SYSTEMS AND METHODS FOR ESTIMATING A TWO-DIMENSIONAL POSITION OF A RECEIVER |
| 摘要 |
Estimating a two-dimensional position of a receiver based on an altitude of an object other than the receiver in a geographical region within which the receiver is believed to reside. In one embodiment, when a high-accuracy estimate of the receiver's altitude is available, latitude and longitude coordinates of the receiver are estimated using the high-accuracy estimate of the receiver's altitude. When the high-accuracy estimate of the receiver's altitude is not available, the latitude and longitude coordinates of the receiver are estimated using an alternative altitude value that is based on one or more altitudes of one or more things other than the receiver. |

1. A method for estimating latitude and longitude coordinates of a receiver, the method comprising:
determining whether a high-accuracy estimate of a receiver's altitude is available; when the high-accuracy estimate of the receiver's altitude is available, estimating latitude and longitude coordinates of the receiver using the high-accuracy estimate of the receiver's altitude; and when the high-accuracy estimate of the receiver's altitude is not available, estimating the latitude and longitude coordinates of the receiver using an alternative altitude value that is based on one or more altitudes of one or more things other than the receiver. |
