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.[2][3][4] 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.[3] The satellite design is based on the PROBA small satellite bus.[2] The payload, developed by OIP Sensor Systems, is an innovative UV, visible and NIR instrument.[5]

The mission is scheduled for launch in 2023 from the Guiana Space Centre.[1]
