The radio blind-chess guiding system does not deliver the longitude and latitude degree directly. It has a strong secrecy, long-distance transmission and not be influenced by watching-distance. The system can carry out long-distance, low altitude guiding. This paper discusses the partition of airspace in the radio blind-chess guiding system. Through comparing and analyzing several selective projects: rectangle (square), special hexagon and circle, a conclusion is made that in the wireless blind-chess guiding system the square district is the best of all.
