Why do drones use GPS blending when flying in open environments?

Asked on Nov 21, 2025

Answer

Drones use GPS blending in open environments to enhance their navigation accuracy and reliability by combining data from multiple GPS receivers. This approach mitigates the effects of signal multipath, atmospheric conditions, and satellite geometry, ensuring more precise positioning and stable flight.

Example Concept: GPS blending involves integrating data from multiple GPS units to improve the accuracy and robustness of a drone's positioning system. By averaging the signals from different receivers, the system can filter out errors caused by individual satellite anomalies or environmental interference, leading to more reliable navigation and control in open environments.

Additional Comment:

GPS blending helps maintain accurate positioning even when some satellites provide poor signals.
It is particularly useful in environments with potential signal reflection or obstruction.
Combining GPS with other sensors like IMUs can further enhance navigation stability.
