The Russian Satellite Based Augmentation System (SBAS) is reported to be transmitting GPS differential corrections.

Luch-5A, a geostationary comms satellite that carries the System for Differential Correction and Monitoring (SDCM) transponder, has started transmitting GPS corrections - according to Javad Ashjaee, CEO of Javad Navigation Systems.

He reported that L1 signals, using PRN code 140, were received by Javad receivers on 14 July and used to compute code-differential positions. Only GPS corrections - not GLONASS - have been received to date.

Luch-5A has recently been repositioned at 95ºE in an apparent switch of positions with Luch-5B, which is scheduled for launch later this year. Luch-5A is also using the GPS PRN code previously assigned to Luch-5B - so it appears to be a complete swap of 5A and 5B functions.
