Hi guys - I just saw your great blog entry on "GPS Testing with Bad Elf GNSS Surveyor". We are a Google Apps shop and desperately trying to convince our staff "it's okay" to use Android tablets - and in fact there are other tablets in the world besides iPads. But everything we read is about iOS, iOS, iOS. haha

Do you have any tips or suggestions for GPS accuracy on Android (e.g. Nexus 9) tablet use? Any products you have tried that gave 1 meter accuracy? Do you have to use a 3rd party tool to override the built-in GPS like this Garmin article suggests?{924b5370-b8f3-11e2-4124-000000000000}&locale=en_US

    Hello Todd,

    Thanks for reaching out to us.

    GPS accuracy will vary greatly depending on the amount of open sky visible to the device. We have found that the third party bluetooth 3-meter GPS units, like the Glo, provide more reliable location information when the sky is obstructed. Additionally, letting the device settle in on a location also helps a lot. So if keep the device still in a single location for 30 sec to a minute your accuracy will increase.

    GPS accuracy on all modern devices (both Android and iOS) are pretty comparable to one another. To get below 1 meter accuracy you will need an external device. We have has some limited testing with XSBlue's bluetooth GPS device and have users that use it will success, there devices give sub meter accuracy. Bad-elf's device was close to a meter and has a more attractive price point, they are going to release a new firmware update and we will test the device again to see if we can get it accuracy closer than a meter. We are in the process of testing EOS's Arrow 200 GPS receiver, which claims centimeter accuracy, so far the device looks promising.

    With Android devices you will have to use a third party too to override the built in GPS.

    Wow. 1cm accuracy. And supports both iOS and Android. I'm looking forward to hearing your review of the Arrow 200. Thanks so much for answering!
