Norsat’s article, “Block Upconverter Design Considerations for Airborne Applications” was published in the recent issue of Microwave Product Digest magazine. The recent breakthrough in satellite communication services has provided limitless communication options for airborne applications. With the right equipment and worldwide services, one can provide secure, consistent, two-way broadband communications to various types of airborne missions. This includes mobile Command & Control services (C2); tracking of VIPs and dignitaries; live Intelligence, Surveillance, Reconnaissance (ISR) or any type of in-flight emergency communications. Since airborne applications are unique, there need to be special considerations in the design of block upconverters to truly provide complete control beyond the horizon and seamless “eye-in-the-sky” support.
