1. System for determining the relative position of a second farm vehicle in relation to a first farm vehicle, wherein the first vehicle and the second vehicle include equipment to jointly perform an operation on a field, the first vehicle including a computer and a first satellite-supported position sensing device and having a receiver for receiving signals from several satellites in one or more reception modes and structure for providing first position data for the first vehicle, the second vehicle including a computer and a second satellite-supported position sensing device for receiving signals from several satellites in one or more of the reception modes and structure for making position data of the second vehicle available, a data transmission connection between the first vehicle and the second vehicle for transmitting the position data of the first vehicle to the computer of the second vehicle or vice versa, the computer of the second vehicle operable to determine data with respect to the relative position of the second vehicle in relation to the first vehicle based on the position data of the first vehicle and the position data of the second vehicle, a control device for receiving signal quality information, wherein the position sensing devices of both vehicles provide information quality signals indicative of the quality of the signals of the respectively received satellites to the control device, and wherein the control device is responsive to the information quality signals such that the two position sensing devices operate in the same reception mode.
