High-precision positioning is not only applied to the surveying and mapping industry centimeter-level high-precision positioning CORS, as well as sub-meter RTK and sub-meter RTD, etc., so you know what is the difference between them? Mainly used in which areas have? After reading this article you will know.

1, centimeter-level RTK (multi-frequency carrier phase difference)

Statistical accuracy: horizontal ≤ 5 centimeters, vertical ≤ 8 centimeters

The platform broadcasts multi-frequency RTK (Real-Time Kinematic, real-time dynamic carrier phase difference) data, and dynamic centimeter-level positioning can be realized in the open environment.

Application areas: applied to automatic driving, surveying and mapping, UAV positioning, precise operation services and other scenarios.

In the field of surveying and mapping measurement, it is often connected with RTK measurement instruments, UAVs, etc. in the form of CORS account to reach the fixed solution to carry out measurement operations.

2、Sub-meter RTK (single-frequency carrier phase difference)

Statistical accuracy: horizontal ≤ 80 cm, vertical ≤ 1.2 meters

The platform broadcasts single-frequency RTK data, which can realize sub-meter level positioning in open environment.

Application areas: applied to V2X, lane-level navigation, motorcycle management, road management, park management, logistics management and other scenarios.

3、Sub-meter level RTD (pseudo-differential)

Statistical accuracy: horizontal ≤ 1.5 meters, vertical ≤ 3 meters

The platform broadcasts RTD (Real-Time Differential, real-time dynamic pseudo-distance differential) data, which can realize sub-meter positioning in open environment.

Application areas: applied to cell phones, smart wearable positioning and other scenes.
