PI offers fast steering mirrors for satellite communication links
Physik Instrumente (PI) has introduced fast steering mirrors (FSMs) designed for free-space optical communication (FSOC). These components are crucial for next-generation Low Earth Orbit (LEO) satellite constellations requiring precise laser beam control.
Shrewsbury, Massachusetts – Physik Instrumente (PI), a global leader in precision motion control, has launched advanced piezo-driven and voice-coil-driven fast steering mirrors (FSMs) engineered for free-space optical communication (FSOC). These FSMs are vital for the expanding Low Earth Orbit (LEO) satellite constellations, which depend on precise laser beam steering to maintain global internet connectivity.
The company’s FSM technology provides nanoradian-range angular resolution and kilohertz-range mechanical bandwidths. These capabilities are essential for maintaining stable optical links over distances of hundreds to thousands of kilometers between satellites, aircraft, and ground stations, enabling higher data rates, reduced latency, and lower power consumption compared to traditional radio frequency communications.
PI states that its FSMs are already operational in commercial LEO communication satellites and other space missions, with performance validated in harsh space environments. The company supports high-volume production of standard and custom solutions for FSOC applications, complemented by advanced motion controllers and beam acquisition/tracking algorithms designed to accelerate optical link establishment.
The technology utilizes frictionless flexure-guided mechanisms, eliminating backlash and wear for long-term reliability. PI offers its FSM solutions as standard products and custom OEM components for various industries, including photonics, laser processing, and image stabilization.
