    • A method and system for providing a user with correction information for use in accurately determining the location of the user. A plurality of monitor stations are disposed at a plurality of known fixed locations for monitoring a plurality of navigation data messages transmitted by Global Positioning Systems (GPS) Space Vehicles (SVs) and for determining a plurality of corresponding correction factors. A central ground station is operatively coupled to each of the plurality of monitor stations for receiving the plurality of correction factors from each of the plurality of monitor stations. A GPS transceiver receives at least one of the plurality of navigation data messages at an unknown location and determines a general location of the user. The general location of the user is then transmitted to the central ground station. The central ground station determines user location correction data based on the navigation data received by the user and the plurality of correction factors transmitted by each of the plurality of monitor stations. The central ground station then transmits the user location correction data to the user for use in determining the location of the user with sub-meter precision. An accounting record may be created for the user for receiving the precision correction information so that the user can be subsequently billed a fee for the services provided by the central ground station.
    • 一种用于向用户提供用于准确地确定用户位置的校正信息的方法和系统。 多个监视站设置在多个已知的固定位置,用于监视由全球定位系统(GPS)空间车辆(SV)发送的多个导航数据消息并用于确定多个对应的校正因子。 中央地面站可操作地耦合到多个监测站中的每一个,用于从多个监测站中的每一个接收多个校正因子。 GPS收发器在未知位置处接收多个导航数据消息中的至少一个,并确定用户的一般位置。 然后将用户的一般位置发送到中央地面站。 中央地面站基于用户接收的导航数据和由多个监视站中的每一个发送的多个校正因子来确定用户位置校正数据。 然后,中央地面站将用户位置校正数据发送给用户,以用于以子计精度确定用户的位置。 可以为用户创建用于接收精度校正信息的会计记录,使得用户随后可以为中央地面站提供的服务收取费用。
