How GNSS Receiver Works
Understanding how GNSS receivers work is crucial for anyone leveraging global navigation systems. These compact but powerful devices play a pivotal role in deciphering signals from an array of satellites orbiting the Earth, enabling precise location tracking across various applications.
At its core, a GNSS receiver intercepts radio signals broadcasted by satellites which are part of the Global Navigation Satellite System. Each satellite transmits information about its position and the current time at regular intervals. Once a receiver catches signals from at least four satellites, it begins the process of trilateration to calculate the user's exact location. This involves determining the distance between the receiver and each satellite, factoring in the time it takes for each signal to reach the receiver.
The magic lies in the receiver's ability to convert time delay into distance, considering the speed of light as a constant. Accuracy is paramount, and it's here that advancements such as Real Time Kinematic (RTK) positioning and multi-frequency receivers make a significant impact. RTK enhances precision by correcting signal distortions, while multi-frequency receivers mitigate errors caused by the Earth's atmosphere.
