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 an instrument:
• 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.

Leica surveying controllers CS10/CS15
The CS10 and CS15 controllers can be used to configure a GR/GM receiver. The following step-by-step guide explains how to access
the web interface of a GR/GM receiver using a CS10 or CS15.
