As the construction world moves toward smarter, more automated work, FJDynamics has recently launched the TPS version of the H36 PRO 3D motor grader control system. This new system takes all the great features of the original H36 PRO and adds an extra layer of precision. By using total station positioning, it helps graders to grade with millimeter-level accuracy. This makes it a perfect solution for the most challenging construction sites, helping crews get the job done right the first time.
What Is TPS?
TPS stands for Total Positioning System. It has been used for a long time in surveying and construction. At its core, TPS is a highly precise tool to measure angles and distances. However, integrating this technology into a construction machine like a grader brings challenges in algorithm stability, tracking speed, and environmental adaptability. The H36 PRO TPS version represents a major leap forward in all these dimensions.Think of it this way: Standard GPS or GNSS uses satellite signals to figure out a machine's location. This works great in open fields, but on a busy construction site with tall buildings or other obstacles, those signals can be blocked. TPS, on the other hand, relies on a direct, line-of-sight measurement between the grader and a total station on the ground. Because it doesn't depend on a clear view of the sky, it's the ideal choice for complex environments where you need the highest accuracy.
How Does TPS Work?
Here's a simple breakdown of how the H36 PRO TPS system works: a small prism is attached to the grader, and a total station is set up on the ground nearby. This total station constantly watches the prism as the grader moves. It tracks the prism's exact position in real time—down to the millimeter—and sends that precise location data directly to the H36 PRO control terminal inside the grader's cab. The system then takes this live position data and compares it to the digital design plan for the job site.If the system detects a difference between where the grader is and where it's supposed to be, it automatically corrects the course. Then, the control terminal instantly adjusts the blade's height and angle, making sure the grader stays perfectly on target. This constant automatic control ensures that the grading is flawless, with no uneven spots or wasted material, which saves a huge amount of time and effort on the job site.
The Application Cases of TPS and Its Advantages
TPS is especially useful in construction scenarios where GNSS signals are weak or unreliable, such as dense urban centers, underpasses, tunnels, high-rise clusters, and forested areas. In these places, traditional satellite-based systems often fail to maintain accuracy due to obstructions. But TPS doesn't have this problem. It uses optical tracking to deliver consistent and highly accurate positioning no matter how many obstructions are around.The key features of the TPS mode make it a powerful tool. It constantly captures the grader's coordinates, precisely tracks the prism, compares its real-time position to the digital design plan, and automatically controls the blade. All of this happens without the operator needing to do any manual adjustments.
TPS brings several key advantages:
- Millimeter-level accuracy, which is more precise than standard GPS systems.
- Required no satellite signals, it works flawlessly in places with obstructions.
- Stable and fast, even when the grader is moving quickly or working in tight spaces.
- Flexible integration with GPS systems let you choose the best setup for any job site.
Real-World Testing: Validated Across Asia with Outstanding Results
The H36 PRO TPS system has been thoroughly tested on job sites across Asia, and the results have been a huge success. During these tests, the total station was able to track the grader's prism with perfect precision, even as the machine moved and changed direction. Meanwhile, the blade—controlled by the system—dynamically adjusts itself according to the terrain and the design model, resulting in a smooth and highly controlled grading process.Test teams have praised the system for its quick deployment, rapid tracking, and reliable operation. Most notably, field measurements confirmed millimeter-level grading accuracy, fully proving the system’s engineering practicality and effectiveness.
Coming Soon: TPS Radio Communication Kit
To make setting up the TPS system even easier on different job sites, FJD will soon launch a new TPS radio communication kit. This kit will include a high-performance survey-grade radio, quick-mount brackets, and a built-in power module. This ensures fast and stable data transmission over long distances or in areas with a lot of signal interference.This new kit gives you the flexibility to use the TPS solution with your existing GPS system. You can easily add the high-precision TPS system whenever you need millimeter-level accuracy, and then switch back to your standard GPS system for other tasks. This way, you can always choose the perfect tool for each stage of your project and for any environment.
