This sample code is a simple client that asks for assistance data from a location server. It can handle OSR, SSR, and AGNSS requests. The assistance data can converted to RTCM or SPARTN before being sent to a GNSS receiver or other interface. The client also supports to 3GPP LPP Provide Location Information, which can be used to send the device's location to the location server.
There are a few required arguments:
-hor--host- The host of the location server-cor--mcc- The Mobile Country Code-nor--mnc- The Mobile Network Code-tor--tac- The Tracking Area Code-ior--ci- The Cell Identity

3GPP LPP Example (3.4.4) - This sample code is a simple client that asks for
assistance data from a location server. It can handle OSR, SSR, and AGNSS
requests. The assistance data can converted to RTCM or SPARTN before being
sent to a GNSS receiver or other interface. The client also supports to 3GPP
LPP Provide Location Information, which can be used to send the device's
location to the location server.
