摘要

The fourth stage (PS4) of the Polar Satellite Launch Vehicle (PS4-PSLV) of the C-38 mission, was used for the first time as an orbiting platform to carry out measurements of atmospheric parameters, on June 23, 2017. The measurements were made in two phases. i) During the initial launch phase wherein the launch vehicle traversed from the launch pad to an altitude of 500 km. ii) During the 10 orbits at an altitude of 350 km (after the PS4 stage was brought down in a controlled manner). The Ionization Density and Electric-field Analyzer (IDEA) payload onboard the PS4 stage provided electron density (Ne) and electric field (EF) information in the F region altitudes. The present paper highlights the results from the Langmuir probe component (Ne) during the initial launch phase. The presence of a top side enhancement, is revealed in the initial phase IDEA measurements and simulations using IRI and TIE-GCM models confirm the possibility. The first of their kind in-situ observations of top side electron density enhancement concurrent with the operation of the PS4 stage of PSLV demonstrates the plausible role of rocket burn and exhaust gases in modulating the ionosphere in the vicinity. The results indicate that the unique trajectory of the PS4 orbiting station (in the initial phase) serves as an ideal one to investigate top side electron density enhancements. Further, the mission underlines the fact that the novel orbiting platform, will be useful for carrying out measurements of multiple parameters in the near-Earth space.
