The signal used for GPS is being transmitted on the L2 Band, it is scheduled to be decommissioned on Feb 1, 2021, that is subject to discussion but as a dealer that’s what we are told.
You are being fed a line. The current schedule for change is quoted below.
"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 with fully functional navigation messages. Barring a
national security requirement, the USG does not intend to change these
signal characteristics before then. The availability of 24 satellites
broadcasting the L5 signal is estimated to occur in 2027. Maintaining the
legacy signal characteristics for the stated period of time 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 L2C by 2023.
Civilian users of GPS are encouraged to start their planning for transition
It now appears that the US government is planning to keep all existing GPS signals functional until sometime in 2029. Good news for those of us using non JD legacy GPS positioning systems.
The changes JD is making to the Starfire correction signals appear to be independent of the planned changes that the US Government has scheduled for the GPS signals.
