Replacing the older HD50 model, the HD55 houses sharper EO and IR cameras for better target identification

Trillium Engineering, an industry leader in gimbal camera systems for small unmanned aircraft systems (UAS), today announced that it has begun flight testing of its lightweight HD55 system and High Definition.

Designed for use on Group 2 and smaller Group 3 UASs, the new HD55 uses electro-optical (EO) and cryogenically cooled (MWIR) medium wave infrared cameras, as well as an integrated image processor – all in a gimbal only 5.5 inches in diameter and weighing 1750 grams.

“At Trillium, we are constantly on the lookout for cutting edge technology,” said Rob Gilchrist, Co-Founder and President of Trillium Engineering, “and the development of the HD55, the newest addition to our family of gimbal systems, illustrates this approach. .

The HD55 replaces the end-of-life HD50, available in four configurations and first delivered to customers in November 2014. The HD50-MV was the smallest cooled MWIR gimbal camera system on the market.

The new improved HD55 will have the same swept volume as its predecessor, but will be slightly lighter and more capable than the pioneer HD50. “The HD55 has a narrower field of view than the HD50, which allows the new system to have a closer and more actionable look at targets,” said Gilchrist.

Trillium personnel have flight tested the HD55 on a variety of airborne platforms, including a small multi-rotor drone and a manned Cessna aircraft, which serves as a substitute for a tactical fixed-wing UAS. The next step, say company officials, is to start testing on the real thing.

“We are already attracting interest from major platform vendors,” said Gilchrist.
