2021/04/08 Rockwell Collins has received a 2 million contract from the Air Force Research Laboratory (AFRL) to develop and demonstrate a secure software-defined radio (SDR) GNSS receiver capability. GNSS typically refers to equipment that can receive signals from multiple navigation satellite systems including GPS, GLONASS, Galileo, and the Chinese BeiDou system. By utilizing multiple available satellite signals, a GNSS receiver can provide improved navigation performance and signal availability. Hosted in a software-defined radio, this AFRL program will develop the security architecture required for the receiver equipment certifications. The arrival of modernized GPS signals and other constellations is changing the way the U.S. military accomplishes GNSS-based positioning, navigation and timing. “Rockwell Collins is actively researching GNSS capability as it applies to the U.S. and global customer base,” said John Borghese, vice president of the Rockwell Collins Advanced Technology Center. “We’re leveraging decades of GPS experience and leading edge security architectures to produce a navigation receiver that will meet global needs.”
