Real-Time GNSS Data and Products now available through the CDDIS
News Date: 04/10/2015
NASA's Crustal Dynamics Data Information System (CDDIS) is pleased to announce that its real-time caster is now operational, supporting the International GNSS Service (IGS) Real-Time Service (RTS). The IGS RTS, based on a cooperative global infrastructure of stations, data centers, and analysis centers, provides GNSS orbit and clock corrections that enable precise point positioning (PPP) and related applications, such as time synchronization and disaster monitoring at global scales. CDDIS caster utilizes the Networked Transport of RTCM via Internet Protocol (NTRIP) software to disseminate these real-time streams to registered users.
CDDIS has incorporated the Earthdata Login to handle user signup and access authentication. At this time, CDDIS is making real-time data available from 155 sites (see map) as well as 37 product streams. Future plans include the addition of more station data streams and computation and conversion of these data streams into high‐rate data files for the CDDIS online archive. More information about CDDIS caster and real-time data and products is available from the CDDIS website.
