Development of an External Secondary Payload Unit for Time Resolved Atomic Oxygen Measurement

Autor(en): K. Zajac, A. Riemer, T. Schmiel, T. Henschel, A. Hilgers
Zusammenfassung: This paper describes the development of the external secondary payload unit APOLLON (Atmospheric Portray of Oxygen Level with Low Orbit Network) for multi-point time resolved measurement of atomic and/or molecular oxygen as a key parameter of the lower thermosphere. The measurement is based on solid oxide electrolyte micro-sensors which operate at an elevated temperature of 600-700°C, heated by an electrical resistance. Oxygen is "pumped" from one electrode to the other by an applied direct voltage and in accordance with Faradays" law. The measured current is proportional to the mass flux by electrolysis. APOLLON consist of sensor itself, the necessary electronic I/F circuitry, harness and the mechanical platform/housing and will be placed on a satellite platform in free flow. Details of the technology and design of the external secondary payload unit as well as market analysis will be presented.
