AN2077: Localised GPS

The basic need associated with a system like this is to get position information about the occupants of a localised area eg. A Campus or Univ. The localised area is fragmented into hypothetical cells that are scanned by an overhead server having a high directivity helical antenna. Each authorised subscriber or client has hand-held equipment that communicates with the server. In this way the server maintains a postion map about each client. A client can get the information about the position of any other client by requesting the server for the same. The information retreived is displayed as a visual map of the area. The system is modular in nature and has single frequency opeartion thereby requiring simplified hardware and software. As an additional feature the client equipment is provided with a temperature logger.
