Stratus 3 by Appareo is the latest generation of the premier ADS-B receiver. Now available for use with OzRunways, Stratus 3 provides highly sensitive 1090 ADS-B reception, an accurate external GPS receiver, and even an AHRS with gyroscopes and accelerometers to provide a backup attitude indicator on your iPad.
What's more, Stratus 3 has the ability to use external GPS and ADS-B antennas allowing the unit to be installed out of sight and still provide the best reception.
