How Drone GNSS-Based Positioning Works in Practice

Drone GNSS-based positioning operates through a series of steps:

1. Signal Reception: The drone's GNSS receiver captures signals from multiple satellites.
2. Triangulation: Using the time it takes for signals to travel, the receiver calculates the drone's position through triangulation.
3. Data Processing: The GNSS receiver processes the data to determine latitude, longitude, altitude, and velocity.
4. Integration with Flight Systems: The positioning data is integrated into the drone's flight control system, enabling precise navigation.
5. Error Correction: Advanced techniques like RTK (Real-Time Kinematic) and PPP (Precise Point Positioning) are used to correct errors caused by atmospheric interference or satellite geometry.
