Introduced more than a decade ago by the FAA, ADS-B (Automatic Dependent Surveillance-Brodcast) provides weather and traffic information to all aircraft equipped with an ADS-B receiver, such as the XGPS170, subscription-free. The portable XGPS170 ADS-B receiver provides ADS-B weather and traffic broadcasts, to a variety of compatible EFB apps (Sold Separately), for display on your iPad.
An external GPS is one of the most important accessories to use with your iPad and the iPad Sport™ or iPad Kneeboard Pro™. Together, your iPad is secure, viewable and always connected to a GPS signal during all phases of flight. How useful is it to glance down at your iPad expecting to instantly see your position on the map or approach plate only to find that the signal was lost?
The advantage of the Dual XGPS170 is that it connects wirelessly to the iPad, iPhone, or iTouch using Bluetooth. It can be placed where ever you wish with no wires or anything plugged into the iPad itself.
An external GPS is REQUIRED even if your iPad has the A-GPS chip as found in the 3G models. Why? Because the A-GPS in the iPad has proven to be unreliable for many pilots. Pilots report loss of GPS signal in the air, an inability to acquire or re-acquire a GPS signal once in the air, or periods of time where no GPS signal is present.
An external GPS is ESSENTIAL when your iPad does not have a GPS (when a 3G version is not purchased). Why? Because the WiFi iPad version does not have any GPS at all.
