Method and apparatus for processing data in a GPS receiving device in a road vehicle
First Claim
1. A method for processing data received by a receiving device outputting present location data for a vehicle carrying said device based on radio waves from a plurality of satellites, said method comprising the steps of:
- determining if said vehicle is stopped;
calculating an average of a predetermined number of data inputted into said receiving device while said vehicle is stopped;
determining said average as an effective data if a standard deviation of said predetermined number of data is within a predetermined range; and
calculating a present location of said vehicle from said effective data.

Abstract
A method for processing data received by a receiving device which outputs present location data for a movable vehicle based on the Global Positioning System and is positioned in the vehicle, including the steps of calculating an average of a predetermined number of data output from the receiving device while the vehicle stops, determining the average to be an effective data if the standard deviation of the data is within a predetermined range, and processing the averaged data as the present location data for the vehicle.

3. A device for determining a present location of a vehicle, comprising:
-
a receiving device mounted in a vehicle for receiving signals from a plurality of satellites as data; means for determining if said vehicle is stopped; means for calculating an average of a predetermined number of data received by said receiving device while said vehicle is stopped; means for determining whether a standard deviation of said predetermined number of data is less then a predetermined value; and means for controlling said receiving device to calculate a present position of said vehicle based on said average if said standard deviation is less than said predetermined value.
