1. A heavy equipment vehicle, comprising:
- a locomotion system configured to move the heavy equipment vehicle;
a tool configured to manipulate a ground surface continuously as the heavy equipment vehicle moves;
a communication interface to provide communication with a plurality of position measurement devices; and
a control system comprising a processor, a non-transitory storage medium, and a set of instructions executable by the processor, the set of instructions comprising;
instructions to receive position data from two or more position measurement devices, including a first position measurement device and a second position measurement device;
instructions to control operation of the tool based on determined positions of the tool and a model stored on the non-transitory storage medium;
instructions to determine a first position of tool based on position data received from the first position measurement device;
instructions to transition from the first position measurement device to the second position measurement device without interrupting movement of the heavy equipment vehicle or manipulation of the ground surface and without introducing a discontinuity in the manipulated ground surface greater than a specified threshold value; and
instructions to determine a second position of the tool based on position data received from the second position measurement device.

Abstract
Novel tools and techniques for controlling heavy equipment vehicles, such as tractors, graders, road-forming machines, and the like. Some techniques allow a control system of a heavy equipment vehicle to transition from receiving position data from one positioning device to receiving data from another without ceasing operation and/or while limiting any resulting discontinuity in a manipulated ground surface to within acceptable tolerances.

22. A control system for a heavy equipment vehicle, the control system comprising:
-
one or more processors; and a non-transitory computer readable medium in communication with the one or more processors, the computer readable medium having encoded thereon a set of instructions executable by the computer system to; receive position data from two or more position measurement devices, including a first position measurement device and a second position measurement device; control operation of a locomotion system of the heavy equipment vehicle and a tool of the heavy equipment vehicle to manipulate a ground surface continuously, based on determined positions of the tool and a model stored on the non-transitory computer readable medium; determine a first position of the tool based on position data received from the first position measurement device; transition from the first position measurement device to the second position measurement device without interrupting movement of the heavy equipment vehicle or manipulation of the ground surface and without introducing a discontinuity in the ground surface greater than a specified threshold value; and determine a second position of the tool based on position data received from the second position measurement device.

23. A method, comprising:
-
manipulating a ground surface with a heavy equipment vehicle, the heavy equipment vehicle comprising; a locomotion system configured to move the heavy equipment vehicle; a tool configured to manipulate a ground surface continually as the heavy equipment vehicle moves; a communication interface to provide communication with a plurality of position measurement devices; and a control system configured to control operation of the heavy equipment vehicle; receiving, with the control system, position data from two or more position measurement devices, including a first position measurement device and a second position measurement device; controlling, with the control system, operation of the locomotion system and the tool based on determined positions of the tool and a model stored on the non-transitory storage medium; determining, with the control system, a first position of the tool based on position data received from the first position measurement device; transitioning, with the control system, from the first position measurement device to the second position measurement device without interrupting movement of the heavy equipment vehicle or manipulation of the ground surface and without introducing a discontinuity in the manipulated ground surface greater than a specified threshold value; and determining a second position of the tool based on position data received from the second position measurement device.
