Abstract
A method and system for communication in a real-time kinematic (RTK) positioning system by paging. An RTK positioning system having a reference station and a rover utilizes a paging system for data transfer. A single satellite positioning system (SATPS) reference station may be coupled to the paging system to provide RTK correction data, or multiple networked reference stations may be coupled to the paging system to provide data. Paging systems using allocated paging bands having fixed width channels (e.g. 20 kHz) such as those between 35 MHz and 36 MHz or 43 MHz and 44 MHz may be used.
