The Critical Role of High-Precision GNSS in Wildlife Conservation
As ecological protection technology advances toward intelligence and refinement, drones have become core tools for animal tracking, habitat monitoring, anti-poaching patrols, and population surveys. Wildlife conservation missions demand extremely high continuity and reliability of spatiotemporal information. Drones must continuously provide precise position, attitude, and timestamps in complex natural environments such as jungles, grasslands, and mountainous areas. The Septentrio AsteRx-m3 Pro+, a high-performance, low-power GNSS board, delivers centimeter-level Real-Time Kinematic (RTK) positioning and 3D attitude sensing capabilities for conservation drones, serving as the key sensor to ensure monitoring data meets scientific research and law enforcement standards.
Why Do Wildlife Conservation Drones Need High-Performance GNSS Boards?
Wildlife conservation operations take place in special and challenging environments:
- Precise Tracking and Data Correlation: Studies on animal movement trajectories, habitat utilization, and anti-poaching investigations require drones to provide centimeter-level positioning, ensuring accurate binding of observation points, infrared thermal images, and video data with geographic coordinates.
- Complex Natural Environment Challenges: Satellite signals are prone to obstruction and multipath interference in dense forests, canyons, and river areas, with risks of natural or man-made radio interference.
- Stealth and Stable Operation Requirements: Monitoring missions demand quiet and smooth drone flights to avoid disturbing animals, while maintaining stable positioning and attitude during high-dynamic flights (e.g., tracking moving targets).
- Long-Duration Endurance and Reliability: Protected areas are vast, and missions last for extended periods. Navigation devices must be ultra-low power and adaptable to field conditions such as humidity, large temperature differences, and vibrations.
With its exceptional positioning accuracy, powerful GNSS+ anti-jamming technology, industrial-grade reliability, and ultra-low power design, the Septentrio AsteRx-m3 Pro+ is the ideal navigation core for wildlife conservation drones to achieve precise monitoring, reliable patrolling, and efficient management.

Frequently Asked Questions
How does the AsteRx-m3 Pro+ ensure effective positioning in dense forests?
The AsteRx-m3 Pro+ features multi-constellation, multi-frequency tracking (544 channels) that maximizes satellite visibility under tree canopy where signals are weak. Its high-sensitivity tracking and APME+ multipath mitigation reduce signal reflection errors from tree canopies, mountain slopes, and water surfaces. For severely attenuated signals, tight coupling with an IMU maintains positioning continuity during canopy gaps.
How does the board collaborate with mission payloads like infrared thermal imagers?
The AsteRx-m3 Pro+ provides event marker pins with nanosecond-precision accuracy for synchronizing camera exposure with GNSS time. This enables precise geotagging of infrared and visual images, ensuring animal sightings, heat signatures, and location data are accurately correlated. The board also supports PPK post-processing for the highest georeferencing accuracy.
What are the power consumption and environmental specifications for long-term monitoring?
The AsteRx-m3 Pro+ consumes approximately 750 mW to 1000 mW depending on tracking mode, making it suitable for long-endurance conservation drone missions. It operates from -40°C to +85°C and complies with MIL-STD-810G for vibration and shock, ensuring reliable performance in field conditions with humidity, temperature variations, and rugged handling common in protected area operations.
How to achieve high-precision positioning in remote protected areas without network coverage?
In areas without cellular or internet coverage, PPK (Post-Processed Kinematic) is the recommended approach. Deploy a temporary GNSS base station at a known location in the reserve, or use a portable reference receiver. Both the aircraft and base station record raw observation data during flights. Post-mission processing resolves centimeter-level trajectories without requiring real-time RTK correction links.
