What is a GPS Drone?
A GPS drone is an unmanned aerial vehicle (UAV) equipped with a Global Positioning System (GPS) module. This advanced technology enables the drone to determine its precise geographical location by connecting to a network of satellites orbiting the Earth.
How GPS Works on Drones?
The GPS system operates through a network of satellites orbiting the Earth, which transmit signals to the drone's GPS module. Here’s a detailed look at the process:
- Satellite Signals: The Earth is surrounded by numerous GPS satellites that continuously send out signals. These signals contain information about the satellite's location and the exact time the signal was transmitted.
- Signal Reception: The GPS module inside the drone acts as a receiver for these signals. It picks up signals from multiple satellites simultaneously. The more satellites it can connect to, the more accurate the positioning.
- Triangulation: The GPS module calculates the time it takes for each signal to travel from the satellite to the drone. By measuring this time, the module can determine the distance to each satellite.
- Position Calculation: Using the distances from at least four satellites, the GPS module triangulates the drone's exact location in three-dimensional space (latitude, longitude, and altitude).

What Happens If A Drone Loses Its GPS Connection?
Drones rely heavily on GPS for navigation and features like Return to Home (RTH). But what happens if the GPS signal sputters or cuts out entirely? While it's not ideal, most drones are equipped to handle temporary GPS loss.
The drone's behavior depends on pre-programmed failsafe settings and the connection status with the controller. If GPS goes out but the controller signal remains strong, the drone will likely switch to a mode called "Attitude Hold" (ATTI).
In ATTI mode, the drone relies on internal sensors to maintain its altitude and angle, but it can drift with wind since it lacks positional awareness. Pilots can still control the drone in ATTI mode, but it requires more skill to keep it steady.
If both GPS and controller connections are lost, the failsafe settings come into play. These are typically programmed for the drone to either hover in place, land immediately or attempt an RTH using the last known GPS location (unreliable without a signal).
