What are the main challenges and benefits of using GNSS/INS for autonomous vehicles?
Autonomous vehicles rely on accurate and reliable positioning, navigation, and timing (PNT) information to operate safely and efficiently. One of the most common ways to obtain PNT data is by using global navigation satellite systems (GNSS), such as GPS, GLONASS, Galileo, or BeiDou. However, GNSS signals are vulnerable to interference, jamming, spoofing, and multipath effects, especially in urban environments, tunnels, bridges, or forests. To overcome these limitations, GNSS can be integrated with inertial navigation systems (INS), which use sensors such as accelerometers, gyroscopes, and magnetometers to measure the vehicle's motion and orientation. In this article, we will explore the main challenges and benefits of using GNSS/INS for autonomous vehicles.
