N203 Series Conformal GPS CRPA

It is designed to receive right-hand circularly polarized (RHCP) radiated signals from Navstar GPS satellites and couple the radio frequency signal to the antenna electronics (supplied by others) via SMA or equivalent connectors. The multi-element array is used to adaptively steer nulls or point beams in the presence of interfering jamming signals.

Microstrip patch type radiators provide a low-profile package. A hybrid feed incorporated in each element allows operation over a wide temperature band without the temperature-induced detuning often associated with such patch elements. This technology can be used for platforms such as unmanned aerial systems, helicopters, land vehicles and high-performance missiles and munitions.
