Farmers around here use GPS guided equipment to guide their farm equipment.  It is possible to put fertilizer in one inch strips around the field and later go back and plant in the same strip.  Some use a reference transponder to increase accuracy.  Others seem to be able to use references on nearby cell sites.

Would like to know more about the algorithms that allow this accuracy.
