The Experimental Results from SURA HF Facility and CSES Satellite

Abstract

Since June 2018, SURA heating facility in Russia has carried out the experiments in emitting high frequency (HF) radio waves with O-mode and disturbing the ionosphere, together with the in-orbit satellite of China Seismo-Electromagnetic Satellite (CSES). By collecting the observing data onboard CSES including electric field, in-situ plasma parameters and energetic particle flux, the results show that in local daytime no pumping waves were detected by the electric field detector (EFD) on CSES even the emitted power reaching 90 MW, and no any obvious plasma disturbances were observed from CSES. While in local nighttime, the pumping waves were clearly distinguished in HF-band electric field at the emitted frequency with the emitted power only 30MW, in which the power spectrum density of electric field was larger than the normal background to an order of magnitude, with the propagating radius exceeding 200 km. This joint experiment of SURA-CSES illustrates that, CSES can cross SURA facility within a quite near distance with present designed orbit, which can insure the effective heating time from SURA and make CSES most possibly to observe the perturbations at the topside ionosphere excited by SURA.
