SBAS systems are spreading out all over the world. More and more, it is believed that upon dual-frequency SBAS service provision, a seamless navigation will be possible from and to any two locations in the world.

From all the SBAS systems in the world, three are already operational ([[WAAS General Introduction|WAAS]], [[MSAS General Introduction|MSAS]], [[EGNOS General Introduction|EGNOS]]), three are under implementation ([[GAGAN]], [[SDCM]], [[SNAS]]) while others are under feasibility studies, for instance SACCSA.

There is little public information available on this development.
China is moving forward with its own version of a SBAS. Although information
on their system is incomplete, at least 11 reference sites have been installed in and around Beijing in Phase I of the program, and further expansion is anticipated.
Receivers manufactured by Novatel, Inc. of Canada have been delivered for
Phase II.

The People's Republic of China is developing its own SBAS, called Satellite Navigation Augmentation System (SNAS). The company Novatel was awarded in 2002 [1] with a contract for the provision of 12 receivers for the phase II of the devolvement, 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. There is no more public information available on the SNAS development.
