mosaic X5



Septentrio mosaic-X5™ is a multi-constellation receiver  packaged in a low-power surface mount module.  With a wide array of interfaces, mosaic-X5™ has been  specifically designed for the needs of mass market  applications like robotics and autonomous systems.  This high-reliability receiver tracks all Global Navigation  Satellite System (GNSS) constellations and supports all  current and future signals. With Septentrio’s unique  AIM+ technology for interference mitigation included,  Septentrio is now offering a performance benchmark  in mass market GNSS positioning.


* Small size, big performance

* All-in-view satellite tracking: multi-constellation, multi-frequency

* Best-in-class RTK performance

* AIM+ unique interference monitoring and mitigation  technology

* Industry-leading ultra-low power consumption

* Easy-to-integrate


No performance compromises

Sized at only 31 x 31 x 4 mm / 1.22 x 1.22 x 0.16 inches and weighing  only 7 g, mosaic-X5™ offers unmatched size to performance ratio. mosaic-X5™ includes:

* High update rate (>100 Hz) and low latency, both crucial for  control systems of autonomous applications

* Reliable centimetre-level positioning

* Full L2 support via P(Y) code

Designed for automated assembly

The  mosaic-X5™ module is designed for high volume automated  assembly lines with minimal amount of additional components  required. All interfaces, commands and data messages are fully  documented. The RxTools software suite allows convenient  receiver configuration, monitoring, data logging and analysis.  Offline processing is easy via our GeoTagZ software and its SDK  library for PPK (Post Processed Kinematic).

Advanced technologies inside

Septentrio’s GNSS+ toolset enables accuracy and reliability in the  toughest conditions, allowing you to complete projects with high  quality and efficiency. It includes:

* AIM+ the most advanced on-board interference mitigation  technology on the market (narrow and wide band, chirp  jammers).

* LOCK+ for robust tracking during high vibrations and  shocks.

* APME+ multipath mitigation to disentangle direct signal and  those reflected from nearby structures.

* IONO+ provides advanced protection against ionospheric  disturbances.
