ALTIUS (Atmospheric Limb Tracker for Investigation of the Upcoming Stratosphere) is a satellite mission proposed by theBelgian Institute for Space Aeronomy and currently under development by theEuropean Space Agency (ESA). Its main objective is to monitor the distribution and evolution ofstratospheric ozone in the Earth's atmosphere.[2][3][4]
The industrial consortium is led byQinetiQ Space (nowRedwire Space[5]), acting as mission prime.[6][3] The satellite design is based on thePROBA small satellite bus.[2] The payload, developed byOIP Sensor Systems, is an innovativeUV,visible, andNIR instrument.[7]
The mission is scheduled for launch in 2027 from theGuiana Space Centre onVega-C.[8][9][10]
ALTIUS: Develop and operate a small mission dedicated to the operational monitoring of stratospheric ozone profiles.
