Operator's Manual

GPS6 - DGPS STATUS

There are several windows in this display, the left hand windows are
divided into control and configuration windows. The right hand
window displays all the corrections that are being received. Shown
below is the GPS6 screen.
Status will tell you whether the correction data is being decoded is
error free or not. Normally, Status will indicate either DGPS mode
Off, DGPS OK, Tracking or Searching (Automatic search mode) or
No Lock (Manual tuning mode). DGPS OK indicates that RTCM
SC-104 DGPS corrections are being received without errors within
the Age Limit set in CFG1 DGPS. These information originates from
the MX421B beacon receiver. Searching indicates that the beacon
receiver is searching for the appropriate frequency and/or modula-
tion of the beacon transmitter in automatic search mode. No lock
indicates that the beacon receiver is not receiving DGPS corrections
from the selected station in manual tuning mode. You might see the
label Tracking, which indicates that a MSK beacon signal is present
but DGPS corrections are not being received. This is usually caused
by high noise on the beacon receiver or external device.
If you press the EDIT key, you can select between Automatic beacon
search mode, Manual beacon tuning mode, or Off. When the receiver
is in the Manual tuning mode, you can use the cursor key to scroll
down into the large window below Station Selection and edit the
Reference Station name. The name you enter will always be associ-
ated with the frequency to which you programmed the receiver. If
you move to another region that uses a frequency and name you pre-
viously entered, the receiver will display the previously entered name.
You can enter a new name for any manually tuned frequency at any
time.
