i'm trying to make an android app that collects data field in high accuracy, since the phone native GNSS doesn't provide highly accurate coordinates, i want to use Coordinates provided by a real GNSS device and transfer them to my app.

any way to do that using a real GNSS stand-alone device ?

    Are you able to export the info collected from the GPS unit into a SQLite database? If so, maybe the user can download that onto the device and read it at runtime.

  • you may want to look at the open source project that we built that does that: github.com/amigocloud/amigoclient Feb 19, 2016 at 20:47

    Be aware that both Android devices and "real stand-alone GPS devices" both have a wide range of accuracy, largely depending on the quality (and cost) of internal components. In some cases Android devices will produce faster and better quality fixes that low end standalone GPS due to the use of assisted GPS. Feb 19, 2016 at 21:26
  • I'm using Trimble R4 GPS, i think it is one of the most used devices in topography due to its accuracy.
