When studying the outer electron radiation belt it is desirable to have both high time resolution and global coverage. In-situ satellites, such as those in geosynchronous orbit, constantly monitor the small region in which they exist, but do not give global coverage. However, medium and low Earth orbiting satellites, which slice through sections of the radiation belts at high latitudes, can be used to gain relatively global coverage with fairly reasonable time resolution. Unfortunately, in order to do this, assumptions must be made about the magnetic field and the equatorial particle distribution. To try to understand how accurately equatorial fluxes can be estimated from the data collected by these satellites, we compare data from the Navstar 10 (NS10) Global Positioning Satellite and the Combined Release and Radiation Effects Satellite (CRRES). We map data from the CRRES Medium Electrons A (MEA) sensor and High Energy Electron Fluxmeter (HEEF) to the latitude of NS10 and create average differential fluxes which can be compared to those estimated from the Burst Detector Dosimeter I (BBDI). In this poster we present the results of this study.
