Why is my GPS not accurate?

Carmen -

Sometimes after recording a zone boundary, the boundary can appear incorrect on the map.

This can happen if you don't have sub-meter GPS precision when recording a boundary or if you walk too fast when setting up the boundaries.

It's better to redo the zone boundaries rather than mapping the course all over again. When you set a new boundary on an existing zone, it overwrites the old one. 

Make sure the GPS indicator, in the bottom left corner of the screen, has a green badge that says 9 or higher. This is the number of GPS satellites the POGO currently sees. If you have less than 9, your GPS location may not be completely accurate.  

When you are taking location samples, it is good practice to pause a second after every sample. POGO receives satellite signals about every 2 seconds. So you want to be sure the POGO is not lagging behind you if you are moving very fast.
 
Here are some general tips on getting the best GPS precision:
  • Always keep the POGO on with a view of the sky throughout the day, or at least until all sampling is completed for a particular session of sampling all zones. We have seen many users mount the POGO in a length of 2” PVC irrigation pipe to their cart. It makes for a nice transport system and protects the POGO very well.
  • Walk at a leisurely pace when setting your boundary. Tap the Get GPS button about every one to two seconds when walking the perimeter.
  • When taking soil samples or when recording the position of a property feature (sprinkler, valve, drain, etc.), pause a moment or two before taking the sample to allow the precision of the POGO's GPS to be as accurate as possible.
  • Even if you are showing 9 or more satellites, interference from wires, trees, buildings, and the time of day can show variance as the position of satellites can skew a bit in the sky. These are normal variations in GPS are not due to the performance of the POGO.

If you follow the above tips, you should have sub-meter accuracy at nearly all times.

To redo a recorded boundary, go to Property Features in the app and then Zone. Tap the zone you wish to redo a boundary for.
