Bridgewater VA | So to clear things up heres all the different activations. And ya I was kind of wrong SF-RTK supersedes SF3 from the 6000. The 7000 is just SF-1 or SF-RTK .
- SF1 – Activated on every StarFire iTC and newer receiver.
StarFire 3000 Receivers
- SF2 Ready – Receiver must be SF2 Ready to activate SF2 license and RTK.
- RTK Ready – Enables radio RTK. Receiver must have an RTK activation to activate M-RTK license.
-M-RTK License- renewable license or lifetime, unlocks ability to use RTCM, CMR, or
"JD M-RTK format" correction messages
StarFire 6000 Receivers
- SF3 Ready – Receiver must be SF3 Ready to activate SF3 license.
- RTK Ready – Enables radio RTK. Receiver must be RTK Ready to activate M-RTK license.
-M-RTK License- renewable license or lifetime, unlocks ability to use RTCM, CMR, or
"JD M-RTK format" correction messages
StarFire 7000 and 7500 Receivers
-SF-RTK – renewable license unlocks ability to use sf-rtk
-RTK – permanent license, unlocks ability to use radio rtk or use a m-rtk license, unlocks ability to use radio rtk, radio rtk uses NCT protocol
-M-RTK License- renewable license or lifetime, unlocks ability to use RTCM, CMR, or
"JD M-RTK format" correction messages
Heres the scoop on M-RTK: M-RTK is a NTRIP service from deere, the correction format is RTCM3 using iMAX delivery format from Leica. This will give you MSM messages (the main correction messages) plus some special SSR corrections, please note the correction format selected is JD M-RTK but under the hood this is just rtcm. This is is its own "format" because deere does some special stuff pushing ionosphere corrections not normally found in normal rtcm stream. Theres really nothing special about mrtk its just a regular rtk network using Leica GNSS Spider to serve rtcm corrections.
When you configure M-RTK you can use the cellular modem on the 7000 or you can select mobile RTK MTG in modem settings which uses your jd link modem where the display connects to the ntrip server and the msgs are pushed over can. Or you can select to configure the bolt on modem if you have no jdlink modem.
One thing is M-RTK is not a true VRS service generating synthetic OSR data like base data. I bring this up because if someone just has the m-rtk activation you might be able to use a different caster service if deere does not filter what domains you are allowed to connect to though the display or bolt on modem. This is probably unlikely to work but has anyone given it a shot? What does defiantly work is a hooking into the rs232 and pushing serial rtcm in then selecting correction type rtcm in the starfire config. This is how the cloudbase modem works.
Also, the stuff digifarm does is quite different, the beacon and elevate work like the bolt on rtk radio and send the same correction stream a starfire iTC would output, this is the legacy NCT protocol and appears to be GPS only. Sp the beacan 4.0 and 5.0 vs cloudbase work very differently.
