The project requires either LimeSDR-Mini or LimeSDR-USB to work.

It consists of two parts: gps-simulator & limegps-network.

gps-simulator offers a friendly interactive UI and a backend to communicate with limegps-network, an enhanced version of limegps supporting server listening.

Mechanism:

[gps-simulator frontend] ----> [gps-simulator backend] ----> [limegps-network] ----> [LimeSDR]

Setup
