Trimble GNSS (COM26) Driver

The Trimble GNSS (COM26) driver enables Windows to communicate with a compatible Trimble GNSS receiver over USB through a virtual serial port. It is intended for surveyors, mapping professionals, and other users who need their positioning software to recognize the receiver and access its data. The COM26 label identifies the assigned communication port, not necessarily the receiver’s model.

Key Features

• USB communication support: Provides the connection needed for compatible Trimble hardware to communicate with Windows applications.
• Virtual COM port access: Allows software that uses serial connections to access the receiver through its assigned port.
• GNSS software connectivity: Helps compatible surveying and mapping applications exchange data with the connected receiver.
• Legacy Windows options: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP; check the individual package for exact compatibility.

How to Install Trimble GNSS (COM26) Driver

1. Identify your receiver and Windows version. Check the receiver’s model and whether your system uses 32-bit or 64-bit Windows. For Windows 10/11 systems, note that Windows 10 is listed as supported, while Windows 11 compatibility must be confirmed separately.
2. Choose a compatible package. Before starting your Trimble GNSS (COM26) driver download for Windows, verify that the package matches your hardware and operating system. Select the latest version that explicitly supports your setup, and use a trusted source when choosing a free download.
3. Prepare the installation. Close applications using the receiver. Extract the downloaded archive if needed, then follow the package instructions about when to connect or disconnect the USB cable.
4. Install the driver. Run the supplied installer, if included. For a manual installation, open Device Manager, locate the receiver or unrecognized USB device, select Update driver, and browse to the extracted driver folder.
5. Verify the connection. Reconnect the receiver and restart Windows if prompted. Check Device Manager for the assigned COM port, then select that same port in your GNSS application. The port number may differ from COM26 on another computer.

Keep the driver updated when Trimble provides a compatible release that addresses connection issues or supports your workflow. Before an update, review compatibility notes and retain a working installer so you can restore your previous setup if necessary.
