SoftBank and Sceye achieve milestone in stratospheric communications through successful laser-based HAPS tracking
Executive summary: SoftBank Corp.'s ground team successfully tracked a Sceye stratospheric platform in real-time using laser signals for distance measurement. The test validates optical communication technology (FSO) which is essential for high-speed, low-latency data transfer between ground stations and stratospheric platforms.
Who is involved: SoftBank Corp. and Sceye.
Likely next: Integration of these laser-ranging capabilities into broader HAPS commercial service testing and potential deployment for direct-to-device connectivity.
SoftBank Corp. and Sceye have successfully executed a world-first demonstration involving real-time ground tracking and laser ranging of a High-Altitude Platform Station (HAPS). This technical achievement validates the feasibility of Free-Space Optical (FSO) communication links between ground, stratosphere, and space, marking a critical step toward commercializing stratospheric connectivity.
What's next — scenarios
Base: Successful commercial rollout of HAPS-FSO services (60%)
Telecom operators adopt HAPS to expand coverage in remote areas using optical links.
- Successful long-term stability tests of laser links
- Regulatory approval for stratospheric spectrum use
Downside: Technical or regulatory hurdles delay commercialization (30%)
Increased capital expenditure for SoftBank and Sceye without immediate revenue from HAPS.
- Failure to maintain continuous laser signal in adverse weather
- Stringent new international airspace or frequency regulations
Upside: Rapid integration with satellite networks (10%)
HAPS becomes a key layer in a multi-tier orbital/stratospheric connectivity architecture.
- Partnerships with LEO satellite constellations for hybrid communication
