Modern Multimessenger Astronomy opens unique possibility for performing
cosmological tests of the Standard Cosmological Model in the wide redshift
interval up to $z sim 10$. This is principally important for recent discussion
related to discrepancies between local and global measurements of cosmological
parameters. We present a review of multimessenger Gamma-Ray Bursts observations
currently performed and planed for THESEUS-BTA cooperative program. Such
observations allow testing the fundamental basis of cosmological models:
gravitation theory; cosmological principle of homogeneity and isotropy of the
large scale matter distribution; and space expansion paradigm. Important role
of different selection effects, which lead to systematic distortions of the
true cosmological relations, is discussed.
