Abstract
A test device determines a Global Navigation Satellite System (GNSS) signal propagation delay in a GNSS signal distribution system (GSDS) for a radio access network, and can further perform long-term tests on a GSDS without having access to a GNSS satellite. The test device includes a GNSS receiver and a clock that can be re-tuned to accommodate performing tests on the GSDS.
