Determining A Predicted Performance Of A Navigation System

View page
US Patent:
7423582, Sep 9, 2008
Filed:
Dec 15, 2005
Appl. No.:
11/305172
Inventors:
James E. Holderle - Aliso Viejo CA, US
James A. Keebaugh - Diamond Bar CA, US
Jeffrey W. Lewellen - West Covina CA, US
Assignee:
Raytheon Company - Waltham MA
International Classification:
G01S 1/00
US Classification:
34235702, 34235715
Abstract:
In one aspect, a method for determining a predicted performance of a navigation augmentation system includes determining a normal performance of the navigation augmentation system and determining a predicted performance of the navigation augmentation system based on determining the normal performance. In another aspect, a system for determining a predicted performance of a navigation augmentation system includes a long-term monitor for determining a normal performance of the navigation augmentation system and a short-term monitor for determining a predicted performance of the navigation augmentation system based on the normal performance of the navigation augmentation system.

Determining Usability Of A Navigation Augmentation System

US Patent:
7365678, Apr 29, 2008
Filed:
Nov 30, 2005
Appl. No.:
11/290613
Inventors:
David R. Heine - Fullerton CA, US
Thomas D. Springsteen - Diamond Bar CA, US
Jeffrey W. Lewellen - West Covina CA, US
Walter M. Golonka - Diamond Bar CA, US
Assignee:
Raytheon Company - Waltham MA
International Classification:
G01S 5/14
US Classification:
34235702, 34235703
Abstract:
In one aspect, the invention is the system for assessing a navigation augmentation environment. The system includes a reference station for receiving messages from a satellite. The reference station has a known position. The system also includes a simulator for simulating an augmentation system by determining corrections based on the messages received and the known position of the reference station. The system further includes a monitoring system to render the corrections to a user in a form enabling determination of the usability of the augmentation system in the navigation augmentation environment.
