The SBS – Ground System monitors the received ADS-B reports to identify active ADS-B users, and the ADS-B-IN link technologies operating on the aircraft. Note: With respect to the user aircraft/vehicle (A/V) data links; ADS-B-OUT indicates the A/V can transmit ADS-B messages, ADS-B-IN indicates the A/V can receive service messages such as ADS-R and TIS-B. A dual data link equipped A/V can transmit and receive both 1090ES and UAT services. ADS-R client identification is provided by the ADS-B Report Generation, Processing, and Distribution function shown in Figure 3-10 Control Segment block and sent to the ADS-R Message Scheduling function (User Status and Validation). The identification information contained in the “User Status and Validation” message includes:
1. A/V ICAO Address 2. Link Technology Indicator In addition the ADS-B Report Generation, Processing, and Distribution function provides the A/V’s: 1. Position data 2. Altitude 3. Validation Status A/V validation status is referring to the capability of the SBS Control Station Segment providing an independent validation of the position information received in the ADS-B Messages. In certain Service Volumes, the FAA will require that the ADS-B Service provide independent validation. The validation capability may assure to a specified probability that each ADS-B Message, and the position information contained within, is from a real aircraft/vehicle with a valid position source rather than from a source broadcasting erroneous information or a spoofer. The validation methods are: 1) Comparison of ADS-B position data to radar position data, 2) Comparing a one way “passive range” with range to target indicated by ADS-B position data (available for UAT equipped targets), and 3) Use of time difference of arrival techniques. 3.1.4.2.1.3 ADS-R Target Identification The SBS – Ground System identifies all aircraft that need to receive ADS-R transmissions for each active ADS-B transmitter. It does this by maintaining a list of all active ADS-B users, and their associated input link technologies. ADS-R target identification is provided by the ADS-B Report Generation, Processing, and Distribution function shown in Figure 3-10 Control Segment block and sent to the ADS-R Message Scheduling function. The identification information is contained in the targets ADS-B- OUT messages; the ID information includes: 1. A/V ICAO Address 2. Link Technology Indicator For each transmitting ADS-B aircraft the SBS – Ground System determines all aircraft that do not have ADS-B-IN of the same link technology, that are within the vicinity, and need to receive ADS-R transmissions. © 20xx, RTCA, Inc. 53
