Navigation system, and control method and program for navigation system
First Claim
Patent Images
1. A navigation system, comprising:
- a signal receiver configured to receive a first signal and a second signal that is different from the first signal;
a memory storing a region estimation program; and
a processor that, when executing the stored program, estimates a region in which a current location is present on the basis of a combination of a status of reception of the first signal and a status of reception of the second signal by;
specifying a candidate region in which the current location may be present on the basis of a combination of a status of reception of the first and a status of reception of the second signal; and
relatively increasing a probability at which the current location is estimated to be present in the candidate region.

Abstract
Navigation systems, methods, and programs receive, with a signal receiver, a first signal and a second signal that is different from the first signal. The systems, methods, and programs estimate a region in which a current location is present on the basis of a combination of a status of reception of the first signal and a status of reception of the second signal.

12. A control method for a navigation system, the method comprising:
-
receiving, with a signal receiver, a first signal and a second signal that is different from the first signal; and estimating, with a processor, a region in which a current location is present on the basis of a combination of a status of reception of the first signal and a status of reception of the second signal by; specifying a candidate region in which the current location may be present on the basis of a combination of a status of reception of the first signal and a status of reception of the second signal; and relatively increasing a probability at which the current location is estimated to be present in the candidate region.

13. A non-transitory computer-readable storage medium storing a computer-executable control program for a navigation system, the program comprising:
-
instructions for receiving, with a signal receiver, a first signal and a second signal that is different from the first signal; and instructions for estimating a region in which a current location is present on the basis of a combination of a status of reception of the first signal and a status of reception of the second signal by; specifying a candidate region in which the current location may be present on the basis of a combination of a status of reception of the first signal and a status of reception of the second signal; and relatively increasing a probability at which the current location is estimated to be present in the candidate region.
