AI Technical Summary
Traditional vehicle-mounted antenna modules, lacking signal amplification components, struggle to effectively identify and process weak signals, resulting in weak satellite signals, low signal-to-noise ratios, and decreased positioning accuracy. Their performance is particularly poor in complex urban environments or severe weather conditions.
It integrates a signal amplification module and a control module, receives GNSS satellite signals through a dielectric antenna and performs low-noise amplification processing, combined with a shielding cover to prevent electromagnetic interference, and adopts a split box design and a multi-seal structure to improve signal reception sensitivity and protection performance.
It improves signal reception sensitivity, enhances positioning performance, ensures accurate positioning in areas with weak signals, and also features transmit and receive capabilities. Furthermore, its quick-disassembly design improves maintenance efficiency.
