Q Autobase Process
Autobase is a feature of the Trimble SPS GPS
receivers that enables you to reduce daily setup
time for mobile base stations and to reduce the
likelihood of using incorrect base station
coordinates during setup.
The Autobase feature allows you to set up the
SPS GPS receivers as a base station receiver and
save you time so you do not need to reconfigure
the receiver at the start of each day. It also allows
you to set up the base station on a new site
without needing to configure the settings in the
receiver.
If you have used the Autobase feature in other
Trimble receivers, Trimble recommends that you
read this chapter carefully because new functions
in this feature provide greater benefit to you.
<Rob. Comment from Alan: ìIt will also be
available in SPS880 but it operates a little
differently because the receiver has no display.

SPSx50 Modular GPS Receiver User Guide 95
8 Autobase Feature
Autobase Warning
The Autobase Warning, when enabled, prevents the receiver from creating a new base
station position and begin operating as an RTK base station when no previous base
station position exists that corresponds to the current position of the receiver.
When the Autobase Warning is on, the receiver will not begin transmitting RTK
corrections from a base position (latitude, longitude, and height) that is not a part of
the GPS site calibration. When the Autobase Warning is off, the receiver begins
transmitting RTK corrections from a new base position. You need only power on the
receiver the first time on a point, and you do not need to manually configure the base
station settings.
By default, the SPS GPS receivers have the Autobase Warning turned on. The receiver
uses the Autobase Warning setting to control how the receiver performs when
different criteria are met.You can turn the Autobase Warning on or off using the
keypad and display. For more information, see chapter 5 on how to access the System
Setup screens. <<cross-ref to do later>>
Working with Autobase
This section contains some example scenarios that you will experience. In each section
there is a step-by-step process that explains what you will experience in each scenerio.
Scenerio One: First visit to a site with Autobase Warning turned off
The following actions occur when you set up the base station for the first time on a
new point and the Autobase Warning is turned off:
1. The receiver is powered on.
2. The receiver begins tracking satellites.
3. The receiver determines the current position.
4. The receiver reviews the previous base station positions stored in the receiver.
5. The receiver does not find any base station that corresponds to the current
position.
6. The receiver creates a new base station location for the current location.
7. The receiver sets the antenna height to 0. The antenna height is measured to the
antenna phase center.
C
CAUTION – On each reoccupation of the point, you must ensure that the receiver
antenna is set up in exactly the same location and at exactly the same height. Trimble also
recommends that you use a T-bar or Fixed height tripod so that the position is easy to
re-establish. Failure to achieve the same height position for the antenna results in errors
in heights in subsequent measurements.
96 SPSx50 Modular GPS Receiver User Guide
Autobase Feature 8
Where you set up each time with potentially different antenna heights, Trimble
recommends that on the first setup after AutoBase has completed its process,
that you edit the antenna height (using the receiver keypad and display). The
updated antenna height changes the AutoBase setup, so that on subsequent
setups, when you again change the antenna height, you will get correct height
information during measurement. At the first setup, Trimble recommends that
you change the AutoBase setup and antenna height before you carry out a site
calibration.
8. The receiver begins generating RTK CMR+ corrections.
9. The RTK corrections begin streaming over the internal radio. If there is no
internal radio, the receiver defaults to streaming the corrections on the Lemo
port.
Scenerio Two: First visit to a site with Autobase Warning turned on
The following actions occur when you set up the base station for the first time 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 positions stored in the receiver.
5. The receiver does not find any base station that corresponds to the current
position.
6. The receiver displays a warning that Autobase has failed.
7. No RTK corrections will be streamed until the base station is set up using the
keypad and display or an SCS900 controller.
Scenerio Three: Repeat visit to a site with Autobase Warning turned off
The following actions occur when you repeat a base station setup on a point, and the
Autobase Warning is turned off:
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.
6. The receiver loads the previous base information.
SPSx50 Modular GPS Receiver User Guide 97
8 Autobase Feature
7. 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 height position for the antenna results in
errors in heights in subsequent measurements.
8. The receiver begins generating RTK CMR+ corrections.
9. The RTK corrections begin streaming on the radio or port defined in the
application file.
Scenerio 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.
6. Since a base station position is found, the Autobase warning is not displayed.
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.
CAUTION – If the antenna height is different to the previous setup, then you must enter
the corrected height for the antennae (using the keypad and display) before starting
measurements. Failure to achieve the correct 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 have been 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 inadvertently been
deleted. In this case, you should use the display and keypad or the SCS900 system to
manually set up the base station. Make sure that you use the same base latitude, longitude,
and height as in the previous setup. If the same base station latitude, longitude, and height
or a known control point is not used, you will experience position or height errors in all
subsequent measurements.
98 SPSx50 Modular GPS Receiver User Guide
Trimble recommends that after any new base station setup, or at the start of each
measurement session, that you measure a known point to verify that position and height
errors are within tolerance. This is good practice and it takes just a few seconds to
potentially eliminate gross errors typically associated with repeated daily setups of the
base station.

Default Settings 9
Postprocessed GPS data is typically used for control network measurement
applications and precise monitoring. GPS measurement data is collected over a period
of time at a static point or points, and then postprocessed to accurately compute
baseline information.
Logging data after a power loss
If power is unexpectedly lost while the receiver is logging data, the receiver tries—
when power is restored—to return to the state it was in immediately before the power
loss. The receiver does not reset itself to default settings.
If the receiver was logging data when power was lost, data logging is not resumed. To
resume data logging after a power loss, you need to complete the following steps:
1. Restart the receiver. When power is cycled on the receiver, the receiver will
power on with data logging off.
2. Use a web browser or the keypad and display to turn data logging back on.
