West Union, Illinois | The official explanation from 2017 Federal Radionavigation Plan 3.2.8 Discontinuation of Codeless and Semi-Codeless GPS Access3 The USG commits to maintaining the existing GPS L1 C/A, L1 P(Y), L2C, and L2 P(Y) signal characteristics that enable codeless and semi-codeless GPS access until at least two years after there are 24 operational satellites broadcasting L5. Barring a national security requirement, the USG does not intend to change these signal characteristics before then. Twenty-four satellites broadcasting the L5 signal is estimated to occur in 2024. This will allow for the orderly and systematic transition of users of semi- codeless and codeless receiving equipment to the use of equipment using modernized civil-coded signals. Note that it is expected that 24 operational satellites broadcasting L2C will be available by 2020, with the corresponding ground segment control capability available by 2023, enabling transition to that signal at this earlier date. Civilian users of GPS are encouraged to start their planning for transition now.
Or to use words I understand, from https://www.btiequip.com/blog/starfire-itc-service-is-going-away--17916 This is not an action caused by John Deere Company but rather a result of the government updating satellites that John Deere utilizes for its signal. These newer satellites will be operating at a different frequency which the iTC receiver will not be able to recognize after January 1, 2021 when the change occurs. If you are currently using a John Deere 3000 or 6000 receiver they will not be affected by this frequency change.
Or from Sloan's: https://sloansupport.com/2018/07/16/attention-all-john-deere-starfire-itc-owners/ We received word from John Deere that effective Jan 1, 2021, Starfire ITC GPS Receivers will no longer be able to receive the SF1 or SF2 corrections required for machines to Autotrac. ITC receivers will still be able to show coverage, document, and be used for sectional control (in some cases) using the WAAS signal. This was not a decision made by John Deere or INMARSAT (the company that provides the bandwidth for our SF1 and SF2 correction signals). This change is happening because of a government satellite update where new satellites broadcasting the L5 signal are replacing the older signals. The hardware inside an ITC receiver will not allow it to receive the newer data. Starfire 3000s and 6000s are not affected by this change.

Anyone know if this is true?
