No matter as a surveyor or other ordinary people, everyday we are using GNSS (Global Navigation Satellite System) in our daily work or life, such as GPS and BDS. Have you ever wondered how GNSS works?

As a surveyor, you've probably heard the word NMEA or GPGGA many times. Such as when using a GNSS device with an echo sounder, it always requires NMEA-0183 data stream from GNSS device to the echo sounder.

As surveyors all know, the first step when we use RTK receivers is to connect it to a data collectors via Bluetooth. But sometimes it can be difficult for you to search or connect to Bluetooth, so sometimes it still annoys people even if it's just a simple step.

For many in the GIS industry, QGIS is a very familiar desktop tool for editing and analyzing geospatial data. When field tasks are required, Qfield, the mobile phone software of the same series, is also often used for collecting GNSS data.

SingularXYZ has released the T8 Pro GNSS tablet months ago, as an ideal product for GIS application, we’ve received plenty of good feedback from the market. T8 pro tablet works well with different 3rd party GIS software from different users.

Usually when surveyors use RTK receivers, Ntrip protocol is used more or less for data transmission. And sometimes you don't even know you’re using it. So do you know what Ntrip is and how does it serve our precise positioning?
