Advisor system and method
First Claim
1. An airport movement surface advisor system, comprising:
- a receiver, installed on a mobile first platform operating on the airport movement surface, that receives one or more signals from a signal source installed on a mobile second platform, the signals conforming to one or more types of surveillance signals;
a processor, coupled to the receiver, that processes a given signal of a given signal type from the signal source installed on the mobile second platform to produce signal data; and
a non-transitory computer-readable storage medium having encoded thereon a program of instructions, the instructions, when executed, causing the processor to;
determine a first path vector for the mobile first platform along the airport movement surface,determine a quality factor associated with the given signal, comprising;
determining a frequency of reception of multiple instances of the given signal over time to determine if an error condition exists; and
comparing latitude and longitude of a source of each of the multiple instances of the given signal to determine each of the multiple instances of the given signal originates from the mobile second platform, andbased on the quality factor, analyze the signal data from the given signal to identify a threat to the mobile first platform, comprising the processor;
determining a second path vector for the mobile second platform;
identifying the second path vector along the airport movement surface within a minimum proximity value of the first path vector; and
providing an advisory to the mobile first platform.

Abstract
An advisor system includes a computer-readable storage medium having encoded thereon a program of instructions. Execution of the instructions causes a processor to determine a current state of a first aircraft operating on a movement area of an airport including determining a path vector for the first aircraft. The path vector includes a speed and direction of travel of the first aircraft and identification of a runway intersection the first aircraft is projected to enter. The processor processes a surveillance signal transmitted from a second aircraft operating on the movement area, including determining a quality of the surveillance signal. The processor further determines a movement vector of the second aircraft, and compares the path vector and the movement vector to identify possible interference. Finally, the processor provides an advisory at the first aircraft based on the compared path vector and the movement vector.

10. A mobile runway advisor (MoRA) system comprising a non-transitory, computer-readable storage medium having encoded thereon a program of instruction that when executed by a processor cause the processor to:
-
determine a current state of a first aircraft, operating on a movement area of an airport, including determining a path vector for the first aircraft, the path vector including a speed and direction of travel of the first aircraft on the movement area; process a surveillance signal transmitted from a second aircraft operating on the movement area or on approach to land to determine a possible interference of the first aircraft by the second aircraft, comprising; determining a quality of the surveillance signal, comprising; determining a frequency of reception of multiple instances of the surveillance signal over time to determine if an error condition exists; and comparing latitude and longitude of a source of each of the multiple instances of the surveillance signal to determine each of the multiple instances of the surveillance signal originates from the second aircraft, based on the quality determination, determining a movement vector of the second aircraft, and comparing the path vector and the movement vector to identify the possible interference; and providing an advisory indicative of the possible interference at the first aircraft based on the compared path vector and the movement vector. - View Dependent Claims (11, 12, 13, 14)
