Spatiotemporal Proof Platform Using the Quasi-Zenith Satellite “Michibiki”

「Spacid Co., Ltd. was established on 1 April 2026 to pursue the deployment of a positioning authentication service based on proof of location, time and actions, using the signal authentication service provided by the Quasi-Zenith Satellite System satellite “Michibiki.” As digital services based on positioning information, such as autonomous driving and drone delivery, become indispensable to society, the risks of spoofing and tampering have become apparent, making the authenticity and reliability of positioning information a new social issue. In addition to authentication signals from satellites, the company will combine observation data from multiple locations with assessments of consistency against time standards to provide a new value proposition, a “spatiotemporal authentication platform” that proves location, time and events as an integrated whole, thereby contributing to the development of a safe and secure digital society.」
