The AURORA system wants to pursue the following goals:
· Study polar lights phenomena
· Compare data obtained by AURORA with satellite data and known literature (US Standard Model 1976, IGRF Model)
The goal is to obtain, during the flight :
· Temperature measurements
· Magnetic Field Intensity measurements
· Earth surface pictures (eventually clouds)
· Telescope testing
A system diagram of AURORA is presented below to present the architecture of the experiment.
During the flight, data are stored on a hot redundant solid state memory, and the whole system is driven by a PC104 embedded computer.
. Temperature data are taken using three different kinds of sensors for comparison;
· Magnetometer data are sampled at high rate (about 100Hz) in order to sense the high frequency variation of the earth magnetic field;
· An independent GPS module is mounted on the system in order to achieve a better accuracy during post flight data process, in which spatial data will be interpolated with data collected by the sensors. GPS data from EBASS can be used for validation, once a synchronization on initial time will be performed.
· A commercial off the shelf (COTS) telescope and camera are used to take pictures looking downward from the gondola. Two pictures per minute will be taken to test the optics and system performance in the vacuum and low temperature environment.
