The estimate, as it arrives over the API

Everything on this page came through the chain below: the terminal codes the particle filter's estimate as LPP inside SUPL, the SLP decodes it, the GMLC sends it to this application as Ngmlc EventNotify. Shown are the standard 3GPP shape, the mixture carried as an extension, and the notifications as received. This page has its own subscription: pause it, or ask for the position once. While no device is live, a recorded ride plays in a loop; the badge on the map says which you are watching.

An integration path over 3GPP interfaces with simulated network functions: the terminal side is real, the SLP and the GMLC are local mocks.
