Abstract: An irrigation system broadly comprising a number of irrigation spans, an end gun, an end gun booster pump assembly having a booster pump and a booster pump motor, and a control system including a system controller and a variable frequency drive (VFD) for controlling the end gun pump motor. The system controller determines a desired end gun throw magnitude according to sensor inputs, irrigation system location information, user inputs, and/or other data and sends to the VFD a signal representative of an instruction to increase or decrease an electrical motor input for the booster pump motor. The VFD effects a booster pump motor speed via the electrical motor input so that the booster pump steps up water pressure to the end gun according to the desired end gun throw magnitude.
