Product Details
1. Product Description
SR1004-M antenna control system is a network-based antenna pointing control system. This system supports various network communication methods such as serial ports, network ports, and optical ports. Compared with traditional signal control systems, it has significantly improved in multiple aspects including stability, system response time, anti-interference ability, compatibility of terminal control equipment, and scalability. In terms of system monitoring, upgrading, and maintenance, remote operations based on the Internet or local area network can be achieved, and a software one-click upgrade interface is provided to users
Stepping tracking accuracy
It is superior to the receiving wave velocity width by 10% in an environment with a wind speed of 30 meters per hour and a gust of 45 meters per hour.
Pointing accuracy
It is superior to 0.05︒ RMS in an environment with a wind speed of 30 meters per hour and a gust of 45 meters per hour. The above pointing accuracy does not include the errors caused by the antenna structure.
