Outline of Final Research Achievements

Precise satellite positioning, which achieves centimeter accuracy using the carrier phase, often loses accuracy due to obstacles such as buildings and the lack of the number of visible satellites depending on the place and time. It affects the availability of location-based services. This study has developed a system that predicts positioning accuracy at a specified time and location with information about obstacles such as buildings from aerial point cloud data and the satellite constellations. In addition, we have developed a system for monitoring landslides in a local region as a service that utilizes precise location information. The proposed system achieves less than one-centimeter accuracy using a proposed positioning algorithm.

Academic Significance and Societal Importance of the Research Achievements

高精度衛星測位インフラの民間利用が正に始まりつつあるところである.従来の数メートル精度からセンチメートル精度になると,精度が良好なときとそうでないときの精度の格差が大きく,センチメートル精度を想定した位置情報応用サービスは可用性が著しく低下してしまう.本研究では,時刻や場所に依存して不安定な測位精度の状況においても,その精度を予測できるようにすることでサービスの利用性を向上させ,高精度衛星測位の利活用が早期から広く行えるようにすることに寄与する.安定した高精度衛星測位情報の利用はモバイルセンシング,リモートセンシングの両方において,取得データの利用性を高めることにつながる.
