How is the position of the trailer determined during the soil uni-directional installation of the MASS?

The correct choice is based on the method used to determine the position of the trailer during the soil uni-directional installation of the MASS (Mobile Automated Soil Sampling). The installation process requires precise calculations for the positioning of equipment to ensure effective sampling without compromising the functionality of the system.

In this case, the addition of 15 to the cable length is a specific calculation that helps account for various factors, such as the necessary slack in the cable and any additional length required to ensure that the trailer is at a safe and effective distance from the point of installation. This distance ensures that the equipment can operate correctly and that the sampling process is not hindered by any physical obstructions.

Understanding the importance of the cable length and its impact on the positioning underscores the technical precision required in the operation. Each adjustment or addition in measurements is based on operational protocols that ensure efficiency and accuracy during the installation process. This choice reflects the necessary considerations for a successful setup in soil sampling operations.
