Instrument details
Acronym TIP
Full name Tiny Ionosphere Photometer
Purpose To measure electron density in the upper atmosphere.
Short description UV photometer operating at the 135.6 nm wavelength. This emission (airglow) is produced by the recombination of O+ ions and electrons and is proportional to the square of the electron density in the ionospheric F region. Applicable at night
Background Consolidated technology
Scanning Technique Nadir only. Vertical domain: 90-750 km
Resolution 30 km
Coverage / Cycle Global in 2 weeks (comprehensive of the 6 satellites).
Mass Power Data Rate
