Generating High Precision Ionospheric Ground-Truth Measurements

US Patent:
7289061, Oct 30, 2007
Filed:
Jul 22, 2005
Appl. No.:
11/187244
Inventors:
Attila Komjathy - La Crescenta CA, US
Lawrence Sparks - La Crescenta CA, US
Anthony J. Mannucci - Pasadena CA, US
Assignee:
California Institute of Technology - Pasadena CA
International Classification:
G01S 5/14
US Classification:
34235702
Abstract:
A method, apparatus and article of manufacture provide ionospheric ground-truth measurements for use in a wide-area augmentation system (WAAS). Ionospheric pseudorange/code and carrier phase data as primary observables is received by a WAAS receiver. A polynomial fit is performed on the phase data that is examined to identify any cycle slips in the phase data. The phase data is then leveled. Satellite and receiver biases are obtained and applied to the leveled phase data to obtain unbiased phase-leveled ionospheric measurements that are used in a WAAS system. In addition, one of several measurements may be selected and data is output that provides information on the quality of the measurements that are used to determine corrective messages as part of the WAAS system.
