Next-Generation Earth Observation, PNT, and IoT Communication Enabled by Microsatellite Constellations

Abstract

Microsatellite constellations are becoming a practical platform for Earth observation, positioning, and communication. ArkEdge Space Inc. has developed a standardized 6U satellite bus and a streamlined production and operational framework that enable rapid, flexible mission deployment. Demonstrations include high-resolution optical remote sensing, LEO-based positioning experiments, and low-power IoT and maritime VDES communication. This paper summarizes the system architecture, service capabilities, and mission results such as ONGLAISAT and AE2a, highlighting the growing potential of microsatellites as an accessible and resilient infrastructure for photogrammetry and remote sensing.
