In the modern information society, the construction of communication network, electric power network, financial network and transportation network is increasingly dependent on time and frequency. Time synchronization technology with high precision and high reliability is the key to the normal operation of each network system. Satellite timing has become a widely used time synchronization technology due to its high accuracy, wide geographical coverage and ease of use, and plays an important role in communication, electric power and financial industries. Unicore's self-developed GNSS timing module can provide nanosecond-level timing accuracy to meet the high requirements of time synchronization. The modules adopt advanced interference suppression technology and RF structure design, which are more adaptable to complex electromagnetic environment. The diversified application configuration meets the requirements of different industries.
