    GPS accuracy boost for android

    With the low milk prices we are taking on more of our own tractor work of late. Mostly fertilizer spreading and Spraying.

    We do not have a GPS and our sprayer doesn't have a foam marker. I have found a handy and user friendly gps app that tells you where you have been in a paddock.

    PROBLEM! it's not super accurate I would say it's within 1m judging by the green spots in a sprayed paddock.

    Are there plug in or Bluetooth GPS antenna that will increase my galaxy S7 GPS accuracy to a use able level say 20cm?

    If not I guess I'm out to buy a lightbar GPS but would like to save $600!

    General GPS Accuracy is stated for our stuff at + or - 10m but is generally + or - 5m or less. To get the type of accuracy you are after requires a lot of special stuff. When I worked offshore as an ROV Pilot we typically had + or - 5cm but had a lot or axillary equipment such as fixed reference stations and differential GPS

    There are a couple of things you can do that will make a minor difference.

    Does your phone support GLONASS (russian gps) because if it does then it's got more satellites to lock onto. This app claims to download the GPS assist data and make your lock faster and more accurate.

    You can get external gps devices that connect to your phone via bluetooth but I am not sure that will help that much.

    You could always do it the way we did before gps, pacing out and using marker posts, of course you could just buy a add on foam marker, over the life of the machine you would pay for it in saved chemicals and time.

    Your phone is designed to send texts and take/send pictures of your genitalia.

    You need specialized gps to do what you want accurately.

    You could reduce your step distance and accept some more overlap if you don't want to upgrade to purpose built gear.

    If you put a gps in there there would be no windscreen to see out! Looks like a full cab already

    I could build a foam marker pretty easy with a 12v air compressor and a bucket. Would not work for fert. As much as we do it will be worth buying a lightbar type gps but I was hoping to save some $
