-QZSS and Beidou are regional GPS augmentation systems using
-geostationary satellites fielded by Japan and China respectively.
+QZSS is a geosynchronous (*not geostationary*) system of three
+(possibly four)
+satellites in highly eliptical, inclined, orbits. It is designed to
+provide coverage in Japan's urban canyons.
+
+BeiDou-1 consists of 4 geostationary satellites operated by China,
+operational since 2004. Coverage area is the Chinese mainland.
+BeiDou-2 (also known as COMPASS) is a system of 35 satellites,
+including 5 geostationary for compatability with BeiDou-1. It is
+expected to be fully operational by 2019. Coverage area is worldwide.
