SoftBank Corp.'s ground team tracked Sceye's stratospheric platform in real time and continuously received reflected laser signals, advancing future free - space optical (FSO) communications between ground, stratosphere, and space MORIARTY, N.M., Sept. 23, 2026 /PRNewswire/ -- Sceye, a U.S. aerospace and material science company building High Altitude Platform Systems (HAPS) for stratospheric infrastructure, today announced the world-first stratospheric laser tracking demonstration. The demonstration was part of Sceye's historic month-long ST1 flight and was conducted by SoftBank Corp. (TOKYO:9434, "SoftBank") in collaboration with Hitotsubashi University and the National Institute of Polar Research (NIPR), with Sceye supporting the demonstration through the use of its HAPS platform. It aimed to examine how optical wireless communication equipment should be installed on a Sceye HAPS, as well as to collect data toward realizing future optical wireless communications between satellites, HAPS and the ground. NIPR designed a corner cube reflector (CCR) for installation on a HAPS, and SoftBank developed a reflector assembly incorporating the CCR. Sceye installed and carried the CCR on the first-ever HAPS flight over Japan. For the ground-based equipment, the team built a compact, portable laser ranging system capable of tracking a HAPS, based on "Omni-SLR," a compact satellite...
