- Make sure this fits by entering your model number.
- Works with Windows,Andorid,Linux,Raspberry pi.Support Google Earth.It can not work with IOS system.
- Raspberry pi and linux no need driver.
- The default output is the product GPs protocol data. You can test the software or serial commands to modify switch PS / GLONASS protocol data.
- Note: This dongle only can work outdoor. If you want to let it work indoor, you need have GPS amplifier. Otherwise the GPS can not lock.
- If you need some driver links and using videos for VK-172,Please contact us.

- For a $14 gps this thing is kind of amazing. I was able to get a lock with very little difficulty hanging it out the window of my place in a downtown area not conducive to good reception.I\'m using it on a Raspberry Pi. The device is automatically recognized as /dev/ttyACM0. You can do a tail -f of that device and see the NMEA output after you plug it in.If you want to set it up as an NTP source, here are some steps to follow:# Update sourcessudo apt-get update# Install the gps daemon, libraries and NTPsudo apt-get install gpsd gpsd-clients python-gps ntp # to install the gps daemon and the ntp server# edit the gpsd config filesudo vi /etc/defaults/gpsd# Add/modify the following lines to the file. They may already exist so just modify. These specify the device explicitly and NTP won\'t work without the -nDEVICES=\"/dev/ttyACM0\"GPSD_OPTIONS=\"-n\"# save/quit the above, then edit the ntp configuration filesudo vi /etc/ntp.conf# Add these lines to ntp.conf:# gpsserver 127.127.28.0 minpoll 4 maxpoll 4 preferfudge 127.127.28.0 time1 0.000 refid GPS stratum 15# save/quit then rebootOnce that\'s all done you should be able to type:cgps -s...and see a full screen display with the GPS attempting to lock or locking up. If you get a timeout check your work and connectionsIf NTP is working you should be able to type:ntpq -p...and you\'ll see a line in the resulting text that looks something like this:*SHM(0) .GPS. 15 l 14 16 377 0.000 3.505 3.556If \"poll\" and \"reach\" are zero it\'s not working.Hope this helps!
- I have been buying and testing just about every little GPS module with Ublox-8 you can buy. This turns out to be the wild west, with many offerings not working very well at all, some seemingly counterfeit imposters, and a few that work great. I have tried several with integral antenna thinking that would be ideal, but none of those perform as good as this one. I do all my testing indoors on my kitchen counter, as they will all somewhat work well outside under ideal conditions and it\'s more difficult to spot the few dB of difference that really might matter under more stressful actual usage. Right out of the box this recevier came up within 1-2 minutes tracking lots of GPS and Glonass satellites in 3D tracking, and quickly follows with 3D/DGNSS SBAS tracking. Fantastic.This receiver, whether in the middle of my house or by a window, averages typically within ~3-5m accuracy with ~7.5m short term deviations. In the attached picture, this module is the lower plot, and I think this may actually be a worst case scenario--on a window sill facing South, it was pretty blind to half the sky, whereas in my kitchen it had weaker signals all around but some through windows in all directions (note the deviations are much smaller East/West, rather than circular as in my kitchen). Many modules do MUCH worse than this, this is pretty much the best. What a little gem this module is, top performance with the included antenna, flexibility to change to a different antenna or longer cable to remote it if you want to.The next best performers are these two, probably identical:https://www.amazon.com/gp/product/B07H9K6HFB/ref=oh_aui_search_asin_title?ie=UTF8&psc=1https://www.amazon.com/gp/product/B0716BK5NT/ref=oh_aui_search_asin_title?ie=UTF8&psc=1These are fantastic, come up super fast every time and go quickly to 3D/DGNSS, booming signals, and tight trcking--in my kitchen (2 floors blocking above). The \"DIYmall Micro GPSV5 GPS Module GNSS HMC5983 Saw LNA Triple Band Antenna ANT\" performed slightly better running side-by-side testing, possibly because the similar sized antenna wasn\'t so close to the laptop.The best module with integrated antenna was this one: https://www.amazon.com/Receiver-Navigation-Sensitivity-Betaflight-Geekstory/dp/B07P7N9CV6/ref=sr_1_fkmrnull_5?keywords=geekstory+m8n&qid=1551654303&s=gateway&sr=8-5-fkmrnullIt is the top receiver in the attached performance plot, not quite as good as this one but really quite good considering the size and weight.Most of these receivers have little documentation, but at least they all have silkscreen markings so you know how to hook them up. I will mention this next receiver because it had no markings, and no easily found documentation, the only clue being a red wire (with 5 black wires)--guess what, the red wire ISN\'T power, so I probably blew it up. a real shame, as it looks authentic and really well made, but buyer beware!: https://www.amazon.com/gp/product/B077YHPLGP/Oh, and lastly, don\'t even waste your time with the Adafruit \"Ultimate GPS Receiver\", it was one of the worst performers of all (more like a Ublox-6).
- I bought this because many of the comments about this product said it was easy to use, including with an Arduinio, except the fine print says it\'s a replacement part for something NOT Arduino, so there are no official schematics, API, or sample code to copy on the company\'s website (or anywhere else) to be able to use it on an Arduino. I also noticed (too late) that some of the photos by commenters was not of the product listed or received, and failing to notice that is a mistake I should not have made. Nevertheless I took an educated guess anyways that it was an ASCII based CLI, downloaded ADAFRUIT_GPS from GitHub, and got it to work (you still need to write real life code to do what you want it to do though but it is a good start). The wiring to make this work on a Arduino Uno can be found by looking at the code and looking at a lone jpg for the pinout of the provided GPS cable:BLK --> GNDRED --> 5V (or 3.3V)BLU --> 8GRN --> 7The code does need to be changed because the default baud rate is 9600, and there is no documentation of how to program the GPS item. The only code that works is for the files prefixed with \"GPS_Software\" (don\'t use \"GPS_Hardware\" or \"GPS_I2C\") and change one line, the line that says \"Serial.begin(115200);\" and change it to \"Serial.begin(9600);\", then open a Serial Monitor from the Arduinio IDE and watch it work.Not recommended for beginner programmers
