What’s is NTN?NTN：Non-Terrestrial NetworksNTN has become a general term for any network involving non-ground flying objects.NTNs include Satellite Communication Networks, High Altitude Platform Systems (HAPS) and Air-to-ground networks, as shown in the figure below. 1.1 Satellite Communication NetworksSatellite Communication Networks is an airborne platform include: LEO(Low Earth Orbiting)、ME……
RNSS (full name: Radio Navigation Satellite System) is a satellite radio navigation service in which users receive satellite radio navigation signals. RNSS completes the distance measurement independently to 4 satellites at least, and calculates the user’s position, speed and navigation parameters. Systems such as GPS are typical RNSS systems. RDSS (full name: Radio Determination Satellite Se……

A low-power wide-area network (LPWAN or LPWA network) is a type of wireless telecommunication wide area network designed to allow long-range communications at a low bit rate among things (connected objects), such as sensors operated on a battery. The low power, low bit rate, and intended use distinguish this type of network from a wireless WAN that is designed to connect users or businesses, and c……
Global Navigation Satellite System (GNSS), also known as global satellite navigation system, is a space-based radio navigation that can provide users with all-weather 3-dimensional coordinates, speed and time information at any point on the earth’s surface or in near-earth space. GPS. It consists of one or more constellations of satellites and their augmentation systems needed to support a particu……
