Bluetooth technology is an open global standard for wireless data and voice communication, which is based on low-cost short-range wireless connections and establishes a special connection for fixed and mobile device communication environments. Bluetooth operates in the globally recognized 2.4GHz ISM (Industrial, Scientific, Medical) frequency band, using the IEEE802.11 protocol. Bluetooth Role Introduction The main… Continue reading Bluetooth technology: unlimited connectivity, opening up future smart life

1、 What affects the positioning accuracy? Why do different modules have different positioning accuracies? The GNSS module we usually use, also known as a satellite signal receiver, receives observations sent by satellites, which are subject to ionospheric, tropospheric, and ground interference. The accumulation of errors leads to a significant decrease in positioning accuracy. According to… Continue reading Briefly describe RTK high-precision positioning technology

Navigation enhancement technology plays a crucial role in modern satellite navigation systems. It is like a "booster" for satellite navigation, which can greatly enhance the service capability of the system. The information augmentation system is like a precise "data analyst", analyzing satellite data through ground monitoring stations, calculating error correction or integrity information, and then… Continue reading Navigation Enhancement Technology: The Path to Upgrading Satellite Navigation Services

Atomic clock is a key core component for achieving high-precision spatiotemporal reference in satellite navigation systems. The current spatiotemporal reference is established on the ground, and various satellite navigation systems rely on observation data from global or regional monitoring stations on the ground to accurately determine the orbit and clock bias of navigation constellation satellites.… Continue reading Introduction to Atomic Clock Technology, a Core Component of Satellite Navigation
