Redundant Determination of Positional Data for an Automatic Landing System
First Claim
1. An automatic landing system for an aircraft, comprising:
- a control device configured to provide positional data for controlling the aircraft;
a first position or range measuring device configured to detect first positional data of the aircraft;
a second position or range measuring device configured to detect second positional data of the aircraft; and
a sensor device configured to detect sensor data from which at least one of a direction in which a landmark is located and a range of the landmark to the aircraft can be determined,wherein the control device is configured to generate a first hypothesis for the determined direction or range of the landmark on the basis of the first positional data and a second hypothesis for the determined direction or range of the landmark on the basis of the second positional data,wherein the control device is configured to either confirm or discard the first hypothesis and the second hypothesis, respectively, using the sensor data detected by the sensor device, andwherein the control device is configured to determine that only positional data, on which a confirmed hypothesis is based, is to be used to control the aircraft.

Abstract
An automatic landing system contains a control device for providing positional data for controlling an aircraft, a first position or range measuring device for detecting first positional data of the aircraft, a second position or range measuring device for detecting second positional data of the aircraft, and a sensor device for detecting sensor data from which a direction in which a landmark is located and/or a distance of the landmark to the aircraft can be determined. The control device may be configured to generate, based on the first positional data, a first hypothesis for the direction and distance of the landmark and, based on the second positional data, a second hypothesis for the direction and distance of the landmark. Moreover, the control device may be configure to confirm or discard the first hypothesis and the second hypothesis, respectively, using the sensor data detected by the sensor device.

20. A method for determining positional data of an aircraft for an automatic landing system of the aircraft, the method comprising the steps:
-
detecting, by a first position or range measuring device of the landing system, first positional data of the aircraft; detecting, by a second position or range measuring device of the landing system, second positional data of the aircraft; detecting, by a sensor device of the landing system, sensor data from which at least one of a direction in which a landmark is located and a range of the landmark to the aircraft can be determined; generating, by a control unit of the landing system, a first hypothesis for the determined direction or range of the landmark based on the first positional data; generating, by the control unit, a second hypothesis for the determined direction or range of the landmark based on the second positional data; confirming or discarding, by the control unit, the first hypothesis and the second hypothesis, respectively, on the basis of the sensor data detected by the sensor device; and determining, by the control unit, that only positional data, on which a confirmed hypothesis is based, is to be used to control the aircraft.
