Regional Navigation Satellite System (RNSS)

A Regional Navigation Satellite System (RNSS) is a type of satellite system designed to provide positioning, navigation, and timing services over a specific geographic area rather than globally. Unlike global systems like GPS, RNSS focuses on delivering accurate location information within limited regions, which can enhance precision for applications like aviation, maritime, and personal navigation. These systems use several satellites that broadcast signals to receivers on the ground, enabling users to determine their exact location and improve navigation capabilities tailored to local needs. Examples include India’s IRNSS and Japan's QZSS.
