1. General Information
For decades, Leica Geosystems has enjoyed a worldwide
technological lead in the manufacture of classical
surveying instruments and systems. Starting in 1987, Leica
Geosystems established a close business relationship with
Magnavox's commercial GPS business unit for the design
and construction of GPS surveying sensors. This culmi-
nated into Leica Geosystems acquisition of the Magnavox
GPS business unit in 1994. With this purchase, the
unbroken chain of impressive "firsts" now incorporated the
field of satellite navigation and positioning technology.
Magnavox was one of the first pioneers in this arena,
playing a leading role in the development of GPS and its
predecessors. Further acquisition of the Philips Ap Navi-
gator business in 1997 widened Leica Geosystems
product palette to an even greater extent.
Leica Geosystems offers an entire product basket of GPS
receivers. This includes receivers designed for Land
Surveying, GIS, Machine Control, Monitoring and various
other applications. The SR20 GPS receiver allows the user
the maximum in flexibility. The SR20 GPS receiver can be
used as a high accuracy Land Surveying device, a
powerful GIS data collector, or even a Reference Station.
The SR20 is packaged with the Leica Geo Office software.
This software is also extremely flexible with it’s ability to
accept data from a variety of Leica receivers including: total
stations, levels, and GPS.

The Leica SR20
The Leica SR20 GPS receiver was designed to provide the
Land Surveying community with a reliable, rugged and
accurate GPS receiver that is also flexible enough to fit
both sub-meter and centimeter accurate land surveying
requirements. The Leica SR20 represents a true turnkey
GPS solution by integrating the GPS receiver and antenna
within the chassis of a handheld data collector. You will find
the SR20 is extremely easy to use and yet has the all the
power you would expect out of a Leica GPS receiver.
Overview of the User Manual
The User Manual is intended to provide information
concerning setup, safety, storage and technical data of the
SR20 and accessories. For additional information on the
use and operation of the SR20, please refer the SR20
"Getting Started Guide" (provided separately). For informa-
tion concerning the use and interaction between Leica Geo
Office and the SR20, please refer to the Leica Geo Office
online help system.

GPS Receiver
The GPS Receiver receives the GPS signal from the
NAVSTAR satellites and calculates a range to all visible
satellites.
The Leica SR20 is a 12-channel L1 code and phase hand-
held GPS receiver for professional data mapping.
See section "
Technical Data ".
Receiver Hardware
In most cases, a short introduction in the use of the
Receiver will be provided by the local Leica Geosystems
representative.
Also refer to the SR20 "
Getting Started Guide."

LEICA SR20 User Manual-1.1.0en
Charge the Batteries
Your Leica SR20 is powered by a rechargeable 7.2 V, Li-
Ion battery.
The battery can be charged and discharged hundreds of
times but it will eventually wear out. When the operation
time is noticeably shorter than normal, it is time to buy a
new Leica Geosystems GEB90 Li-Ion Battery.
One battery, fully charged, will power the SR20 for about 7
hours continuously. Operating times will be shorter when
working in cold weather.
Primary use/charging
• The battery must be charged prior to using it for the first
time because it is delivered with an energy content as
low as possible.
• For new batteries or batteries that have been stored for
a long time (> three months), you should take the
battery through one complete charge/discharge cycle.
• For Li-Ion batteries, a single discharging and charging
cycle is sufficient. We recommend carrying out the
process when the battery capacity indicated on the
charger or on a Leica Geosystems product deviates
significantly from the actual battery capacity available.
• The permissible temperature range for charging is
between 0°C to +40°C/ +32°F to +104°F. For optimal
charging we recommend charging the batteries at a low
ambient temperature of +10°C to +20°C/+50°F to +68°F
if possible.
• It is normal for the battery to become warm during
charging. Using the chargers recommended by Leica
Geosystems, it is not possible to charge the battery if
the temperature is too high.
Operation/Discharging
• The batteries can be operated from -20°C to +55°C/
-4°F to +131°F.
• Low operating temperatures reduce the capacity that
can be drawn; very high operating temperatures reduce
the service life of the battery.

Set Up the Equipment
For best performance, GPS data collection requires undis-
turbed satellite signal reception. This means GPS
Receivers work best in locations which are free of obstruc-
tions.
Press and release the Power Button located on lower left
of the keyboard. The unit will reply with an audible tone,
then proceed to a splash screen and then to the Main
Menu.
Your Leica SR20 is now fully ready for operation.
Post-processing software
The Post-processing software is used to process the
observations taken by the Receiver in order to compute
baselines and coordinates.
Leica Geo Office software is the standard post-processing
software for the SR20 GPS receiver. Please refer to the
"Getting Started Guide" and the Leica Geo Office online-
help system for further details.
