Abstract: Radio link coverage mapping systems and related techniques are provided to improve the operation of unmanned mobile sensor or survey platforms. A radio or communication link coverage mapping system includes a logic device configured to communicate with a communication module and a position sensor coupled to a mobile platform, where the communication module is configured to establish a wireless communication link with a base station associated with the mobile platform and the position sensor is configured to provide a position of the mobile platform as it maneuvers within a survey area. The logic device determines communication link quality data associated with the wireless communication link as the mobile platform maneuvers within the survey area, receives corresponding position data, and generates corresponding communication coverage information, which may be used to generate a radio link coverage map.

Abstract: The present invention relates to a system and a method for measuring and determining the depth, offset and translation in relation to one or several features in the field of view of an image sensor equipped UAV. The UAV comprises at least an autopilot system capable of estimating rotation and translation, processing means, height measuring means and one or more imaging sensor means. Given the estimated translation provided by the autopilot system, the objective of the present invention is achieved by the following method; capturing an image, initiating a change in altitude, capturing a second image, comparing the images and the change in height provided by the sensor to produce a scale factor or depth. If depth is estimated, then calculating the scale factor from the depth, and calculating the actual translation with the resulting scale factor.
