Modern surveyors have to juggle accuracy, time, and manpower more than ever before. The rise of solo surveyors and integration with BIM systems makes robotic total stations essential for modern workflows. You’ve probably heard the buzz about these total stations, but few brands carry the weight that Trimble does in the field.
Precision has a name—Trimble. A Trimble robotic total station can streamline nearly every aspect of the surveying process, from LiDAR integration to cloud data synchronization and automated monitoring. Think of the feeling of confidence you’ll have when your total station locks onto the prism perfectly every time.
Let’s look at the Trimble total stations available today. We will explore five models that give the best results. We’ll also explore how robotic models work and how to use them effectively. Explore more high-precision gear at Harper Surveying’s Total Station Collection.
What Is a Trimble Total Station?
Consider a total station like the surveyor’s eyes and brain rolled into a single package. Manual stations still give many measurements and high precision. However, they need more input from the surveyor.
Semi-robotic and robotic total stations are special tools. They provide automatic rotation and motorized adjustments. They also feature advanced electronic distance measurement (EDM) capabilities, including prism tracking.
Total stations measure angles, distances, and coordinates. They utilize both optical and electronic precision, regardless of the level of technology.
We have come a long way from classic theodolites. These tools only measured angles. Surveyors used tapes and other tools that were less accurate than EDM.
That’s where Trimble comes in. Trimble is a leader in accuracy and automation. Each Trimble robotic total station for surveying has many features. These features and connectivity options help improve efficiency while working.
Trimble built its reputation by creating software solutions like Trimble Access, ensuring durability for real-world challenges, and prioritizing field efficiency. Their robotic total stations enable one person to work independently without compromising accuracy. In contrast, manual total stations need at least two team members to operate.
These total stations are essential for creating accurate construction layouts, topographic mapping for various large-scale public projects, and monitoring and repairing infrastructure. When you have only one chance to set the grade before the concrete trucks arrive, accuracy is essential. That’s why surveyors across the industry trust the Trimble robotic total station.
How Does a Trimble Total Station Work?
So, how does a robotic total station work in a step-by-step process?
- This advanced surveying tool automatically follows a prism. It uses sensors and servo motors to adjust its aim.
- Each Trimble robotic total station connects wirelessly to a field controller. This helps collect important data. It often uses a strong radio or Bluetooth connection. This connection works well, even far from a Wi-Fi signal.
- The operator controls the measurement process and logs data remotely, thereby improving efficiency and enabling solo operation without compromising accuracy.
A robotic total station is like having a robotic camera that never loses its focus—even when you move. Trimble’s advanced tracking technology includes MagDrive™ servos. These servos provide silent and smooth motion control, resulting in reliable measurements.
You will hear the smooth sound of servo motors turning on. They activate the Autolock™ target recognition system. The SurePoint™ feature helps adjust for any unexpected movement or vibration.
You can use Trimble controllers (TSC5 and TSC7 models) and Trimble Access software for wireless connections. This lets you operate the station remotely when needed.
Ultimately, these robotic total stations enable a single person to operate them. They expedite the setup process and significantly reduce errors and corrections. Once you see how well a Trimble robotic system works, you will find it hard to return to traditional two-person setups.
How to Use a Trimble Total Station (Field Basics)
This Trimble total station tutorial covers the basic steps for field work. It demonstrates how upgrading to robotic equipment can simplify your operations.
Set up the Tripod
Total stations work on control points, and you need to set the equipment over a known coordinate. You set up the reflector rod at another known point, creating a reference for the rest of the measurements you’ll take.
Find a firm, stable section of ground to place the tripod. Raise the tripod to approximately chest height, tighten the extension pegs, and spread the legs to form even angles. Place the feet or spikes into the ground so that they sink into the surface, then attach the Trimble robotic total station.
Level and Center
Align the base of the total station with the tripod top, then use any bolts or pegs to secure it in place. Keep a hand on the side or top of the station while fastening it in place.
Use the built-in spirit level to adjust the height of each tripod leg. Make sure the station is level and centered. Align the instrument precisely over the known point, moving the entire tripod as necessary.
Initialize the Instrument
It’s time to power up the total station! Make sure you’ve charged the batteries—you don’t want any simple issues holding you back once you’re in the field.
Consider calibrating the total station before its first use and after any major shocks, bumps, or extended storage periods. Calibration requires approximately 300 feet of clear line of sight over relatively flat terrain. You can choose from three types of calibration: compensator, collimation/trunnion axis tilt, and autolock collimation.
The instrument will do the hard work for you. Select a fixed target approximately 300 feet away for the second calibration and measure vertical angles around that distance for the third process.
Once you’re calibrated, aim at the prism while it’s in a fixed position. Test the AutoLock feature by performing a few simple movements at a distance of around 100 to 300 feet.
Connect a Controller
Turn on your field computer, tablet, or TSC7/TSC5 controller. If you are using Trimble Access, open it. Verify that all your settings and corrections align with the work you plan to do.
Measure and Record
Now you’re ready to start observing angles and distances without needing a partner to operate the total station. You can adjust the position of the prism and rod as is necessary to activate and control the station remotely. Don’t forget to direct where you want the data stored, whether that’s on the device’s built-in storage or in a secondary device connected via radio or Bluetooth.
Troubleshooting
Signal Loss: Restart the total station and controller, and verify that all cables are intact and connected. Replace the battery for a power boost. Verify the radio details, like the frequency and protocol, as well.
Prism Alignment Issues: Check the prism constant for your reflector and ensure that the measurements are set to the correct amount of correction. Make sure you use a prism that is approved for your Trimble model. Some prisms may not work with foil or acrylic reflectors.
Calibration Drift: Avoid dropping or bumping the total station, and try to limit extreme temperature changes. Re-calibrate if the error rate is too high or measurements remain out of alignment after the initial calibration.
Data Transfer
Gathering data in the field is a good start, but you’ll need to sync to Trimble Business Center or other CAD software to complete your work. The data transfer process is smooth, regardless of the method used, from onboard removable storage options to digital transfers.
