Once the first operational Galileo satellites are available, a software update will be
required.

The GX1230+ GNSS, GX1220+ GNSS, and GRX1200+ GNSS receivers are addi­tionally designed to support Compass. The Compass signal definition is not fully
finalized, although, test signals have been tracked in a test environment. As changes
may still occur, Leica Geosystems cannot guarantee full Compass compatibility.

The GX1230+ GNSS, GX1230+, GX1220+ GNSS, GX1220+, GX1200+ with
PPS/Event option and GRX1200+ Series receivers use the GPS P-code signal,
which by U.S. policy is liable to be switched off without notice. Phase measurements

on L2 are ensured as these receivers automatically switch to patented tracking tech­niques.

Software upload All instrument software is stored in the System RAM of the receiver. The software

can be uploaded onto the receiver using the following methods:

• Using LGO the software is transferred via the serial interface to the Compact­Flash card in the receiver, which is then stored to the System RAM.

• By connecting the CompactFlash card directly to the computer either via an
internal card slot housing or an external OMNI drive, the software is trans­ferred to the card, which is then stored to the System RAM.

Description of the System GPS1200+ 17

A suite of optional survey-specific application programs are
available for the instrument.

Some of the programs are activated freely and require no license
key and others require purchasing and are only activated with a
license key.

1.2.2 Data Storage and Data Conversio n Co nc e pt

Description Data is stored within a job in a database on a memory device. This is either a

CompactFlash card or an internal memory.

18GPS1200+

Memory device

)

CompactFlash card: A CompactFlash card slot is standard. A CompactFlash

card can be inserted and removed. Various capacities are
available.

)

Internal memory: An internal memory is optional. It resides inside the

receiver. Available capacity: 256 MB or 1 GB

Unplugging connecting cables or removing the CompactFlash card during the meas­urement may cause loss of data. Always return to GPS1200+ Main Menu before
removing the CompactFlash card and switch off the instrument before removing
cables.

Whilst other CompactFlash cards may be used,
Leica recommends to only use Leica Compact­Flash cards and is not responsible for data loss
or any other error that may occur whilst using a
non-Leica card.

)

Data conversion Export

For GRX1200+ Series 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 export format
is defined in Format Manager which is a PC tool in LEICA Geo Office. Refer to the
online help of LGO for information on creating format files.

Data can also be exported from a job in DXF or LandXML format.

Import

Data can be imported from ASCII, DXF, GSI8 or GSI16 format.

Transfer raw data
to LGO

3.2 Battery

38GPS1200+

)

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.

Change battery

The batteries are inserted in the front of the receiver.

Operation GPS1200+ 59

Successful GNSS 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.

4.1 Overview

Description The GRX1200+ Series

• are designed to operate for specific reference station applications using remote
control software, for example LEICA GNSS Spider reference station software.

• support internal logging of raw observations which can be downloaded using an
external remote control software package such as LEICA GNSS Spider.

• support streaming output of GPS and GLONASS 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 to transmit data for real-time operations in proprietary as well as
standard RTCM, CMR and CMR+ formats, using a variety of communication
devices, including suitable radios, digital cellular phones or modems. The
GRX1200+ Series cannot receive reference station broadcasts and therefore
cannot be used as a real-time rover receiver.

• can be configured via a web interface.

Lightning conduc­tors

Suggestion for design of a lightning conductor for a GNSS 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 GNSS 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.
