We are looking at using some Windows based rugged tablets in the field for doing on-the-spot data entry that also includes storing GPS coordinates. So we would go to the asset, capture all the information (including current GPS coordinates of the tablet) in a custom app we've already developed and then later import this data into our existing GIS system.
We'd like the receiver to have 'sub meter' accuracy. I've looked around a bit and found things like the Arrow Lite by EOS and the Geneq SXBlue II GPS Receiver but these are both ~$2,000. In fact all sub meter GIS grade GPS receivers I've seen above the $2000 mark. Are Map grade GPS receivers accurate enough for what we want to do and would their price be significantly less than $2000?
