PROBLEM TO BE SOLVED: To provide a GPS receiver which is connected to a computer network as a client and offloads a calculating load and a memory request to a network server. SOLUTION: In a synclient navigation satellite receiver network, measured values of GPS pseudo-range are collected and transmitted from a large number of independent clients to the server over the computer network. The server computes each navigation solution and returns it to the client, respectively. A client manager implemented in the server has a client request handler, and the client request handler interfaces the network and collects individual requests from each client. A perfect data set is made up from data being collected by the client request handler and corresponding to a period of 1-5 secs, and each job, where the preparation for sending is completed, is carried into a bank of the navigation server. A session manager controls communications between inputting and responding, and the output is sent to a client responder. COPYRIGHT: (C)2003,JPO |
