102 SPSx51 Modular GPS Receivers User Guide
6. The antenna type, antenna height and measurement method used in the
previous setup of this base station are applied.
C
CAUTION – If the antenna height is different to the previous setup, then you must enter
the corrected height for the antenna (using the keypad and display) before starting
measurements. Failure to achieve the correct antenna height position for the antenna
results in errors in heights in subsequent measurements.
7. The receiver begins sending RTK CMR+ messages.
8. The RTK corrections begin streaming on the radio or Lemo port in the
application file.
Scenario Four: Repeat visit to a site with AutoBase Warning turned on
The following actions occur when you repeat a base station setup on a point, and the
AutoBase Warning is turned on:
1. The receiver is powered on.
2. The receiver begins tracking satellites.
3. The receiver determines the current position.
4. The receiver reviews the base station positions stored in the receiver.
5. The receiver finds a base station position that corresponds to the current
position.
C
CAUTION – If there are two or more base positions within a 50 meter radius of your
current position, the receiver will make the most recently created base position file active.
6. Since a base station position is found, the AutoBase warning does not appear.
7. The receiver loads the previous base information.
8. The antenna type, antenna height, and measurement method used in the
previous setup of this base station are applied.
C
CAUTION – If the antenna height is different from the previous setup, then you must
enter the corrected height for the antenna (using the keypad and display) before starting
measurements. Failure to achieve the correct antenna height position for the antenna
results in errors in heights in subsequent measurements.
9. The receiver begins generating RTK CMR+ corrections.
10. The RTK corrections begin streaming on the radio or port defined in the
previous setup of this base station.
Note – AutoBase recalls base station positions that are stored in the receiver. If the receiver
has been previously set up on a control point but the stored base station position is not
found in the receiver, it is possible that the information may have accidently been deleted.
In this case, use the display and keypad or the SCS900 system to manually set up the base
