These Release Notes describe the new features and changes available in this release of the Trimble® Access™ software.

New features

IMU tilt compensation

Trimble Access version 2020.10 supports IMU tilt compensation when using the new Trimble R12i receiver with Trimble Inertial Platform™ (TIP™) technology.

Inertial Measurement Unit (IMU) tilt compensation allows points to be measured or staked out while the survey pole is tilted or tipped. The pole can be tilted at any angle and the software is able to calculate the tilt angle and the tilt distance to determine the position of the pole tip on the ground.

When enabled, IMU tilt compensation is "always on" and can be used for any measurement method except observed control point. When measuring an observed control point, the receiver automatically switches to GNSS-only mode.

IMU tilt compensation offers a completely different way of working because you can:

  • Measure accurate points quickly while standing or walking without having to level the pole.
  • Concentrate on where the pole tip needs to go, which is especially useful during stakeout.
  • Easily survey hard-to-reach locations such as building corners and pipe inverts.
  • No longer worry about movement of the pole when measuring, because the receiver automatically corrects for “pole wobble” when the pole tip is stationary.

Because performance is unaffected by magnetic interference, IMU tilt compensation can be used in environments susceptible to magnetic disturbance such as around vehicles, heavy machinery, or steel reinforced buildings.

IMU tilt compensation is also now supported when using a Trimble SPS986 GNSS Smart Antenna with firmware version 6.08 or later installed and the IMU or Premium Precise Rover option code installed on the receiver.

For more information, see the topic IMU tilt compensation in the Trimble Access Help.

Support for TDC600 internal compass

Trimble Access now supports the compass in the TDC600 controller. You can use the compass when staking out a position or navigating to a point. To use the compass, from the Stakeout screen or the Navigate to point screen, tap Options and select the Compass check box. Trimble recommends you disable the compass when you are near magnetic fields that may cause interference.

If you are using IMU tilt compensation and the IMU is aligned, the heading from the receiver is always used to orient the GNSS cursor, the large stakeout navigation arrow and the close up screen. You must be facing the LED panel of the receiver for these to be orientated correctly.


Trimble Access apps on Android

In addition to Trimble Access Roads, the Pipelines, Tunnels, Mines and Monitoring apps are now supported when running Trimble Access on a supported Android™ device.

For more information, see Trimble Access App availability.

Auto-switching to appropriate Favorites group

If you use both GNSS and conventional survey equipment, it's a great idea to create a group of Favorites shortcuts and functions that apply to a conventional survey, and a different group of Favorites appropriate for a GNSS survey. Now, Trimble Access can automatically switch to the appropriate Favorites group when you start the survey.

To enable auto-switching, create the groups in the Favorites screen. Tap next to the group name and select the required Auto-switch option to have the software automatically switch to that Favorites group when you start a conventional or GNSS survey. The Auto-switch function works best when you have set up a conventional group and a GNSS group of Favorites. The software will also auto-switch groups when the active instrument changes during an integrated survey.

For more information, see the topic Favorite screens and functions in the Trimble Access Help.

TDC600 function key support

You can now assign your favorite software screens or functions to function keys on the TDC600 controller. The TDC600 provides 4 function keys: FN, left dash, right dash, and the sidekey. Each key can be assigned two short cuts or functions: one for a short key press and one for a long key press.

Creating multiple points with Snap‑to tools

You can now use a Snap‑to tool to create multiple points without reselecting the same tool each time. To use the same tool multiple times, tap and hold the appropriate tool in the Snap‑to toolbar to keep the tool selection active and then select the features in the map. For example, to select the end points of multiple lines, tap and hold the Snap to end button and then select each line. To change to a different tool, tap a different button in the Snap‑to toolbar.

Native TrimBIM (.trb) BIM model support

TrimBIM (*.trb) files are now supported by Trimble Access in the same way as an IFC file. TrimBIM is a BIM model file format invented and implemented by Trimble, and is a smaller, more efficient alternative to IFC files. IFC file settings in Trimble Access apply equally to TrimBIM files.

Managing point files and map files from the Linked files screen

You can now manage map files as well as point files in a single screen, rather than having to go to two different screens. The improved Linked files screen in Trimble Access version 2020.10 groups files into tabs for faster viewing. Use the Point files tab to link to CSV, TXT and job files. Use the Map files tab to link to map data files, including IFC, RXL, image, and surface files, and to show or hide features from map data files in the map. You can connect to a web map server from the Map files tab.

To view the Linked files screen, tap the Linked files button on the map toolbar, or tap Linked files in the Job properties screen.

