In this video, we will show you how to set GPS control points for the Trimble SPS930. Control points are known locations on the ground that are used to reference the position of other points. They are essential for ensuring the accuracy of surveying and construction projects.
To set a GPS control point, you will need:
* A Trimble SPS930
* A GNSS antenna
* A tripod
* A level
* A measuring tape
Once you have your equipment, follow these steps:
1. Set up the tripod and level it.
2. Attach the GNSS antenna to the tripod.
3. Power on the SPS930 and select the "Set Control Point" option.
4. Enter the coordinates of the control point.
5. Press the "Set" button.
6. The SPS930 will now survey the area around the control point and calculate its position.
7. Once the calculation is complete, the SPS930 will display the coordinates of the control point.
You can now use the control point to reference the position of other points.
Here are some additional tips for setting GPS control points:
* Choose a location for the control point that is clear of obstructions and has a good view of the sky.
* Make sure the tripod is stable and level.
* Enter the coordinates of the control point carefully.
* Repeat the survey if you are not confident in the results.
Setting GPS control points is an essential part of surveying and construction projects. By following these steps, you can ensure that your projects are accurate and reliable.
