Explore IDPS™ applications
TERN powers a smooth drive from point A to point B, and all the pit stops in between. IDPS™ works with vehicles’ existing base maps and sensors, improving navigation and location services that help drivers reach their destinations, improve safety, and even obtain emergency services – all without signal.
Urban canyons, signal interruptions, off grid destinations, and obstructions are no issue for IDPS™. Whether delivering packages or providing logistic services, TERN’s tech can boost operational efficiency, increase profitability, and reduce carbon footprint.
IDPS™ delivers mission-critical positioning, navigation, and timing (PNT) information even when traditional communications networks are down, ensuring resilience to increasing threats to GPS from outages, spoofing, and satellite vulnerability.
