Multiband RF antenna to maintain connectivity in GPS-denied environments introduced by Persistent Systems

NEW YORK – Persistent Systems LLC in New York is introducing the Multi-Band Tracking Antenna to improve ground-based communications and tracking with friendly manned and unmanned aircraft -- even in the presence of electronic warfare (EW) jamming and in GPS-denied environments.

The Multi-Band Tracking Antenna can find and follow aircraft without using a satellite-based tracking system like GNSS or GPS. This capability maintains connectivity with intelligence and surveillance ISR aircraft -- even when these systems are disrupted, denied, or spoofed.

The multiband tracking antenna system can mount two MPU5 MANET radios, each operating on a different radio frequency (RF) band. When encountering interference, the system automatically switches to the band that delivers maximum performance.

The system comes with a single multi-band/multi-polarity antenna feed. There is no need to change the feed when changing RF bands-one single feed covers L-, S-, and C-Bands. The feed also has independent horizontal and vertically polarized inputs, enabling polarization diversity and maximizing MIMO (multiple-input, multiple-output) radio capacity.

The Multi-Band Tracking Antenna supports simultaneous use of an MPU5 with a third-party radio. The third-party radio benefits from the tracker's ability to operate in GPS denied environments and transmits to the platform over the same multi-band antenna feed horn.

"By operating on multiple RF bands, you can communicate through adversarial interference," says Ben Wring, senior program engineer at Persistent Systems. "Whether they deny GPS or attack our transmission directly, the system will maintain connectivity."
