The Caster is a device that can receive RT data from different entities and broadcast this data in real time to multiple clients that are connected.

The Caster uses Networked Transport of RTCM (NTRIP) based on http protocol, to transport any GNSS data over the Internet and regardless of its GNSS data format (RTCM and/or raw).

For the CNES Caster, the RT data comes from GNSS stations, partners stations, external Casters, CNES internal centers of expertise. The diagram below shows the current interfaces of the CNES Caster. The Regina RT streams available at IGS could be requested through the link
