About this app

Trimble Mobile Manager is a simple app for configuring and controlling the Trimble Catalyst software-defined positioning service, which can deliver meter- to centimeter-level positioning on your Android-powered device through a simple monthly subscription.

Before you begin...

To run this app, you will need:

  • A Trimble user account
  • A Trimble Catalyst subscription assigned to your username
  • A Trimble Catalyst DA1 digital antenna
  • A compatible Android powered phone or tablet

For more information on the Trimble Catalyst service, purchasing subscriptions, and where to buy a Trimble Catalyst DA1 antenna, visit https://catalyst.trimble.com.

Getting started with Trimble Mobile Manager

  1. Install the Trimble Mobile Manager app directly from the Google Play Store.
  2. Launch the app by tapping the Trimble Mobile Manager icon, and sign-in using your Trimble Mobile Manager with your Trimble username. Accept the Android permissions. If you don't have a Trimble username, you can create one from the app by tapping the Create a new TID link, and following the instructions.
  3. The first time you run Trimble Mobile Manager and before you can start using Trimble Catalyst, you will need to install the Trimble Catalyst Service app.
    To install: tap on the Main menu , then tap System. Tap the Install button to be directed to the Trimble Catalyst Service on the Google Play Store.
  4. Configure and attach the Trimble Catalyst DA1 antenna to your device. Refer to the DA1 Quick Start Guide for set-up options.
  5. Tap the Main menu, then select Connect & Share, then tap the Connect with Trimble Catalyst slider to connect to your DA1 antenna and start Trimble Catalyst. Trimble Catalyst will start and attempt to establish a connection to your antenna.
    Note: Android requires you to allow the connection each time you re-connect to a USB accessory or device. When the Trimble Catalyst Service dialogue pops-up on the screen, tap OK to grant access and proceed.
  6. When Trimble Catalyst starts, GNSS corrections are automatically applied using the Trimble Corrections Hub. GNSS status and error estimate are shown at the top of the Positioning tab.

    Red: No position, or poor position quality.
    Yellow: Moderate position quality.
    Green: Excellent position quality.
Note: For optimal operation, Trimble Catalyst requires a good clear view of the sky free of obstructions and reflected GPS signals (e.g. off buildings and walls). Where possible, avoid working near tall buildings and vegetation. Keep the antenna flat and pointing towards the sky when in use, and where possible elevate the antenna above your body.

Enable other apps to use positions from Trimble Mobile Manager

  1. Enable Developer Options on your Android phone or tablet. Refer to your device manufacturer's documentation on how to enable this mode through the device's Settings App
    1. In the Android Operating System, tap Apps > Settings > Developer options > Select mock location app, then tap Trimble Mobile Manager to select it as the application to provide locations to your device
  2. In Trimble Mobile Manager, tap the Main menu, then tap Connect & Share, then in the Share location section, tap the slider to enable Share positions mode.
Note: This setting is only needed for third-party applications. Trimble Partner apps using Trimble Mobile Manager with the TPSDK do not need to use the Mock Locations service to work with Trimble Catalyst.

Note: Trimble Mobile Manager adds metadata to location extras. A list of all available keys can be found in the developer document.

Configure third party local GNSS corrections

If you are working in an area outside of Trimble's VRS Now coverage zone with a Catalyst Precision subscription level, you may want to configure and use your own GNSS correction source.

To configure and use a custom (local) GNSS correction source:

  1. Tap the Main menu , then tap Corrections
  2. Turn off the Trimble Corrections Hub slider
  3. Enter the server and account details as provided by your local GNSS corrections provider
  4. Select a GNSS source reference frame. This information is provided by your VRS network operator. If you are unsure of which reference frame to use, select Auto selection. Trimble Mobile Manager will select a suitable frame for you based on your current location.
  5. Tab the Back button on the device to return to Trimble Mobile Manager Home Screen, or use the Main menu

Set Distance unit and GNSS output reference frame

If you want to have a consistent coordinate output while using different correction sources or use coordinates in a different reference frame from your correction source frame, you can set an Output reference frame.

