Inertial Navigation Systems and Stabilised Platforms: An Overview
When it comes to navigation, inertial navigation systems (INS) and stabilised platforms are two key components. These systems are used in many industries, including aerospace, shipping, military, and more. But what exactly is an inertial navigation system? What about a stabilised platform? In this blog post, we’ll explore the answers to these questions and more.
What is an Inertial Navigation System (INS)?
An inertial navigation system (INS) is a subsystem of a vehicle that uses sensors to measure acceleration and angular velocity in order to calculate the position of the vehicle relative to its starting point. INS utilizes dead reckoning as its primary method of navigation; this means that no external references or landmarks are required for calculation. Instead, the INS relies on precise measurements from accelerometers, gyroscopes, and other sensing devices in order to determine its position.
Because INS does not require external references or landmarks for calculations, it can be used in environments where conventional navigational methods—such as GPS—cannot be used effectively due to interference or lack of satellite coverage. Additionally, since there is no need for periodic updates from an external source—such as a GPS signal—the INS can be used for extended periods of time without interruption or degradation of accuracy.
What is a Stabilised Platform?
A stabilised platform is essentially an advanced form of a gimbal-mounted platform that can maintain its orientation relative to some reference frame—typically the horizon or ground plane—despite environmental disturbances such as wind gusts or uneven terrain. This type of platform utilizes sophisticated servo systems and gyroscopic sensors in order to constantly adjust itself so that it remains oriented in the same direction despite external disturbances. Stabilised platforms are commonly found on aircraft and ships; they provide superior stability when compared with unassisted gimbal-mounted mounts while also providing improved precision over traditional gyroscopic-based stabilization systems.
Inertial navigation systems and stabilised platforms are two key components of any navigational system. INS provides accurate positioning without requiring any external references or landmarks; meanwhile, stabilised platforms provide superior stability despite environmental disturbances such as wind gusts or uneven terrain. Together, these two technologies provide reliable navigational solutions for many industries including aerospace, shipping, military applications and more. Understanding how these systems work can help you make informed decisions about your own navigational requirements.
