A Continuously Operating Reference Stations (CORS) GNSS Network is essential to provide a regional positioning service that can provide fit-for-purpose positioning. For many GNSS applications only meter or sub-meter level positioning is required, but more and more often, centimeter accuracy positioning is required and an efficient measurement processes is increasingly demanded. CORS plays a major role in achieving these goals in many applications, for example, urban land parcel mapping, machine control,
precision agriculture, and utility mapping. To achieve this at a regional level, a CORS network needs to cover the complete region. In developing countries this represents significant challenges, yet offers
significant benefits.
In this paper, new technologies that can benefit from a CORS GNSS Network will be presented, and the various challenges of establishing a CORS network in emerging countries will be highlighted, and importantly, recommendations will be given on how best to overcome the many challenges based on
experiences gained with the establishment of many Networks.
