1. A method comprising:
- transmitting a Mode S interrogation;
receiving a response from an aircraft that has received the Mode S interrogation;
determining a range to the aircraft based on a time period between transmitting the Mode S interrogation and receiving the response;
requesting information from one or more data sources, wherein the requesting includes specifying that the information should only be provided by the one or more data sources if the aircraft is within a predetermined volume;
receiving the information from the one or more data sources; and
determining at least one of a bearing to the aircraft and a position of the aircraft using the determined range and the information from the one or more data sources.

Abstract
A method according to the present invention includes transmitting a Mode S interrogation and receiving a response from an aircraft that has received the Mode S interrogation. A range to the aircraft is determined based on a time period between transmitting the Mode S interrogation and receiving the response. The method further includes receiving information from one or more data sources and determining at least one of a bearing to the aircraft and a position of the aircraft using the determined range and the information from the one or more data sources. Information can be received from any number (or type) of data sources, such as ADS-B-equipped aircraft.

8. A system comprising:
-
a processor; a Mode S transceiver; a data transceiver; and a memory coupled to the processor and storing instructions that, when executed by the processor, cause the processor to; transmit a Mode S interrogation using the Mode S transceiver; receive a response through the Mode S transceiver from an aircraft that has received the Mode S interrogation; determine a range to the aircraft based on a time period between transmitting the Mode S interrogation and receiving the response; request information from one or more data sources, wherein the requesting includes specifying that the information should only be provided by the one or more data sources if the aircraft is within a predetermined volume; receive the information from the one or more data sources through the data transceiver; and determine at least one of a bearing to the aircraft and a position of the aircraft using the determined range and the information from the one or more data sources. - View Dependent Claims (9, 10, 11, 12)
