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.

In our previous blogs, we introduced a free method using Amazon Cloud & SNIP for beginners who want to build their own CORS platform. However, some of our SV100 users recently said that the 750hrs free trial period of Amazon Cloud is a bit short. So in today's blog, we will share a new method of free trial throughout the year – how to build your CORS server with Alibaba Cloud?

In order to obtain higher accuracy of GNSS, we usually use DGPS (Differential Global Positioning System) to help improve accuracy. Both using the differential data to correct GNSS positioning, what’s the main difference between RTK (Real Time Kinematic) and RTD (Real Time Differential)? And what are the differences in their application fields? Let's discuss it in today's blog.

Different users have their own work habits and preferred software. In order to facilitate our vast user groups, our RTK products are compatible with common field surveying software and GIS software on the market. Today we will take Mobile Topographer as an example to see how we can make our Y1 GNSS receiver work with it.

To obtain higher efficiency, nowadays more and more large-scale projects combine total station and GNSS receivers to complete complex survey tasks. But in this case, the most troublesome thing is the subsequent processing of point data in different coordinate systems. If data problems are found after processing, users may even need to do some re-measurement.

In the previous chapters, we talked about how to site an ideal location for a CORS station and analyze GNSS data quality. After these preparations, we can start building the CORS station.
