Space Environment Monitor for NPOESS (SEM-N) Sensor Suite
Abstract
The Space Environment Monitor for NPOESS (SEM-N) is a compliment of three space particle sensors to be flown on the National Polar-orbiting Operational Environmental Satellite System (NPOESS) which will take measurements to produce space environment data products for the near earth environment. SEM-N will fly on the first NPOESS spacecraft to be launched in 2013. Five Environmental Data Records will be retrieved by the SEM-N instrument package: auroral boundary, auroral energy deposition, energetic ions, medium energy charged particles, supra-thermal through aurora particles. Multiple angle, continuous energy spectral coverage will be provided for electrons from 30 eV to 1 MeV and for protons from 30 eV to >1000 MeV. The SEM-N coverage extends that of the current SEM-2 instrument and fills gaps in the present energy spectrum. The heritage-based SEM-N complement consists of the DMSP Special Sensor J5 (SSJ-5) for low energy measurements, the APL Energetic Particle Sensor (EPS) for medium energies, and an omnidirectional High Energy Sensor (HES) for high energy protons. This paper will present details on the SEM-N sensors and their expected performance.
