Safety Instructions
For detailed Safety Instructions regarding handling, installation, operation and storage of the Trimble MX50 system, refer to the Trimble MX50 User Guide.
Acclimatisation
The Trimble MX50 system incorporates sensitive electronics and optical
components.
Due to variation in temperature and air pressure during airfreight
transportation, rapid increase of temperature after unpacking may cause
condensation of water inside the main components of the Trimble MX50 system.
Water inside component housings can cause short circuits and can damage the
instrument when switched on.
Therefore, after air freight transportation, allow a period of 24 hours for
acclimatisation in a place with constant temperature and air pressure before
switching on the Trimble MX50 system.
Important! It is absolutely mandatory that the user sets the country code
of the Wi-Fi module of the MX50 system correctly before first usage.
Connect with your operation device (Laptop, tablet) either via LAN cable or
Wi-Fi to the MX50 system.

Operation, Prerequisites to System Setup and Operation.
Initializing GNSS/IMU
After start of a mission:
-
POS data (GNSS/IMU) is being recorded automatically once enough satellites are visible and a RT-position is available (blue trajectory on map window gets visible – the real-time navigation solution is available).
-
Drive to an open sky environment for more than 30 seconds while changing direction and speed. NAV status button should change color from red to orange!
For optimisation of trajectory postprocessing use the following field procedure (after Nav status button got orange!): -
Stop vehicle in open sky area PDOP of 3.0 (or better).
-
Stand still for a minimum of at least 3 minutes (the system is automatically collecting static
GNSS data in the background). -
Drive for more than 30 seconds while changing direction and speed, NAV status button should change color from orange to green now! / IMU alignment is complete when the NAV status button switches to green.
-
Now you can start collecting your mission data …
Data Capturing
