I have no real knowledge of this, but maybe they were relying on that satellite to transmit DGPS corrections for their region or something, to improve accuracy. Edit: Found this while replying to a now-deleted comment: Even if it's not exactly DGPS, it seems like it's some kind of accuracy-improvement service: https://www.abc.net.au/news/rural/2023-04-18/inmarsat-i-4f1-satelite-outage-asia-pacific-gps-farms/102234678 https://www.abc.net.au/news/rural/2023-04-18/inmarsat-i-4f1-...: > He has got a workaround for now, using the old free-to-air GPS that is a lot less accurate, but he said he was disappointed with the lack of information on the outage. IIRC, regular GPS positions have an error of at least a few meters, which is not good enough if you're trying to plant crops.
