Downloads and USB drives

If you already have installed Terramodel 10.61K, and your membership is paid up to 1 April 2017 or later, download just the Geocomp Update from 10.61 K to L. See release notes.

If you have installed Terramodel 10.61, but have not installed Terramodel 10.61K, download Geocomp Update 10.61K first. See release notes.

You have not installed Terramodel 10.61, find your Terramodel 10.61 installation CD, DVD or USB drive, download our Complete Terramodel 10.61K+L installation or request the same installation to be supplied on a USB drive. This USB drive is supplied to all who purchase a new Terramodel licence and to Customer Care Members on request. This installation includes Trimble Terramodel 10.60 and the upgrades to 10.61, to Geocomp Update K and from K to L. See release notes.

The commands in the Geocomp Updates are described in the current TML List. Commands marked in red have been updated since the release of Geocomp Update L. If you want the latest version of these commands or to determine the membership dates for your licences, please ask us. Your membership dates and licence numbers are also on the Customer Care Certificate that we post to your company when you renew Membership.


Please read the release notes!

If you have the complete installation on USB, use Windows Explorer to browse to the drive. If you have an .ISO file, use Windows Explorer to right-click then select Mount. If Mount is not on the right-click menu, Open with... Windows Explorer. Alternatively, extract the whole contents of the .ISO to the root of a USB drive, or burn a DVD.

With each of these methods, browse to root of the drive letter (Do not simply extract the contents to a folder; you need a drive with a letter).

Select autorun.exe to open the installation menu. Select Complete Installation then complete the five steps to install Trimble Terramodel 10.60, the upgrade to 10.61, our Geocomp Updates K and L, and the Sentinel dongle drivers.

To add Mount to the right-Click menu, associate .ISO files with Windows Explorer (in Windows 8 and 10), or with a program such as WinCDEmu or Power2Go.

Modules and Membership

Most Terramodel commands require relevant modules on a valid Terramodel security key. Most Geocomp Update commands also require Customer Care Membership from Geocomp Systems.
