Methods And Systems For Maintaining A Position During Hovering Operations
US Patent:
7248208, Jul 24, 2007
Filed:
Jun 10, 2004
Appl. No.:
10/865407
Inventors:
James R. Hager - Golden Valley MN, US
David V. Hansen - Eden Prairie MN, US

Assignee:
Honeywell International Inc. - Morristown NJ
International Classification:
G01S 13/08
US Classification:
342120, 342 63, 342109, 342 99, 342121, 342192, 701 11
Abstract:
A method for maintaining a position of a hovering vehicle that incorporates a radar altimeter is described. The method includes receiving signals at the radar altimeter based on a change of horizontal direction, operating the radar altimeter to generate a Doppler frequency spectrum based on the received signals, and determining a change in vehicle direction and velocity which will reduce a width of the Doppler frequency spectrum of the received signals. A radar altimeter which generates the Doppler frequency spectrum is also described.
Adaptive Filtering For Altimeters
US Patent:
7725220, May 25, 2010
Filed:
Aug 24, 2006
Appl. No.:
11/466819
Inventors:
Curtis J. Petrich - Minneapolis MN, US
David V. Hansen - Eden Prairie MN, US
David V. Hansen - Eden Prairie MN, US
Assignee:
Honeywell International Inc. - Morristown NJ
International Classification:
G01C 23/00
US Classification:
701 4, 701 10
Abstract:
A method of processing altitude measurements for an aircraft is disclosed. The method involves filtering raw altimeter data within an altimeter to substantially limit random variations in the altitude measurements for one or more altimeter measurement profiles.