For more information, see the topic Linked files in the Trimble Access Help.

Map icon updates

The following map icons have been updated to improve cursor visibility and usability:

  • The current position of the prism or GNSS antenna.
  • The current position and heading when using an R12i receiver.
  • The current point being staked.
  • New orbit icon.

Display DXF text

The Map data controls group in the Map Settings screen now includes a Display DXF text check box which allows you to control the display of text entities in a DXF file. Disabling text entity display in a DXF file that includes a lot of text entities can improve map performance.

Viewing exported files on Android

When exporting files from Trimble Access on an Android device, if you select the View created file check box the exported file can now be viewed in Trimble Access.

Export polylines with arcs to DXF

When exporting to DXF, polylines that contain arcs (not just lines) are now included.

Tap and hold options for copying and pasting text

When copying text from one field to another in Trimble Access, you can now cut, copy, or paste text using the Text tap and hold menu:

  • To select text, tap and hold on the word to select, or tap and drag across the field to select more text. The Text menu appears just above the highlighted text.
  • To select all of the text in the field, tap and hold on a word and then tap Select All in the Text menu.
  • To cut or copy the selected text, tap Cut or Copy. in the Text menu.
  • To paste text into an empty field, or to paste at the end of a field, tap and hold in the field and tap Paste.

    To paste text within existing text in the field, tap the insertion point in the text and tap Paste.

On Windows controllers you can also use Ctrl key combination shortcuts to select all Ctrl + A, cut Ctrl + X, copy Ctrl + C, and paste Ctrl + V text.

Auto-populated Prism to antenna offset values

When defining an integrated survey style, the software now auto-populates the value in the Prism to antenna offset field when you tap next to the field and select the prism type. This saves you having to remember or look up the offset values for different prisms.

xFill enabled by default in RTK survey style

For GNSS receivers that support xFill, xFill is now enabled by default when you create a new RTK survey.

Sound events now available in Czech

When Czech is selected in the Select language screen of the Trimble Access software, voice messages such as Observation stored are now provided in Czech instead of English. To be able to select Czech as the language, you must install the Czech language and help files using Trimble Installation Manager.

Coordinate system database updates

  • Updated the RD 2018 coordinate system definition for the Netherlands (supporting the official RDNAPTRANS 2018 transformation).
  • Added a new RD 2018 North Sea coordinate system definition for the Netherlands.

New hardware support

Trimble R12i receiver

Trimble Access version 2020.10 supports the new Trimble R12i GNSS receiver. The receiver has Trimble Inertial Platform (TIP) technology which enables points to be measured using IMU tilt compensation. The receiver also has Trimble ProPoint™ GNSS technology and can be used in GNSS-only mode in situations where IMU tilt compensation cannot be used, such as in difficult RTK environments or when measuring an observed control point.

Trimble 360° prism

Trimble Access version 2020.10 supports the new Trimble 360° prism. The prism supports all GNSS receivers for integrated surveying.

Resolved issues

  • Uploading projects: The cloud icon in the Projects screen now refreshes more quickly after uploading changes in the project to the cloud.
  • Downloading projects: If you cancel the download while downloading a project, the project folder is now removed from the controller.
  • Subfolders in Jobs list: We have fixed an issue where the Jobs screen did not always show the correct subfolder location of recently downloaded jobs, even though the job was in the correct subfolder.
  • Export to DXF: When exporting to DXF from a job that is not the current open job:
    • The data exported to the DXF file is now from the selected job, not the open job.
    • If the Include feature coded linework check box is selected and the selected job is not the currently open job, the software now warns the Job must be open to export feature coded linework and the file is not exported.
  • XML files with USC-2 encoding: XML files such as LandXML or RXL roads that use UCS-2 character encoding can now be displayed in the map and staked.
  • Deleted XSL files on Android: The software no longer restores deleted XSL stylesheets when you restart the software.
  • Map issues: We have fixed these issues in the map, including:
    • The background image was sometimes drawn at the incorrect ground plane elevation if you had previously opened a job with the ground plane set to a different elevation.
    • White text in DXF files was not visible in the map. White text is now automatically drawn in black.
    • The elevation label for a point was not updated if you edited the antenna height for the point more than once.
  • IFC file properties: Properties within a property set in an IFC file are now shown in the order set in the IFC file, instead of alphabetically.
  • Calculate volume: Surface names are now listed only once in the list of available surfaces.
  • Staking a polyline: We have fixed these issues when staking a polyline:
    • Setting the As-staked code to Design code now works.
    • Polyline as-staked deltas information was not appearing in stakeout reports or in Trimble Business Center.
    • The Relative to polyline values, along with the dashed line from your current position to the polyline, are now optimized to provide the best guidance to the target.
    • When staking a PC, PT or PI station, the stakeout navigation screen now shows the polyline either side of the target. Previously it only displayed the part of the polyline that was adjacent to your current position.
    • The Confirm staked deltas screen no longer occasionally shows an azimuth value in the Δ H. Offset field.
  • Measure to surface: We have improved the computation of the Distance to surface value. In certain extreme situations a negative value was computed when it should have been positive, or a positive value was computed when it should have been negative.
  • Cursor behavior in Code field: We have fixed issues when entering text in the Code field, where the cursor position would sometimes skip forwards over existing characters, causing text to be inserted at the wrong location. When pressing the Backspace key, the cursor would sometimes skip backwards, leaving behind characters that should have been deleted.

