GPS quality
DronePal looks beyond satellite count alone, using GPS quality information including satellite availability and dilution of precision.
DronePal independently checks the local environment before takeoff — assessing GPS quality, magnetic interference and RF interference, then presenting a clear overall flight-risk indication.
Good pilots check the weather.
Smart pilots check DronePal.

Satellite geometry can be poor, nearby magnetic fields can disturb compass-dependent systems, and local radio activity can create a noisy operating environment. DronePal is designed to give the pilot another layer of information before committing to takeoff.
Each area is assessed independently and then contributes to the overall flight-risk indication.
DronePal looks beyond satellite count alone, using GPS quality information including satellite availability and dilution of precision.
Measures the local magnetic environment to identify conditions that may be undesirable for compass-dependent flight systems.
Measures local radio-frequency activity to help identify electrically noisy operating sites before the aircraft leaves the ground.
DronePal does more than display a satellite count. It independently evaluates three parts of the local operating environment, then brings those measurements together into a clear pre-flight risk indication.
DronePal evaluates satellite availability and constellation geometry rather than relying on satellite count alone. Satellite count and HDOP — Horizontal Dilution of Precision — provide an indication of how favourably the visible satellites are positioned for reliable horizontal positioning.
A large number of satellites does not automatically mean good geometry. DronePal assesses the quality of the constellation as well as the quantity.
DronePal monitors the magnitude of the local magnetic field and looks for abnormal influence from nearby ferrous material, vehicles, structures, electrical equipment and other magnetic sources.
DronePal is not trying to act as another compass. It is looking for magnetic conditions that may influence compass-dependent systems in the aircraft.
DronePal measures the local radio-frequency energy level to identify an electrically noisy operating site. Elevated RF activity can reduce the operating margin available to radio-dependent systems and may justify additional caution before takeoff.
The RF indication is intended as an environmental warning tool — not as a frequency-selective spectrum analyser.
The GNSS, magnetic and RF assessments remain visible individually, but DronePal also combines them into an overall Low, Medium or High flight-risk indication. This lets the pilot see both the underlying measurements and the final assessment at a glance.
DronePal uses a simple three-button interface and a high-contrast display so the information that matters can be read quickly at the flying site.






Place DronePal where you intend to operate and allow it to assess the local environment.
Check GPS quality, magnetic interference and RF interference independently.
DronePal combines the measurements into a simple Low, Medium or High flight-risk indication.
DronePal provides additional information. The decision to fly remains with the pilot.
No. DronePal is designed as an independent pre-flight analysis device rather than a replacement for the drone’s own safety systems.
No. DronePal is an additional source of information. Weather, aircraft condition, local regulations, obstacles, pilot judgement and other operational factors still need to be considered.
It combines the measured GPS, magnetic and RF conditions into a simple Low, Medium or High indication intended to support the pilot’s pre-flight decision.
The development unit includes protected setup functions for sensitivity and risk weighting. Final production specifications may change as testing continues.
