In GNSS related applications, the GNSS antenna is the first crucial step - receiving satellite signals. The GNSS data quality decided the final positioning accuracy in a large range. Whether you're doing centimeter-level land surveying, precision agriculture, or vehicle navigation, understanding the antenna types and selecting the right one can directly impact your positioning performance. So what types of GNSS antennas are commonly used today? What are their features, advantages, and where are they best applied? Let's have a comprehensive knowledge and comparison.

In satellite positioning, the original calculated coordinates is the location of the GNSS antenna phase center (APC). To accurately determine the coordinates of the measured point, it's essential to understand the relationship between the APC and the measured point, and how to calculate this conversion. In today's blog, we'll delve into what the antenna phase center is, how it's calculated, and why it matters for your field operations.

In daily RTK measurement, we usually need to input the height of the ranging pole in order to convert the coordinates into a ground target point. Have you ever wondered the original position measured by the GNSS receiver are? Is it above, below or inside the GNSS receiver?

Since our SV100 GNSS receiver was released half a year ago, many users have shown great interest and got positive feedback about it. Most of our users have used the SV100 as a reference station for their CORS or monitoring projects.
