The Role of High-Precision Positioning and Anti-Jamming Technology in Modern Firefighting
In modern fire rescue operations, the complexity, danger, and uncertainty of fire scenes place extremely high demands on rescue efficiency and accuracy. Traditional ground reconnaissance is plagued by pain points such as limited visibility, hazardous environments, and delayed data. Firefighting UAVs equipped with high-precision positioning and anti-jamming technology have emerged as key equipment to break through the bottlenecks in rescue operations.
The Significant Advantages of the Septentrio mosaic-G5 P3/P3H GNSS Receiver Module
Endowed with the advantages of “centimeter-level positioning, full-scenario anti-jamming, and ultra-low power consumption for long endurance,” the Septentrio mosaic-G5 P3/P3H GNSS Receiver Module injects “precision DNA” into firefighting UAVs. It upgrades them from simple aerial observation tools to core fire rescue platforms integrating precise reconnaissance, real-time positioning, and efficient collaboration, fully covering the entire process including fire monitoring, rescue command, and post-disaster assessment. Among them, the mosaic-G5 P3H further features the capability of heading & pitch angle measurement or heading & roll angle measurement, providing stronger support for UAV autonomous navigation.
Full-Scenario Anti-Jamming and Stable Signals: Adaptable to Complex Fireground Environments
Leveraging Septentrio’s proprietary GNSS+ Technology Suite, firefighting UAVs can seamlessly tackle complex fire rescue environments:
AIM+ Advanced Anti-Jamming Technology: Features interference and spoofing detection with automatic mitigation capabilities. It resists electromagnetic disturbances and communication equipment interference in fire scenes, ensuring uninterrupted positioning signals.
APME+ Multipath Mitigation Technology: Eliminates signal interference caused by reflections from buildings and smoke, enhancing positioning accuracy in complex indoor and outdoor scenarios.
LOCK+ Technology: Maintains stable signal tracking amid strong vibrations, shocks, and severe wind turbulence at fire scenes, guaranteeing the reliability of UAV flight and data transmission.
IONO+ Technology: Provides advanced ionospheric disturbance protection, further improving positioning stability under complex meteorological conditions.
Centimeter-Level Positioning + Rapid Initialization: Precisely Anchor Critical Targets
After equipping firefighting UAVs with the mosaic-G5 P3/P3H receiver, they can achieve RTK high-precision positioning with horizontal accuracy of 0.6 cm + 0.5 ppm and vertical accuracy of 1 cm + 1 ppm, along with rapid initialization in just 7 seconds. This enables precise capture of the latitude, longitude, and altitude coordinates of key fire zones, trapped personnel, and flammable/explosive hazard sources, providing data support for rescue plan formulation and avoiding rescue delays caused by positioning deviations or excessively long initialization times.
Military-Grade Ruggedness: Withstanding Extreme Fireground Environments
The mosaic-G5 P3/P3H receiver boasts a wide operating temperature range of -40℃ to +85℃ and complies with the MIL-STD-810H shock and vibration resistance standard. It can withstand high temperatures, smoke corrosion, and shock/vibration during rescue operations in fire scenes, while maintaining stable operation in a humidity range of 5% – 95% (non-condensing). This ensures continuous and reliable performance even in extreme firefighting scenarios.
Efficient Operation & Ultra-Low Power Consumption with Long Endurance Guarantee
A high update rate of 20 Hz and latency below 10 ms ensure that firefighting UAVs transmit real-time dynamic fire scene data even during high-speed flight, while synchronously marking the fire spread trajectory.
Boasting an industry-leading ultra-low power consumption design (P3 model: typical 0.44 W, maximum 0.57 W; P3H dual-antenna model: typical 0.6 W, maximum 0.785 W) and a lightweight body (only 2.2 g), the module significantly extends UAV endurance. This meets the long-duration operation requirements for large-area fire patrols and multi-point fire monitoring.
Multi-Constellation & Multi-Band Reception: Full-Scenario Signal Coverage
Equipped with 789 hardware channels, the receiver can simultaneously track multi-band satellite signals from five major constellations: GPS, GLONASS, Beidou, Galileo, and QZSS. Even in signal-complex areas such as urban high-rise-obstructed zones or mountain canyons, it maintains stable signal reception, ensuring uninterrupted firefighting operations.
A Powerful Enabler for Post-Disaster Reconstruction Planning and Hidden Hazard Rectification
In post-disaster reconstruction planning and hidden hazard rectification, its outstanding positioning accuracy provides high-precision support, enhancing the scientific nature and efficiency of reconstruction work.
Significant Investment Value for the Future
Choosing the mosaic-G5 P3/P3H is a valuable insurance for fire safety, equipping research teams with cutting-edge detection technology and safety assurance solutions for all personnel.
