INSTRUMENT 0333110 - Caterpillar

Pan - With "Auto Pan" on, when the machine nearly reaches the edge of the screen, the following occurs: the map is moved and redrawn so the machine is near the opposite edge of the screen and heading toward the center.Case station - A base station must be set up with the Cat Grade Control system which includes a GNSS receiver and data radio. This station transmits CMR messages to the machine to improve position accuracy.Compact Measurement Record (CMR) - A CMR is 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.Dialog - Screen that requires entering of text or numbers, or selecting optionsDifferential Global Positioning System (DGPS) - Technique that uses GNSS satellite technology and radio telemetry to calculate a position to better than 1 m accuracyDigital Terrain Model (DTM) - Electronic representation of the design in three dimensions. TINs and grids are two types of DTMsFirmware - Firmware is software that is stored in read-only memory (ROM) or programmable ROM (PROM). Firmware runs the Cat Grade Control system.Global Positioning System (GPS) - Technique that uses satellite technology to calculate an accurate three-dimensional positionGridded 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 movingLight Emitting Diode (LED) - A small, bright, and generally a colored light that is used in electronic componentsLoad - Load means to put data onto a USB flash drive device so that the USB flash drive device can be used. Load also means to copy data into the display from the USB flash drive device.Northing/easting/ elevation (NEE) - Projected local coordinates that are used by a designOrientation - Direction the cutting edge 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) - PDOP is a measure of quality of the GPS or the GNSS position PDOP values below seven are satisfactory. The ideal PDOP value is one. Values from two to four are good.Pitch - Forward and aft grade (or mainfall) of the machineReal-time kinematic (RTK) - 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 GPS or the GNSS receiver.Reference station - Refer to base station.Rover - The rover is the GNSS receiver on the machine. A single reference or base station can support an unlimited number of rovers.Side slope - Side slope is the average grade or slope of ground expressed as a percentage. Generally side slope is used to describe a cut or fill slope from the edge of a road to the natural ground surface. A vertical surface has a side slope of zero.Soft keys - A soft
