High-Speed Laser Communication with Fast Steering Mirrors for Precise Beam Control Applications such as global internet coverage and Earth observation are driving the rapid growth of LEO satellite constellations. Traditional radio frequency communication can’t provide high data rates, low latency, and secure intersatellite links. Free-space optical communication meets these requirements by transmitting data through an extremely narrow laser beam. However, maintaining optical links in LEO is extremely challenging: • Satellites move at velocities of several kilometers per second while communicating across distances of hundreds to several thousand kilometers • Reliable laser communication depends on flawless pointing, acquisition, and tracking (PAT), requiring systems that react instantly and keep the beam precisely aligned throughout link acquisition and operation So how does PI enable next-gen satellite networks?
