Subject: RE: Satellite changes


GPS satellites are slowly switching over to new frequencies as they are replaced, yes. Originally this was to be done by now (hence the 2021 deadline Deere gave its customers). However the rollout has gone more slowly than originally planned. It will now be no earlier than 2024, more likely 2026 when the majority of GPS satellites will be using L5 bands and the older signals will start to be retired. I don't think this change will impact any receiver bought in the last 10 years. Really old receivers will eventually be impacted. Like ancient handheld units, and the Deer iTC won't be able to even do WAAS eventually.

Other satellites besides GPS are also changing frequencies as well. I know some satellite TV providers are changing this year. I believe all of this including GPS changes are because of frequency reallocations that gave a bunch of spectrum to terrestial wireless data services (read cell companies). Unfortunately I cannot find a good summary of these changes.
