MS-based A-GNSS
MS-based A-GNSS method is through the PS region, so the customer must set the A-GNSS server and PDP context profile.
When using MS-based mode,
the mode will transform to standalone mode automatically after getting the ephemeris information from the server.
MS-based mode is serial fixed.
♦ The APN should be set to the real APN string set by the carrier.
♦ The GNSS server address is provided by the local carrier.
♦ The certificate is provided by a local carrier.
