This document describes a means of acquiring Global Navigation Satellite System (GNSS) assistance data using HTTP. Assistance data aids GNSS receivers in acquiring and measuring satellite signals, as well as being useful in calculating positions. The GNSS Reference Information Protocol (GRIP) provides a framework for discovering resources capable of providing any kind of location-based assistance data.
