When using SV100 GNSS receiver as base, it can be set up as both CORS station or portable base. In previous blogs, we’ve mentioned how to configure SV100 as reference stations via PC. Today, let us introduce how to set up SV100 as a portable base in the field for your surveying rovers, tractors or construction machines.

When using RTK equipment for surveying, the most important performance of RTK should be its accuracy and re-initialization time. The former determines the work quality, while the latter determines work efficiency.

With the popularization of RTK technology in all walks of life, the global CORS coverage is getting higher and higher. Many surveyors, GISer, farmers, etc. started to use CORS instead of setting up RTK base stations themselves.

For the application of GNSS positioning and navigation technology, such as surveying, machine control, precision agriculture, etc., RTK technology is most commonly used. So what are the main sources of RTK error? How should we avoid these errors in daily use so as to obtain more accurate positioning?

In past blogs, we've introduced what IMU is and how it works on our Y1 GNSS receiver. Nowadays, more and more GNSS receivers integrate IMU module for greater convenience and higher efficiency. So to judge the performance of the IMU function become a focus. Today, we will introduce a conventional method of testing the accuracy of IMU, so that you can test your own equipment.

In daily surveying, we usually set up base stations on known points. What if there are no known points or the known points are far apart in some large-scale projects? How can we ensure the accuracy when shift or re-start the base station?
