Permanent Link to Spectracom Extends Local Service to the Asia-Pacific Region
Spectracom, a business of the Orolia Group, has extended its global service capability through a partnership with EZU Technologies. Joining Spectracom service centers in North America and Europe, EZU Technologies will support Spectracom users throughout the Asia-Pacific region from its facility in Hong Kong. Initially, services will include equipment calibration and repair services. Over time, more capability will be added to deliver Spectracom’s full range of services in the region.
Spectracom’s portfolio of GNSS signal management solutions include a variety of services to ensure their customers gets the most out of their application for positioning, navigation and timing. “We understand our customer’s needs for fast access to services. Our strong growth in Asia, particularly for GNSS simulation and enterprise-class timing, will be supported by localizing services in the region,” said Thierry Delhomme, general manager, Spectracom Europe.
This new service center is the first of several partnerships to deliver global services in support of Spectracom solutions. Lisa Withers, Spectracom President and CEO, said, “We are pleased to expand our existing partnership with EZU Technologies to develop a regional service hub. This will enhance the local service provided by our strong set of local distributors and resell partners throughout the region.”
