US Patent:

20090153396, Jun 18, 2009
Filed:

Dec 13, 2007
Appl. No.:

11/955522
Inventors:

Thomas L. Ainsworth - Burke VA, US
Gerald Nedoluha - Bowie MD, US
Assignee:

The Government of the US, as represented by the Secretary of the Navy - Washington DC
International Classification:

G01S 1/00
US Classification:

34235712
Abstract:

A method and system for determining a bending angle and/or the presence of atmospheric ducting. An array of antennas is used in order to form an interferometer. The interferometer receives signals from GPS satellites and uses the index of infraction in order to determine a bending angle of the GPS signals and/or the presence of atmospheric ducting.

Appl. No.:

14/011114
Inventors:

Gerald Nedoluha - Bowie MD, US
Thomas L. Ainsworth - Burke VA, US
Assignee:

The Government of the US, as represented by the Secretary of the Navy - Arlington VA
International Classification:

G01S 19/53
US Classification:

34235736
Abstract:

A method and system for determining bending angle and/or the presence of atmospheric ducting on a moving vehicle, including receiving a first GPS signal from a first GPS satellite having an apparent position less than 10 degrees above the horizon; determining a true position of the first GPS satellite from information encoded in the first GPS signal; the first and second antennae receiving GPS signals from a plurality of GPS satellites located more than 15 degrees above the horizon; determining an orientation of a baseline between the first and second antennae based on a phase difference of a carrier frequency of the GPS signals from a plurality of GPS satellites positioned at least 15 degrees above the horizon; determining an apparent position of the first GPS satellite from the first GPS signal and the baseline orientation; and determining the bending angle by calculating the difference between the elevation angle of the apparent position and the elevation angle of the true position of the first GPS satellite.
