Methods and apparatus to mitigate instrument landing system overflight interference
First Claim
1. A method, comprising:
- performing, using a processor, a first measurement of a position of an aircraft relative to a first location based on an instrument landing system;
performing, using the processor, a second measurement of the position of the aircraft based on inertial measurements performed over a first time period occurring prior to the first measurement;
performing, using the processor, a third measurement of the position of the aircraft based on inertial measurements performed over a second time period greater than the first time period and occurring prior to the first measurement; and
generating, using the processor, guidance information based on a selected one of the first, second, or third measurements of the position of the aircraft.

Abstract
Systems and methods to mitigate instrument landing system (ILS) overflight interference are disclosed. An example method performing a first measurement of a position of an aircraft relative to a first location based on an instrument landing system, performing a second measurement of the position of the aircraft based on inertial measurements performed over a first time period occurring prior to the first measurement, performing a third measurement of the position of the aircraft based on inertial measurements performed over a second time period greater than the first time period and occurring prior to the first measurement, and generating guidance information based on a selected one of the first, second, or third measurements of the position of the aircraft.

12. An apparatus, comprising:
-
an instrument landing system to perform a first measurement of a position of an aircraft relative to a first location; an inertial reference unit to perform inertial measurements of a change in location of the aircraft; and a position selector to select between the first measurement, a second measurement of the position of the aircraft based on the inertial measurements over a first time period occurring prior to the first measurement, and a third measurement of the position of the aircraft based on the inertial measurements performed over a second time period greater than the first time period and occurring prior to the first measurement, and to generate guidance information based on a selected one of the first, second, or third measurements of the position of the aircraft. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A computer readable storage medium comprising machine readable instructions which, when executed, cause a processor to:
-
perform a first measurement of a position of an aircraft relative to a first location based on an instrument landing system; perform a second measurement of the position of the aircraft based on inertial measurements performed over a first time period occurring prior to the first measurement; perform a third measurement of the position of the aircraft based on inertial measurements performed over a second time period greater than the first time period and occurring prior to the first measurement; and generate guidance information based on a selected one of the first, second, or third measurements of the position of the aircraft. - View Dependent Claims (20)
