It seems like installing the base station for differential GPS would be easier than installing the electronic fencing descried in the article.

- pjc50 12y agoYes, although it may be more expensive (I suspect you have to license a whole pile of patents)
- oh_sigh 12y agoEasier, maybe? But it would cost tens of thousands of dollars and be subject to even more regulations, so I don't think that is a good solution.
- 0xffff2 12y agoWhy would it be subject to more regulations? You just need two GPS receivers and a way to link them (e.g. WiFi).
- oh_sigh 12y agoSorry, but I don't think you know how differential GPS works. It is not just using two GPS devices and averaging their location. Wikipedia is a good place to start: http://en.wikipedia.org/wiki/Differential_GPS http://en.wikipedia.org/wiki/Differential_GPS
