Введение

Описание

• This product is a wireless high-definition video transmission module designed specifically for UAV communication.
• The latest generation of wireless video communication equipment was independently developed and designed on the basis of integrating the latest terrestrial digital TV technology.
• Its core in the field of wireless communication is advanced LDPC error correction code technology, AES128-битное шифрование, и zero-IF modulation technology.
• It is capable of transmitting high-speed real-time video data in “high-speed motion” и “non-line-of-sight conditions.”
• This product is small in size and light in weight.
• It has a beautiful and reasonable structure design and excellent radio frequency performance.
• A long transmission distance, theoretical (test) distance up to 200km (known practical application distance of 140km), низкое энергопотребление, and long battery life, make it an excellent choice for drone communication.

преимущество

• Передовой: capable of high-speed movement, long-distance travel, защита от помех, and spectrum resource conservation
  • To reduce local noise, the wireless receiving module uses zero intermediate frequency demodulation, с несколькими несущими TDD-COFDM (time-domain synchronous orthogonal frequency division multiplexing), and the same frequency noise reduction algorithm processing technology as the wireless transmitting module. Video images are transmitted in 1080P-60 frames, conserving spectrum resources.
• The communication system that is energy-efficient, environmentally friendly, and spectrum-compatible:
  • The wireless transmission core of the system has a very high peak-to-average ratio on the modulator, and the radio frequency transmission processing uses pre-distortion processing technology. The overall power consumption of the equipment exceeds 30% эффективность, which is significantly higher than the 16% equipment power consumption of the traditional one-way COFDM system. The RF filter employs a multi-stage band-pass filter, which has the excellent out-of-band rejection of RF power output and spectrum compatibility.
• Highly reliable, безопасный, and secure communication system (the system adopts private communication transmission protocol, private synchronization code, и AES-шифрование)
  • Технология шифрования AES 128 бит.: After AES has encrypted the information data, информация до шифрования не может быть получена;
  • Encryption of synchronization code: A 256-bit synchronization code is used for signal timing, carrier synchronization, and frame synchronization; the phase change method of synchronization code employs encryption.

Вопросы-Ответы

1 квартал: This product looks large and heavy. Are you sure it can be used on drones?

This product simply adds a sturdy, waterproof case with four screw holes for the tripod to the transmitter and receiver; if you need to mount it on the drone as a transmitter, you can remove the large case to save weight. As the receiver side, the case is suggested to be kept. https://ivcan.com/p/uav-drone-video-data-link-module-wireless-transmitter/
