Description

Product Presentation

ST65-4 CH ultra-miniaturization anti-interference all-in-one machine is a satellite navigation anti-interference all-in-one machine designed for the needs of small and medium-sized UAVs and other industries. It supports anti-broadband interference capabilities and positioning functions for Beidou B1 and GPS frequency point signals. The device features an internally integrated antenna array, anti-jamming components, and a satellite navigation receiver. It is characterized by its miniaturization, lightweight design, and low cost.

Product Function

1. RNSS Signal Reception
   • Capable of receiving RNSS signals from navigation satellites such as Beidou-3 and GPS.

3. In RF signal access mode, this product replaces the conventional active antenna.
   
4. When using a USB to TTL tool to connect to the computer, do not plug in the USB to avoid damaging the serial port.

Installation and Use

1. Fixed

   Install fixation with M2 screws.

2. Supply Electricity

   Use an XT 30 power supply with a voltage range of 5-17V, not exceeding 17V. It is recommended to use 12V.

3. Locate the Data Connection
   1. Connect the DuPont line TTL serial port of this product to the flight control GNSS serial port.

      Connect the flight control to the GNSS serial port using the matching data line provided by this product. Connect one end of the data line labeled TX to the flight control RX interface, the end labeled RX to the flight control TX interface, and the label GND to the flight control GND interface.

   2. Use the SMA cable to connect the RF port of the product to the antenna port of the UAV locator.

Docking with the Flight Control Protocol

This product can output either NMEA protocol or UBlox protocol. The flight control must be set to receive one of these two protocols. Please ask the customer to complete the agreement on docking work with our technical personnel before placing an order.
