1 summary

This document specifies the product specifications for the SWT-AJU-X200 sixteen-element navigation anti-jamming all-in-one device (hereinafter referred to as the 'anti-jamming all-in-one device').

The anti-jamming all-in-one system consists of an array antenna, anti-jamming processing module, built-in receiver, and supporting cables. It supports 16-channel signal reception, amplification, down-conversion, filtering, anti-jamming processing, and up-conversion output for BDS_B1, GPS L1, and Galileo E1 frequency signals. The built-in receiver provides PVT (Position, Velocity, Time) calculation output. Powered by 9V-36V DC, it features 1-15-directional interference suppression capabilities including broadband, narrowband, pulse, and sweep frequency jamming.

1 Product specifications

3.1 major function

1 ) Supports receiving signals from BDS_B1, GPS L1, and Galileo E1 frequency bands.

2 ) It has the ability to suppress various types of interference, including broadband, narrowband, sweep frequency, and pulse interference, in the B1, L1, and E1 frequency bands, as well as the capability to resist combinations of these interferences.

3 ) Supports both soft direct-through and anti-interference modes, allowing users to flexibly switch between them via the serial port.

4 ) The built-in receiver can output the positioning solution after anti-interference processing.

3.2 the key technical indexes

1) frequency immunity

（1）Channel count: 16 channels, supporting BDS_B1, GPS L1, and Galileo E1 bands.

（2）Anti-jamming capability: Capable of suppressing various interference types including broadband, sweep, and pulse in the B1/L1/E1 frequency bands, with resistance to combinations of these interference types.

（3）The number of anti-interference is 1～15 different direction interference sources;
