The GEO6 project aims at fostering possible novel applications within the scientific UC of GNSS signals, and particularly of GalileoHP G72-102SA Battery.
Ultraviolet Spectrometer / Extreme Ultraviolet Spectrometer (UVS/EUV)
The Cassegrain telescope of the UVS had a 250 mm aperture and collected light from the observation target. HP G62-110ED BatteryBoth the UVS and EUV instruments used a ruled grating to disperse this light for spectral analysis. This light then passed through an exit slit into photomultiplier tubes that produced pulses or “sprays” of electrons. These electron pulses were counted, and these count numbers constituted the data that were sent to EarthHP G62-110EE Battery. The UVS was mounted on Galileo’s scan platform and could be pointed to an object in inertial space. The EUV was mounted on the spun section of the spacecraft. As Galileo span, the EUV observed a narrow ribbon of space perpendicular to the spin axis. The two instruments combined weighed about 9.7 kilograms and used 5.9 watts of powerHP G62-110EO Battery.
The PPR had seven radiometry bands. One of these used no filters and observed all incoming radiation, both solar and thermal. Another band allowed only solar radiation throughHP G62-110EY Battery. The difference between the solar-plus-thermal and the solar-only channels gave the total thermal radiation emitted. The PPR also measured in five broadband channels that spanned the spectral range from 17 to 110 micrometres. The radiometer provided data on the temperatures of the Jovian satellites and Jupiter’s atmosphereHP G62-110SA Battery. The design of the instrument was based on that of an instrument flown on the Pioneer Venus spacecraft. A 100 mm aperture reflecting telescope collected light and directed it to a series of filters, and, from there, measurements were performed by the detectors of the PPR. The PPR weighed 5.0 kilograms and consumed about 5 watts of power. HP G62-110SO Battery
