Trimble Releases A New Version Of GNSS Firmware


New release and installation instruction

Trimble recently released a new version of GNSS Firmware. Our support and service staff have ran it through their tests, and they’ve given the all clear to install. Below are the receivers that are supported with the new release. You need to have a warranty expiration date of June 2017 or later. If you’re unsure of your warranty date, please email Daisy.

Note: For best results, users should upgrade to Trimble Access 2017.10 or later when using Survey GNSS Receiver Firmware version 5.32.

Before you update the receiver, download and backup any data files that are on the receiver.

There are 2 ways to install – one is with the TRIMBLE INSTALLATION MANAGER, another is with WINFLASH. Please read below to determine which choice you need to use. Contact our support staff (contact info at bottom of this post) if you have any questions.

Trimble Installation Manager is a free download and can be found here:

The following GNSS receivers are currently supported:

  • Trimble R2 (Firmware Installation)
  • Trimble R8s (Warranty Activation, Option Loading, Radio configuration, Firmware Installation)
  • Trimble R9s (Warranty Activation, Option Loading, Radio configuration, Firmware Installation)
  • Trimble R10 (Firmware Installation)
