GPS III arrived - An initial Analysis of Signal Payload and Achieved User Performance

Kurzfassung

The global positioning system (GPS) is the pioneer under the present and developing global Navigation satellite systems (GNSS). In the beginning of this year a new milestone has been reached with the start of the signal transmission of the first GPS Block III space craft, which was launched with a Falcon 9 rocket from Cape Canaveral, Florida, on December 23, 2018. The satellites of this new GPS generation are built by Lockheed Martin and contain a wide range of technological improvements and new features compared to their predecessors, while maintaining compatibility with other satellites in the constellation for navigation users. The transmission of the L1 C/A, L1 P(Y) and L2 P(Y) signals has been started on January 9, 2019. Within this work an initial signal quality analyses and user perferomance assessment is conducted.
