Grade control systems
How does GPS grading work?
Advanced machine control systems use GPS satellite signals to provide accurate, real-time information about a job site.
This data is then used to create a digital topo, or survey, that records the measurements of the location and maps out changes to elevation or gradient across the site, quickly and efficiently..
How does GPS work on a motor grader?
GPS/GNSS on dozers and motor graders measure the position of the blade's cutting edge by putting a receiver antenna on the blade (although some newer dozer systems have done away with the antenna masts and use small inertial measurement units [IMUs] mounted to the body of the machine.).
How does machine control work?
Machine control systems combine positioning sensors with computer displays to give operators better insight into and control over their work.
Enable operators to accurately position buckets, blades and other implements while eliminating the need for surveying, staking, and constantly checking work in progress..
What is 2D grade control?
Cat Grade with .
- D is an indicate-only system that provides elevation and slope guidance to the operator.
Informs the operator of the distance above, below or on-grade between the bucket cutting edge and the benchmark point.
Works with Grade Assist to add semiautonomous digging capability and single lever digging.
What is cat grade control?
Cat Grade for motor graders is a machine-integrated system to boost grade accuracy, efficiency and productivity on the jobsite.
See the different grading technologies below and learn how to achieve better grades faster..
What is grade control on a dozer?
Automatically control the machine to follow any horizontal alignment from the .
- D model.
This allows the operator to focus on grade, machine productivity and safety rather than worrying about steering, for increased situational awareness, better accuracy and improved productivity with decreased overlap and fewer passes.
What is machine control system?
In civil engineering, machine control is used to accurately position earthwork machinery based on .
- D design models and GPS systems, and thus aid machine operators to e
.g. control the position of a road grader's blade.
What is Trimble grade control?
The Trimble Earthworks Grade Control Platform helps dozer operators cut the confusion that leads to wasted time.
Reengineered from the ground up, our innovative, next generation grade control platform helps make you more efficient and productive..
- Advanced machine control systems use GPS satellite signals to provide accurate, real-time information about a job site.
This data is then used to create a digital topo, or survey, that records the measurements of the location and maps out changes to elevation or gradient across the site, quickly and efficiently. - This technology uses sensors, total stations, GPS systems, and .
- D software to create a digital model of the construction site or mining area, and to provide real-time information about the location, orientation, and movement of the equipment
A grade control system ensures soil is stripped at exact measurements based on the topo integrated into the system, allowing contractors to save on labor costs.
Grade-control systems use a combination of GNSS, inertial and laser or total station technology to accurately position the excavator's bucket or dozer blade in real time. Using an in-cab display, the operator then sees the 2-D or 3-D design surface, grade or alignment inside the cab.
What are the benefits of cat grade control systems?
Whether a 2D grade and 3D grade system, self-contained or using laser or GPS guidance, Cat grade control systems improve grading efficiency

What grade control systems are available?
There are many grade control systems available in the market today: Entry-level 2-D systems —The 2-D grade control system allows operators to set up a laser transmitter to cut to their desired grade, on both flat and sloping surfaces
What is a Trimble grade control system?
A Trimble grade control system is an excellent first investment for contractors new to construction technology
Use one or two laser receivers to achieve fully automatic control of the blade using a laser reference Use a cross-slope only system to automatically control the blade slope, while the operator controls blade elevation
Grade control or machine control systems mean an earthmoving machine is being partially controlled by technology and not the operator. On an excavator, it means technology helps control the boom and bucket functions of a machine via set parameters from the operator while digging with a bucket.,There are many grade control systems available in the market today: 1. Entry-level 2-D systems—The 2-D grade control system …
Concussion grading systems are sets of criteria used in sports medicine to determine the severity, or grade, of a concussion, the mildest form of traumatic brain injury.
At least 16 such systems exist, and there is little agreement among professionals about which is the best to use.
Several of the systems use loss of consciousness and amnesia as the primary determinants of the severity of the concussion.
Pan-European school grading system
The ECTS grading scale is a grading system defined in the European Credit Transfer and Accumulation System (ECTS) framework by the European Commission.
Since many grading systems co-exist in Europe and, considering that interpretation of grades varies considerably from one country to another, if not from one institution to another, the ECTS grading scale has been developed to provide a common measure and facilitate the transfer of students and their grades between European higher education institutions, by allowing national and local grading systems to be interchangeable.
Grades are reported on a carefully calibrated and uniform A-to-F scale combined with keywords and short qualitative definitions.
Each institution makes its own decision on how to apply the ECTS grading scale to its system.
