Mushroom Navigation GNSS Antenna Timing GPS Antenna
Product Introduction
The product is a high-performance active antenna specially designed for vehicle built-in satellite navigation terminals. It supports Beidou B1, GPS L1 frequency band and GLONASS L1 frequency band, and is widely applicable to vehicle navigation and positioning systems.
The antenna adopts advanced antenna design technology and has excellent performance indicators. The gain of the antenna is high, which can effectively receive weak signals and ensure stable signal quality. The pattern beam is wide, and the antenna has good receiving ability and large coverage area, providing more reliable and stable navigation and positioning. The low elevation angle signal reception is excellent, and accurate navigation information can be obtained even in harsh environmental conditions.
The antenna adopts a double-feed point design, which makes the phase center of the antenna perfectly coincide with the geometric center. This design achieves higher positioning accuracy, reduces error factors, and improves the accuracy and reliability of the navigation system.
