Pulse Space is an aerospace technology firm specializing in advanced laser-based communication and power transfer systems for space and high-altitude applications. With deep expertise in high-efficiency optical platforms, our team is well-positioned to support the DoDs need for resilient directed energy solutions in contested environments. In response to Space Force SBIR topic SF 254-D801, Pulse Space proposes a scalable satellite-based optical relay network to enhance MILSATCOM resiliency. Our high-power laser systems enable long-range, precise beam transmission, overcoming challenges like atmospheric turbulence, platform constraints, and weather. The proposed LEO constellation will support secure, high-bandwidth optical communication and energy delivery, capable of transmitting 29.7 kW to a 3-meter target from 1,000 km. The network will offer low-latency, high-throughput inter-satellite links and reliable connectivity for ground stations and airborne assets. Pulse Space proposes a resilient network of Low Earth Orbit (LEO) satellites equipped with high-power lasers for secure, high-bandwidth optical communications and energy delivery. Designed to operate in contested environments, including adverse weather conditions, the system enables reliable links between ground stations, high-altitude drones, and other assets. The overall objective is to deploy a constellation of satellites that can each deliver 29.7 kW of optical power to a 3-meter target area at 1,000 kilometers, significantly extending communication range and improving resilience against atmospheric interference and jamming with low-latency and high-throughput inter-satellite optical links. The objective of this effort is to develop, demonstrate, and validate a high-efficiency, resilient optical relay system capable of supporting ground-to-air laser power transmission. The system will achieve 80% optical throughput efficiency and maintain beam jitter below 20 µrad. It will interface with ground-based lasers up to 20 kW and relay energy through space-based platforms to bypass surface-layer atmospheric turbulence. Additionally, the system will support redundant, resilient network operations by integrating with military satellite communication systems such as MUOS, enabling continued function in GPS-denied or contested electromagnetic environments. The expected outcome of this Phase II effort is a validated 1/4-scale ground-based demonstration brassboard integrated with a c-sUAS laser.
