SoftBank and Sceye achieve world-first laser ranging via HAPS to advance free-space optical communications
Executive summary: SoftBank Corp. successfully performed the world's first laser ranging measurement by tracking Sceye's stratospheric platform from a ground station in real-time. This test proves the viability of Free-Space Optical (FSO) communication links across ground, stratosphere, and space, which is essential for next-generation high-speed data networks.
Who is involved: SoftBank Corp. and Sceye.
Likely next: Expansion of testing to broader network integration and move towards commercial deployment of HAPS-based communication services.
SoftBank Corp. and Sceye have successfully demonstrated real-time laser telemetry by tracking a High Altitude Platform Station (HAPS) from the ground. This milestone validates the technical feasibility of Free-Space Optical (FSO) communications between terrestrial, stratospheric, and space layers. The achievement marks a critical step in the commercialization of high-speed, low-latency connectivity via the stratosphere.
What's next — scenarios
Base: Successful commercial HAPS rollout (60%)
Establishment of a new layer of global connectivity infrastructure reducing reliance on traditional satellites.
- Successful integration with existing core networks
- Regulatory approval for stratospheric spectrum use
Upside: Dominance in FSO standard (25%)
SoftBank and Sceye set the global technical standard for ground-to-stratosphere optical links.
- Rapid adoption by other telecom operators
- Breakthrough in laser efficiency and range
Downside: Regulatory or technical hurdles (15%)
Slowdown in commercialization due to airspace restrictions or signal interference issues.
- New international aviation restrictions in the stratosphere
- High cost of hardware scaling
What to watch
- Integration of HAPS signals into SoftBank's core network
- Regulatory decisions regarding stratospheric spectrum allocation
- Expansion of the Service Test Program to other geographic regions
