9.2 Command Set 77
9.2.3 Status Mode Commands
Return Status of Event/Deviation
Command: SA, SB
SA and SB return the event/deviation channel setup information for channels A and B respectively,
read index number and write index number.
Response: D(E), R = nnn, S = mmm
C
Format: D indicates the input channel is in 1–PPS deviation mode
E indicates the input channel is in event mode
nnn = Channel read index (000 to 199)
mmm = Channel write index (000 to 199)
NOTE: When nnn = mmm, using the EA or EB command to read event data, the event buffer is
empty, i.e., all event data which has been recorded has also been read.
Return Clock Status
Command: SC
SC returns the current clock status.
Response: L/U, U=xx, S=nn
C
Format:
L = Clock currently locked to GPS (U for unlocked).
xx = Indicates loss of lock period, up to 99 minutes.
nn = User specified out-of-lock delay, 00 to 99 minutes (refer to Table A-8).
S = Off if the out-of-lock function is deactivated, S = ZDL indicates zero delay.
Receiver Status
Command: SR
SR returns the current receiver status.
Response: V=vv S=ss T=t P=Off E=0
C
Format: vv = number of satellites, visible to the antenna, per almanac.
ss = relative signal strength (range: 0 to 255, nominal value = 15)
t = number of satellites being actively tracked (up to twelve)
P = Off, indicates that the time dilution of precision (TDOP)
calculation is not being performed. Returns 1.0 99.0, depending
on satellite geometry, when TDOP calculation is being performed.
A TDOP calculation is NOT performed if less than 3 satellites are
visible, OR if Position-Hold is active. E = 0, currently unused.
