TraceNav - 9/19/2025 20:13 Yes, I did push all my notes though chatgpt and yes it did slopify some stuff on that first post, all the stuff that reply is copied right out of deere docs on SF activations and the m-rtk stuff is from my own experimentation. I did listen to both those episodes from everything ag before posting anything on here and that was a huge help on info for the gen 1. Heres the other sources used- details AR methods used in navcom engine, mentions NCM2000 https://www.deere.com/assets/pdfs/navcom/White%20Papers/a_fast_ambig... Evidence early SF1 and SF2 used RTCM SC104: https://content.u-blox.com/sites/default/files/products/documents/GP... SF3 and SF-RTK has to be some sort of PPP RTK so something had to change like using RTCM 3 SSR msgs or some bespoke SSR protocol, PowerGPS- Mid 90s multiband reciver built by Sokkia in colab with navcom- https://www.ion.org/publications/abstract.cfm?articleID=631 iTC manual, 3000 manual, 6000 manual, 7000 manual was used The itc manual puts sf2 pass to pass at 10cm wile 3000 OPERATOR'S MANUAL StarFire RTK900 MHz Radio OMPFP11348- This states the rtk radio 900 works with original starfire, itc, 3000, etc https://bmotion.com/ https://bmotion.com/navcom/eng_serv.htm The designer of the original navcom site, still hosting a copy of the site from early 2000 The Gen 1 being L1 L2 is it uses the same enclosure between the NCT2000 eval kit, Gen 1, and Gen 2, the eval kit and the Gen 2 are for sure L1 + L2, in the podcast they stated that the Gen 1 used omnistar, however omnistar stuff was L band. Take a look at the old navcom site, that thin lip on the Gen 1 is probably the C band antenna and almost nothing is documented about this C-band correction service. @4wdaaron any chance a owners manual is floating around for the gen 1 or the gen 2 starfire? Would be great to find out if the Gen 1 supported RTK and if it was the same 10+2 channel receiver stack.
