## Abstract

An ADS-B to the surface system has a modified ADS-B UAT to the surface which receives traffic and weather information from a nearby FAA ADS-B Ground Based Transceiver. The UAT to the surface sends the information to a UAT computer which then packages and sends traffic and weather data over an appropriate network to one or more remote computers. The system also has a mini ADS-B Ground Based Transceiver which provides local traffic information to the remote computer which consolidates the information with the information from the UAT computer and then sends the consolidated information to the mini ADS-B Ground Based Transceiver which transmits the information to local aircraft. The remote computer also sends local only data to the FAA over an appropriate network for inclusion in the FAA Ground Based Transceiver information.

## Claims

### Claim 1

An ADS-B to the surface system to receive local traffic and FAA GBT Traffic and rebroadcast said local traffic and said FAA GBT traffic on both 978 MHz and 1090 MHz, said system comprising a modified ADS-B UAT to the surface connected to a UAT computer which is networked with at least one remote computer which is in communication with a mini ADS-B Ground Based Transceiver (mGBT).

### Claim 2 (depends on 1)

The system of claim 1, wherein said ADS-B UAT to the surface is located within receive/transmit range of a FAA ADS-B Ground Based Transceiver (GBT).

### Claim 3 (depends on 1)

The system of claim 1, wherein said remote computer connected to said mini ADS-B Ground Based Transceiver (mGBT) is networked with said FAA Ground Based Transceiver.

### Claim 4

The method of rebroadcasting ADS-B local traffic and FAA GBT Traffic and weather, the method comprising
locating a UAT ADS-B to the surface within receiving range of an FAA Ground based Transceiver;
sending traffic and weather information received by said to the surface to a UAT computer;
packaging said weather and traffic information and sending said information to a remote computer which is in communication with a mini ADS-B Ground Based Transceiver (mGBT);
receiving local ADS-B traffic data using 978 MHz and 1090 MHz on said mini-ADS-B Ground Based Transceiver (mGBT) and providing said data to said remote computer; and
consolidating said data and eliminating duplicates and rebroadcasting the consolidated data at low power on ADS-B frequencies 978 MHz and 1090 MHz.

### Claim 5 (depends on 4)

A method as in claim 4, including transmitting a message to the FAA Ground Based Transceiver when local ADS-B traffic is not being transmitted by the FAA GBT to trigger transmitting traffic data.

### Claim 6 (depends on 4)

A method as in claim 4, wherein duplicate TIS and ADS-B traffic is eliminated by a computer system which receives, consolidates, and eliminates duplicate data.

### Claim 7

A computer algorithm to run as a service to receive ADS-B data from one or more ADS-B to the surfaces, consolidate said data once per second, eliminate duplicate data, format and send reduced ADS-B data to a transmitter to transmit on 978 MHz and 1090 MHz.
