The M56 GNSS RTK Box Receiver — powered by Septentrio Mosaic X5 — is an all-satellite all-frequency, multi-purpose compact RTK positioning and heading solution engineered for the widest possible range of precision GNSS applications. With support for GPS L1C/A/L1C/L1PY/L2C/L2P/L5, BeiDou B1I/B1C/B2a/B2I/B2b/B3I, GLONASS L1CA/L2CA/L2P/L3 CDMA, Galileo E1/E5a/E5b/E5 AltBOC/E6, NavIC L5, QZSS L1C/A/L1C/B/L2C/L5, and SBAS — the M56 covers every current GNSS constellation and frequency in a single 60-gram module that fits in the palm of your hand.
The M56’s performance foundation is Septentrio Mosaic X5’s processing architecture with more than 2 million active correlators — enabling simultaneous deep correlation across 448 hardware channels for the longest coherent integration time and most robust satellite signal tracking available in any compact GNSS receiver. This correlator density directly translates to better positioning performance in challenging signal environments: stronger acquisition of weak signals, more robust carrier phase tracking through interference and ionospheric scintillation, faster RTK initialization, and more reliable fix maintenance during high-dynamics UAV flight and vehicle maneuvers.
RTK horizontal accuracy of 0.6cm + 0.5ppm and vertical accuracy of 1cm + 1ppm, combined with 100Hz positioning and observation update rates and ultra-low latency under 10ms, make the M56 suitable for the most demanding real-time positioning applications — from centimeter-precision UAV photogrammetry and precision agriculture pass-to-pass guidance to intelligent robot navigation and high-frequency vehicle dynamics logging. Available in both single-antenna and dual-antenna configurations, the M56 provides directional output for applications requiring compass-free heading without magnetic sensor dependency.
Built on Septentrio’s proven signal integrity platform — AIM+ active interference monitoring and suppression, IONO+ ionospheric scintillation suppression, APME+ multipath mitigation, LOCK+ anti-shock and vibration tracking robustness, and RAIM+ receiver autonomous integrity monitoring — with OSNMA Galileo anti-spoofing authentication — the M56 maintains reliable centimeter-level RTK positioning through the most challenging electromagnetic and dynamic environments that UAV, agricultural, robotics, and logistics platforms encounter in daily operation.
The unique dual working mode architecture allows the M56 to operate as either a positioning receiver (rover) or a mobile base station — enabling self-contained RTK network deployment in field locations without CORS infrastructure, and providing maximum operational flexibility for precision agriculture, survey, and autonomous system applications across diverse geographic and connectivity environments.

Anti-Interference Technology Suite
AIM+ (Active Interference Monitoring & Suppression)
Detects and suppresses broadband, narrowband, and swept jamming signals in real time. Integrated interference indicator, mitigation engine, and spectrum measurement functions maintain reliable centimeter-level RTK positioning even in severely contested RF environments — urban UAV corridors, industrial automation facilities, and precision agriculture fields near high-power transmitters. AIM+ is Septentrio’s flagship real-time RF protection technology, proven across aerospace, defense, and precision agriculture deployments worldwide.
IONO+ (Ionospheric Scintillation Suppression)
Advanced protection against ionospheric interference — particularly outstanding in complex environments including equatorial regions, polar deployments, and periods of elevated solar activity. IONO+ maintains carrier phase tracking stability and RTK fix continuity in conditions that cause signal degradation and positioning loss on standard receivers, ensuring the M56 delivers reliable performance through the most challenging ionospheric events encountered in global precision positioning deployments.
APME+ (Advanced Phase Multipath Estimation)
Septentrio’s patented multipath suppression algorithm separates direct GNSS signals from reflected signals caused by buildings, vehicles, terrain, and infrastructure. Essential for UAV operations in urban environments, precision agriculture near farm structures, robot navigation in industrial facilities, and surveying in complex terrain — APME+ provides cleaner carrier phase measurements and better ambiguity resolution for all connected RTK applications.
LOCK+ (Excellent Tracking, Seismic and Shock Robustness)
Delivers superior signal tracking robustness through high-frequency vibration and mechanical shocks — specifically validated for UAV motor vibration, agricultural machinery engine vibration, robot actuator shock, and vehicle drivetrain loads. LOCK+ maintains continuous satellite lock through the high-dynamics maneuvers and vibration profiles of all M56 target platform categories, preventing the signal interruptions and re-initialization events that compromise positioning continuity.
RAIM+ (Receiver Autonomous Integrity Monitoring)
Continuously validates the integrity of GNSS positioning solutions in real time. Automatically detects and excludes faulty satellite signals without operator intervention — critical for personnel protection applications, intelligent logistics routing, autonomous robot navigation, and any application where undetected positioning errors have safety or operational consequences. RAIM+ provides the positioning integrity assurance required by professional-grade precision control and protection applications.
OSNMA (Open Service Navigation Message Authentication)
Hardware-level verification of Galileo navigation message authenticity — detecting and rejecting spoofed GNSS signals in real time. Provides security assurance for precision agriculture systems operating valuable autonomous equipment, intelligent logistics platforms, and personnel protection applications where deliberate GNSS signal manipulation poses an operational risk.
