Tracking Antenna for Offshore Patrol Vessel

Featuring Dual-GPS, Embedded INS. Capable of Radio Frequency Acquisition and Tracking of Manned or Unmanned Surveillance Aircraft

multi-band tactical tracking antenna systems

The Mini-GS has unique features that include:

  • Dual-GPS accurate to ± 0.15° heading
  • Internal INS
  • Built-In servo drive
  • Controlled by a PC program
  • Supports PoE operation and embedded radios

The Mini-GS has been proven to provide exceptional long-range performance and relies on multi-axis, stabilized high-gain antennas that are continuously steered toward airborne or ground assets. This allows the Mini-GS to focus all its signal energy into narrow beams, thereby increasing received signal level, reducing the need for amplification and maximizing range. The Mini-GS is a highly directional antenna with narrow beamwidths to provide resistance to signal jamming and interference that plague omni antennas.

Dual-GPS with Embedded (INS)
The Mini-GS incorporates dual-GPS and embedded INS for improved accuracy, self-calibration and stand-alone positioning; heading, pitch and roll. The Mini-GS is independent of any external navigation equipment eliminating the need to connect onboard GPS or gyrocompasses. 

The Mini-GS has been tested to withstand salt/fog environments. Its ruggedized gears and tested design will withstand tough marine or ground vehicle environments.
