AutoBase Feature 7
Antenna type
The selected antenna type determines which options are available for determining the
antenna height. The AutoBase feature uses an antenna type of “R8 Model 2/SPS880
Internal.”
Scenarios
These scenarios describe what you may experience when using AutoBase technology.
Note – The AutoBase Warning feature is always turned on in an SPS781, SPS880 Extreme,
or SPS881 Extreme Smart GPS antenna.
Scenario One: Base station setup on first visit to a site
• You set up the base station receiver on a point that you have not previously used
as a base station with that receiver.
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 positions stored in the receiver.
5. The receiver does not find any base station that corresponds to the current
position.
6. The receiver will not begin transmitting RTK corrections and the radio LED will
not flash.
No RTK corrections will be streamed until the base station is set up using the SCS900
Site Controller software.
Scenario Two: Base station setup on a repeat visit to that site
• You set up the base station receiver on a point that you have previously used as
a base station with that receiver.
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. A base station position is found, so the AutoBase warning is not
displayed.
6. The receiver loads the previous base information.
