Septentrio has built an industry-leading position in the three dimensions of anti-jamming resilience, multi-system compatibility and ionospheric suppression technology, which are analyzed below:
Septentrio GNSS receiver anti-jamming technology
Septentrio’s AIM+ technologies, such as adaptive trap filtering and broadband interference suppression units, provide multiple protection mechanisms against malicious/unintentional interference and spoofing signals. In the JammerTest test organized by the Norwegian government, its receivers maintained centimeter-level accuracy and trajectories even in the face of extreme interference several times the strength of GNSS signals, while competing receivers had positioning errors of hundreds of meters. This technology, combined with real-time spectrum analysis, dynamically identifies and filters interference sources in the Septentrio GNSS receiver, ensuring high positioning availability in complex electromagnetic environments, far surpassing competing products that rely on a single hardware solution.
Full-band multi-constellation compatibility: the cornerstone of Septentrio seamless global coverage
Septentrio GNSS receiver supports GPS, BeiDou, Galileo, GLONASS and other full constellation signals, covering L1/L2/L5/E5/E6 frequency bands. The multi-band redundancy design not only improves positioning accuracy, but also ensures continuity by automatically switching to the backup signal when some bands are interfered with, Septentrio Mosaic-H module solves the heading angle and pitch angle in real time through the dual-antenna fusion algorithm, which eliminates the need to rely on external sensors, and significantly reduces the complexity of the system integration. This design is especially suitable for dynamic scenarios such as high-speed maneuvering of UAVs and precision operation of agricultural machinery.
Septentrio IONO + Ionospheric Suppression Technology to Overcome Space Environment Challenges
In response to signal distortion caused by ionospheric scintillation, Septentrio’s IONO+ algorithm dynamically eliminates affected satellite signals through real-time monitoring of the amplitude scintillation index and phase scintillation index. Measurements show that during periods of strong ionospheric activity, the altitude error of receivers equipped with IONO+ is controlled within 10 cm, while the error of traditional solutions can reach several meters. This technology, combined with Septentrio’s APME+ multipath suppression and RAIM+ integrity monitoring, creates a multi-layered protection to ensure positioning stability at high latitudes or during periods of peak solar activity.The lightweight design and ultra-low power consumption of Septentrio Mosaic-H module are suitable for SWaP-sensitive scenarios such as drones and self-driving robots.
Septentrio systematically overcomes the core challenges in the field of high-precision positioning with its three core technologies: AIM+ anti-interference, full-band redundancy, and IONO+ ionospheric suppression. In the complex electromagnetic environment, AIM+ technology dynamically suppresses multiple GNSS signal interferences through RF optimization and adaptive algorithms to ensure centimeter-level accuracy without offset; full-band multi-constellation support provides redundant signal switching capability to ensure continuous global positioning from the equator to the poles; in the face of ionospheric interference, IONO+ algorithm monitors scintillation index in real time, and in the area of strong ionospheric activity, the altitude error can be controlled within 10 cm, which is higher than traditional positioning. In the face of ionospheric interference, the IONO+ algorithm monitors the scintillation index in real time, and in areas of strong ionospheric activity, the altitude error can be controlled within 10 centimeters, which is higher than the traditional solution. The three technologies work together to form a closed loop of anti-interference, global coverage and space protection.
