Abstract
A method for distributing locating-relevant information includes providing a GPS position of a client to a server on a data network, and returning location-relevant information by the server based on the specified GPS position. Such location-relevant information include travel or tourist information (e.g., locations of tourist attractions, hotels, or restaurants). Commercial information such as discount coupons or advertising selected based on the Client's GPS position can also be provided. Financial or business transactions can be conducted using the GPS position for authentication or identification.
Claims55
A locating system receiving positional information from a mobile unit via a data network, comprising a data processing station connected to a data network accessible by said mobile unit using a wireless communication network through a gateway bridging said data network and said wireless communication network, said data processing station having a database including location references, wherein when said data processing station receives said positional information, said data processing station computes a measured position for said mobile unit, stores said measured position of said mobile unit in said database, associates said measured position of said mobile unit with a location reference in said database, creates from said location reference a second location reference embedded therein a marker indicating said measured position of said mobile unit, and provides, through said data network, said second location reference for display.
A method for locating a mobile unit, comprising:
- at a data processing station, receiving from said mobile unit over a data network through a gateway bridging said data network and a cellular network a set of positional data representing the position of said mobile unit;
- storing said positional data in a database for later retrieval;
- retrieving said positional data in said processing station and computing a measured position of said mobile unit;
- creating a location reference embedded therein a marker indicating said measured position of said mobile unit;
- and
- providing, through said data network, said location reference for display.
A method for calculating a corrected measured position of a mobile unit at a data processing station, comprising:
- receiving from said mobile unit positional information of said mobile unit through a gateway bridging a data network and a wireless communication system;
- receiving differential correction data corresponding in time to said positional information from a differential correction station;
- sending said differential correction data to said mobile unit, so as to allow said mobile unit to calculate a corrected measured position;
- based on said positional information and said differential data.
A storage medium including a computer program for carrying out a method for locating a mobile unit, said method comprising:
- at a data processing station, receiving from said mobile unit over a data network through a gateway bridging said data network and a wireless communication system a set of positional data of said mobile unit;
- storing said positional data in a database for later retrieval;
- retrieving said positional data in said processing station and computing a measured position of said mobile unit;
- creating a location reference embedded therein a marker indicating said measured position of said mobile unit;
- and
- providing, through said data network, said second location reference for display.
A storage medium including a computer program for carrying out a method for calculating a corrected measured position of a mobile unit at a data processing station, said method comprising:
- receiving from said mobile unit positional information of said mobile unit through a gateway bridging a data network and a wireless communication network;
- receiving differential correction data corresponding in time to said positional information from a differential correction station;
- sending said differential correction data to said mobile unit, so as to allow said mobile unit to calculate a corrected measured position;
- based on said positional information and said differential data.
