Spirent Solves Three Big Challenges in LEO Constellation Design and Development

Business is booming in Low Earth Orbit (LEO). ABI Research predicts that up to 2,400 new LEO satellites will be launched in 2023, joining the 4,500 already in orbit, and with the number approved for deployment reaching 30,000 by the end of the decade. Meanwhile, the number of subscribers using LEO satellite services is set […]

How to Minimize Latency in a Hardware-in-the-Loop PNT Testbed

A GNSS simulator is an essential test instrument for dynamic platforms of all kinds. The simulator produces replica GNSS signals that are controllable and repeatable, allowing the assessment and qualification of PNT systems such as GNSS receivers. For applications where PNT capabilities are safety- and liability-critical, one goal of the test regime should be to […]

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 […]
