Persistent Aerial Surveillance

The only tactical aerostat system in the world with onboard helium recovery and purification.

  • Fully Self-Contained Aerostat Launch Vehicle
  • Tactically Mobile (can be relocated while fully inflated)
  • Remote Control  of Cameras, Sensors and RF Equipment
  • 75lbs (34kg) Payload Capacity
  • Only 4 Person Crew Required
  • RF Communications and Repeater Options

Troll’s long endurance Aerostat system is designed to receive, monitor, record and transmit HD video, voice and data to the limits of Line of Sight (LOS).

Real-time video and data is transmitted and received over a secure high-speed data link in multiple frequencies from 300 Mhz to 15 GHz. The payload can be customized to support a variety of sensors, microwave repeater and control options to fufill unique mission requirements.

The balloon system includes a multi-sensor camera, intuitive touchscreen control software, transmission and reception system for audio, video and data. The imagery can be controlled, recorded and viewed from the launcher, via a wireless link to a distance of up to 25 miles or at a command center anywhere in the world.

Troll's SkyLink Mini is ideal for rotor-craft, high-speed turboprops or very light jets, 
used for airborne ISR.

Why Choose Directional Data Links?

As the demand for Radio Frequency (RF) spectrum grows, many areas of the world are already saturated with RF transmitters that cause widespread interference with one another.  In the future, the assignment of radio frequency spectrum may require a system that prioritizes national, international and global allocation or distribution that limit the available microwave frequencies creating an increasing potential for congestion in the available spectrum. 

Troll Systems’ airborne and ground high-gain tracking antennas and radio frequency ground stations are designed to manage spectrum efficiently. The technologies we deploy are well suited to a future where spectrum management is likely to be required for military, civil and commercial interests.

1. Narrow Directional Bandwidths

  • Are resistant to interference and jamming
  • Require less power to transmit to the radio horizon.
  • Improve spectrum management in crowded RF environments, leading to better frequency availability.

2. Antenna Signal Radiation Patterns Directional vs. Omni

  • Omni antennas radiate RF energy in every direction, making frequency availability and / or reallocation difficult in concentrated RF environments.
  • Omni antenna radiation patterns are easy to locate, jam and interfere with in operational environments.   
  • To increase range, omni antennas generally require more power leading to more heat, weight and spectrum inefficiency.

Designed to simplify the integration of third-party equipment, Troll’s Linkbox makes it easy to customize your data link and provide inputs and outputs for all your gear with a quick and easy hook-up. 

The Link Box can be set up to transmit and receive simultaneously.  It includes transmitters, receivers, power amplifiers, filters, switches and HD/SD encoders along with other video or data link equipment that will accommodate all downlink requirements in a single, easy to connect package.  Depending on the system configuration, other add-on equipment for the LinkBox may include switchers, filters, splitters, receivers, decoders, video processors, and more.

Control and monitoring of the Linkbox is typically achieved via Troll Systems' C100 controller which allows the operator to have full control of each of the linkbox's internal components as well as change and reconfigure the Linkbox and system parameters as required. The C100 controller's touch screen provides a scrolling map screen that allows the operator to enter receive station locations and presets.
Any type of video or data format can be input into the Linkbox and connected to the antenna and transmission system.  This articulate design enables the Linkbox to encode any video or data to ASI or other types of compression formats as required, and then feed it to the antenna for transmission.  The incoming RF signal is input to the Linkbox receiver component for decoding and data output.  The usable data input and outputs include Serial, Ethernet, HDMI or HD/SD video.
 Linkbox connections:

  • Power in: XLR 4 +28VDC & +12VDC
  • Connections: DB9, RS485, Ethernet, N-type RF connectors, HDMI
  • Video in/out: BNC
  • ARINC 429: DB9 Male, (From aircraft)
  • Ethernet: RJ45

Security threats to individuals and nations are increasing in both frequency and intensity.  Airborne video surveillance has become a vital tool in securing peace, protecting borders, and providing situational awareness to every tactical level. 

Troll Systems is committed to providing affordable, easy to deploy bidirectional communication systems that provide long-range, high-bitrate surveillance capability.

These systems can automatically track, transmit and receive in any modulation scheme required.

Troll's systems have been successfully deployed for the US Army, prime military contractors, commercial broadcast and law enforcement agencies around the world.
