SparkFun RTK Facet L-Band Base for RTK Drone

Community Projects
1

Hi All,

I am really interested in the SparkFun RTK Facet L-Band ($1500) for drone mapping work. I have been in GIS mapping for over 25 years and only require around 6 - 12 inch relative accuracy. I really like that Sparkfun includes the first year subscription for corrections through PointPerfect. I have an Auel EVO II Pro Enterprise with RTK. When the RTK unit is attached (No CORS base) I get around 2.5 - 7.5 feet of relative accuracy per WebODM quality reports. This works for some projects, but I would like a more consistent solution.

Some things that concern me before I purchase.

  1. Not one of the reps on YouTube mention using this unit as a GNSS base station for an RTK equipped drone.

  2. Can this unit be connected to a RTK drone using Wifi or Bluetooth?

  3. Can an RTK base station use FIX when connecting to an RTK drone (rover)? I haven’t heard of RTK to RTK.

  4. Can the export files be converted to RINEX easily for PPK workflows?

  5. Can the current export files be uploaded to National Geodetic Survey OPUS?

  6. When using PPK workflow, can user enter state plane coordinate system or is output always WGS84 with ellipsoid elevations?

  7. What is the relative accuracy without the PointPerfect subscription?

Regards,

Gerry

This post seemed to have been missed - apologies. Feel free to poke around either the hookup guide https://learn.sparkfun.com/tutorials/sp … okup-guide or the manual https://docs.sparkfun.com/SparkFun_RTK_Firmware/intro/ that has essentially all of the use-specific info we have available

  1. The Facet can be used as a Rover or Base

  2. Either :slight_smile:

  3. Sure - the Facet can be receiving RTK data over mobile hotspot (or other) wholly separate and you could calibrate 1 vs the other if necessary

  4. Yes https://docs.sparkfun.com/SparkFun_RTK_ … x-to-rinex

  5. I would assume so; I mostly deal with the product side of things…but if it’s just a mode of integrating the data I don’t see why it wouldn’t work

  6. Run through this https://docs.sparkfun.com/SparkFun_RTK_ … 3-to-today

  7. ~1cm https://cdn.sparkfun.com/assets/a/8/5/f … 044850.pdf

Hope this helps!

TS-Russell,

Thank you for your response. I really do hope this unit works as intended.
