Stage 1 popup.stage_title Head Medvedskyy Mykhailo M., Кандидат фізико-математичних наук Registration Date 23-02-2021 Organization Main Astronomical Observatory popup.description2 There are proposed and developed the realization of the GNSS-technology of autonomous PPP-navigation of highly-dynamic flying vehicles (HDFV) using onboard GNSS-observations, accurate ephemeris-timing corrections for navigation of the decimeter level of accuracy in real time on board HDFV and/or for trajectory measurements on the poligons. The algorithms of PPP-solutions with the use of the code and carrier-phase GNSS-observations, which have been pre-processed, and with the use of accurate ephemeris-timing corrections of GNSS satellites are developed. Algorithms for calculating ephemeris-timing corrections for GPS satellites based on SBAS EGNOS messages have been developed and tested. An estimate of the accuracy of the SBAS EGNOS orbital, time, and ionospheric corrections was performed, which showed that either IGS forecast data (ultra-rapid) or GNSS satellite onboard BRDC-data could be used to implement PPP-navigation. The prototype of software (PS) (in the MatLab programming system) for processing on-board GPS-observations and autonomous PPP-navigation is created. Experimental verification of PS of the PPP-navigation in the mode of post-session processing was carried out, which in general showed the achievement of centimeter/decimeter (RMS) level of accuracy. The basic requirements to the software-mathematical complex for PPP-navigation in real time with use of onboard multisystem GNSS-observations are defined.  Product Description popup.authors Emets' Adel' I.
