Sattrack is a system used to monitor satellites' positions and orbits, while GPS (Global Positioning System) is a network of satellites that provides location and time information to GPS receivers on Earth. In essence, sattrack is more specific to tracking satellites, whereas GPS is a broader system for determining precise location on Earth.
The Satrack system works by using satellites to track the position of objects or vehicles equipped with a GPS transceiver. Satellites in the Global Navigation Satellite System (GNSS) network communicate with the GPS transceiver to determine the object's location in real-time. This information is then relayed back to a central monitoring station for tracking and monitoring purposes.
No, NASA did not invent GPS. GPS technology was developed by the United States Department of Defense and became fully operational in 1995. NASA has used GPS technology in its missions for navigation and tracking purposes.
Roger Easton played a significant role in the development of GPS in the 1960s as part of the US Navy. He is credited with inventing the concept of GPS, but it was a collaborative effort with a team of engineers, scientists, and researchers. GPS technology became fully operational in the 1990s.
