California-based Trimble has introduced a receiver and antenna that improves GNSS positioning accuracy when used near trees and buildings.

The DA2 GNSS receiver and antenna are for Trimble’s Catalyst subscription-based GNSS positioning service and include the firm’s ProPoint GNSS engine for enhanced performance. ProPoint technology reduces convergence times and improves positioning accuracy when operating near trees and buildings.

In addition, the Bluetooth-enabled DA2 adds iOS support to the Catalyst service, increasing the range of devices, workflows and apps that can be used with Catalyst.

The positioning service is for location-enabled field applications. It is available in accuracy-based packages from centimetre- to sub-metre-level for a wide range of mapping and mobile Geographic Information System (GIS) data collection projects. Catalyst continues to support a broad range of GIS field applications, including Trimble TerraFlex software, for form-based GIS data collection.

“Trimble Catalyst brings easy-to-use precise positioning to location-enabled workforces,” said Gareth Gibson, marketing director at Trimble. “The addition of ProPoint technology, together with the DA2’s support for iOS devices, means Catalyst can now deliver Trimble quality positioning to more geospatial professionals than ever before.”

Catalyst subscriptions are available to purchase through Trimble’s authorised distribution network. The Catalyst DA2 digital GNSS receiver, sold separately, is expected to be available before the end of the year. TerraFlex software subscriptions are available separately through Trimble Geospatial distribution partners.

Trimble Geospatial facilitates productive workflows and information exchange for surveyors, engineering and GIS service companies, governments, utilities and transportation authorities.

Trimble’s technologies include integrated sensors, field applications, real-time communications and office software for processing, modelling and data analytics. Using these, organisations can capture accurate spatial data and transform them into intelligence to increase productivity and improve decision-making.

Trimble’s core technologies in positioning, modelling, connectivity and data analytics connect the digital and physical worlds to improve productivity, quality, safety, transparency and sustainability. From purpose-built products to enterprise lifecycle offerings, Trimble is helping industries such as agriculture, construction, geospatial and transportation.
