In addition to the display, there are a number of sensors that are used with the system. The display and sensors are connected by a system harness that allows the components to send data and commands between each other.
Additionally, the Cat Compaction Control for Landfill Compactors requires one of the following types of base stations somewhere near the project:
- Global Positioning System (GPS)
- Global Navigation Satellite System (GNSS)
The control box is a computer that runs the system software and provides control of the guidance system. Guidance information is provided by control box via the following system components:
- The control box and lightbars
- The remote switches, if installed
- The audible alarm, or beeper

The control box has a color LCD screen to display guidance and other information, and push-button controls to operate the system. In addition, the control box has internal lightbars, and a USB flash drive port for loading and saving machine and display configuration data, and for loading and saving data.

Rugged Zephyr Antenna ( 386-7311 Antenna) | |
The Cat Compaction Control System uses a GNSS receiver and separate antenna (shown in Illustration 2) to determine the location of the machine in three-dimensional space.
The receiver can calculate drum location by using information that is broadcast from GPS and GLONASS satellites. The receiver will also use information broadcast from the GNSS satellites if a GNSS base station is used.

A data radio is used to receive data from one of the following types of base stations:
- GPS
- GNSS
The data radio (shown in Illustration 3) is required to be working before the system can be used. The GPS data radio can also be used to send and receive files and other types of data from the office.
Currently, Caterpillar does not support radios. A radio from Trimble is recommended.
When using an RTK mapping system, one of the following types of base station is required for the Cat Compaction Control System to function correctly:
- GPS
- GNSS
Currently, Caterpillar does not support GPS base stations. A base station from Trimble is recommended.
A base station consists of the following components:
- GPS Receiver or GNSS Receiver
- GPS Antenna or GNSS Antenna
- Radio
- Cables
- Power Supply
There may also be a tripod or a mast for the antenna and the radio. For construction sites when work can continue for a long time, use a semi-permanent location such as the roof of the site office. A reliable power supply is needed.
Make sure that the base antenna is clear of obstructions, reflected signals, and sources of electromagnetic interference such as power lines. The data radio for the base station must be elevated several meters off the ground to provide optimum coverage.
The base station requires a starting location. For best results set up the receiver for the base station on a surveyed point. To establish this survey point, use a site calibration or a professional surveyor experienced with this type of equipment.
Correctly set the antenna type at your base station. The position is degraded if the incorrect type of antenna is selected.
