Interference robustness

mosaic-X5TM features Septentrio's AIM+ technology, the most advanced on-board interference mitigation technology on the market. It can suppress the widest variety of interferers, from simple continuous narrowband signals to the most complex wideband and pulsed jammers. The radiofrequency (RF) spectrum can be viewed in real-time in both time and frequency domains.

Ultra-low power design

mosaic-X5TM provides RTK positioning at the lowest power consumption of any comparable device on the market.


mosaic-X5TM comes with fully-documented interfaces, commands and data messages. The included RxTools software allows receiver configuration, monitoring as well as data logging and analysis.

Intuitive web user interface

The mosaic-X5 includes an intuitive web user interface for easy operation and monitoring allowing you to control the receiver from any mobile device or computer. The web interface also uses easy-to-read quality indicators ideal to monitor the receiver operation during the job at hand.
