China has almost as many GBTs working as Alaska!

How many GBTs are working in Alaska today (May16, 2008)? The FAA can't tell me!

My friend Skip Nelson sent this out from China:
ADS-B Technologies is proud to announce the commissioning of its 7th Ground Broadcast Transceiver (GBT) site in China at the Badaling Great Wall Airport (40 22 34N / 115 56 27E).

Badaling GW Airport airport is located within site of the Great Wall of China and only 35 miles from downtown Beijing. It is the first privately owned General Aviation airport in China. The airport is owned and operated by the Jinggong Corporation.

Aviation Safety in Alaska: Mission Statement

To allow those in the aviation industry, regulatory agencies, educational instructors and private individuals interested in the development of Automatic Dependent Surveillance Broadcast ADS-B* technology to inform, and ferret out factual information to track the progress of its implementation in Alaska.
Those who respond to this blog will be protected by anonymity to secure that respondents are protected from retaliation by vendors to the U.S. government, the FAA, US DOT, or political interest groups.
* ADS-B – will always refer to the two-way data link technology developed by Capstone, specifically not the 1090ES version being promoted by the FAA.

Glossary:
ADS-B=Automatic Dependent Surveillance Broadcast
UAT=Universal Access Transceiver (used in Alaska) aircraft to ground, aircraft to aircraft, ground to aircraft data signals
GBT=Ground Based Transeiver-ground to aircraft data receiver, and sending unit
1090 MHz= a Ultra High Frequency used for aviation data

How does it work?

ADS-B" is an acronym that stands for:

Automatic-It's always ON and requires no operator intervention
Dependent-It depends on an accurate GNSS signal for position data
Surveillance-It provides " Real Time Radar-like" surveillance services, much like RADAR
Broadcast-It continuously broadcasts aircraft position and other data to any aircraft, or ground station equipped to receive ADS-B
