Mini GS

Fully Weatherized, High-Gain c2isr Tracking Antenna

Available in up to four frequency bands UHF to Ku. Suitable for fast moving terrestrial vehicles and on-the-move tacking operations. FDD - CDLs, BE-CDL, COFDM, MANET / MIMO

Following the success of Troll’s airborne Mini, the MiniGS was built for rugged terrain and demanding maritime applications. These highly directional, long-range tracking antennas support a variety of secure radio waveforms and network topologies commonly used for security and defense applications.

One of many of our intelligent tracking antennas, the MiniGS incorporates an edge-computing processor that enables customers to directly control the Mini GS.  This eliminates the need for Troll’s PCC remote control application. With a powerful computer onboard Troll’s tracking software and 3rd party radio applications can deliver high capacity, long range transmission with lower latency, improved reliability, stability and interoperability with customer furnished equipment.

MiniGS incorporates an advanced dual-GSP (DGPS) and dynamic INS which automatically aligns the antenna to North within 0.15° accuracy on both stationary and moving vehicles. Unlike other systems which rely on external heading sources, or unreliable magnetometers, the MiniGS uses its advanced DGPS and embedded INS to continuously solve for heading. This system takes advantage of the latest in global navigation with its 72 channel GNSS receiver capable of simultaneously tracking multiple constellations. Various tracking solutions are provided, including Troll’s patented RF tracking, GNSS and MISB data (radio link dependent).

The Mini GS has deployed in harsh conditions and in contested operational areas where it has been highly effective. In US Army field tests the Mini GS outperformed its peers, gaining industry wide attention for its GPS denied tracking technologies’. Driven by Cyclops, the ground system can automatically establish high-bit-rate data links and defend them at long range and in noisy radio landscapes.

The MiniGS has unique features that include:

  • Dual-GPS accurate to 0.15°heading
  • Internal INS
  • Built-in servo drive
  • Controlled remotely or via 3rd party transceiver applications
  • Suitable for salt/fog environments
  • Supports PoE operation and embedded radios
  • Transmit and receive in up to four discrete frequencies with a variety of filtering options
  • Quick-connecting active and passive modules

The exceptional long-range performance of the Mini-GS relies on multi-axis, stabilized high-gain antennas that are continuously steered toward airborne or ground assets. This allows the MiniGS to focus all its signal energy reducing the need for amplification to maximize range. The MiniGS’s narrow beam width also provides an obstacle to signal jamming and interference often associated with omnidirectional antennas or saturated radio frequency environments.

Dual-GPS with Embedded (INS)
The MiniGS incorporates dual-GPS and embedded INS for improved accuracy, self-calibration and stand-alone positioning, heading, pitch and roll. Self-contained, the MiniGS is independent of any external navigation equipment. This eliminates the need to connect onboard GPS or gyrocompasses reducing cost and complexity of installation.

The MiniGS incorporates ruggedized gears and chemically resistant materials to withstand ground vehicle and marine environments.
