KiwiSDR GPS shadow graph

The developer of the KiwiSDR, John Seamons, is constantly updating the software and introducing new features. One of these is the GPS shadow graph.

A few kilometers north of the receive site is Parlick Hill. Its peak is around 230 metres above the GPS antennas.

By viewing the graph on the administration interface, the shape of the hill can be determined from the absence of historic GPS signals received.
