JAXA picks ArkEdge for LEO PNT study

ArkEdge Space, a Japanese space start-up based in Tokyo, providing comprehensive solutions from planning and design to mass production and operation of small satellite constellations, has been selected by the Japan Aerospace Exploration Agency (JAXA) as the project provider for the Feasibility Study (Part 1) on the Low Earth Orbit PNT (Position, Navigation, Timing) System (LEO-PNT) to be conducted by JAXA. The project commenced on the 11th of October, 2024.

LEO-PNT is a constellation of small satellites, orbiting at an altitude of 900-1,200 km. This is lower than the conventional Global Navigation Satellite System (GNSS) orbiting at an altitude of approximately 20,000 km. The system is expected to provide high-precision PNT information worldwide.

LEO-PNT’s high-intensity positioning signals are expected to complement the weak signal strength of conventional GNSS signals reaching the Earth’s surface, which are more susceptible to various types of interference, both natural and human-made. The more accurate positioning information provided by LEO-PNT is also expected to be used in many other fields, such as autonomous driving.
