Figure 26: Age of DGPS/Sync screen
The Age screen shows the age of the differential data (in seconds) and the
time elapsed since the last valid differential correction received by the 8200HP
(Age of Sync). Because it takes some time to calculate differential corrections
at the reference station and broadcast these corrections to the 8200HP, the
smallest DGPS age will always be a few seconds.
Because the validity of a differential correction depends on the difference
between the time the differential signal is calculated and the time it is used by
the receiver, smaller values are better.
VBS Info
The VBS info screen consists of 7 different information screens, that can be
cycled through by pressing
repeatedly.
Figure 27: VBS Info screen: User Code
The User Code screen shows the receiver’s User Code, which is equal to the
last five digits of the serial number of the receiver.1+Usercode gives the
OmniSTAR serialnumber needed to activate the receiver. So 100208 in above
example.
Figure 28: VBS Info screen: User Enabled
The User Enabled screen shows whether or not the receiver is activated to
receive OmniSTAR differential corrections.
