    • For receiving GNSS data streams via NTRIP in real-time you may use the GNSS Internet Radio. This is an Ntrip Client program designed to run on a PC or Laptop. It retrieves data from any NTRIP supporting Broadcaster. The program handles the HTTP communication and transfers received GNSS data to a Serial or IP port to feed your application.

    Most of the data streams on the IGS-IP Ntrip Broadcaster are protected. Authorization is provided through a Registration form.
