Meteorological sensors
Meteorological sensors are used for measuring air pressure, temperature and relative humidity. The data from the
meteo sensor is logged together with the GPS raw observations into the MDB and RINEX files. If RINEX logging is
active, an additional meteo RINEX file is created that contains the data from the meteo sensor.
Data is logged into the same file as the GNSS raw observations (MDB) or into a file with the same file name but with
the extension m (RINEX). No data is logged, unless raw observation logging is configured and a logging session is
started.

Tilt sensors
Tilt devices (such as the Leica NIVEL210) are used for measuring inclinations. The data from the tilt device is logged
together with the GNSS raw observations into MDB files. When logging RINEX files, the tilt data is written into a
special auxiliary file.

Oscillators
An external oscillator can be used to provide a better quality time signal to the receiver than the receiver's own
internal clock. The same external oscillator can also be used with a number of receivers so that each receiver is
guaranteed to be tracking satellites using the same time signal. An external oscillator is attached to the receiver via
the port OSC.
Select
Internal
to use the receivers internal clock, or if an external oscillator is connected to the oscillator port, select
the type of external oscillator and the frequency.
The following oscillator types can be used with a GR10:
•
TCXO: A temperature compensated crystal oscillator (TCXO) is used.
•
OCXO: An oven controlled crystal oscillator (OCXO) is used.
•
Rubidium: A rubidium based external oscillator is used.
•
Cesium: A cesium based external oscillator is used.
The external oscillator can work with 5 MHz or 10 MHz.
