For the signal transmission, identification and processing technologies of Ku-band satellites, the system can realize full-domain scanning and accurate acquisition of the target satellite signals by virtue of a dedicated receiving antenna, a low-noise block downconverter (LNB) and a digital signal processing unit. It then rapidly locks onto the target Ku-frequency transmission signals through signal feature extraction, beacon frequency identification and other means, and achieves continuous dynamic tracking of the motion trajectory of the target satellite (or user terminal), thus ensuring the continuity and reliability of signal reception.
This specification specifies the core requirements for the XL-UP signal detection including its functions, performance, interfaces and operating environment, serving as the basis for product research and development, testing, production, procurement and customer acceptance.
Supports long-distance unobstructed satellite terminal detection over 10 km.
b) Signal Recording and Playback
Supports real-time recording and playback of detected signals; once a signal is detected, the original data signals are recorded, played back and stored (response time is consistent with the detection response time, ≤250 ms), with a continuous recording and playback duration of over 1 s.
c) Touch Screen Display
3.2-inch LCD screen is equipped, supporting the control of device detection and recording/playback, and displaying detection information.
d) Voice Announcement
Integrated with a TTS voice broadcast chip, supporting human voice broadcast of detection results; supports wireless broadcast via Bluetooth earphone connection.
e) Wired Communication
1 Gigabit Ethernet port, supporting TCP/IP, UDP, ICMP and other protocols
f) Wireless Transmission
Supports WIFI connection with devices and 4G module transmission.
