How does RTK GPS work?

1.What is RTK GPS?



RTK GPS stands for Real-Time Kinematic Global Positioning System. It is a satellite-based navigation system that provides highly accurate positioning information in real-time. Unlike conventional GPS systems, which typically offer accuracy within several meters, RTK GPS can achieve centimeter-level accuracy, making it invaluable for applications that require precise positioning data.



2.How does RTK GPS work?



At the core of RTK GPS technology is a process called kinematic positioning. RTK GPS systems consist of two main components: a base station and a rover receiver. The base station, typically placed at a known location with a precisely determined position, receives signals from GPS satellites and calculates corrections for errors in the positioning data. These corrections are then transmitted to the rover receiver, which is mounted on a moving object or device. The rover receiver uses the corrections received from the base station to refine its own GPS measurements in real-time, resulting in highly accurate positioning information.



The applications and benefits of RTK GPS are expected to expand further, paving the way for new possibilities in precision positioning and beyond.



For example, the ER-GNSS-M02 positioning module provides robust support for multi-frequency positioning across all major satellite constellations, including Beidou, GPS, GLONASS, Galileo, QZSS, and NavIC. With its high-precision RTK algorithm engine, achieving centimeter-level positioning accuracy becomes effortless.



Additionally, the module comes equipped with an integrated Inertial Measurement Unit (IMU) and employs a tight combination algorithm, ensuring seamless and continuous navigation and positioning output. Its compact size, minimal power consumption, and ease of system integration make it an ideal choice for various applications. Furthermore, the module supports long baseline RTK solutions and boasts fast initialization times, enhancing its versatility and usability.
