Global Positioning Systems
Global Navigation Satellite Systems (GNSS) offer essential functions that involve positioning and timing needed for various devices' daily operations, just like the Internet of Things links a strong information stream between individuals and globe powering processes. GNSS utilizes satellite technology to offer insight into the connected devices' geographic location. GNSS is a broad term that describes different global systems such as the Global Navigation Satellite System (GLONASS), GPS, Galileo, and BeiDou. This paper discusses GLONASS, GPS, Galileo, and BeiDou global systems showing their differences and the international cooperation future with GNSS.
GPS
GPS is the most senior GNSS system, thus being considered the GNSS world pioneer. It began functioning in 1978; however, it was officially made available to be used worldwide in 1994. It was discovered due to the need to acquire a military navigating system that was independent. As it was being established, increased complexity was incorporated into the GPS to ensure it was highly accurate and secure against spoofing and jamming attempts. GPS functions in an L-Band frequency, a radio spectrum's portion is ranging between 1 GHz and 2. Currently, GPS, compared to other systems worldwide it the most accurate.
Global systems such as GPS get assistance from regional augmentation networks like the Wide-Area Augmentation System (WAAS). Every regional system provides unique benefits across different frequencies’ range. Using a combination of constellations is advisable because it combines the benefits of those constellations. Such systems give data required for safe aircraft navigation.
