Tech Chat | How to Tackle CORS Coverage Gaps via SingularXYZ Caster?

In the realm of RTK surveying, compared with radio transmission, to transmit correction data via network is more popular for its convenience and wide working range. But for regions without CORS coverage or the CORS account is very high price, users will face such trouble. So this week we’ve released a new surveying solution to tackle CORS coverage gaps via SingularXYZ Caster, realizing RTK surveying more cost-effective.

Here, we present a step-by-step guide of how to setup the X1-series as base station and deliver differential data to the Sfaira ONE series via SingularXYZ Caster over 4G, enabling you to undertake RTK measurements with ease and affordability.

Step 1: Setting Up the X1 Base Station

Insert a SIM card into X1 and power it on. Connect to X1 WiFi (SSID: X1-SN) and log in to the web interface and Access the web interface using the following credentials:

• Web IP: 192.168.10.12

You can also select the differential data format and message content. Then click OK to start up.

After the upload is completed, the Ntrip Server transmission will turn green, indicating a successful upload, and your X1 base station will be online in SingularXYZ Caster.
