GPS module description:
L76K is a GNSS module that supports multi-satellite systems (GPS, BDS, GLONASS, QZSS), joint multi-system positioning and single-system independent positioning, AGNSS function, built-in low-noise amplifiers and acoustic surface filters, and provides users with a fast, accurate, high-performance positioning experience.
The multi-satellite system makes the number of visible and available satellites increase dramatically compared to a single GPS system, which improves positioning accuracy and enables stable and highly accurate positioning even in complex urban environments. Supports AGNSS function, which can greatly reduce the time of first-time positioning. Built-in low noise amplifier can realize high sensitivity, high accuracy positioning and fast signal capture and tracking, which can ensure the positioning performance even under weak signal conditions. Built-in acoustic surface filter, can greatly enhance the module's anti-interference ability. Internal integrated active antenna detection circuit and protection circuit, can protect the module and active antenna from damage.
