How to start with SBAS mode?
2023.03.06
GNSS accuracy can reach around five meters while using SBAS, users can achieve an accuracy of two meters or better. Some receivers or OEM boards can apply SBAS corrections with additional techniques to achieve sub-meter or better accuracy. Here's a step-by-step guide for you to start with SBAS mode.
How does GNSS technology contribute to autonomous driving?
2023.01.06
Currently autonomous driving system with GNSS Module (GNSS+INS supported) enables to provide higher reliability, higher integrity positioning information. The positioning data can output under most of the challenging conditions. This blog is going to explore how does GNSS technology perform in autonomous driving.
How to evaluate the quality of GNSS data?
2022.12.09
A GNSS module is a device that provides geolocation data by receiving signals from multiple satellites of GNSS constellation. The performance of signal acquisition and tracking directly determines PVT accuracy, so it is of great significance to evaluate the quality of GNSS data.

What is IMU and how does it work in land surveying?
2022.09.02
Using IMU RTK receiver will definitely improve surveying efficiency: with no on-site calibrations and no need to center the bubble, much more time is saved, more points are safely accessed and results are accurate, reducing repeated work.
How to mitigate the impact of ionosphere on GNSS positioning?
2022.08.22
One of the largest errors in the GNSS measurement is attributable to ionospheric delay. How do surveyors metigate the ionospheric effect?
