There are 19 CORS in Hong Kong. Ten stations are built at hilltop with a 5m high pillar and fenced to avoid disturbance. The other nine stations are installed on building rooftop. The separation of the reference stations is about 10 to 15km. This is to provide at least two stations within 10km for users in most of the area in Hong Kong.
