A21 GPS Antenna

Hemisphere GPS has released the A21 Antenna. Agricultural vehicles and equipment, including aircraft, typically generate electrical "noise" and interference which can compromise the performance of an antenna. The A21 antenna is designed to maintain its tracking of GPS and differential correction signals in these types of environments, and in high-dynamic applications where the antenna may be turned on its side.  

The A21 antenna will begin shipping in May 2009, and will be included in all Hemisphere GPS Air M3, Flying Flagman, and LiteStar II^TM GPS guidance systems. Current Hemisphere GPS Air GLA-3 antenna owners can also upgrade to the new A21 antenna. The A21 antenna features the same mounting footprint as previous Hemisphere GPS Air antennas. The A21 antenna technology will soon be featured in other Hemisphere GPS product lines as well.
