HD25 is a stabilized camera or payload mount that controls the pointing direction of an imaging payload. It forms part of an observation payload, linking the sensor line of sight with the mounting, power and control interfaces of the host platform.
The Trillium HD25 is a stabilized camera and payload gimbal from Trillium Engineering, designed as a low size, weight, power and cost camera system for Group 1 and Group 2 unmanned aircraft. It points an imaging payload at a target and holds the line of sight steady while the aircraft moves. Two configurations exist: the HD25-XV with a visible camera and the HD25-LV with a visible and a long-wave infrared (LWIR) camera.
The gimbal is meant for observation, tracking and geolocation missions on small UAS, including systems of the launched effects type. Embedded video processing provides electronic stabilization and scene tracking, and optional target tracking is available with an external module. The system is environmentally sealed against dust and water, and non-controlled, ITAR-free configurations are offered.
The main figures are these. Pan is 360 degrees continuous and tilt covers -80 to 42 degrees, with an encoder resolution of 0.02 degrees. The visible camera has 1280 x 720 pixels with a field of view from 13.7 to 4.6 degrees and 8X zoom, digital zoom included. The LWIR camera of the LV version has 640 x 512 pixels, a 24.1 degree field of view and 4X zoom. Mass is 340 g for the XV and 350 g for the LV, and both measure 71 x 109 mm (W x H). An IMU is co-located with the cameras, and typical total system accuracy is 1.5 degrees, which supports real-time geopointing and geolocation.
Integration is through Ethernet or serial control. Electrical power is a regulated 24 VDC input, with external regulation accepting 10 V to 30 V available, and consumption is 10 W average and 75 W peak. The video pipeline is digital: onboard H.264 compression with adjustable bitrate, with analog video also available, and MISB-compliant output with embedded KLV metadata. A GPS receiver is on board, or the GPS of the platform can be used. Software can be upgraded in the field.
Typical applications are intelligence, surveillance and reconnaissance, target tracking and geolocation from small fixed-wing and rotary-wing UAS.

For tactical UAS, two new HD59 variants from Trillium Engineering, the HD59-MVV-C and the HD59-MLVV-C, pair MWIR imaging with a built-in laser rangefinder and laser pointer. Trillium puts system cost more than 30 percent below traditional…
Trillium Engineering says its HD80-MLVS-LD-LRF-LP gimbal flew on a Textron Systems Aerosonde UAS during a Taiwan Army first: a manned-unmanned teaming (MUM-T) operation that worked. The Aerosonde teamed with an AH-64E Apache in the Divine…
Trillium Engineering switches its gimbal software from calendar versioning to the X.Y.Z semantic scheme, beginning with release 3.1. The change lets customers judge the scope of each update from its number.
