ALTIUS (Atmospheric Limb Tracker for Investigation of the Upcoming Stratosphere) is a satellite mission proposed by the Belgian Institute for Space Aeronomy and currently under development by the European Space Agency.[3][4][5] Its main objective is to monitor the distribution and evolution of stratospheric ozone in the Earth's atmosphere. The industrial consortium is led by QinetiQ Space, acting as mission prime.[6][4] The satellite design is based on the PROBA small satellite bus.[3] The payload, developed by OIP Sensor Systems, is an innovative UV, visible and NIR instrument.[7]
The mission is scheduled for launch in 2025 from the Guiana Space Centre.[2]
