The Navigation Challenge of Communication Drones
In critical mission areas such as emergency communications, aerial relay, and mobile network coverage, communication drones play an irreplaceable role. Their flight stability and positioning accuracy directly determine the quality and reliability of communication links. However, traditional GNSS receivers often struggle in densely built-up urban environments and airspaces saturated with electromagnetic interference. Signal blockage and multipath reflections from buildings cause positioning drift, while interference from communication equipment and malicious spoofing attacks may lead to signal loss or trajectory deviation. These risks can disrupt continuous communication transmission and jeopardize mission safety.
Centimeter-Level RTK Positioning for Stable Aerial Relay
The Septentrio mosaic-X5 GNSS receiver addresses these challenges by delivering professional-grade GNSS performance in an ultra-compact 31 × 31 × 4 mm form factor weighing only 7 grams. With 448 hardware channels, it simultaneously tracks signals from GPS, GLONASS, BeiDou, and Galileo, ensuring strong signal availability and redundancy in urban canyons.
The receiver achieves exceptional RTK performance, offering horizontal accuracy of 0.6 cm + 0.5 ppm and vertical accuracy of 1 cm + 1 ppm. RTK initialization completes in just 7 seconds, while update rates of up to 100 Hz and latency below 10 milliseconds provide near-real-time positioning feedback. This precision enables communication drones to maintain stable hovering, accurate point-holding, and consistent flight paths—directly improving the reliability of airborne communication links.
Advanced Anti-Jamming and Anti-Spoofing Protection
AIM+ Advanced Anti-Interference Technology
The integrated AIM+ technology continuously monitors the RF spectrum and actively suppresses narrowband, broadband, and swept-frequency interference. This creates a robust electronic defense against unintentional interference and deliberate spoofing attempts, ensuring navigation continuity during critical communication missions.
GNSS+ Technology Suite for Complex Environments
APME+ multipath suppression filters reflected signals from buildings and terrain, preserving positioning purity in dense urban areas.
LOCK+ anti-vibration technology maintains stable signal tracking during turbulence, strong winds, and emergency maneuvers.
IONO+ ionospheric mitigation compensates for ionospheric disturbances caused by space weather and diurnal variation.
Together, these technologies form a deeply integrated protection system that enables uninterrupted navigation for communication drones operating as airborne network nodes.
Low Power Consumption and High System Integration
Beyond accuracy and robustness, the Septentrio mosaic-X5 GNSS receiver is optimized for endurance-critical communication missions. With typical power consumption of just 0.6 W and a maximum of 1.1 W, it significantly extends drone flight time during prolonged relay or standby operations.
The receiver supports multiple interfaces, including four high-speed UARTs, Ethernet, USB 2.0, and SDIO, enabling seamless integration with flight controllers, communication payloads, and onboard processors. Open protocols and comprehensive documentation allow rapid development, while the RxTools software suite simplifies configuration, monitoring, and data analysis.
