1. A method operative in a satellite receiver, comprising:
- receiving first satellite state information from at least one satellite;
identifying an erroneous satellite based on the first satellite state information, and restricting the use of a satellite signal received from the identified erroneous satellite;
receiving second satellite state information from a server;
updating a satellite state of the at least one satellite using the second satellite state information; and
when the updated satellite state contradicts an erroneous state of the identified satellite, lifting the restriction on the use of the signal from the identified satellite.

Abstract
Provided is a system and method for transmitting a satellite state to a satellite receiver to determine use or non-use of a satellite signal in positioning estimation. A satellite navigation system includes at least one satellite, a satellite control center for controlling the at least one satellite, and a server. The server transmits satellite state information about the at least one satellite identified through the satellite control center to the satellite receiver. The satellite receiver restricts the use of the satellite signal for positioning estimation when the satellite state is identified as erroneous.

5. A satellite receiver comprising:
-
a satellite receiving unit configured to receive a satellite signal; a communication unit configured to communicate with a server; and a control unit configured to; receive first satellite state information from at least one satellite through the satellite receiving unit; identify an erroneous satellite based on the first satellite state information, and restrict the use of a satellite signal received from the identified erroneous satellite; receive second satellite state information from a server through the communication unit; update a satellite state of the at least one satellite using the second satellite state information; when the updated satellite state contradicts an erroneous state of the identified satellite, lift the restriction on the use of the signal from the identified satellite. - View Dependent Claims (6, 7, 8)
