Kurzfassung

During the flight of a sounding rocket often multiple ground stations are used to receive telemetry data. The overlapping time in which the telemetry stations can receive data from the rocket is rather high (up to 100%), compared to other setups like air and space applications, where it is only used to switch from one ground station to another. This, and the knowledge about the data format of the transmission protocol allow new approaches for Best-Source-Selection and error correction. This thesis provides a working software implementation which enables the enhancement of data streams received by multiple ground stations from the same transmitter by conflation of the streams and performing forward error correction. For the forward error correction the existing protocol had to be analyzed to get the used error correction algorithm and with it the statistical information on wrong detection possibilities. The usage of a higher OSI-Level together with the long overlapping times of data streams allows to build a software with advanced capabilities compared to simple Best Source Selectors. It provides the possibility to replace defect frames in the output by validated ones of other inputs and furthermore eliminate even wrongly detected errors.
