GPS Remote Sensing Measurements Using Aerosonde UAV [PDF]
Infotech@Aerospace, 2005 In February 2004, a NASA-Langley GPS Remote Sensor (GPSRS) unit was flown on an Aerosonde unmanned aerial vehicle (UAV) from the Wallops Flight Facility (WFF) in Virginia. Using direct and surface-reflected 1.575 GHz coarse acquisition (C/A) coded GPS signals, remote sensing measurements were obtained over land and portions of open water.

Investigation on the automatic geo-referencing of archaeological UAV photographs by correlation with pre-existing ortho-photos [PDF]
, 2014 We present a method for the automatic geo-referencing of archaeological photographs captured aboard unmanned aerial vehicles (UAVs), termed UPs. We do so by help of pre-existing ortho-photo maps (OPMs) and digital surface models (DSMs).

Noise and Restoration of UAV Remote Sensing Images [PDF]
International Journal of Advanced Computer Science and Applications, 2020 Remotely sensed images captured from a camera mounted on a UAV (unmanned aerial vehicle) are exposed to noise caused by internal factors, such as the UAV system itself or external factors such as atmospheric conditions. Such images need to be restored before they can undergo further processing stages.
