If the receiver is not (for some reason) receiving differential corrections or if none of the
ports has been configured to receive differential corrections, the field LQ will either be empty or it
will look like this: 100%(999,0000,0000). Currently the values for this field are obtained from the [MS]
message.
• Receiver time shows the receiver’s current
time within day
. This value is taken
from the message [~~]. For more information about [~~], see the GRIL Reference
Manual.
Currently the message [~~] reports the
time within day
in the GPS time scale
only.
• Receiver date shows the receiver’s current date as specified in the corresponding
[RD] message.
• Clock offset describes the time derivative of (T
r
– T
rr
), where T
r
designates the re-
ceiver time, T
rr
designates the receiver reference time. For more information about T
r
and T
rr
, see the GRIL Reference Manual. This parameter is obtained from the [DO]
message and is expressed in parts per million (ppm).
• Osc. offset is derived from the message [OO] and it is expressed in ppm. The pa-
rameter describes the difference between the VCO’s nominal and quiescent frequen-
cies.
• Tracking time is the time elapsed since the last
complete
loss-of-lock event in the
receiver’s C/A channels as specified in the corresponding [TT] message.
