RTK Facet L-Band

The accuracy on RTK float is hard to define, it’s probably <0.1m but there’s not much documentation putting numbers in that state.

Also, do you have any base stations that use L1/L5 bands?

Yes, the NEO-F9N (https://www.sparkfun.com/products/23288) is capable of base and receives L1/L5 and can output RTCM corrections which include L5.

For the NEO does that connect to my Facet L band? I believe that was the piece needed to turn my device into a base station?

The NEO-F9N (https://www.sparkfun.com/products/23288) is currently a breakout board only that would require an external micro to do useful things.

Adding the NEO-F9N to the Facet is not (really) possible.

Your RTK Facet is capable of being a base station without modification, but the RTK Facet is not capable of receiving the L5 band at this time.

Can you provide the base station instructions?

SparkFun has lots of docs on their website full of information about setting up an RTK base. In addition to the above link, check out their tutorials.

There is a lot to learn, brew up a pot of coffee and clear your calendar. :slight_smile:

Looking at the excel sheet i exported. There is a Fix ID column. Can you explain that? The values i get are only 1 and 2

In SW Maps, the position bubble will turn from Blue (regular GNSS fix), then to Orange (RTK Float), then to Green (RTK Fix). This is what i found in the guide but i also at times get a red dot when connected to the device,

Actually, my experience shows that in “Float” the accuracy is quite poor, many times over 3 ft, even if the reported accuracy is 5-10 cm at the exact same time.
I’d rather store a DGPS number than a Float number.
While in float, you can store points and you’ll see what I am saying.
The unit seems to wander aimlessly until it “fixes”. The process reboots over and over again until it “fixes”. That’s what you want.
Yesterday, I was watching the UTM coordinates while floating, and they jumped instantly by 50cm when the fix was achieved. All of that with 5cm reported accuracy in Float.
I work a lot in trees and quite often a fix is never achieved. Sometimes, you come back a different day and it works.
My surveyor has a Trimble system ($$$) and it works better than the Facet. But in 99% of the time, I am OK with what I get.
Their Float process is different, and does not seem to wander nearly as much.