  • Measure codes buttons disappearing: We have fixed an issue where, if your feature code library did not contain any groups, then any measure code buttons you had configured were removed when you restarted the Trimble Access software.
  • Favorite function keys: We have fixed these issues when using function keys you have assigned to your favorite functions:
    • The software no longer changes to the General Survey app from another Trimble Access app when you press a Function key you have configured to open the Trimble Access Help, Job properties, Import, Export, Copy jobs, Camera, GNSS emulator, or File Explorer.
    • The Measure codes String - and Measure codes String + functions now behave as expected. Previously these functions were reversed.
  • Multiple photo attributes: We have fixed an issue where if a feature code had more than one photo attribute, the software replaced the photo name in the first attribute field instead of populating the second photo name in the second photo attribute field.
  • T02 files on a TDC600: We have fixed an issue when performing an RTK & infill, RTK & logging, FastStatic or PP kinematic survey, and logging to the controller on a TDC600, where the resulting T02 file was corrupted, and could not be read by the Trimble Business Center software.
  • Unexpected satellite tracking changes: We have fixed an issue where viewing any Options form or a survey style screen when connected to a GNSS receiver but not currently running a GNSS survey would change satellite tracking settings in the connected GNSS receiver. Tracking entire satellite constellations may have become enabled or disabled when accepting the Options form with or without making changes.
  • RTK & Infill base information: When an RTK & Infill survey is started and there is no data from the base, you can start the survey in Infill mode. When the base data is received, and you switch back to RTK, the new base detection system now operates correctly and writes the newly detected base coordinates to the job.
  • Broadcast RTCM: We have fixed an issue where sometimes residual grid values could not be appended to the transformation file if the system was busy.
  • APN settings: The Username and Password fields are now automatically filled out when you select the Access Point Name from the APN field in the Create new network connection screen.
  • NTRIP settings: When connecting to an NTRIP server during a GNSS RTK survey, NTRIP user authentication information is now sent correctly when not routing internet RTK data through the controller.
  • Changing conventional measurement methods with keyboard: We have fixed an issue where the software would sometimes move the cursor to the Code field when in TRK mode and you attempted to change the conventional measurement method using the left arrow key.
  • Railroad and chainage distance terminology: If you select these check boxes in the Language screen, the software now displays the appropriate railroad and chainage terminology correctly throughout the software.
  • Event and alert sounds: The software now sounds the event sound and the alert sound when the selected language is not English. These sounds were not included in language packs in Trimble Access version 2020.00.
  • Job name length for languages that use non-Latin alphabets: We have fixed an issue where job names longer than 16 characters were not supported if the selected Trimble Access language uses a non-Latin alphabet, such as Russian or Chinese. All languages now support job names up to 32 characters in length.
  • Application errors: We have fixed several issues that sometimes caused application errors when using or closing the software. In particular:
    • When opening the Jobs screen after using File Explorer to copy a job into a project folder.
    • When downloading a project or job that includes an RTCM datum file that was created in the field.
    • After downloading a job from the cloud while a different job is open.
    • Performing a long key press on any key on the TSC7 keypad.
    • Attempting to view the map when the map contained transparent objects, such as a transparent BIM layer.
    • Orbiting the map when the map includes a TIFF file.
    • Switching to the video view when the map includes polylines that contain arcs.
    • When measuring or canceling a check shot.
    • Computing a new cogo point from an RTX point.

    • Computing a new cogo point using the Distance-Distance intersection or Bearing-Distance intersection method.
    • When the software is running in Czech and you change to the video view when using a Trimble total station.
