In the last few years, Unmanned Aerial Systems (UAS) have been attracting enormous research interest, being employed in military and civilian missions (e.g. search and rescue, disaster assessment, urban traffic monitoring, 3D mapping, etc.) that would be risky or impossible for a human to perform. For autonomous or aided operations (e.g. automatic or aided landing), it is crucial to have on board...
We investigated ways to apply the ICAO standard atmosphere to altitude estimation using the atmospheric pressure sensor in mobile terminal. Two error factors in particular were found to affect estimation accuracy. We tested an estimation method that corrects for the current sea-level pressure and current sea-level temperature by using external weather information. We were able to estimate altitude...
