I am not sure, but I think I do. It would be steering a vehicle to keep it in close as possible to a vector of travel based on differential GPS signals. It would be used for gradiometer data collection for archeology. The more accurate the grid is sampled, the better. I think an alternative and possibly a smaller/less energy hungry solution might be based an Arduino board to control the servo, but I have way more experience programming in Linux than I do the Arduino... Plus, EMC already controls servos very well, so it would just be a matter of telling it to jog forward or backwards to keep on the vehicle on the vector. Trying to keep the development and hardware costs to a minimum.
