MUMBAI, India, July 25 -- Intellectual Property India has published a patent application (202421003568 A) filed by Hindustan Aeronautics Limited, Nashik, Maharashtra, on Jan. 18, 2024, for 'radio frequency aircraft interface system for reception and uniform distribution of multi frequency gnss signals.'
Inventor(s) include Jitu Sanwale; Dhan Jeet Singh; Dhanaji B Kandekar; and Devendra G Avhad.
The application for the patent was published on July 25, under issue no. 30/2025.
According to the abstract released by the Intellectual Property India: "Various navigation satellite systems (GPS, GLONASS etc.) have been used extensively for providing navigation, positioning and time information across the world for air vehicles, ships, missiles and Geographic Information System (GIS). After operationalization of Indian regional satellite constellation known as IRNSS, majority of aircraft flying over the Indian airspace may utilize IRNSS for better availability and accuracy. To acquire multi-constellations i.e. GPS, GLONASS, and IRNSS Radio Frequency (RF) band signals, the Airworthy standard Antenna(1) and Splitters(2),(3) are developed, which acquire and feed the RF signals to the Global Navigation Satellite System (GNSS) receivers onboard the air vehicles. The GNSS Antenna is capable of receiving GPS, GLONASS and IRNSS band RF signals. The signal received through GNSS Antenna is fed to active RF power splitter and further passive RF power splitters for uniform distribution to various GNSS receivers (refer figure 1). These compositional items are qualified for Airborne applications."
