1. Product Introduction

      ZT1001AHSH is a HD digital wireless video transmission device especially developed by Beijing Sagetown Technology Co., Ltd. for UAV. ZT1001AHSH has become the ideal choice for the application of long-distance data link of all kinds of low-speed aircraft, high-speed aircraft, unmanned vehicle and special vehicle because of its advanced modulation technology and specific design for unmanned aerial vehicle

      ZT1001AHSH can be operated with the carrier speed (on which the equipment is mounted) as high as 380 km/h and it also meets the moving speed requirements of various low-speed fixed-wing aircraft, helicopters, UAV, UGV and special vehicles.

      The system is mainly composed of airborne image transmitter (ZT1001AHSH), base station image receiver (ZT3000R) and necessary accessories (including antenna feed system, connection lines and connectors, etc.).。

      The system can transmit one HD video at the same time (1920 x 1080p). AES encrypted transmission can effectively ensure the transmission security.

      The Zhengtang (ZT) series wireless image transmission system launched by Beijing Zhengtang Science and Technology Co., Ltd. adopts narrowband modulation technology. On the one hand, it provides unprecedented spectral efficiency; on the other hand, it increases the system reception sensitivity, thus expanding the transmission distance.

      ZT1001AHSH can transmit up to 1W and provide very robust communication links.

2. Product features

● Transmission of one-way HD video (1920 x 1080p)
● NLOS transmission can work reliably in occlusion environment.
● High-speed mobile transmission, adapted to carrier speed(on which the equipment is mounted) up to 380 km/h.
● The delay of the system is about 70 ms, and it is almost real-time transmission, which fully meets the real-time control requirements.
● AES Encrypted Transmission, Effectively Prevent the Illegal overtake.

● Narrow-band modulation technology which guarantees the transmission bandwidth without shortening of the transmission distance.
