US Patent:
7683832, Mar 23, 2010
Filed:
Aug 13, 2007
Appl. No.:
11/838133
Inventors:
William G. Wright - Sandy UT, US
Assignee:
Sierra Nevada Corporation - Sparks NV
International Classification:
G01S 1/02, G01C 21/00
US Classification:
34235712, 34235706, 34235715
Abstract:
A method of calculating position data for an airborne aircraft using a GPS-based airborne navigation system includes the processing of a position component of a relative state function by fusing a plurality of different types of measurement data available in the GPS-based system into a weighted least squares algorithm to determine an appropriate covariance matrix for the plurality of different types of measurement data.
