Abstract

The Compact Environmental Anomaly Sensor (CEASE) is an instrument designed to provide real-time space environment hazard warnings to the host spacecraft. In this paper, we report on the first year of on-orbit operation of this instrument and describe its performance with particular emphasis on its engineering, hazard-warning function. Index Terms--Dosimetry, proton radiation effects, radiation detectors, satellites.

Abstract

The solar cycle dependence of dose rates in the low-altitude 'horns' of the outer zone electron belt is examined using data from TSX5/CEASE (solar maximum epoch) and APEX/PASP+ (solar minimum epoch). It is found, after normalizing the dose rates to account for the different shielding geometries, that the ratio of PASP to CEASE dose rates is ~4 for L > 4. This is contrary to the equal dose rates predicted by the NASA AE8MIN and AE8MAX models. Index Terms--Electron dose, low earth orbit, radiation belt, solar cycle variation.
