While ‘in-situ’ measurements are the most important feature of space plasma observations, multi-point observations are essentially necessary to understand the significance of such observations in the context of macroscopic phenomena. A possible constellation of CubeSats has been examined for a future geospace mission to realize multi-point or super multi-point observations in geospace. As a first step, we are developing a compact high-energy electron analyzer, nicknamed PINO (Particle Instrument for NanO-satellite) supported by the JSPS KAKENHI and the collaboration with the Kyushu Institute of Technology. PINO will be installed on a 2-U CubeSat, BIRDS-5J, and, now, the FM (Flight Model) of BIRDS-5 fleets (two 1U CubeSats and one 2U CubeSat) are going, and all the satellites will be ready for launch this spring. They will be released from the international space station (ISS) in 2022. PINO will observe precipitating high-energy electron fluxes in the northern hemisphere. Due to the electrical power budget limit, we will turn on PINO only for continuous 5 minutes in an orbital revolution. Thus, we will focus the PINO observation on conducting simultaneous observations of precipitating high-energy electrons from the outer radiation belt at low and high altitudes. In this presentation, we will present the results of the PINO development and current plans for scientific observations.
