Understanding latency for hardware-in-the-loop testing

latency 1240x400

Many modern dynamic platforms rely heavily on PNT information, and this information is routinely safety- and mission-critical. With the GNSS receiver typically part of a complex system of sensors, actuators, software applications, and algorithms, developers need to ensure that an integrated product continues to meet standalone performance parameters.

One key method employed is hardware-in-the-loop (HIL) testing. This white paper discusses the different approaches to HIL testing, and how latency impacts the test operation and the results. Find out what latency is, how it is measured, and what the impacts of higher latency are on testing.

In this white paper, Spirent discusses:

  • What is latency?

  • How is latency measured?

  • Different test configurations

  • The importance of latency in highly dynamic application testing

  • The importance of latency in autonomous vehicle testing

  • Choosing the right GNSS simulator for your HIL test rig
