GPS receiver is an important hardware in measurement operation. Its function affects the feasibility of measurement and the reliability of measurement results. Beidou high precision measurement receiver used in Everest measurement is an unconventional application in extreme environment. The required connector products must be able to cope with environmental challenges such as extreme low temperature, 30KPa low pressure, ice melting and snow melting. At the same time, it has both high reliability and high precision of transmission.

Satellite timing equipment is an important device for achieving time-frequency unity between different platforms, systems, and user terminals. High precision timing equipment can effectively improve the operational efficiency and stability of the system, and reduce the impact of time errors on equipment operation. Therefore, in the fields of electricity, financial transactions, public transportation, mobile communication, etc., the accuracy and reliability of satellite timing equipment are crucial.

Satellite navigation measurement antenna is a new type of satellite antenna, commonly known as mushroom head antenna. The antenna body is composed of metal patches, metal flooring, and RF cables. Based on Global Navigation Satellite System (GNSS) positioning technology, satellite navigation measurement antennas can achieve centimeter level accuracy measurement and positioning in complex environments. At present, it has been widely used in scenarios such as geodetic surveying, ocean surveying, waterway surveying, dredging surveying, earthquake monitoring, bridge deformation monitoring, mountain landslide monitoring, and automatic dock operations.

Satellite telephone is a type of communication device based on satellite communication systems to transmit information. Compared to ordinary telephones, satellite telephones have a long communication distance, large communication capacity, and are not easily limited by any complex geographical conditions, natural disasters, or human events between the two communication points. When facing special application scenarios such as emergency relief, extreme weather, and maritime operations, satellite communication mobile phones can achieve true blind spot free communication.

GNSS refers to a global navigation satellite system based on artificial Earth satellites. Through GNSS receivers, the system can provide accurate geographic location, velocity, and time information in any part of the world and near Earth space, achieving navigation and positioning of moving carriers.

Traditional satellite positioning systems have weak signals and are easily occluded and interfered. It is difficult to accurately locate and navigate in high-rise buildings, narrow alleys, or environments with multiple signal base stations. With the completion of the global deployment of Beidou satellites, Beidou navigation products are about to face comprehensive optimization. Beidou navigation products are required to complete positioning and navigation tasks stably and reliably in a variety of space environments, electromagnetic environments, dynamic environments, and temperature environments. Therefore, related connector products must have excellent performance such as anti-interference, high precision, and high sensitivity at the same time.
