Trimble AgGPS® RTK base stations provide reliable +/- one inch pass-to-pass and year-to-year accuracy for agricultural vehicles that are using the AgGPS Autopilot™ automated steering system. Producers around the world have two options for obtaining an RTK correction signal - mobile base stations set up in the field and transported from farm to farm, or a permanent readily available signal from an established RTK Network.

If you are considering owning your own base station, consider these facts about mobile bases.  They are:

a) time consuming
b) easily stolen
c) a maintenance liability
d) lacking in precision accuracy
e) susceptible to interference  

For about half the cost of a mobile base station you can become a member of SPPA’s extensive network and enjoy the rewards of hassle free RTK guidance.
