Southeast Minnesota RTK Network

SEMA Equipment | RTK Network 

RTK Locations Interactive Map:

SEMA Equipment has invested in a robust network of RTK towers covering much of southeast Minnesota. SEMA owns, maintains and supports the system, which lowers the investment cost for growers. RTK utilizes a local, ground-based reference station that transmits the high-accuracy 1 inch corrections to a machine StarFire receiver via RTK radios. Due to the proximity of the base station to the machine, all satellite drift is eliminated, and the position is repeatable.

Annual Subscription

An annual subscription to SEMA Equipment's RTK Network is $1,050 per receiver. This is the same cost for an annual subscription to SF2 signal, which provides 2-4 inch non-repeatable accuracy.
