I was reading an article in Air and Space Magazine about this new system that will supposedly replace radar.
The system will take location information from a GPS or other Navigation system and broadcast it to ground stations and other airplanes, giving them a picture of where traffic is in the sky. controlling agencies would use the ground sites for information to operate the current STARS displays. The pros of this new system is much lower separation and increased capacity. The system will also have some form of TCAS on it to help avoid mid air collisions.
I am curious if any of you have heard about this and what your thoughts are on the matter?

As someone with many hours of actually using it, I can say that I certainly hope it replaces radar... The features of the system are simply outstanding and very easy to use...

From what I've heard, it is very popular in Alaska. Embry-Riddle has it installed in most of its aircraft and it's certainly a great tool, being able to pick up traffic and place weather overlays, etc.

ADS-B is in use in many parts of the world, particularly Northern Europe, Australia and is being trialed in parts of the USA.
The aircraft transmits (or "squits") a repeating signal and can also be interrogated. The aircraft basically transmits a hex code (a mix of 6 letters and numbers) which is unique to the aircraft. This identifies to a receiver that the aircraft is in range of the receiving stations. Aircraft can transmit a range of information including position, height, speed, flight number and reg (the reg also ties to the hex).
It will be possible to transmit the info via satellite link in time. When aircraft transmit position it is possible, by link to a computer, to produce a radar like display which is totally usable for ATC purposes and, for the first time, using satellite links will be able to give a picture of aircraft positions over areas where there is no radar.
Roll out around the world will depend on governments and international agreements but the equipment on board basically exists and needs a simple extra "box" to transmit and, on the ground, for line of sight reception all that is needed is a simple aerial, for satellite reception a receiving link - far cheaper and less vulnerable than radar.
In SW Ireland my SBS-1 is currently showing around 700 individual aircraft a day using ADS-B of which around a third are transmitting position and showing as a target on my screen. In the UK the usage is much heavier.

From the sound of the article this seemed like a new piece of equipment but by the sounds of it, it has been around for a while, a year atleast. So how many people out there use it and how many people have yet to get it, does anyone have those facts.

ADS-B has been in existence for a good number of years and is being trialed in various areas to various levels of intensity.
ALL aircraft operating in the London TMA, and soon all of the London ATC area, MUST carry ADS-B.
Other areas around the world have their own test areas - significantly the FAA have lagged on this but now seem to be committed to the system for eventual US wide implementation. It would certainly assist with the Free Flight programme.
If you read both articles, you will notice that the system is operational in Australia, over the remote areas where there is no radar coverage.
As for Canada, NavCanada wants to deploy ADS-B in Northern Canada, to provide surveillance and communications in the 250,000 square nautical miles of airspace over Hudson Bay, where there is no radar coverage at the moment.

us Air Traffic Controllers have a good record, we haven't left one up there yet !!

IMO you won't find anything close to a free flight program in the States until there are severe reductions in the antique separation standards and having a performance based NAS along with ADS-B.

do you think it will ever happen that they will allow aircraft to be closer. i know that some seperation is do to the wake that they leave, but also some is do to the limitations in radar
