1. A system for determining the relative position of a second vehicle in relation to a first vehicle, wherein the first vehicle and the second vehicle include equipment to jointly perform an operation on a field, the system comprising:
- 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 or uniform reception modes; and
a reception device for receiving corrective data from reference stations in known locations, wherein the control device is responsive to information regarding quality of the corrective data to improve accuracy of the position sensing devices, wherein the control device is operable to prompt the position sensing devices to use the same reception mode or the uniform reception modes for the corrective data.

Abstract
A system for determining the relative position of first and second farm vehicles, each equipped with a satellite-supported position sensing device. A data transmission link transmits position data between the vehicles, and a computer on one of the vehicles determines data with respect to the relative position of the vehicles. A control device responsive to satellite signal quality assures that the two position sensing devices operate in the same reception modes for improved accuracy.
