+The People's Republic of China is developing its own SBAS, called BeiDou satellite-based augmentation system (BDSBAS and formerly Satellite Navigation Augmentation System (SNAS)) to provide SBAS services in China and sorrounding regions.
 In 2002, the company [http://www.novatel.com/ Novatel] was awarded <ref>[http://findarticles.com/p/articles/mi_m0BPW/is_2_13/ai_n27573643/ NovAtel gains China order, GPS World, Feb. 2002]</ref> with a contract for the provision of 12 receivers for the phase II of the development, and the receivers have already been delivered. These stations would complement the 11 ones already installed in and around Beijing for the phase I of the program.
-During the presentation of the development status of the [[BeiDou General Introduction|BeiDou]] system  in the ION-GNSS 2011 congress,<ref>”Development of BeiDou Navigation Satellite System”, China Satellite Navigation Office, Sep 2011, ION GNSS 2011.</ref> the China Satellite Navigation Office listed the [[BeiDou Services|services]] that the BeiDou System would provide, and one of them was the wide range differential service, aiming at a positioning accuracy of 1 m; presumably, this wide range differential service corresponds to the SNAS system.
+BDSBAS is integrated in the BeiDou system and uses BDS-3 type satellites to broadcast SBAS L1/L5 signal, augmenting BDS and GPS. If they are recommended by ICAO SARPs, Galileo E1C/E5a and GLONASS L1/L3 will also be considered <ref name="GSBAS/SBAS">[https://www.icao.int/APAC/APAC-RSO/GBASSBAS%20Implementation%20Workshop/3-5_GBAS-SBAS%20Implementation%20in%20China%20(X%20Li).pdf GSBAS/SBAS Implementation in China], ICAO ASIA/PACIFIC REGIONAL GBAS/SBAS WORKSHOP, Seoul, ROK, 3~5 June 2019</ref>.
-There is little public information available on the SNAS development at the time of writing this article.
