The Viettel-1 LEO communication satellite orbits in Low Earth Orbit (LEO). A high-angle, wide shot shows the Viettel communication satellite deployed against the curvature of the Earth and the black void of space. The spacecraft features two large, rectangular multi-junction solar arrays extended to the sides, reflecting intense sunlight. A prominent, high-gain gold-mesh parabolic antenna is positioned at the base, designed for Direct-to-Device (D2D) 5G-Advanced connectivity. The main bus is wrapped in silver and gold multi-layer insulation (MLI), prominently displaying the Viettel corporate logo as it provides ubiquitous network coverage to remote regions during the Mobile World Congress (MWC) in Barcelona, Spain, on March 5, 2026.
