High reliability sensor system for fast steering mirror control

The Measuring Division of Kaman Precision Products’ KD-5100+ high-reliability differential displacement measurement system has nanometre resolution. 

With its stable design, extremely small size, and low power consumption, the KD-5100+ is suitable for laser communications satellites and ground stations, image stabilisation systems, and directed energy systems for ground, shipboard and airborne applications.

The KD-5100+ is an upgraded, higher reliability version of Kaman’s proven KD-5100 measuring system and utilises the identical proprietary hybrid microcircuit. The KD-5100+ incorporates upgrades to the circuit layout, ground connections, and sensor connectors, and adds higher reliability diodes and capacitors.

Featuring a small package size – only 2 x 2.12 x 0.75 inches thick – the KD-5100+ is an ideal solution for meeting SWaP-C requirements. It is manufactured to Mil-PRF-38534 Class H, with MIL-SPEC components used throughout the electronics. The KD-5100+ features a mean time between failures exceeding 238,000 hours in a space flight environment and 55,000 hours in a tactical environment. Kaman also offers the DIT-5200, a commercial version of the KD-5100+ for applications where mil-spec requirements, size, weight and power consumption are less critical.
