Q Scenario One: Base station
setup on first visit to a site

base station position seems to
be missing
Q AutoBase process
The Trimble SPS781, SPS880 Extreme, and
SPS881 Extreme Smart GPS antennas feature
AutoBase
technology, which provides the
following advantages:
Reduced risk of a setup that uses incorrect
base station coordinates.
Reduced daily setup times for a mobile base
station. When you use an SPS781, SPS880
Extreme, or SPS881 Extreme Smart GPS
antenna as a base station receiver, you do
not need to reconfigure the receiver at the
start of each day.
The AutoBase feature is a function of the version
3.x receiver firmware, which supports both GPS
modernization (L2C and L5 signals) and
GLONASS signals. You cannot turn off the
AutoBase warning feature.
Note – With the SPS781, SPS880 Extreme, or
SPS881 Extreme Smart GPS antenna, always start
a base station setup by using the SCS900 Site
Controller software to initialize the SPS880 Extreme
Smart GPS antenna on a new point. See
page 62.
Please read this chapter even if you have used the
AutoBase feature in other Trimble receivers. New
functions now provide even greater benefits.
