Abstract
The subject matter disclosed herein relates to determining whether a reported position of a wireless transmitter is sufficiently accurate in accordance with an accuracy metric based at least in part on a calculated range between an estimated position of a mobile station and the reported position and also based at least in part on one or more measurements taken from one or more signals transmitted by the wireless transmitter.
Claims27
A server-based method of determining uncertainty, comprising:
- receiving a reported position associated with a wireless transmitter;
- estimating, by the server, a position of a mobile station at a first point in time;
- calculating a range between the reported position associated with the wireless transmitter and the estimated position of the mobile station;
- determining, by the server, a position uncertainty value for the reported position associated with the wireless transmitter, the position uncertainty value representative of a level of correlation between one or more measurements, related to one or more signals transmitted from the wireless transmitter, and the calculated range between the reported position associated with the wireless transmitter and the estimated position of the mobile station;
- and
- sending said position uncertainty value to a base station almanac database server.
3 more elements
A server, comprising:
- a receiver to:
- receive a reported position associated with a wireless transmitter;
- and
- a processing unit to:
- estimate at least in part a position of the mobile station at the first point in time;
- calculate, at least in part, a range between the reported position associated with the wireless transmitter and the estimated position of the mobile station;
- calculate a position uncertainty value for the reported position associated with the wireless transmitter, the position uncertainty value representative of a level of correlation between one or more measurements, related to one or more signals transmitted from the wireless transmitter, and the calculated range between the reported position associated with the wireless transmitter and the estimated position of the mobile station;
- and
- send said position uncertainty value to a base station almanac database server.
6 more elements
A server, comprising:
- means for receiving a reported position associated with a wireless transmitter;
- means for estimating a position of the mobile station at the first point in time;
- means for calculating a range between the reported position associated with the wireless transmitter and the estimated position of the mobile station;
- means for determining a position uncertainty value for the reported position associated with the wireless transmitter, the position uncertainty value representative of a level of correlation between one or more measurements, related to one or more signals transmitted from the wireless transmitter, and the calculated range between the reported position associated with the wireless transmitter and the estimated position of the mobile station;
- and
- means for sending said position uncertainty value to a base station almanac database server.
3 more elements
A non-transitory article of manufacture, comprising:
- a storage medium having stored thereon instructions that, if executed by a processing unit of a server, enable the processing unit to:
- receive a reported position associated with a wireless transmitter;
- estimate a position of the mobile station at a first point in time;
- calculate a range between the reported position associated with the wireless transmitter and the estimated position of the mobile station;
- determine, by the server, a position uncertainty value for the reported position associated with the wireless transmitter, the position uncertainty value representative of a level of correlation between one or more measurements, related to one or more signals transmitted from the wireless transmitter, and the calculated range between the reported position associated with the wireless transmitter and the estimated position of the mobile station;
- and
- send said position uncertainty value to a base station almanac database server.
