Stage 3 popup.stage_title Head Zhalilo O.O., Кандидат технічних наук Registration Date 18-02-2016 Organization Main Astronomical Observatory popup.description2 There are designed and experimentally elaborated the domestic processing technologies of on-board GNSS-observations of LEOS to determine the parameters of its movement by the PPP (Precise Point Positioning) method and estimating the ionospheric delay of navigation signals for modeling (at the next stage of the project) the altitude distribution of the total electron content (TEC) of the ionosphere in accordance with the objectives of space project "Ionosat-Micro". There are carried out the gathering and analysis of on-board GPS-observations of specialized foreign LEOS COSMIC and GRACE for testing the modules of the experimental software. The results of coordinate-timing determination by PPP-method using the auxiliary information from the international service IGS and the French space agency CNES are obtained. Based on the comparison of the results of processing of on-board GPS-measurements with the LEOS COSMIC reference coordinates it is proved the achievement of accuracy of current coordinates determination at the level ~ 0.04-0.09 m (RMS). According to the results of on-board dual-frequency GPS-observations there are evaluated and analyzed the ionospheric combinations containing the information on the TEC of the ionosphere for further modeling of altitude distribution of the TEC using Radio Occultation technologies.
