The Trimble Catalyst GNSS antenna and a selection of accessories can be purchased through your local Trimble Distributor.
The Catalyst DA1 antenna is used to provide high quality GNSS data to your phone or tablet. The antenna simply attaches to your Android device via USB cable, which is also used to deliver power to or from the antenna. The DA1 antenna ships with the following standard items.
Trimble Catalyst DA1 Antenna
(with microUSB data cable and push-fit adapter)
External rechargeable USB battery pack
Battery pack pole mount for 1.25" diameter poles
Trimble branded canvas antenna carry pouch
The DA1 antenna attaches to your phone via USB. The antenna is designed to work with phones with a microUSB port or with a USB Type C port (with a cable adapter).
Important Note: Not all USB adapters support two-way communication between the phone and a connected device. Trimble recommends only using the specific Trimble Catalyst micro-B to type-C USB converter (PN 114199) which ships as a standard accessory with the DA1 antenna. This accessory is also available exclusively from your Trimble Catalyst stockist as a replacement part. The adapter attaches directly to the end of the Catalyst DA1 antenna cable for use with USB Type-C equipped devices.
If you prefer to use an off the shelf option, the Huawei AP52 adapter has been tested and fully supports Catalyst's USB communication requirements. Other off the shelf USB Type C adapters are not recommended or officially supported.
The DA1 antenna is designed to be versatile and easily mounted or carried in different configurations. Out of the box, the DA1 is supplied with a rubber push-fit mount, which allows the antenna to easily attached to any 1-¼ inch diameter rod or pole (including the Trimble 2m aluminum flat-topped rod, designed specifically for the DA1 antenna PN 109219). The DA1 is also supplied with a ⅝ inch threaded adapter, which allows your antenna to be attached to any standard surveying accessory with a compatible ⅝ inch screw thread.
The DA1 Mounting Accessory Kit (PN 114095) lets you explore even more options for mounting your DA1 antenna for different use cases. The kit contains the following components:
The locking-fit adapters provide a more secure and accurate method for attaching the DA1 antenna to ⅝ Inch survey rods for applications demanding repeatable and highest levels of accuracy. Once attached, these adapters are locked in place providing both a secure attachment and a more controllable method of fixing the antenna height. The "Tall" version provides additional clearance below the antenna to route the antenna cables for scenarios where the antenna is being mounted on a flat surface (for example attaching the antenna to the roof of a vehicle).
The ¼ inch push-fit thread adapter is ideal for mounting the DA1 antenna to standard camera pole accessories or other hardware with a ¼ inch diameter screw thread.
Other Trimble accessories as listed below can also be purchased individually as spares, replacements, or as optional extras to meet the needs of your application.
There are a huge range of styles and sizes of smartphone and tablets that you can use with Trimble Catalyst. Contact your device vendor for mounting and carrying options that are compatible with your device. For range pole mounting, Trimble recommends the modular X-grip series of rugged device mounts available from RAM Mount. Contact your nearest Trimble Distributor for their recommendations and suggestions available in your region.
Depending on your application and Trimble Catalyst subscription, you will have different needs for how you mount or carry your phone, tablet, and Catalyst antenna. There are many options on how to do this from third party suppliers, including RAM Mount, SECO surveying equipment, and online vendors such as Amazon. Contact your nearest Trimble Distributor for their recommendations and suggestions available in your region.
Trimble Catalyst can run on compatible Android phones and tablets but due to the processing requirements may not work on older model devices. We have provided some guidelines below to help you understand if your device will meet the minimum hardware specifications.
Trimble Catalyst connects to the DA1 antenna through the USB port on your phone or tablet. In order to power the antenna from your device's battery, your device needs to support "USB-OTG". If your device does not support USB-OTG, you can still connect and use Trimble Catalyst by powering the DA1 with the external battery pack supplied with your antenna.
Android devices with a USB Type-C connector require a USB-C adapter to operate with Trimble Catalyst. Trimble recommends the Huawei AP52 Micro USB to USB Type-C Adapter (PN AP52-W-BK).
To check if your device is compatible, download the Trimble Mobile Manager app from the Google Play store. The Trimble Mobile Manager app will check your device's performance capabilities against Trimble Catalyst requirements.
