MicroLink® SDR

Software Defined Radio - Mission Payload Controller with Tracking Software

Frequency division duplex – dual-stream, DVB-T COFDM | OFDM data link radio and remote controller. Supercomputer accelerated video processing with multi-stream capability.

MicroLink® is a software defined, FDD transceiver and mission payload controller. Operating in frequencies from 1.2 GHz to 7 GHz, MicroLink® can automatically adapt DVB-T modulation schemes to maximize range or bit rate based on mission parameters, presets or operator inputs. High-speed Microlink® provides dual video transport streams with transmission bandwidths ranging from 2MHz to 16MHz at up to 40 Mbps.

MicroLink® connects to any 11-32 VDC power bus and provides a 250W power management system that regulates power to 12VDC and 28VDC outputs. These regulated outputs provide monitoring and control of each transmission payload independently. Software defined circuit-breakers are also included to protect these payloads and other sensitive equipment connected through MicroLink®.

Video-Audio-Data Management:
Troll’s proprietary software controls multiple transport streams to process audio, video, and sensor data. MicroLink® can encode up to three independent HD video inputs to 4k HEVC 265 4:2:2, H264, MPEG-2 or MJPEG. One or more of these transport streams can be transmitted to the ground while recording each stream to an on-board DVR. This allows time delay video playback in the air and adjustable downlink transmit resolutions to support real-time exploitation on the ground.

Software Defined Video Processing:
Our image processing software includes image stabilization, image tracking, ROI, image fusion and many other capabilities.

Supercomputer Module
MicroLink® provides a 64-bit, low-power, high-performance Nvidia supercomputer that accelerates video encoding, decoding, encryption and control. Its energy-efficient Arm cores provide access to over one teraflop of system processing capacity with unimaginable speed and performance on less than 15W of total system power.

Ethernet Switch and Router
The MicroLink® also incorporates a fully managed 100/1000 Ethernet switch and router. This provides a network managed hub that connects to onboard payloads for monitoring, control, diagnostics and test.
