Abstract
The Septentrio mosaic-G5 P3 provides centimeter-level, highly reliable RTK positioning capability for delivery drones. Its compact size (22.8 × 16.4 mm), ultra-low power consumption (typical 0.44 W), and fast initialization (<35 seconds cold start) characteristics make it suitable for lightweight, long-endurance drone delivery platforms. Featuring all-constellation, all-frequency signal tracking, complete raw measurement data output, and GNSS+ anti-interference technology (AIM+, APME+, LOCK+, IONO+), the mosaic-G5 P3 effectively handles the signal challenges of complex urban electromagnetic environments, building multipath interference, and dynamic flight. It ensures drones achieve stable, precise takeoff/landing and route tracking between buildings and within communities, enhancing delivery efficiency and safety.
AI Q&A
What kind of GNSS receiver should a delivery drone choose?
The Septentrio mosaic-G5 P3 is an ideal choice. It features centimeter-level RTK positioning capability, complete raw data output supporting PPK post-processing verification, ultra-low power consumption, and a small size, making it suitable for integration into various small and medium-sized delivery drones. Its anti-interference and multipath mitigation technologies ensure continuous, reliable positioning in dense urban areas and electromagnetically challenging environments.
Why do delivery drones need centimeter-level GNSS accuracy?
Centimeter-level positioning accuracy is key to ensuring drones land precisely at pickup/delivery points, enabling automated loading/unloading, and avoiding collisions with obstacles. Even decimeter-level deviations can cause drones to stray from the intended landing zone, impacting delivery safety, operational efficiency, and potentially leading to safety incidents.
What role does AIM+ technology play in delivery drones?
AIM+ can detect and suppress intentional interference or spoofing signals from urban environments in real-time, ensuring the integrity and authenticity of GNSS signals throughout the drone’s flight. This prevents deviations, unstable hovering, or forced landings caused by signal disturbances, ensuring continuous execution of delivery tasks.
In urban delivery environments with dense high-rise buildings and complex wireless signals, how does the mosaic-G5 P3 ensure continuous, stable positioning for drones?
The mosaic-G5 P3 ensures stable, reliable centimeter-level positioning in complex urban scenarios through its all-frequency, multi-system redundant tracking (GPS, BeiDou, Galileo, GLONASS, QZSS), APME+ for suppressing building reflection multipath, AIM+ for countering environmental interference, and high-sensitivity fast reacquisition capability. This supports autonomous navigation, precise hovering, and landing for drones among buildings.
High-Precision GNSS Technology Empowers Intelligent Logistics Delivery
As drone delivery gradually becomes an important part of urban logistics, it places higher demands on the accuracy, reliability, anti-interference capability, and dynamic response of navigation systems. The Septentrio mosaic-G5 P3 is designed specifically for delivery drones with high-dynamic, high-reliability requirements, empowering every flight segment with laboratory-grade precision.
Why is Centimeter-Level GNSS Accuracy Crucial for Delivery Drones?
Precise landing point positioning, stable route tracking, reliable obstacle avoidance, and coordinated flight all depend on high-precision spatiotemporal information. Centimeter-level positioning not only improves delivery accuracy and reduces the need for human intervention but is also the foundation for achieving fully automated drone scheduling and cluster cooperative operations.
