High-Precision GNSS Technology Empowers Intelligent Logistics Delivery
As drone delivery becomes an important part of urban logistics, it places high demands on the accuracy, reliability, anti-interference capability, and dynamic response of navigation systems. The Septentrio mosaic-G5 P3 is designed for delivery drones, empowering every flight segment with laboratory-grade precision.
Why Is Centimeter-Level GNSS Accuracy Crucial for Delivery Drones?
Quad-constellation GNSS receivers achieve centimeter-level accuracy by simultaneously tracking GPS, GLONASS, Galileo, and BeiDou satellites with RTK corrections. This level of precision not only improves delivery accuracy and reduces human intervention but is also the foundation for fully automated drone scheduling and cluster cooperative operations.

- Comprehensive protocol support: SBP, NMEA 0183 (v2.3/v3.03/v4.0), RTCM 3.x including MSM
- Wide temperature operation: -40°C to +85°C operating, -55°C to +85°C storage
GNSS+ Technology Ensures Stable Positioning in Complex Urban Scenarios
Septentrio’s unique GNSS+ technology suite maintains high-precision positioning in cities with dense buildings and complex electromagnetic environments:
- AIM+ Advanced: Real-time suppression of interference and spoofing, ensuring signal purity
- APME+: Effectively suppresses multipath errors from building and vehicle reflections
- LOCK+: Maintains stable signal lock during drone maneuvers and wind disturbances
- IONO+: Mitigates ionospheric disturbances for all-weather reliability
These technologies deliver outstanding RTK positioning performance (open sky, baseline <40 km):
- Horizontal Accuracy: 0.6 cm + 0.5 ppm
- Vertical Accuracy: 1.0 cm + 1 ppm
- Initialization Time: Typically 7 seconds

Frequently Asked Questions
What GNSS accuracy is needed for precision delivery drones?
Precision delivery drones need better than 10 cm RTK accuracy for safe landing at designated drop zones, especially in urban or suburban environments. The mosaic-G5 P3 achieves 2.5 cm RTK accuracy, enabling the drone to consistently land within a small target area and avoid obstacles on final approach.
How does the mosaic-G5 P3 handle urban canyon GNSS challenges in delivery operations?
The mosaic-G5 P3 supports multi-constellation multi-frequency tracking, maximizing satellite availability in urban canyons where sky view is limited. Its AIM+ interference mitigation filters out RF noise from city infrastructure. For the most challenging urban deliveries, integrating GNSS with inertial sensors and vision-based landing provides redundancy.
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, complete raw data output supporting PPK post-processing verification, ultra-low power consumption, and small size suitable for various small and medium-sized delivery drones. Its anti-interference and multipath mitigation technologies ensure continuous, reliable positioning in dense urban areas.
Why do delivery drones need centimeter-level GNSS accuracy?
Centimeter-level positioning accuracy is key to ensuring drones land precisely at pickup and delivery points, enabling automated loading and unloading, and avoiding collisions with obstacles. Even decimeter-level deviations can cause drones to stray from the intended landing zone, impacting delivery safety and operational efficiency.
