Decoding Modern Construction: Machine Control Systems Explained

Positioning Fundamentals: Beginning in the Atmosphere

Precision in machine control starts high above the site in the atmosphere with GPS satellite constellations. These satellites determine their positions through triangulation, offering location accuracy down to the centimeter. Software engineers then create a digital model of the construction site. By using the precise positions of assets and machines, they sync the machinery on the actual construction site with this digital plan, ensuring the desired outcomes of the job are achieved on the ground.

Base Stations: Crucial Players on the Ground

Base stations are essential components on the construction site. They capture GPS signals and then broadcast correctional data across the job site. Whether through their built-in radios or using powerful external radios like the Satel EASy Pro+ 35W, they guarantee centimeter-level accuracy throughout the site. This level of precision is indispensable in today’s era of smart construction.

The Role of Rovers in Advanced Construction:

Rovers, equipped with advanced receivers like the internal MR-TR4+, tap into the signals and receive the correction data. The onboard computers map their location in the onboard display which shows a 3D map of the site, pinpointing their exact location on the site and guiding their actions accordingly giving the operators a competitive advantage over traditional machines

Alternative Systems:

Cellular Systems/NTRIP: These are a modern twist, leveraging cellular signals and connecting to offsite reference stations, eliminating the need for onsite base stations.

IMUs (Inertial Measurement Units): These are the unsung heroes in the background, rapidly calculating position changes and working in tandem with other systems to ensure precision in the relative location of the machine in the digital blueprint.

The Building Blocks: Components of a Machine Control System

Troubleshooting SATEL Radios

The most frequent cause of Satel Radio issues is a mismatch in settings between the transmitting radio and the receiving radio. The key settings that must be the same on both radios are:

  • Frequency
  • Channel Spacing
  • Radio Compatibility/Protocol
  • Error Correction (FEC)

Note: On other Satel-compatible radios, or via 3rd party interfaces (such as Leica or Carlson Software), these terms may have different names. Other settings, such as Error Checking are uncommonly used.

Troubleshooting Steps

Base Radio

  1. Start with the base/transmitting radio. The “TD” light should be blinking. If it isn’t, that means the transmitting radio is not receiving data via its serial port. Check the settings on the attached device to ensure it is correctly sending data via the serial link.
  2. Note down the 4 above settings using the radio screen and buttons. The settings are found in the following menus:
    1. Frequency: “Radio frequency” menu (“TX & RX freq”)
    2. Channel Spacing: “Radio frequency” menu (“Ch Spacing”)
    3. Radio Compatibility: “Radio settings” menu (“Compatibility”)
    4. Error Correction/FEC: “Additional” menu (“Error corr.”)

Remote Radios

  1. Start by checking received signal strength. In the upper right corner, the number shown with a negative sign is the RSSI. A normal RSSI should be between -40 and -100 or so, with a higher number closer to the transmitting radio, and a lower number farther away. During normal operation the RSSI will likely change between a higher number, such as -60 and a low number (typically -120 or below).
    1. If the number stays low (below -100), the radio is not receiving a signal over the air, which indicates the frequency on the base radio and remote radio is not matching, or the base radio is not transmitting. Check and program the frequency on both radios.
  2. If the signal strength is high (above -100), or changing between a high and low signal, the next step is to check the RD light, which should be blinking. If it isn’t, this indicates a settings mismatch (the radio hears a signal, but can’t decode it). Check and program the 3 other settings (Channel Spacing, Radio Compatibility, Error Correction/FEC).
  3. If the RD light is blinking, but your data still isn’t making it through, check the Baud Rate on the receiving radio (in the “Port 1” menu), and ensure it matches the settings on the device attached to the receiving radio.

Further Troubleshooting

The above steps cover the most common issues seen when setting up a Satel radio system. If the instructions don’t address your situation, or you are unsure how to match settings on a Satel-compatible device, such as a radio from another manufacturer, or via 3rd party configuration software, please contact us.
