Dear colleagues,

we are pleased to announce the release of new real-time product streams from the Chinese Academy of Sciences (CAS) to support RT PPP-AR for GPS, Galileo and BDS-3 constellations. The newly generated CAS01 SSR product streams have been available on the IGS BKG caster since June 2025. Details are as follows:

IGS Caster: products.igs-ip.net
Mountpoints: SSRC01CAS1 (IGS-SSR, CoM), SSRA01CAS1 (IGS-SSR, APC), SSRC01CAS0 (RTCM-SSR, CoM), SSRA01CAS0 (RTCM-SSR, APC)
GNSS Constellations: GPS, Galileo and BDS-3 (i.e., G+E+C)
SSR Corrections: orbit, clock, code bias, phase bias, and global ionosphere.

In addtion, the CAS01 product streams, along with redistributed IGS data streams, CAS combined real-time ephmerides (BCEP00CAS0) and real-time VTEC (IONO01IGS1) SSR streams, are also accessible via CAS IGS Regional Data Center (https://igs.bdsmart.cn). Note that registration is required for access (cf., IGS-RTWG-Mail 358). 

We greatly appreciate your interest in these new product streams and your feedback is highly appreciated.

With kind regards,
