CAUTION – When you perform a future setup at the same location, the receiver assumes
that there has been no change to either the antenna height or the antenna height
measurement method used previously. It is therefore essential that you keep the antenna
height constant between setups.
If there is any risk that the antenna height might have changed, you must use the SCS900
Site Controller software to start (and so reset) the SPS880 Extreme Smart GPS antenna.
From the SCS900 Site Controller software, select Start Base Station.
8. The receiver begins generating RTK CMR+ corrections.
9. The RTK corrections begin streaming on the radio or port defined in the
previous setup of this base station.
Scenario Three: The stored base station position seems to be missing
• You set up the base station receiver on a point that you have previously used as
a base station, as in Scenario Two. But for some reason, the stored base station
position is not found in the receiver. Someone has inadvertently deleted the
data, or perhaps a different receiver ( for example, the other receiver in a pair)
was used on the previous occasion.
1. The base station receiver is set up on a point that you have previously used as a
base station.
2. The receiver is powered on.
3. The receiver begins tracking satellites.
4. The receiver determines the current position.
5. The receiver reviews the base station positions stored in the receiver.
6. The receiver does not find any base station that corresponds to the current
position.
7. The receiver will not begin transmitting RTK corrections and the radio LED will
not flash.
No RTK corrections will be streamed until you do one of the following things:
• Use the SCS900 Site Controller software to set up the base station.
• Change to the receiver that was previously used as the base station at this
location.
