Offerors must disclose any proposed use of foreign nationals (FNs), their country(ies) of origin, the type of visa or work permit possessed, and the statement of work (SOW) tasks intended for accomplishment by the FN(s) in accordance with section 3.5 of the Announcement. Offerors are advised foreign nationals proposed to perform on this topic may be restricted due to the technical data under US Export Control Laws. Develop a low cost, size, weight, and power (C-SWaP) environmentally sealed pointing and stabilization solution for infrared search and track (IRST) payload for Group 2/3 unmanned aerial systems (UAS) to support detection and tracking of small UAS (sUAS) at extended range. Description: Small UAS (sUAS) pose a threat to both deployed U.S. forces and military bases. Traditional methods for detection, tracking and identification include acoustics, radio frequency (RF) and infrared (IR) cameras, which tend to be deployed from ground sites [1]. Airborne sensors can supplement these ground systems by providing forward-deployed surveillance and/or terrain relief. Current state-of-the-art (SoA) IRST sensors have been developed for use on large platforms (e.g., fighters, bombers, group 4/5 UAS) to support detection and tracking against similar large platforms. Similar design concepts would be applicable for group 2/3 UAS, but at significantly reduced C-SWaP. Many commercial-of-the-shelf (COTS) gimbals exist for group 2/3 UAS that are equipped with IR payloads, typically midwave infrared (MWIR) or uncooled longwave infrared cameras (LWIR) [2]. However, the IR payloads are typically optimized for surface surveillance missions, which prioritize spatial resolution and generally only provide two axis pointing & stabilization [3]. The third axis, roll, is uncompensated and dependent on how steady the UAS can fly. Uncompensated roll will degrade IRST performance and increase computational burden to remove motion artifacts. This effort seeks a three-axis stabilized sealed IRST payload to handle directional pointing and pitch/roll/yaw stabilization suitable for use on Group 2/3 UAS. Sealed refers to an IP54 rating to keep the optomechanical pointing/stabilization and sensor protected against dust and water [4]. The sealed system shall compensate for UAV motion due to gusts, turbulence, and platform jitter. This effort will include both hardware and software approaches to provide a complete pointing and stabilization sealed payload package. An off-the-shelf gimbal or mature prototype is expected to be used as a starting point for the design. The sealed system shall provide the raw sensor data at 60 frames per second over Ethernet, command and control of the sensor, provide accurate line-of-sight pointing data, and on-gimbal inertial measurement.
