How Can Multi-Constellation GNSS Improve Flight Stability and Positioning Accuracy for Your UAV Systems?

The LS2003xU-G series provides simultaneous GPS, GLONASS, GALILEO, and QZSS tracking with SBAS augmentation, ensuring your drones maintain reliable positioning even in challenging environments with limited sky visibility. With fast TTFF at low signal levels and built-in multi-tone interference cancellation, your UAVs achieve rapid satellite lock and stable navigation performance. Contact our technical team to discover how our compact 30x30mm smart antenna modules can enhance your drone positioning reliability and reduce integration complexity.

Available in three interface configurations—LS20030U-G (USB), LS20031U-G (TTL), and LS20032U-G (RS232)—these modules offer flexible integration options for automotive navigation, UAV/drone systems, handheld devices, marine navigation, fleet management, and surveying applications. Each variant features built-in data logger capability, ±11ns high-accuracy time pulse (PPS) for timing applications, LED indicator for positioning status, and micro battery backup for rapid satellite acquisition. Operating across -40°C to 85°C with low power consumption (29-45mA depending on variant), the LS2003xU-G series delivers the high sensitivity and robust performance required for mission-critical location-based applications worldwide.
