"CHINA PIONEERS IN ADS-B TECHNOLOGY"
- The first live 978 MHz air-to-ground demonstration outside the U.S. took place at Guanghan, China on 15 July, 2005
- The Civil Aviation Flight University of China now has more than 150 training aircraft equipped with ADS-B
- Seven GBT's will cover the University's training areas in Sichuan and Henan Provinces

"SATELLITE-ENABLED ATM USING ADS-B"
Wherein both Ground Based Tranceivers (GBT's) and satellite connectivity are used within the same system.
- Satellite connectivity is Primary in remote / oceanic areas
- GBT's are primary in known satellite "shadow" areas
- GBT's supplement satellite connectivity where redundancy and/or additional reliability is needed (ie; Terminal Areas)

"ACTUAL TIS-B DISPLAYS"
Actual CAPSTONE TIS-B displays as seen over Cook Inlet, Anchorage, Alaska, March 2004.
- TIS-B (Terminal Information Service-Broadcast) re-broadcasts ATC radar targets in a format compatible with ADS-B traffic displays.
- Targets may be displayed in either "relative", or "barometric" altitude
- Target information, including range, speed, altitude and relative position "clock codes" are repeated on a detailed text page
- TIS-B gives a CAPSTONE equipped aircraft all the advantages of TCAS within a participating ATC environment

"ADS-B IN THE PACIFIC"
A "Capstone-like" program wherein ADS-B is deployed between the Republic of Palau and the Northern Mariana Islands would dramatically improve safety, while at the same time providing another unique (ie; oceanic) environment for further evaluation of this new technology.
- Initially, four GBT's would provide more than 360,000 sq miles of ADS-B services for aircraft flying between Saipan and the Philippines and between Asia and the South Pacific.
- A prototype ADS-B - only ATM system could be developed at Babeldaob, Yap, or Saipan to develope policies and procedures for deployment throughout the Pacific.
- Eventually - perhaps in as little as 2-3 years - satellite communications enabled ADS-B could cover the entire Pacific.
- FIS and real-time weather radar data would be available to aircraft at far greater distances.
- ADS-B is a uniquely effective SAR tool at sea, where conventional EPIRB's sometimes sink with the wreckage.
- Commercial operators could follow their flights in near-real time, using simple Internet tools.
- During initial evaluation, threshold equipage could be as little as two GBT locations and 4-6 aircraft.
