SX-124
Positioning, Navigation, Timing
The SX-124 provides assured positioning, navigation, and timing (A-PNT) capabilities essential for Cyber, EW, SIGINT, and Comms applications in GPS-denied environments. It features onboard GNSS receivers and can utilize external resources for timing and position data, distributing precise timing outputs and synchronizing timestamps. This 3U OpenVPX plug-in card aligns with the SOSA™ technical standards, ensuring seamless integration and reliability for modular open systems approach (MOSA) systems.
Built on Xilinx's UltraScale+™ MPSoC, the SX-124 offers robust processing and real-time control. It supports multiple sensors using the pntOS open sensor fusion software framework, providing accurate timing and positioning in challenging conditions. The SX-124 is ideal for defense and commercial platforms needing dependable navigation and timing information, delivering high precision and performance under the toughest operational demands.
