CONTROL GP-SECONDARY STEERING 1326640 - Caterpillar

Pan - With auto pan on, when the machine nearly reaches the edge of the screen, the map is moved and redrawn so the machine is near the opposite edge of the screen and heading toward the center.Avoidance Zone - The avoidance zone is an area on the construction site that the machine should not enter. This area is shown on the display as a closed, straight sided polygon.Base Station - A base station must be used with the Cat Grade Control System. The radio communicates with the system. This station transmits CMR messages to the machine to improve position accuracy.Compact Measurement Record (CMR) - A satellite measurement message that is broadcast by the base receiver. The RTK GNSS receivers use CMR to calculate an accurate vector from the base to the rover.Cross Slope - The average grade or slope of a parcel or area expressed as a percentage of vertical difference in elevation to the horizontal distance. A level surface has a cross slope of zero.Dialog - A screen that allows the operator to enter text or numbers, or select options.Differential Global Positioning System (DGPS) - A technique that uses GPS satellite technology and radio telemetry to calculate a position to better than 1 m accuracy.Digital Terrain Model (DTM) - An electronic representation of the design in three dimensions. TINs and grids are two types of DTMs.Firmware - Software that is stored in read-only memory (ROM) or programmable ROM (PROM). Firmware runs the CatGrade Control System.Global Navigation Satellite System (GLONASS) - Russia owned satellite system used to provide GNSS position.Global Navigational Satellite System (GNSS) - A technique that uses satellite technology from certain satellite constellations to calculate an accurate three-dimensional position.Global Positioning System (GPS) - United States of America owned satellite system used to provide GNSS position.Gridded DTM - A gridded DTM is a rectangular grid of points representing a three-dimensional surface. Also see DTM.Heading - The direction in which the machine is moving.Light Emitting Diode (LED) - A small, bright, colored light that is used in electronic components.Load - 1. To put data onto a USB flash drive, so that the flash drive can be used. 2. To copy data into the display from the USB flash drive. 3. To select a file for use.Northing/Easting/ Elevation (Nee) - Projected local coordinates that are used by a design.Orientation - The direction the blade is facing.Pan - To pan is to move around the screen at the same scale. Pan moves the plan sideways or up and down on the screen.Position Dilution Of Precision (Pdop) - A measure of quality of the GPS position. PDOP values below seven are satisfactory. The ideal PDOP value is one. Values from two to four are good.Slope - The forward and aft grade (or mainfall) of the machine.Real-Time Kinematic - The term "real-time" literally means to be performed immediately, not at a later time. The term "kinematic" literally means to move around. Corrections for positions are obtained in "real time" in the
