ZST Digital Networks, Inc. Files Patent Application for Its Assisted GPS Technology

ZHENGZHOU, China, June 20, 2011 /PRNewswire-Asia-FirstCall/ -- ZST Digital Networks, Inc. (NASDAQ: ZSTN) ("ZST" or the "Company"), a major developer, manufacturer and supplier of digital and optical network equipment to cable system operators and provider of GPS tracking devices and support services for transport-related enterprises in China, today announced that it has recently filed a patent application with the Chinese State Intellectual Property Office (SIPO) to ensure intellectual property protection for its Assisted GPS technology.

The Company's commercial GPS fleet management tracking and positioning devices are an internet-based system with numerous features, including but not limited to real time GPS tracking and monitoring, WEBGIS platform with live updated maps, alternative positioning systems and other value-added functions such as speed limiting and vehicle exhaust emission testing. These features are well applied to government efforts to promote higher environmental standards and energy conservation.

Assisted GPS, or A-GPS, is a technology used to improve the performance of traditional standalone GPS tracking systems which rely solely on radio signals from satellites and can be impacted by poor signal conditions in certain environments, for example in dense urban areas.

A-GPS systems overcome this issue by utilizing network resources, such as data available from a mobile network.  Without requiring any additional hardware, ZST Digital's A-GPS system can make use of the GSM modules and location based service (LBS) capabilities of customers' existing mobile phone equipment, in conjunction with additional software, to introduce LBS capabilities to the GPS system, forming a dual-positioning mode.  As such, when customers encounter satellite signal blockages or electromagnetic interference, the A-GPS system will enable the mobile phone LBS function to act as an assisted tracking tool, providing unimpeded tracking and navigation services.        

Mr. Zhong Bo, Chairman and Chief Executive Officer of ZST, commented, "By seeking to patent our value-added Assisted GPS technology, we are securing the continued viability of our proprietary commercial GPS fleet management tracking system. A-GPS functionality allows our customers to take full advantage of our commercial GPS tracking systems regardless of environmental conditions, resulting in improved service and functionality.  Our GPS commercial fleet management tracking segment has quickly become a major contributor to our overall business, with clear growth opportunities ahead.  We believe that seeking this patent will help us to continue our expansion and strengthen our competitive position in the commercial GPS market in Henan Province, in addition to reinforcing a barrier to entry and further validating ZST's technological capabilities."
