Details
Multiple connector and cable options are available for the BT-4520 series to match different GNSS receiver interfaces.
The BT-4520 supports BDS B1, GPS L1, GLONASS L1, and Galileo E1 in a compact form factor for stable positioning.
Wide supply voltage and low current draw make integration easier in robots, UAVs, and embedded GNSS equipment.
An RHCP patch design with RG1.13 pigtail and an IPEX connector helps keep the installation compact while maintaining signal quality.
Common use cases include measurement instruments, dash cameras, drones, and traffic signal timing or location systems.
