Sceye’s 'Silberpfeil' HAPS to Test 5G Over Japan
Sceye, a New Mexico–based company, is preparing a roughly 60-meter, helium-filled High-Altitude Platform Station (HAPS) nicknamed “Silberpfeil” to fly from the southwestern United States across the Pacific and station about 18 kilometers above the sea near Japan. Equipped with a custom antenna, solar panels and rotors, the platform will run an August test to supplement SoftBank’s 5G network by transmitting data directly to devices. Sceye has demonstrated station-keeping and multi-day endurance in prior tests — including a 2024 trial and a spring 12-day flight with more than 88 hours fixed at various positions. Other firms, including Airbus’s Aalto unit, are developing similar HAPS for remote internet, disaster connectivity and Earth observation.
A successful HAPS field trial with a major carrier (SoftBank) demonstrates alternative high-altitude connectivity that could extend coverage and affect how networks deliver service to remote or disaster-affected areas; moderately relevant to infrastructure planning but not an immediate AdTech industry shift.

Sceye and SoftBank Demo World-First HAPS Laser Ranging
Sceye, a US aerospace company developing High Altitude Platform Systems (HAPS), announced the world's first demonstration of laser ranging by tracking a HAPS from the ground. The demonstration was conducted by SoftBank Corp. during Sceye's record 30-day ST1 flight, which launched from New Mexico on August 9, 2026, and flew nearly 30,000 km to Japan and back. The ground team, using a compact, portable laser ranging system developed by Hitotsubashi University and a corner cube reflector on the HAPS developed by SoftBank and the National Institute of Polar Research, successfully tracked the stratospheric platform in real-time and received continuous reflected laser signals. This achievement is a critical step toward future optical wireless communication (free-space optics) connecting ground, stratosphere, and space for high-speed, high-capacity non-terrestrial networks.
Isar Aerospace's Spectrum Reaches Orbit, Deploys Satellites
On September 5, 2026, German startup Isar Aerospace successfully launched its Spectrum rocket from Andøya Space in Norway, achieving the first orbital flight by a private European company. The mission carried six payloads, including five satellites and a technology experiment, and marked a significant step for European launch autonomy. Measuring 28 meters tall and capable of lifting up to 1,000 kg to low Earth orbit, Spectrum is central to Isar's plans for flexible launch services. The company is scaling production with a new factory targeting 40 rockets annually, and plans future launches from Canada and French Guiana. This success meets the first milestone of ESA's European Launcher Challenge and reduces Europe's reliance on SpaceX. Isar Aerospace has raised over €500 million, including a €270 million Series D in June 2026, and secured a €200 million ESA contract.
Amazon files for 5,105-satellite mobile network
Amazon filed an application with the U.S. Federal Communications Commission to operate a 5,105-satellite network to provide service to mobile phones, with launches planned to begin in 2028. The filing follows Amazon’s acquisition of Globalstar’s satellite operations and signals plans to use Globalstar spectrum and integrate those assets with Amazon’s LEO broadband network. The move increases competition with SpaceX, which is investing heavily in spectrum and mobile constellation plans. The article notes questions about commercial demand for satellite-to-mobile services, Amazon’s reliance on delayed Blue Origin rockets for launches, and Amazon’s large cash reserves to continue investing in its satellite strategy.
