Septentrio is a company specialising in the development of high-precision GNSS receivers, based in Belgium. The company is known worldwide for its innovative technology and high quality products. septentrio's mosaic-X5 receiver is one of its flagship products and represents the company's latest technological achievement in the field of high-precision positioning.

The mosaic-X5 is a high-performance GNSS receiver designed for applications requiring centimetre-level accuracy. This receiver supports multi-band and multi-constellation tracking and is capable of providing survey-grade RTK positioning. It is designed with reliability in harsh environments in mind, including urban canyons, under forest canopies, and other environments where GNSS signals are limited. mosaic-X5 incorporates Septentrio's exclusive AIM+ technology, which mitigates a wide range of interference, including continuous narrow-band signals and complex wide-band and pulsed interferences, to ensure positioning accuracy and integrity.

The mosaic-X5's low power consumption makes it ideal for portable and mobile devices such as drones and handhelds. Its small size and light weight also make it ideal for space-constrained applications. In addition, the mosaic-X5 features advanced anti-jamming and anti-spoofing features that operate at an update rate of 100 Hz, ensuring the security and reliability of positioning data.

TERIA, in order to improve its service level in the surveying and GIS market, decided to develop a high precision positioning device with integrated L-band functionality. They chose Septentrio's mosaic-X5 receiver, a device that not only provides survey-grade RTK positioning capabilities, but also multipath recovery and anti-jamming and anti-spoofing technology to ensure a high level of security. mosaic-X5 is a low-power, multi-band, multi-constellation GNSS receiver that tracks all Global Navigation Satellite System (GNSS) The mosaic-X5 is a low-power, multi-band, multi-constellation GNSS receiver that tracks all Global Navigation Satellite System (GNSS) satellite signals and features Septentrio's AIM+ technology, an advanced on-board interference mitigation technology that suppresses a wide range of interference.

RTK (Real-time Dynamic Differential Positioning) technology, a real-time dynamic positioning technology based on carrier phase observations, is capable of providing centimetre-level positioning accuracy.RTK technology consists of a reference station, a mobile station, and a data chain.The reference station sends observation data and station coordinate information to the mobile station via the data chain, and the mobile station combines its own collected GNSS observation data for real-time processing to achieve centimetre-level The mobile station processes the GNSS observation data collected by itself in real time to achieve centimetre-level positioning accuracy.

The PYX device is designed with a variety of usage scenarios in mind, including as an RTK base or rover, a handheld device, or even integrated into a UAV. It is capable of receiving signals from full navigation satellite systems with an update rate of up to 100 Hz, ensuring real-time and accurate positioning. In addition, the PYX outperforms similar products in harsh GNSS conditions, under forest canopies and in urban canyons, offering more RTK positioning opportunities.

The TERIA network was launched in 2005 by the Association of French Surveyors to provide the surveying industry with real-time geo-positioning tools with centimetre-level accuracy to meet the demand for geo-referencing for terrain production. Since then, TERIA has continued to develop new services to meet the needs of the geolocation industry.

Overall, TERIA's PYX device is a high-performance positioning solution that combines advanced RTK technology and GNSS reception capabilities for a wide range of surveying and GIS application scenarios.
