mettatec X5 Multi-Band GNSS Receiver
With just a few seconds of setup, the X5 GNSS Receiver is one of the fastest
ways to take centimeter-grade measurements. By connecting your phone to the X5
over Bluetooth® or WiFi, you can setup and operate the X5 GNSS Receiver. The
X5 GNSS Receiver works with common GIS software including SW Maps, SurvPC,
Field Genius, and any GIS software that supports NMEA over Bluetooth.
This device can be used in three modes:
- GNSS Positioning also known as ‘Rover’
- GNSS Positioning with RTK (10 mm accuracy) also known as ‘Rover with RTK Fix’
- GNSS Positioning with NTRIP (10 mm accuracy) receives streaming correction data from a NTRIP caster to apply as real-time corrections to a GNSS receiver.
- GNSS Base Station

WORKING MODES
Rover Mode| Bluetooth is enabled under the name of X5 Receiver Rover-XXXX
where “XXXX” represents the device’s MAC
---|---
It can be used with the SW Maps App when the device outputs NMEA messages.
Max. recommended rate is 5Hz to avoid Bluetooth data collisions.
For PPK it is required to output RXM and TIM2 messages. Use “Logging defaults
for RINEX” in Configuration Mode.
Correct Data logging to the SD card starts when the logging and PPS Indicator
blink. They both are required for correct *.ubx data in order to get RINEX
data after processing.
If data logging was paused by entering Configuration Mode, it is resumed in
this mode.
Base Mode| Bluetooth is not enabled in this mode
RTK LED indicator will be always off
Datalogging to SD card is enabled
Configuration Mode| During this mode, datalogging to the SD card is paused. In
order to resume datalogging, push the mode selector button.
WiFi is available under the name of “Metta-X5” and can be Connected by using
the password “123456789”
| Can be used only with the Metta X5 App or accessing by using a web browser
with the IP address http://192.168.4.1