To configure an Output reference frame:

  1. Tap the Main menu , then tap Corrections
  2. Tap the Distance unit field to set units for coordinate height
  3. Tap the GNSS output reference frame detection mode field
  4. Select an option from the list
    1. Same as source (Transformation off)
    2. Auto selection
    3. Select from list (choose a reference datum from the dropdown list)
  5. Tab the Back button on the device to return to Trimble Mobile Manager Home Screen, or use the Main menu

If the local correction source frame you are using is not listed, then you can select "Same as source (Transformation off)" as the output reference frame. This forwards any positions as received in terms of your local correction source reference frame.

Setting an output reference frame also sets the output EPSG code, which can be queried and used as position meta-data for other Catalyst enabled applications utilizing Trimble Mobile Manager. For more information on EPSG codes and their use, refer to the official website http://www.epsg.org/.

Note: The EPSG code is undefined for a position collected using the "Same as source (Transformation off)" method.

If you are unsure of which reference frame to use, use Auto selection. Trimble Mobile Manager will select a suitable frame for you based on your current location.

If the output reference frame and source reference frame are the same, then no transformation is applied.

Output and source reference frame behaviour

GNSS output reference frame:

The purpose of the Output reference frame setting is to achieve consistent coordinate output, i.e. to compensate for shifts introduced by frame or epoch shifts. The following Target reference frame options are available:

  • Same as source (Transformation off): Trimble Mobile Manager passes through positions as received by the receiver (whether they are corrected or not), and any logic associated with querying the source reference frame and transforming positions to a different target reference frame is deactivated. Trimble Mobile Manager hasn't transformed the position, so doesn't display a target reference frame or EPSG code.
  • Auto selection: Trimble Mobile Manager queries the current position to look up the reference frame you are most likely in based on internal polygons of known frames. It enables the app to provide a consistent output without any configuration.
  • Select from list: Trimble Mobile Manager allows the user to select a target reference frame datum from a list of available datums.

GNSS source reference frame:

The purpose of the GNSS source reference frame setting is to identify the reference frame used by a third party NTRIP caster when Trimble Mobile Manager is configured to use custom local corrections instead of the Trimble Corrections Hub. In contrast to global correction streams like SBAS or Trimble RTX, the reference frame of a local correction stream can't always be auto-populated with 100% accuracy. The following setting provides the option for Auto selection, or for the user to select a reference frame from a list of known reference frames:

  • Auto selection: this tasks Trimble Mobile Manager to analyze the user's current position and to look up the reference frame based on internal polygons of known frames. This setting works in most regions.
  • All others in the list: if you know the reference frame or your local correction source, this setting allows you to choose a reference frame from a predefined list. Typically a local correction source will work in one of these frames. If your required reference frame is not noted, contact catalyst_support@trimble.com so the list can be enhanced.

View your account and subscription details

To view your subscription details tap, then tap Account & Subscriptions

  • Account name - the Trimble user account you are currently signed in as.

Generating a log file for support purposes

If you need technical support or additional trouble-shooting, contact your local Trimble distributor. They may request that you generate a log-file to help trouble-shoot any problems you may be experiencing with Trimble Mobile Manager or the Trimble Catalyst service on your device.

Trimble Mobile Manager can capture a log file that records status messages and crash details. The log file can be used by the Trimble technical support team to help identify where any problems with Trimble Mobile Manager may be occurring. The log file is completely anonymous.

To generate and send a log file from Trimble Mobile Manager, tap the Main menu, then tap Help & Feedback, then tap Send Email.

Your Android device will invite you to tap an icon of the app you want to use to share the log data with others. For example, you may wish to send the log file to a Google Drive folder, to a DropBox account, or to email it directly. Tap the icon of your preferred email client to generate an automatic email that includes a ZIP attachment of the log file, as well as a system summary for your Android device. The email will be automatically addressed to the Catalyst Support team.
