Abstract

The invention provides a miniature positioning navigation time service terminal. The miniature positioning navigation time service terminal includes an MEMS gyroscope, an MEMS accelerometer, a microprocessor, a micro atomic clock, a GNSS navigation chip and other main functional components; the method of integrated design is adopted, and the high integration and miniaturization of the positioningnavigation time service terminal are achieved. In order to achieve the orthogonal installation of the triaxial MEMS gyroscope and the triaxial accelerometer and the high integration of the terminal and improve the vibration resistance of terminal equipment, a rigid-flex board technology is used for conducting the three-dimensional package of the terminal. The miniature positioning navigation timeservice terminal does not rely on external information, has high independence, and can ensure that a user can obtain reliable positioning navigation time information under the condition of GNSS denial. The positioning navigation time service terminal has the advantages of a small size, low power consumption, high precision, a good real-time performance, strong impact resistance and the like.

Description

technical field [0001] The invention relates to a miniature positioning, navigation and timing terminal, which belongs to the field of positioning, navigation and timing. Background technique [0002] Positioning, navigation and timing (PNT) technology is a key technology for providing time and space information. With the development of science and technology, the dependence on PNT has surpassed any historical period, and when and where is one of the most concerned issues. PNT technology serves the national economy, national security and military fields, and is a remarkable symbol of comprehensive national strength and international status. The United States, Europe, and China have successively formulated national PNT development plans, and are establishing and improving their own or regional PNT systems. [0003] Global navigation satellite system (GNSS) is the most widely used PNT technology. Since the deployment of GPS in 1989, satellite navigation applications have be...
