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 culmi­nated 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 Navi­gator 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.

General Information

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 informa­tion concerning the use and interaction between Leica Geo Office and the SR20, please refer to the Leica Geo Office online help system.

Description of the 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 hand­held GPS receiver for professional data mapping.

Receiver Hardware

In most cases, a short introduction in the use of the Receiver will be provided by the local Leica Geosystems representative.

Charge the Batteries

Your Leica SR20 is powered by a rechargeable 7.2 V, Li­Ion 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.

Description of the System

Set Up the Equipment

For best performance, GPS data collection requires undis­turbed satellite signal reception. This means GPS Receivers work best in locations which are free of obstruc­tions.
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 online­help system for further details.
