U-Blox M8 evaluation kit

he basic concept of the experiment is to define the trajectory of a UAV using a low-cost GNSS receiver. In this UAV is installed a camera, a laser altimeter and one single-frequency GNSS receiver. In the future it will be used for remote sensing applications, but due to this fact, the position of the UAV must be defined very well every moment. This experiment is done in order to find the limits of the accuracy that can be achieved using a single-frequency receiver for different baselines between the rover (the UAV) and the base station. The laser altimeter will be used for creating a DTM of the area, which is under investigation, and the camera can be used for photogrammetric applications. Such applications can be combined with the data of the GNSS receiver.
Before the final experiment, were done some others in order to check the behaviour of the receiver in dynamic mode. For this reason the receiver was installed on a bike, while the bike was cycling measurements were taken. This experiment took place in Volkspark (Potsdam) and in Tempelhof (Berlin).
