since 1090 MHz is the international standard for ADS-B Out broadcasts.

A single-band 978 MHz UAT receiver is unlikely to pick up any traffic information outside the U.S. A dual-band or 1090 MHz ADS-B In receiver will allow you to see the position of nearby ADS-B Out-equipped aircraft through air-to-air broadcast, but you will not see the positions of any non-ADS-B Out-equipped aircraft, and you will not receive any weather information. Globalįor pilots flying outside of the U.S., ADS-B In capabilities are more limited since there are no ADS-B towers that broadcast weather and traffic information. If flying with ADS-B In capabilities but no ADS-B Out, the traffic picture will not be as reliable at all times since traffic broadcasts are only provided for ADS-B Out-equipped aircraft. ADS-B In capabilities will also allow pilots to see FIS-B weather broadcasts from nearby towers. TIS-B broadcasts show the positions of nearby aircraft that are not equipped with ADS-B Out but are equipped with a Mode C capable transponder. Pilots flying with ADS-B In and Out capabilities will receive air-to-air position broadcasts from ADS-B Out equipped aircraft, and will also receive TIS-B traffic broadcasts from nearby ADS-B towers. is the only country in the world with a large network of ADS-B towers that provide ADS-B traffic and weather services, and this means that ADS-B In capabilities will be most useful in the U.S. The major sections are:Īs long as your device has an internal GPS or you have an external GPS receiver connected to it you will be able to see your location anywhere in the world, assuming your connection is strong enough.
