2.4.1 Software Concept
Description All receivers use the same software concept. The software is divided into standard
and customised application programs.
Standard software
components
Customised application programs
Languages
Description of the System GPS1200 2-10
System software: To manage and configure data and functions.
Includes the application program Survey to
measure.
Application program software: To generate data in specific application programs.
Some application programs are already uploaded
when purchasing the receiver. Some application
programs can be uploaded through LGO. Some
application programs have to be purchased and
then activated through a specific licence key.
Customised application programs can be developed locally using the GeoC++
development environment. Information on the GeoC++ development environment is
available on request from the Leica Geosystems representative.
Number of languages: Three languages can be stored on the receiver at one
time - English and two others. English cannot be
deleted. One language is selected as active language.
Description of the System
Validity of a language: • For standard software: If a language is not available
Uploading software Software can be uploaded
• from LGO on a PC through a serial interface to the CompactFlash card in the
receiver and from there to the System RAM.
• from a CompactFlash card to the System RAM.
•from Leica GPS Spider using the firmware upload tool through the available
communication link, for example a serial, dial-up modem or network connection.
2-11GPS1200
for the system software, the English language is
used instead. Application programs run in the
language they where loaded.
• Customised application programs do always run in
the language they were developed in.

Data conversion Export
For GRX1200/GRX1200 Pro receivers:
While in remote operation mode, stop point occupation and ring buffer logging before
removing the CompactFlash card.
Data can be exported from a job in a wide range of ASCII formats. The format is
defined in Leica Geo Office. Refer to the online help of LGO for information on
creating format files.
Import
Data can be imported from ASCII, GSI8 or GSI16 format.
2-13GPS1200
Transfer raw data
to LGO
)
Raw data can be transferred between the database on the CompactFlash card or
the internal memory of the receiver and LGO in two ways:
• From the CompactFlash card or the internal memory directly through a serial
interface to a project in LGO on a PC.
• From the CompactFlash card using for example an OMNI drive as supplied by
Leica Geosystems to a project in LGO on a PC.
CompactFlash cards can directly be used in an OMNI drive as supplied by Leica
Geosystems. Other PC card drives may require an adaptor.
2.4.3 Power
General Use the Leica Geosystems batteries, chargers and accessories or accessories
recommended by Leica Geosystems to ensure the correct functionality of the instrument.

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), it is effectual to make only one 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.

Steady antenna for
static surveys
Centred and
levelled antenna
Operation GPS1200 4-22
Successful GPS surveys require undisturbed satellite signal reception, especially at
the receiver which serves as a reference. Set up the receivers in locations which are
free of obstructions such as trees, buildings or mountains.
For static surveys, the antenna must be kept perfectly steady throughout the whole
occupation of a point. Put the antenna on a tripod or pillar.
Centre and level the antenna precisely over the marker.

Description The GRX1200/GRX1200 Pro
• are designed to operate for specific reference station applications using remote
control software, for example Leica GPS Spider reference station software.
• support internal logging of raw observations which can be downloaded using an
external remote control software package such as Leica GPS Spider.
• support streaming output of GPS raw observations and status information.
• can log or stream out data from specific external devices approved by Leica
Geosystems, such as meteo and tilt, which can be directly output to an external
remote control software package.
• can be used - with a suitable radio, digital cellular phone or modem attached - to
transmit data for real-time operations using proprietary as well as standard
RTCM, CMR and CMR+ formats. The GRX1200 and GRX1200 Pro cannot
receive reference station broadcasts and therefore cannot be used as a realtime rover receiver.
• operate in the same manner as the other GPS1200 receivers.
• have the same receiver and measurement performance as the other GPS1200
receivers. Refer to "8 Technical Data" for information on technical data.

Behaviour when
turning off and on
Behaviour after
power failure
Turning the GRX1200/GRX1200 Pro off and on again resets the receiver. The
consequences are:
• If the configuration of the output is stored in the configuration set, standard
NMEA messages are still output.
• All data/message outputs scheduled via OWI or LB 2 commands are no longer
output.
• Data logging parameters and interface configuration options, that have been set
by OWI or LB 2 commands and have not been saved to a configuration set using
the corresponding OWI or LB 2 command, are reset.
After temporary power failure, the GRX1200/GRX1200 Pro will automatically power
itself up and resume the previously set operations. Two power fail recovery options
are available - Sudden Loss Only and Always. To access the configuration select

• If the product has to be permanently mounted in an exposed location, it is advisable to provide a lightning conductor system. A suggestion on how to design a
lightning conductor for the product is given below. Always follow the regulations
in force in your country with regard to grounding antennas and masts. These
installations must be carried out by an authorised specialist.
• To prevent damages due to indirect lightning strikes (voltage spikes) cables, for
example for antenna, power source or modem should be protected with appropriate protection elements, like a lightning arrestor. These installations must be
carried out by an authorized specialist.
• If there is a risk of a thunderstorm, or if the equipment is to remain unused and
unattended for a long period, protect your product additionally by unplugging all
systems components and disconnecting all connecting cables and supply
cables, for example, receiver - antenna.
Lightning conductors
Suggestion for design of a lightning conductor for a GPS system:
1. On non-metallic structures
Protection by air terminals is recommended. An air terminal is a pointed solid or
tubular rod of conducting material with proper mounting and connection to a
conductor. The position of four air terminals should be uniformly distributed
around the antenna at a distance equal to the height of the air terminal.
The air terminal diameter should be 12 mm for copper or 15 mm for aluminium.
The height of the air terminals should be 25 cm to 50 cm. All air terminals should
be connected to the down conductors. The diameter of the air terminal should
be kept to a minimum to reduce GPS signal shading.
2. On metallic structures
Protection is as described for non-metallic structures, but the air terminals can
be connected directly to the conducting structure without the need for down
conductors.
