The Trimble Catalyst system consists of various components – each responsible for dedicated tasks:

Trimble Mobile Manager available in Google Play Store

Trimble DA1 antenna


Trimble Mobile Manager

Trimble Mobile Manager (TMM) is your gateway to the Trimble Catalyst universe.

TMM takes care of all subscription related tasks like pulling information from the server or keeping subscriptions up to date. TMM also installs the Trimble Catalyst Service – the number crunching engine that is the core element of the GNSS engine.

Furthermore it allows trouble shooting issues in the field via advanced log options (see documentation for details).

For users of the Trimble Catalyst system TMM offers various information about the current position status such as:

A satellite overview page
Options to customize NTRIP settings
Purchased subscription overview

It also helps a developer via various Android Intent services such as:

Performing a login on behalf of the calling application
Showing an information page on behalf of the calling application


Trimble DA1 antenna

The Trimble DA1 antenna (digital antenna) is the antenna used for Trimble Catalyst.
It’s a lightweight, robust and affordable antenna with specs close to a high-end receiver.
It’s a dual frequency antenna with support for the most common tracking signals, plus supports Trimble RTX technology.

More details on the Trimble DA1 can be found in the data sheet or the corresponding Trimble Community page.



Trimble Precision SDK for Catalyst

The Trimble Precision SDK has its roots in Windows but was ported to Android to solve the needs in the corresponding markets.

The Trimble Precision SDK for Catalyst (TPSDK for Catalyst) contains known Windows libraries (like Sensor Software Interface – SSI) and a selection of code samples that you can use when you create applications supporting Trimble Catalyst.

In contrast to the Windows flavor of TPSDK, the Android flavor focuses ease of use. Therefore additional wrapper layers (called Facades) have been added to demonstrate how to utilize TPSDK effectively and with only few lines of code. The Facades are available in both project and source code form – and can be directly dropped into your solution to provide an easy-to-use API interface.

You can use the TPSDK for Catalyst, along with your chosen development environment (Microsoft Xamarin for Android or Java), to connect and control not only the Trimble Catalyst soft GNSS receiver, but also traditional GNSS receivers.


All this comes at a certain price – namely the hardware and software requirements of the Trimble Catalyst system. As Trimble Catalyst performs a reasonable amount of mathematical operations the system requires a certain level of power so we can ensure you always get the precision you pay for.



The Trimble Catalyst solution contains a software-based GNSS engine targeting Android phones.
It therefore needs a certain amount of CPU power to compute positions which need to be available at all times.

The minimal software/ hardware specification for a device running Trimble Catalyst is:

Android API level 20 or higher (Android 5.0 aka KitKat)
ARM architecture
Snapdragon 801/ equivalent or higher
1400MHz or higher
1500MB RAM

The recommended software/ hardware specification for Trimble Catalyst is:

Android API level 23 or higher (Android 6.0 aka Marshmallow)
Android 64bit flavor
ARM architecture 64bit
Snapdragon 821/ equivalent or higher
1800MHz or higher
2000MB RAM



Trimble ID

Trimble Catalyst is a subscription-based system. A subscription is tied to a user or more precisely their Trimble ID (TID) which can be created free of charge.
A TID must be in place when connecting to any type of receiver as the TID acts as authorization. More details on this can be found in the documentaiton.


Trimble Mobile Manager

As already mentioned Trimble Mobile Manager (TMM) is your gateway to the Trimble Catalyst universe. It not only helps both user and developer to download a valid subscription but it also allows e.g. sharing a position via the Android Location API or updating your antenna firmware.

Trimble Mobile Manager can be downloaded from Google Play Store.
