Sceye and SoftBank Corp. achieve world-first ground-to-stratosphere laser telemetry demonstration for HAPS
Executive summary: SoftBank Corp.'s ground team successfully tracked a Sceye stratospheric platform in real-time, receiving continuous reflected laser signals to demonstrate laser telemetry. The successful demonstration proves the viability of Free-Space Optical (FSO) communications, which is essential for high-speed data transfer between ground, stratosphere, and space.
Who is involved: Sceye (platform provider) and SoftBank Corp. (telecom operator).
Likely next: Expansion of the Service Test Program to include full-scale commercial connectivity tests and integration into existing telecom backhaul networks.
Sceye and SoftBank Corp. have successfully demonstrated real-time laser telemetry by tracking a High Altitude Platform Station (HAPS) from the ground. This milestone validates the continuous reception of reflected laser signals, a critical component for advancing Free-Space Optical (FSO) communications. The test establishes a technical foundation for seamless data links between ground stations, the stratosphere, and space.
What's next — scenarios
Base: Commercial HAPS integration (60%)
HAPS become a standard component in telecom backhaul and direct-to-device services.
- Successful integration with SoftBank's core network
- Stabilization of FSO signal reliability in varying weather
Upside: Global FSO standard adoption (25%)
Rapid deployment of stratosphere-to-space communication constellations by major tech players.
- Demonstration of low-latency connectivity with satellite networks
- Significant reduction in hardware cost per unit
Downside: Regulatory or technical hurdles (15%)
Slower commercialization due to airspace management issues or signal interference.
- New restrictive airspace regulations for HAPS
- Technical failure in high-density atmospheric conditions
What to watch
- SoftBank Corp.'s integration of HAPS data into its core network architecture
- Regulatory decisions regarding stratospheric airspace management
- Scalability tests of FSO signals during extreme weather events
