GEMS NAVIGATION was established in 2007, professionally designs, products and sales of coaxial microwave devices and equipment. GPS indoor coverage systems and accessories, high-power coaxial attenuators, high-power coaxial load, we accumulated many years of designing and manufacturing experience, our own designed and product of GPS indoor coverage systems and related GPS power splitter and amplifier, GPS antenna and other products widely used in microwave communications, mobile communications, high-precision measurement, power, research institutions, colleges and universities, manufacturing and other fields.

GSP splitter products are widely used in the major communications equipment manufacturers of domestic and international , and which are also running on 4G network around the world , to solve shared problems of GPS antenna technology .

Coaxial attenuators and coaxial load, with excellent performance, high parity cost, access to a wide range of applications in the telecommunications equipment manufacturers of domestic. And we also gain market share through international agents.

We have a more than 10 years of microwave communication designing and manufacturing experience team, we are not only based on the technical excellence of our own products, and continuous learning and practicing advanced technology at home and abroad to strengthen exchanges and cooperation with the latest advanced technology, cast a high-quality R & D team and management team at the same time conducive to the rapid development of the company, laid the company's position in the domestic market, but also my company's image and corporate image to a broader international market , has won praise from the domestic and foreign counterparts.

Through the depth of cooperation with international counterparts: the United States GPS SOURCE, ANTCOM and other companies, we have gained experience in the application of the field of RF and microwave signal and the actual project case. We do not just serve the domestic leader in mobile communications: Huawei, Alcatel-Lucent, Nokia Siemens Networks, Datang Mobile, China Mobile, China Telecom and other Global 500 companies; we have a large global electronics contract manufacturing companies: Hon Hai , Asus, Warburg , Compal and other giants of the testing program and we also establish a long-term supplier relationships; test program for Global smartphone company: APPLE , Samsung, SONY , Lenovo, BBK, Gionee; domestic mobile phone solutions company: Simcom, SIMCom, Huaqin, Sagetel,Cellon, Kai Sin as well as numerous mobile phone manufacturing companies; colleges and universities in the country: University of Defense Technology , Wuhan University , Beijing University of Post and Telecommunication, Dalian Maritime University, Zhejiang University, University of Electronic Science and Technology of China., Chengdu University of Electronic Science and Technology, Shanghai Maritime University and so on;Provide GPS signal products and microwave devices for the military industrial enterprises in China and major Researches.

In the GPS measurements of domestic , we serve the local hospital mapping: the Jiangsu Academy of Surveying and Mapping, Surveying and Mapping Institute of Shandong Province, Shanxi Academy of Surveying and Mapping, Beijing Surveying and Mapping Institute, China National Time Service Center.

In the security field of public transport, we provide GPS full coverage for the parking lot of Tianjin high-speed rail station,and Beijing high-speed rail station ; We also provide GPS full coverage for the city's bus parking of Chengdu and Changsha .
