GNSS and optical guidance and machine control
First Claim
1. A guidance system for a vehicle having optical sensors and a working component attached to the vehicle having optical targets, the guidance system comprising:
- a guidance computer to;
receive inputs from the optical sensors associated with optical signals generated from the optical targets on the working component; and
calculate at least one of a roll (X) directional misalignment, pitch (Y) directional misalignment, or yaw (Z) directional misalignment of the working component in relation to an orientation of the vehicle based on the inputs from the optical sensors.

Abstract
A global navigation satellite sensor system (GNSS) and gyroscope control system for vehicle steering control comprising a GNSS receiver and antennas at a fixed spacing to determine a vehicle position, velocity and at least one of a heading angle, a pitch angle and a roll angle based on carrier phase position differences. The system also includes a control system configured to receive the vehicle position, heading, and at least one of roll and pitch, and configured to generate a steering command to a vehicle steering system. The system includes gyroscopes for determining system attitude change with respect to multiple axes for integrating with GNSS-derived positioning information to determine vehicle position, velocity, rate-of-turn, attitude and other operating characteristics. Relative orientations and attitudes between motive and working components can be determined using optical sensors and cameras. The system can also be used to guide multiple vehicles in relation to each other.

6. A navigation computer configured for controlling a vehicle and auxiliary equipment, the computer comprising:
-
a processor to; identify a fixed separation baseline between a first set of antennas on the vehicle; determine multiple variable separation baselines extending between the first set of antennas on the vehicle and a second set of antennas on the auxiliary equipment, the variable separation baselines having variable lengths corresponding to relative variable orientations of the vehicle with the auxiliary equipment; and compute positions of the vehicle and the auxiliary equipment based on the fixed separation baseline and the variable separation baselines, wherein the variable separation baselines identify a roll (X), pitch (Y), or yaw (Z) of the auxiliary equipment relative to a roll (X), pitch (Y), or yaw (Z) of the vehicle. - View Dependent Claims (7, 8, 9, 10, 11, 12)
