How to log the raw data of K922 module? 

My rover has good sky view and plenty of satellites, but the fix is terrible. How can I tell if my base station is the problem?

It is very useful, thank you!👍

Hello! That is a very common observation. To put it simply: Visible Satellites (Satellites in View): These are all the satellites that are physically above the horizon and being actively track...

Thank you!

I was checking my NMEA data and noticed that the number of satellites in view is always higher than the number of satellites actually being used for positioning. What is the difference between "vis...

Have the M20X or M30X ever been used in logistics vehicles?

Which module is suggested for Marine?

Of course. We offer a free software tool for you to visualize the PRN numbers of the satellites being tracked. We can also provide you with a command to output a log file of the tracked PRN numbers.

Our GNSS modules feature the latest RTK engine and advanced anti-multipath algorithms, enabling high-precision positioning even under trees and other obstructed environments. We recently conducted...

Yes, that is a very important point! If you change the baud rate of the exact port you are currently using to communicate with the receiver, the connection will instantly mismatch. You will likely...

That makes sense. However, if I send this command while I am actively connected to COM1, will my connection drop?

Hello! You can easily configure the baud rate of any serial port using the COM command. The basic format is to specify the port name followed by your desired baud rate. For example, if you want to...

In a previous topic about high-frequency NMEA output, it was mentioned that we should use a baud rate of 115200 or higher for modules like the K803 and K902. How do I actually change the baud rate ...

Sorry for late reply Alice. You are exactly right. Basic patch antennas easily lose satellite lock when a drone banks or tilts. To answer your question: Yes, we've extensively tested the AT190 on ...

How well does your GNSS module work under tree cover? Does it still get a fix, or will it lose signal completely?

Multi-frequency helps reduce ionospheric error and improves RTK fix speed and stability.If you work in challenging environments, it’s definitely worth it.

I see many modules now support L1+L2 or even triple-frequency. Is it really necessary, or just marketing?

Both good choice, if you need even lower power consumption, you can use K901.

Thanks for replying. I am choosing now between K901 & K902...
