A communications system for allowing a host system such as a GNSS satellite receiver to obtain a data communications connection is provided, comprising: a processor board connecting a cellular module, a WiFi module, and a radio module; and a communications selection means for automatically determining which module is capable of obtaining a data communications connection, wherein the communications selection means includes an algorithm that scans through the modules in a pre-defined order in search of the preferred communications connection, wherein the algorithm includes instructions to stop scanning when a module has found a valid connection. In one embodiment, the communications system further comprises a GNSS module connected to the processor board.
