Before Installation
It is recommended that the instrument is installed so that it is
protected from mechanical influences and lightning
•
within 70 m of the antenna, without the need to use inline amplifiers.
•
•
located sufficiently far enough away from potential sources of radio fre-
quency interference. High-power signals from nearby radio, radar or GSM/
GPRS/UMTS cell towers can cause problems with GNSS tracking. Such inter-
ference is not harmful to the instrument but could cause a loss of GNSS
data.
For inside assembly, the instrument can be installed in any direction
•
When installing the instrument outside, orientate the instrument vertically
•
so that the connector points are pointing downwards
Ensure that the cables between the instrument and antenna are positioned to
prevent them from becoming bent, stretched or squeezed. For the installation
of the cables, the general rules for the installation of electrical wiring apply.
Please consider that a well-planned and thoroughly carried out electric installa-
tion not only protects the cables against damage, but also looks professional.
For detailed installation information, refer to the "GNSS Reference Station and
Networks - An Introductory Guide".
When using the wireless slot in device port with any slot in radio/GSM/3G/
CDMA module it is recommended to use an antenna extension cable and
mounting bracket to correctly position the antenna vertically, and away from
the Bluetooth/WLAN antenna, as shown in the following installation options.
Installation Options
GR Series instruments are designed for various installation cases. Below is a
short description of four installation cases for the instrument. Please note that
the diagrams do not show all the equipment required for a complete reference
station installation. For full installation details, please refer to the
