Positional Magnetic Local Time of the Spacecraft. mlt The eccentric magnetic local time at the fofl location is calculated following the procedures set down by Cole, (1963) and Fraser-Smith, (1987). The calculation is updated once a year using the current IGRF model field. The eccentric magnetic local time is returned as an angle from 0º to 360º, with 0º being magnetic midnight, and the angle incremented by 15º per hour magnetic local time. The local time is calculated at the sub-satellite location by assuming the local time is the Universal Time incremented by one hour for every 15º east of the Greenwich meridian. The equation of time is not used in the calculation, so this variable is only approximately the true local solar time at the sub-satellite point. The local time is also returned as an angle from 0º to 360º with 0º being midnight. degrees 0 360 Positional MEPED-0 pitch angle at the satellite. pas0 Medium Energy Proton/Electron Detector-0 degree electron detector on the NOAA 3 axis stabilized spacecraft is set to view outward along the Earth-center to satellite line.
