GS50 / GS50+-4.0.0en Preface
The Leica Geosystems GIS DataPRO system is com-
posed of both hardware and software components.
1. Introduction
The hardware consists of the GS50 /GS50+ sensor, TR500
terminal and antenna. This is used in the field to collect
and record spatial (position) and non-spatial attributes.
After the data is collected in the field, the GIS DataPRO
office software allows you to import, edit and export the
data to your GIS. The software can also be used to design
codelists which allow you to customize the field data
collection process to suit your needs. To learn more
about the GIS DataPRO office software, please consult
the "Getting Started with the GIS DataPRO Office Soft-
ware User Manual".

2. System Description
The GS50 /GS50+ sensor consists
of both ahandheld terminal (TR500),
and the GPS receiver itself. The
GPS receiver receives the GPS
signal from the NAVSTAR satellites
and calculates a range to the satel-
lites that are visible.
The GS50 is a 12-channel L1 code
and phase GPS receiver. Phase
measurements are used internally to
smooth pseudorange measurements
for higher code positioning.
The GS50+ is a 12-channel L1, 12-
channel L2 code and phase GPS
receiver. The standard GS50+
records L1/L2 code and phase
measurements for post processing
and RTK purposes.
Data can be stored for post process-
ing in Ski-Pro or GISDataPRO.
Baselines can be calculated with a
precision of 5-10mm +/-2 ppm.
2.1 GS50 / GS50+ Sensor
With a radio modem the receiver can
be used for RTK measurements.
Coordinates can be calculated with a
precision of 1cm.
There are several Antennas avail-
able:
GS50:
• AT501 tracks L1 only
• RTB/RTS Combined Antennas
track L1 and RTCM Differential
signals.
GS50+:
• AT502 Dual frequency antenna
• AT 503 Dual Frequency Coke Ring
Antenna
• AT504 JPL Design Dual Frequency
Choke Ring Antenna
Please see section 5 for technical
specifications.

GS50 / GS50+-4.0.0en System Description
GPS Receiver
The TR500 terminal fits either directly on the receiver or can be connected to the terminal port using a cable.
A radio modem or an RTB module can also be fitted directly to the receiver. Alternatively, if the housing is not being
used, the radio modem can be connected to Port 1 or Port 2 using a cable. The GS50+ has an additional Port (Port 3
at the upper left side of the front plate ) that can be used also for Power/data in/out put.
The antenna is connected to the receiver via the ANT Port.
External power can be connected via a cable through the power port (PWR) or Port 2.

System Description GS50 / GS50+-4.0.0en
Terminal (TR500)
Use the CONFIG key to enter the
Configuration menus at any time.
The CE key is used to clear the last
character entered when entering
names, numbers, etc. into the
receiver.
Use the ENTER key to confirm an
entry into the system.
Use the STATUS key to access
status information at any time.
Use the Cursor keys to move around
the screen.
The keys F7-F10 are user definable
function keys. They can be defined
to execute commands or access any
screen of your choosing.
2.1 GS50 / GS50+ Sensor, contd.
The terminal keyboard is a QWERTY
layout designed for use in tempera-
ture extremes and also for gloved
hands if necessary.
The six keys F1-F6 at the top of the
keyboard correspond to the six
softkeys that appear on the screen
when the terminal is activated.
Pressing Shift followed by F1 will
always activate the Help screen.
Pressing F6 will quit the Help and
return you to the screen you were on.
Alternatively, pressing Shift followed
by F6 will quit the current application.
Use the Esc key to step back to the
previous screen at any time.
Use the Shift key when the Shift
symbol (⇑) is displayed to reveal
further choices on the softkeys F1-F6.
