VK172 GPS module

Firstly, I'd like to get out of the way that I'm not an expert, just using this for accurate time, location, and messing around occasionally. In my, albeit not super accurate or lab controlled testing, this module has performed very well. And for $15 you can't really complain. The first GPS lock didn't take long at all, which surprised me because most of the reviews mentioned that it would, my 1st lock took about 5 minutes. The module seems to operate even without a computer as long as it's connected to a power source. So when you see a blinking green light, you know you've got some sort of GPS lock. The quality of that lock can very greatly, but you should at least have 2 satellites locked. I decided to try it on my Windows 8.1 PC, so I downloaded the software and driver from the U-Blox website, after then installing the driver and starting the software I plugged the GPS receiver in with a USB extension cable and set it next to a window. After around 5 minutes, I saw a flashing light on the GPS receiver and a I saw a few satellites were locked on in the software. After about 10 minutes I had 7 satellites locked, and 10 that were being heard. There was some minor drift in speed, altitude, and latitude/longitude but that's to be expected, even in modern cell phone GPS receivers. For a cheap little USB dongle, that I'd say that's pretty good! I should also mention that was indoors, so no doubt I'll have better luck outside. After that, I plugged it into the device I intended to use it with, a Raspberry Pi 4 being used as an amateur radio field computer. As soon as I plugged it in and configured it properly, I got a lock and an accurate grid locator, and more importantly I got accurate time down to the second, which is what I wanted since the Pi doesn't keep time by itself unless you use an RTC. Overall this USB GPS receiver works exactly as intended, and actually looks pretty nice all things considered. And for $15 it really can't be beaten. works very well, and I'll probably end up buying a few more in the future. 10/10

I needed a USB powered GPS receiver to attach to my astrophotography rig so I didn't have to keep putting in coordinates to my tracking software when I would move to a new site. This was perfect. Works perfectly. Read perfectly under Linux. Even worked indoors, where it lived upon arrival for a few weeks before being used in the field. So good, I bought a second one just to be able to synchronize time information on my home network.

Got it working with rpi 3b+ no problems. Have to use a USB extension cable though, as otherwise it hogs the neighboring port, though many usb devices are guilty of that.

I wanted to add GPS input to OpenCPN running on my Linux laptop. This fit the bill, was easy enough to install the drivers, and works just as it should. Despite no external antenna, it picks up and uses 6 or 7 satellites even indoors in my single-story home.

A USB GPS Dongle? Given the fact that most GPS antennas are 6 to 36 inches long made me skeptical. So I plugged it into mt PC, and after it loaded the appropriate driver, I ran u-center and starting seeing GPS data. But that's boring. What about a Raspberry Pi? Check the video. It's too easy. Plug the dongle into your Pi Make sure your copy of Raspbian is up to date. then, Open a terminal window and sudo apt-get install minicom use dmesg to verify the TTY assigned to the dongle (Mine was TTYACM0) then sudo minicom -b 115200 -o -d /dev/TTYACM0 and voila! You have GPS data. So, what could you do with it? Stash it in your kid's trunk to see where they go during the day. Stash it in your sales rep's car to see if they actually visited the customer. Check the laws of your state before you do, though.

No info included, did find an online resource, but, so far , after the third reading, seems to remain over my head, wont return it but will keep trying since it cost less than lunch at a drive-up restaurant.

Plugged it into a Win10 laptop and it just worked. No driver issues! Spits out a NMEA stream on a virtual comm port so you'll need software capable of using that data or use Putty to just look at the stream. Highly recommend.

"I received my item in a large envelope with no padding or wrapping, which was surprising to me. The packaging was not satisfactory at all. However, I was relieved to find that the dongle was not damaged. The problem was that it did not come with any instructions. I visited the website, but the instructions provided were not very helpful. After Googling for a while, I was able to find some YouTube videos that offered a few tips on installation. However, I found the videos to be underwhelming. I tried installing the software multiple times to get it to work with Android, which was supposed to be compatible, according to the seller's answer to a question. Unfortunately, I was unsuccessful. The product wasn't worth the trouble of returning, so I decided to give it to my dog as a chew toy."

数分、どうなることかと思ってみていたが、 無事、点滅し始め、受信を開始した。その後 毎日、重宝して使っている。

It worked as expected. GPS was reliable. Using with a Windows tablet computer to access GPS signal while on the road.

Excellent

First there are not instructions at all and can't find support. Pluged into the USB port and saw the com port but does not detect the GPS signal. Worked and then didn't work end result I am returning it.
