High-Precision GNSS Technology Empowers Modern Emergency Search and Rescue

In modern emergency search and rescue missions, drones have evolved from auxiliary tools into efficient and precise platforms for life detection and situational awareness. Critical steps such as rapid deployment, precise positioning, real-time path planning, and marking of target coordinates place extremely high demands on positioning accuracy and reliability. Traditional meter-level or decimeter-level accuracy can no longer meet the core requirements of search and rescue missions for time efficiency, positioning precision, and data reliability.

Why is Centimeter-Level GNSS Accuracy Crucial for Search and Rescue Operations?

A positioning deviation of 1-2 centimeters in complex terrain may lead to offset target coordinates, failure of drone obstacle avoidance, or inaccuracies in collaborative positioning. This not only wastes precious golden rescue time but can also directly impact the success rate of the mission. In challenging environments such as dense forests, mountainous regions, and urban ruins, precise GNSS positioning is the key technological foundation ensuring that drone search and rescue operations are efficient, reliable, and coordinated.

GNSS+ Technology Ensures Reliable Operation in Extreme Environments

The patented Septentrio GNSS+ technology suite ensures signal integrity remains intact under conditions potentially present at a search and rescue site, such as electromagnetic interference, multipath reflections, and strong vibrations:

– AIM+ Basic: Interference and spoofing signal detection and manual suppression, countering potential interference from communication equipment at the scene.

– APME+: Multipath mitigation, reducing interference from reflected signals off buildings, rocks, and trees.

– LOCK+: Maintains stable tracking under high vibration and strong wind gusts, adapting to drone maneuvers in complex airflow environments.

– RAIM+: Receiver Autonomous Integrity Monitoring, providing real-time positioning trust level indications, ensuring the reliability of critical coordinate data.

These technologies work together to deliver sustained and reliable centimeter-level RTK positioning accuracy:

– Horizontal Accuracy: 0.6 cm + 0.5 ppm

– Vertical Accuracy: 1.0 cm + 1 ppm
