- General Purpose External Antenna Module
External antennas offer greater design flexibility, providing more opportunities to customize the radiation pattern or bandwidth. These antennas do not need to be directly attached to IoT or RF devices and can be positioned in optimal locations at appropriate distances using coaxial cables. They are available in various styles and configurations.

 

- General Purpose Embedded Antenna Module
Embedded antennas are designed to save space and reduce costs while maintaining good performance. They offer a clean, self-contained package with no external attachments, making them ideal for compact devices that require high-performance standards while adhering to strict size constraints.

- Dual-Band GNSS (L1/L5) Module
The dual-band GNSS module operates on multiple frequencies, enhancing positioning accuracy by providing consistent track logs. By receiving signals on more than one frequency from each satellite, it reduces the impact of environmental interference, making it particularly effective in complex environments.

- UDR (Untethered Dead Reckoning) Module
UDR is a method of continuous navigation that uses sensors to calculate the distance traveled from a known position. It estimates the current location by combining speed, heading, and elapsed time. UDR is particularly useful in environments where GNSS signals are obstructed, such as buildings, tunnels, and underground parking lots, where positioning accuracy is typically reduced.
