Abstract
A simplified multilateration and ADS-B Surveillance System is used, to perform tagging for the FAA Low Cost Ground Surveillance program. This system may also be used as the foundation for a full multilateration system, if a customer wants to upgrade. The present invention uses just one active transmitter/receiver unit as opposed to multiple passive receivers. The present invention captures UF 5 and DF 5 data, thus providing Mode A identification, which then acts as the key to obtaining the call sign from a data fusion packages—thus making it an affordable and marketable product for small to medium-sized airports.
