Trimble Access 2020.20 was released this week and is available for Windows 10 controllers, on the TCU5 and TDC600 powered by the Android OS. You can view the release notes here.

Subscription Pricing Now Available for Trimble Access

Trimble Access v2020.20 introduces a new way to purchase the software on a subscription basis. The new subscription pricing may be valuable for companies that purchase software on an annual or project basis. Subscription pricing also makes it easier for smaller survey companies to get access to the best field software for surveyors. The standard purchase options are still available. To learn more about subscription pricing, and to see if it's right for your company, a more detailed description can be found here.

Changing the size of the map and form

You can now use a simple slider control to resize any form that appears alongside the map, on any controller. A larger form can be especially useful when using a feature like Measure codes, where you are interested in larger buttons and are not interested in seeing much of the map, or any map at all. On smaller controllers with a 5 and 6" screen it allows you to control how much of the map is visible alongside the stakeout deltas.

In addition, the software now remembers your preferred size for different groups of forms.

  • When viewing the Trimble Access software in landscape mode, tap and swipe left or right to resize the form. In portrait mode, tap and swipe up or down to resize the form. The form resizes to the closest preset position.
  • To minimize the form temporarily to get a larger view of the map, tap and swipe to the very right of the screen, or tap and swipe down to the very bottom of the screen
  • To make any form full-screen, tap and swipe to the very left of the screen, or tap and swipe up to the very top of the screen.

Update projects created in Trimble Access to the cloud

You can now upload projects you have created locally on the controller to the cloud. Simply select the project in the Projects screen and then tap (:) and select Upload. Once the project resides in the cloud you can select and upload any local jobs to the cloud from the Jobs screen.

Projects and jobs that reside in the cloud can be easily shared with other team members or managed from the office using Trimble Sync Manager.

Surface Inspections

Use the new Surface inspection feature to compare an as-built surface, such as a horizontal floor, inclined or vertical wall, or cylinder, with a reference surface. The Surface inspection Cogo function calculates the distance to the reference surface for each point in the selected scan(s) and creates an inspection point cloud.

Points in the inspection point cloud are color-coded to provide immediate visual feedback between the point cloud and the reference surface. When inspecting a horizontal floor, for example, you will be able to see immediately any parts of the floor that are lower than they should be, and any parts of the floor that are higher than they should be.

Select any scan point to view information specific to that point. When connected to a conventional instrument that has a laser pointer, you can turn the instrument to the selected point to identify areas out of tolerance and assist with any remedial work.

Tap Store to save the inspection point cloud to the job. You can also save screen captures and annotate them if required, to highlight particular point details and problem areas.

Repeating SX10 Scans

If you are using a Trimble SX10 scanning total station to scan the same area multiple times, you can now quickly and easily repeat scans by loading a previous scan in the same job or a linked job. For example, you can scan a floor once to find the high or low areas that need leveling, and after performing remedial work you can repeat the scan to confirm the floor is within the required tolerances.

Coordinate system enhancements

RTX positions now transformed using local displacement models

Improvements have been made to the time-dependent coordinate transformation feature, which is used to transform RTX positions between ITRF 2014 at the epoch of measurement and the global reference frame:

  • Local displacement models are used when available.
  • Where no local displacement model is available, Trimble Access uses ITRF tectonic plate velocities, rather than the MORVEL56 tectonic plate models that were used in earlier versions.
  • Country-specific realizations of the ETRS are used in Europe.

These improvements ensure that users obtain optimal accuracy in coordinate transformations and the best possible coordinates in the selected coordinate system.

For a list of affected countries, refer to the latest release notes .

To use Trimble Access 2020.20 jobs that use displacement models in Trimble Business Center, you must use Trimble Business Center version 5.40.

Older Trimble Access jobs with RTX data can be used in Trimble Access 2020.20. When you select the job the software will warn that the coordinates are different. You can choose whether to upgrade the job so that you can use it with the new displacement model. Note that the as-stored RTX coordinates do not change, just the transformation. If you choose not to upgrade the job you will only be able to use the job in a previous version of Trimble Access.

Trimble Access now automatically selects the Tectonic plate used for RTX surveys

When you start an RTX survey, Trimble Access now uses the local displacement model, or if no local model is available for your location, the software selects a tectonic plate in the global tectonic plate model, to propagate the ITRF 2014 coordinate from the epoch of measurement to the Global reference epoch for the job. Previously the software prompted you to select the tectonic plate to use. The Tectonic plate field now appears in the Select coordinate system screen, rather than the Job properties screen. The Tectonic plate field appears only if the Displacement model is a global tectonic plate model (ITRF 2014). TA-40898 Trimble Access now supports keying in an ITRF 2014 coordinate as X, Y, Z, and T coordinates.

Supported controllers

Windows 10 devices:

  • Trimble TSC7 controller
  • Trimble T7 or T10 tablet
  • Supported third-party Windows tablets

Android devices:

  • Trimble TDC600
  • Trimble TCU5

Installation Information

To install Trimble Access 2020.20 onto a supported controller you must have a Trimble Access software maintenance agreement valid up to 1 Dec 2020. To install the software to your controller, use the appropriate Trimble Installation Manager for your controller operating system.

To upgrade from an older controller to a new controller, you can relinquish your Trimble Access software license from an older controller that has current software maintenance using the Trimble Installation Manager. Once your distributor has reassigned the licenses to your new controller, you can install Trimble Access to the new controller using Trimble Installation Manager.

For more information refer to:


Don't have a current license? You can still try out the software on Windows devices.

We have made it easier for you to try out the latest version of Trimble Access. You can use Trimble Installation Manager to create a limited demonstration license and then install Trimble Access 2020.20 onto any Windows 10 computer. Demonstration licenses are limited to adding 30 points per job, however large jobs created elsewhere can be opened and reviewed. Demonstration licenses allow connections to GNSS receivers and total stations for the first 30 days. After 30 days you can only "connect" to the GNSS emulator and manual instruments.

TIP – Demonstration licenses are available only for Windows. To view how the software would look on a TDC600 controller, use the Simulate controller function in Trimble Access and select TDC600. For more information, see the topic To simulate a controller in the Trimble Access Help.
