Progress in developing the Broadcast Positioning System (BPS) was recently charted at the NAB (National Association of Broadcasters) show. CNX Software reports that BPS is being positioned as a backup, alternative, or confirmation data source for the Global Positioning System (GPS). However, BPS has its particular strengths and weaknesses.
GPS can be as vital to some portable smart device users as mobile and Wi-Fi network data. However, this satellite-based system, which provides precise location, velocity, and time information, is not always available and can be interfered with by bad actors. Recent reports of GPS interference over the Baltic Sea, the Black Sea, and the eastern Mediterranean make for worrying reading. On the other side of the conflict, Ukraine is known to have used GPS spoofing to repel Russian drone attacks.
