Abstract
A positioning system offers positioning information on the basis of a signal transmitted from a quasi-zenith satellite. Multiple reference stations disposed on the ground receive signals from a plurality of positioning satellites. A communication station corrects the signals the reference stations have received, and transmits them to the quasi-zenith satellite. A positioning information offering apparatus transmits the signal received from the quasi-zenith satellite and a positional information to a positioning apparatus.
Claims16
A positioning system for offering positioning information on the basis of a signal transmitted from a quasi-zenith satellite, wherein said signal includes another signal transmitted to said quasi-zenith satellite from a communication station after being produced as a result of processing still other signals received from a plurality of positioning satellites by multiple reference stations placed on the ground, and a positioning information offering apparatus is provided to transmit said signal sent from said quasi-zenith satellite and a positioning information of said positioning system.
A positioning system connected via a network to a communication station that offers positioning information, wherein a positioning information offering apparatus is provided to transmit a positioning information of said positioning system and other positioning information that is offered from said communication station after being produced by processing the signals received from a plurality of positioning satellites by multiple reference stations.
A positioning system for offering positioning information on the basis of a signal transmitted from a quasi-zenith satellite, wherein said signal includes another signal transmitted to said quasi-zenith satellite after being produced as a result of processing still other signals received at multiple places from a plurality of positioning satellites, and a positioning apparatus is provided to detect a position of said positioning system by receiving a composite signal from a positioning information offering apparatus that is placed on the ground to combine said signal sent from said quasi-zenith satellite and its own positioning information and to transmit said composite signal.
A positioning information offering method for offering positioning information on the basis of a signal transmitted from a quasi-zenith satellite, wherein said signal includes another signal transmitted to said quasi-zenith satellite from a communication station after being produced as a result of processing still other signals received from a plurality of positioning satellites by multiple reference stations placed on the ground, and a positioning information offering apparatus is provided to transmit said signal sent from said quasi-zenith satellite and a positioning information of said positioning system.
A positioning information offering method comprising the steps of:
- receiving positioning-information by an apparatus from a communication station after processing signals received by a plurality of reference stations from multiple positioning satellites;
- and transmitting said positioning information and other positioning information of said apparatus.
A positioning information offering method for offering positioning information on the basis of a signal transmitted from a quasi-zenith satellite, wherein said signal includes another signal transmitted to said quasi-zenith satellite after being produced as a result of processing still other signals received at multiple places from a plurality of positioning satellites, and a positioning apparatus is provided to detect position by receiving a composite signal from a positioning information offering apparatus that is placed on the ground to combine said signal sent from said quasi-zenith satellite and positioning information and to transmit said composite signal.
