• TUS (Tracking Ultraviolet Set-up), the first orbital telescope of ultra-high energy cosmic rays (UHECRs), has demonstrated that instruments of this kind have much broader capabilities and can also detect various transient luminous events, meteors, anthropogenic glow and other processes taking place in Earth atmosphere in the UV frequency range. In this short paper, we address the question whether an orbital detector of UHECRs can also register gamma-ray bursts (GRBs) via the fluorescent glow of irradiated nocturnal atmosphere. We analyse the latest Fermi GBM catalog of GRBs and properties of several active and perspective instruments. The study reveals that even an avanced detector with parameters of an optical system similar to that of the KLYPVE-EUSO (K-EUSO) or POEMMA telescopes and an appropriate trigger tuned to register events that evolve much slower than an extensive air shower, has very modest capabilities in this respect and will be able to observe only a few GRBs per year of operation.
