  "account": "RTK receivers on farm machinery provide millimeter-level accuracy, but without corrections, they can only place themselves within a meter or two. There are three ways to get corrections: network RTK (NTRIP), your own base station, or PPP/satellite service. Network RTK uses a network of permanent reference stations streaming corrections over the internet, and functions well with reliable mobile coverage and a station within 20-30 km. Your own base station is a fixed GNSS receiver at the yard or on a mast that sends corrections over UHF radio or the internet. It's ideal for patchy coverage and no correction subscription, but requires a rigidly mounted base with a clear sky view and proper coordinates. PPP/satellite correction services use precise orbit and clock corrections delivered by satellite or over the internet, working well for large remote fields needing 10 cm accuracy. Farms often combine base stations for main fields with network RTK or PPP as backup elsewhere.",
  "summary": "An RTK receiver on a tractor, sprayer or farm robot is only as good as the corrections it gets. The receiver measures satellites to within millimetres of carrier phase, but without corrections it can only place itself to within a metre or two. The correction source decides three things: how accurate your lines are, whether they repeat next season, and what happens in the corner of the field with…",
