1002ASF Airborne SD Short Delay Video transmitter

1.Product introduction

Sagetown 1002ASF（Model No：ZT1002ASF）is a digital wireless video transmitting device developed by Beijing Sagetown Technology Co., Ltd. especially for UAV. The international advanced modulation technology and special design for UAV make ZT1002ASF an ideal choice for remote video wireless transmission applications of various fixed-wing aircraft, helicopters, UAV, UGV and other special vehicles.

ZT1002ASF is adaptable to the carrier speed( the speed of vehicle on which it is mounted)  up to 380 km/h and it also meets the requirements of various low-speed fixed-wing aircraft, helicopters, UAV, UGV and special vehicles.

The whole system is mainly composed of airborne video transmitter (ZT1002ASF), base station video receiver (ZT3000F) and necessary accessories (including antenna feed system, connection lines and connectors, etc.) 

The system can transmit one DVD quality video、one stereo audio and one way transparent serial data such as Beidou or GPS positioning information. AES encrypted transmission guarantees transmission security effectively.

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

ZT1000ASF can transmit up to 2.5 W and provide very robust communication links.

2.Product features

●Transmission of one-way HD video（720×576）

●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
