd:mm:ss.sss
C
Format: N = North (S for South)
dd = degrees
mm = minutes
ss.sss = seconds (fractional seconds)
Return Longitude
Command: LO
LO returns the current antenna longitude. In Position Hold mode, LO returns the current position-
hold longitude setting. In Fix mode, LO returns the most recent computed longitude value (calcu-
lated each second).
Response: Wddd:mm:ss.sss
C
Format: W = West (E for East)
ddd = degrees
mm = minutes
ss.sss = seconds (fractional seconds)
Position–Hold – OFF
Command: PH0
PH0 deactivates the Position–Hold timing mode. The receiver resumes computing time and position
solutions approximately each second. This is referred to as the Fix mode.
Response:
C
Position–Hold – ON
Command: PH1
PH1 activates the Position–Hold timing mode. In this mode, the receiver position is held fixed
and each channel is used to compute a timing solution. These solutions are averaged together,
resulting in reduced timing noise due to to Selective Availability and RF channel noise. To operate
