The Global Navigation Satellite System (GNSS) is an unparalleled beacon, providing location-based services worldwide. However, within GNSS, not all solutions are created equal. Real-time kinematic (RTK) GNSS technology emerges as a transformative force, elevating the precision of satellite navigation systems. Emlid, a leading RTK receiver manufacturer, harnesses GNSS technology to deliver unmatched accuracy across diverse industries and applications.
Unlocking Precision: Understanding GNSS Positioning
GNSS serves as the cornerstone for users globally to ascertain their geographical coordinates through satellite signals orbiting the Earth. The conventional GNSS positioning method calculates the duration for a signal to traverse from a satellite to a receiver. By measuring the travel time of signals transmitted from at least four satellites, a GNSS receiver can determine the user’s location with an accuracy of a few meters—a level of precision suitable for many everyday applications.
However, scenarios demanding acute accuracy, where precision at the centimeter level is imperative, exceed the capabilities of standard GNSS readings. Here, RTK GNSS emerges as a game-changer, offering centimeter-level location data crucial for surveying, agriculture, and autonomous vehicles.
The Revolutionary RTK GNSS Technology
RTK GNSS represents a sophisticated technique designed to rectify the inherent errors in basic GNSS signals. As satellite signals traverse a vast 20,200-km journey through the ionosphere and atmosphere to reach GNSS receivers, various factors such as atmospheric disturbances, physical obstructions, and environmental effects can distort the signals, introducing delays and reducing accuracy.
In response to these challenges, RTK GNSS employs a two-receiver system—one stationary base station with a known location and one mobile unit, or “rover.” The rover and base station receive signals from the same constellation of satellites. Subsequently, the base station transmits error corrections based on its fixed position to the rover, enabling the rover to adjust its calculations and narrow positional data to the centimeter level.
Selecting the Optimal Receiver With Emlid
When considering a suitable RTK GNSS receiver, Emlid advises clients to evaluate its capability to handle varying frequency bands. Single-band and multi-band receivers offer high-precision results, yet their performance in diverse environmental conditions differs.
Multi-band units, such as Emlid’s Reach RS2+ receivers, leverage multiple frequency bands to facilitate rapid fix solutions—often within five seconds—and maintain reliability even in challenging environments. These multi-band receivers excel over longer baselines in locations with partial sky visibility. For those seeking to delve deeper into the distinctions between single-band and multi-band receivers, Emlid offers an informative article elucidating complex technology into accessible information.
