The AISG On-Off Keying (OOK) interface was developed to enable data communication for command and diagnostics between a base station and mast-mounted equipment. Although most existing AISG OOK implementations rely on discrete designs, recent developments in integrated transmitter/receiver devices have opened up new possibilities for more streamlined designs. This article explores the tradeoffs between traditional discrete and newer integrated implementations of AISG OOK modems, focusing on both board-level and system-level changes. Block Diagram and Overview In an AISG OOK modem interface, the transmitter generates modulated signals from logic inputs, while the receiver demodulates RF signals into logic levels. Both implementations,…

Radiometrics, through its acquisition of DeTect Meteorological Systems Group, was chosen to replace the outdated radar wind profiler (RWP) system at NASA’s Kennedy Space Center. For years, NASA had relied on weather balloons to monitor upper-level winds, with their aging RWP serving as a backup. However, NASA’s heavy-lift rocket programs needed more precise and current wind data, driving the demand for a modern, reliable RWP system. The new system is designed to last for the next 20 years. Radiometrics was tasked with upgrading NASA’s old radar infrastructure. During the process, they recognized the need for a specialized antenna manufacturer that…
