Patent ID: 11061144

Abstract:
A system and method for providing power and alignment control within an irrigation system having at least two spans and a drive system for moving the spans. According to a first preferred embodiment, the present invention includes a method for maintaining the alignment which includes the steps of: receiving a first set of Global Positing System (GPS) location data and second set of Real-Time Kinematics (RTK) error data; comparing the first set of GPS location data with the second set of RTK error data; calculating RTK error correction data; transmitting RTK error correction data to the intermediate drive towers and the last drive tower; calculating the location of the last drive tower using GPS data and RTK error correction data; calculating a straight, center line between the center pivot and the last drive unit; calculating the relative distances between each intermediate drive tower and the calculated center line using a linear regression algorithm; and controlling the average speed over time of each intermediate drive tower to reduce distance between their current locations the calculated center line The present invention provides a system for aligning drive towers within an irrigation system.
