Overview

Video data links carry camera footage from the aircraft to the ground in real time. Published VideoLink models use COFDM modulation, built to keep decoding through the reflections and multipath of a moving flight — see the video guide under Applications.

Long Range
Up to 50 km (LOS)
High Data Rate
Up to 80 Mbps peak
Rugged Design
Operating range -20°C to +55°C

Packing & Delivery

Video links ship as an air unit and a ground unit pair unless ordered otherwise. Packing and shipping are confirmed with the quotation.

Standard packing: air unit and ground unit in individual compartments of a shock-absorbing case, antennas and cables included.
Shipping: international express (DHL / FedEx / UPS) dispatched from China — carrier and cost quoted per order.
Lead time: quoted per order — confirm the current dispatch time for your quantity when you request a quote.
Documentation: the datasheet, user manual and configuration tool ship with the order.

FAQ

What latency can I expect?: The maximum latency is listed in the specifications above. End-to-end latency also depends on the camera and display chain — the figure is the radio-link contribution.
Why does COFDM matter for video?: COFDM keeps decoding through the reflections and multipath of a moving flight, which is exactly the condition real-time video from an aircraft has to survive.
Is the range figure guaranteed?: No — it is a line-of-sight reference value. Terrain, interference and antenna placement change the real-world figure; discount for your mission geometry.
Can one ground unit receive from several aircraft?: The supported configurations are listed in the specifications above. Describe the receiving setup you need in an RFQ and we will confirm the fit.
How do I get a quote?: Start an RFQ with this model pre-filled — we respond with pricing, lead time and documentation for the configuration you need.
