2.2.2 Power Concept
Use the batteries, chargers and accessories recommended by Leica Geosys-
tems to ensure the correct functionality of the instrument.
Power for the instrument can be supplied either internally or externally.
Model Power supply
Internally One battery (GEB331) ts into the instrument.
Externally GEB371 battery connected via a cable, or
Car battery connected via a converter cable supplied by Leica
Geosystems, or
10.5 V‑28 V DC power supply via a converter cable supplied
by Leica Geosystems, or
110 V/240 V AC to 12 V DC power supply unit, supplied by
Leica Geosystems.
For permanent operations use Uninterruptible Power Supply units as a back-
up in a main power failure.
2.2.3 Data Storage Concept
Data (Leica GNSS raw data and RINEX data) can be recorded on the internal
memory or on the SD card.
Internal
memory:
The GS18 GNSS instrument has an internal memory.
Available capacity: Up to 4 GB
SD card: The GS18 GNSS instrument has an SD card slot tted as stand-
ard. An SD card can be inserted and removed.

☞
While other SD cards can be used, Leica Geosystems recommends
to only use Leica industrial grade SD cards and is not responsible
for data loss or any other error that can occur while using a
non-Leica card.
Unplugging connecting cables, removing the data storage device or interrupt-
ing the power supply during the measurement can cause loss of data. Only
remove the data storage device, unplug connecting cables or interrupt the
power supply when the GS GNSS instrument is switched off.
