HiLetgo VK172 G-Mouse USB GPS/GLONASS USB GPS Receiver for Windows review
Quick take
The HiLetgo VK172 G-Mouse is a compact USB GPS/GLONASS receiver that streams GPS data (NMEA) to Windows over a COM/serial connection for GPS-aware software and projects. It can be a good value for makers, radio operators, and anyone who needs a simple location data source, but buyer expectations should be set: it is primarily a data receiver, configuration is on you, and GPS and GLONASS are not available at the same time.
Pros and cons
Pros
- Outputs standard NMEA data for many GPS-aware apps (commonly accessed via a serial COM port).
- Supports WAAS/EGNOS/MSAS (DGPS) and uses WGS-84 as its reference coordinate system.
- Reported to work with Windows, and some buyers also use it in non-Windows setups with compatible serial drivers.
- Reasonable sensitivity for a dongle, with a listed tracking sensitivity of -162 dBm.
Cons
- GPS and GLONASS cannot be used simultaneously, you must choose one mode.
- Driver and configuration experience can vary, and there is no included documentation or software for setup.
- Performance can degrade in challenging conditions (for example, one report claims it stops working correctly in extreme cold).
What buyers think
Buyer-review evidence is most consistent around setup and data behavior. Many buyers describe getting NMEA data streaming immediately after the USB-to-serial COM port is recognized, then using terminal tools or GPS apps to read location updates. The receiver is also viewed as useful as a “data source” rather than a self-contained navigation device, which matches the expectation that it only provides GPS information while other software handles mapping, logging, or reporting. Review evidence is limited regarding long-term reliability and detailed RF performance in controlled conditions, but the overall theme is that it works well for technical use cases where you are comfortable with COM ports and app integration.
What the HiLetgo VK172 G-Mouse actually is
This is a USB GPS/GLONASS receiver designed to feed location data into other systems. It is not a complete navigation unit or an app you install. Instead, it relies on your computer (or compatible environment) to read the incoming stream of GPS sentences and turn them into coordinates for whichever program you are running.
Key positioning specs include a WGS-84 reference coordinate system, listed tracking channels (56), and a listed tracking sensitivity of -162 dBm. It also supports DGPS via WAAS/EGNOS/MSAS.
Setup and compatibility: what tends to be smooth, what needs attention
How it connects
On Windows, buyers commonly access the receiver through a standard COM port after the device is recognized. That makes it a natural fit for software that can ingest GPS over serial, plus DIY projects that read NMEA output.
Drivers and configuration
Driver behavior appears to vary depending on your existing environment. Some buyers report that it enumerates without needing extra downloads, while others note that technical steps may be required. There is also emphasis that configuration is on the user, and configuration utilities may be separate from the receiver itself.
GPS vs GLONASS mode
A clear limitation that comes up is mode selection. GPS and GLONASS are not used simultaneously. If your project relies on both constellations at once, this receiver may not match that requirement.
Performance and real-world use notes from buyers
Review themes lean toward practical results: buyers use the VK172 to add positioning to systems like PCs, Raspberry Pi projects, and GPS-aware apps for tasks such as location reporting. Many describe it performing well once configured and left running, while initial setup may require patience if your software expects a particular serial format or baud rate.
There is also a buyer report claiming it can stop working correctly after exposure to extreme cold. That suggests you should avoid expecting consistent performance across harsh weather without additional testing for your specific conditions.
Pros and cons, summarized for buying decisions
When it is a good fit
- You want a budget USB GPS receiver that feeds NMEA to Windows software (or other systems that can read a COM/serial GPS stream).
- You are comfortable with basic technical setup, like choosing the correct serial port in your application.
- You need DGPS support (WAAS/EGNOS/MSAS) and WGS-84 coordinates for standard GPS workflows.
When you should skip it (or look for a different approach)
- You require simultaneous GPS and GLONASS. This receiver is designed around selecting one mode at a time.
- You need a turnkey navigation product with included software and instructions, the VK172 is primarily a sensor that outputs data.
- You plan to rely on it in extreme cold without verifying performance for your environment.
Verdict: is the HiLetgo VK172 worth it?
If your goal is to add GPS location data to an app, PC, or project, the HiLetgo VK172 can be a practical low-cost USB receiver. It is best for buyers who are comfortable reading NMEA over a COM port and who do not need simultaneous GPS plus GLONASS. If you need a guided, plug-and-play navigation experience, or you specifically need both constellations at the same time, you will likely be happier choosing a different class of device.
Price and availability
Check current availability and pricing before you buy, since this type of USB GPS accessory can vary by listing and season.
FAQ
Does the HiLetgo VK172 output standard NMEA sentences?
Yes. It is commonly used as a GPS data source that streams NMEA-style output that GPS-aware apps can read over a serial (COM) connection.
Can I use GPS and GLONASS at the same time with this receiver?
No. It supports GPS or GLONASS mode selection, but not simultaneous operation.
Do I need to install drivers on Windows?
Some setups recognize the device without extra steps, while other environments may need driver help. Plan for the possibility that you may need to install or adjust driver/COM port settings.
Is this a navigation device with a screen and maps?
No. It is a displayless USB receiver meant to provide GPS data to other software that handles mapping, logging, or reporting.
Will it work indoors?
Buyer feedback suggests it can work even when not outdoors, but GPS reception generally improves with better satellite visibility. If you get weak results, try a more open location.
What operating systems is it intended for?
It is listed for Windows 10/8/7/Vista/XP/CE. Some buyers also report success on other platforms when compatible serial drivers and tooling are available.
