2.3.2 spase://NASA/NumericalData/ROCSAT-1/IPEI/PT1s ROCSAT-1 IPEI Key Parameters 2021-04-27T15:38:11Z This data set contains ion data from the ROCSAT-1 Ionospheric Plasma and Electrodynamics Instrument (IPEI). They include: composition for H+, He+, NO+, O+ ions, total density, temperature, and velocities in two different coordinate systems, namely the non-rotating Earth-centered Inertia (ECI) Coordinate System and the rotating Earth-centered Fixed (ECF) Coordinate System.
