Unlocking the Potential of Commercial Satellite Navigation with SimXona

Commercial low Earth orbit (LEO) satellite constellations have the potential to introduce new positioning, navigation and timing (PNT) signals to complement existing global navigation satellite systems (GNSS), providing resilience, security, and high precision to navigation users. More than 20x closer to Earth compared to medium Earth orbit (MEO), providing stronger signals from LEO is attractive […]

Latency: What It Is and How It Can Affect Your PNT Test Environment

Dynamic platforms of all kinds—from driverless cars to military drones—depend on accurate and reliable positioning, navigation and timing (PNT) technologies to ensure mission success. An advanced way to maximize PNT accuracy and reliability in such vehicles is to use a multi-sensor system, in which sensors like cameras, LiDAR and inertial measurement units (IMUs) work in […]
