HD45 is a stabilized camera or payload mount that controls the pointing direction of an imaging payload. Published mass is 1350 g. 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 HD45 is a stabilized electro-optical and infrared camera gimbal from Trillium Engineering of Hood River, Oregon, for small and medium unmanned aircraft. It carries a visible camera and an infrared camera on a pointing mechanism and is described by the maker as a 4.5-inch class stabilized EO/IR camera system for real-time intelligence and reconnaissance missions, built for Group 2 unmanned aircraft systems.
The HD45-LV-CZ configuration combines a global-shutter visible camera with a continuous-zoom LWIR camera. The visible camera has 1280 x 720 pixels, a field of view from 46.8 to 1.2 degrees and 40x zoom. The infrared camera has 640 x 512 pixels, a field of view from 29 to 3 degrees and 10x zoom. Continuous zoom lets the operator keep a target in the frame while changing range, and the global shutter avoids image skew on moving platforms. A laser pointer of 830 to 850 nm, Class IIIB and 50 mW, is listed among the options.
Size is 133 x 197 mm and the published weight is 1350 g, while the detailed specification lists 1375 g. The gimbal pans 360 degrees continuously and tilts from -80 to 42 degrees. Power consumption is 15 W on average and 75 W at peak, and the gimbal requires a regulated 24 V DC input. Trillium offers an external regulator in two variants, for 10 to 21 V or 17 to 34 V input with 24 V output, so the gimbal can be connected to the vehicle battery rail.
Video processing is done on board. The gimbal provides H.264 compression with adjustable bitrate, electronic stabilization, scene tracking and MISB-compliant metadata output including KLV. A GPS/INS IMU is co-located with the cameras; typical total system accuracy is 1.5 degrees, attitude, velocity and position are computed at 200 Hz, and real-time geopointing and geolocation are supported. Either the onboard GPS receiver or a platform-supplied GPS can be used, and dual GPS heading is supported. Software can be upgraded in the field.
For integration, Trillium lists a development kit with interface cable, desktop power supply and GPS antenna, recommended for all first purchases, and a retract mechanism that protects the HD40/45 during take-off and landing; it is controlled through SkyLink and powered from the same 24 V rail. Non-controlled configurations are offered without ITAR restrictions, and the company is ISO 9001 registered. Typical applications are tactical reconnaissance, surveillance, fire-line mapping and inspection from VTOL and fixed-wing unmanned aircraft.
