1. A system comprising:
- a mobile earth moving machine, comprising;
a working implement configured to contour soil,a position determination system, wherein the position determination system is configured to determine a geographic location of the mobile machine based on received satellite navigation signals; and
one or more standoff targets, placed in or near an area where the position determining system produces geographic location determination of reduced accuracy as a result of insufficient satellite navigation signal quality,wherein the mobile earth moving machine further comprises;
a sensor configured to automatically sense a standoff target signal from one or more of the standoff targets,a processor, configured to, in response to the position determining system receiving satellite navigation signals of insufficient quality, determine location information for the one or more standoff targets, wherein the processor is further configured to determine a distance and a direction between the mobile machine and each of the one or more standoff targets, wherein the processor is further configured to determine a position for the mobile machine, wherein the position for the mobile machine is determined based on;
a) the location information for each of the one or more standoff targets, andb) the distance between the mobile machine and each of the one or more standoff targets in conjunction with the direction between the mobile machine and each of the one or more standoff targets, andan earthmoving implement configured to contour soil, wherein the processor is further configured to determine a position of the earthmoving implement according to the position of the mobile machine as determined based on either the satellite navigation signals or the location information and the distance between the mobile machine and each of the one or more standoff targets.

Abstract
A method and system for auto recognition of at least one standoff target to determine position information for a mobile machine. One example automatically scans for at least one standoff target. A location for the at least one standoff target is determined. In addition, a distance and direction between the mobile machine and the at least one standoff target is generated. The location information for the at least one standoff target and the distance and direction between the mobile machine and the at least one standoff target is utilized to provide a position for the mobile machine.
