I've attached the spreadsheet from the link.Unfortunately, the Forest Service Website went offline (maybe this thread caused so much traffic that it broke down? ;) )
There are some uBlox modules that can be had for under 10$US from AliExpress. These are as barebones as you can get. They're just a GPS receiver, nothing more. You need power, you need something to read the output. On the other hand, if you're into experimenting they're dirt cheap. I used on to build a very basic data logger using a $2 microcontroller to write to a flash card. Some of the cheap uBlox modules can output carrier phase data so you could use RTK to get sub-meter resolution, at least in theory. Doing this in real-time in the field strikes me as hard, but you could collect the data and post-process after the fact to get accurate field positions.Furthermore, I stumble upon an article about a module with u-blox chip. https://www.sparkfun.com/products/16481
Does anyone have any experience with modules like this and what else is needed? The description of all the stuff leaves me a bit puzzled.
