Global navigation satellite system landing systems and methods
First Claim
1. A method for performing instrument landings, comprising:
- receiving terrain data information from a ground-based augmentation system, the terrain data information including a height of a final approach segment above ground and a variance parameter to account for possible variations in height due to an approach over water;
determining position of an aircraft, including receiving global positioning information from a global navigation satellite system and receiving a differential global positioning, the position of the aircraft being determined from the global positioning information and the differential global positioning information;
generating altitude information of the aircraft from a radar altimeter; and
determining an aircraft altitude based on the determined position of the aircraft, received terrain data information, and the generated altitude information.

Abstract
A method and system are provided for performing satellite-supported landings in CAT II/III type landing conditions. An exemplary system includes a communication component, a positioning system, a radar altimeter, and a processor. The communication component receives terrain data information related to an instrument landing approach. The positioning system determines position of the aircraft. The radar altimeter generates altitude information of the aircraft. The processor is coupled to the communication component, the positioning system, and the radar altimeter. The processor determines an aircraft altitude based on the determined position of the aircraft, received terrain data information, and the generated altitude information.
