Inertial navigation systems are an important part of modern military operations for improving accuracy and reducing life tolls. If you are looking to purchase an inertial navigation system, several factors can help you decide on the best one for your application.
The following are major factors that need to be considered when choosing INS.
Size of Areas to Be Mapped
The first major factor to consider when choosing INS is the size of the area that needs to be mapped. A global navigation satellite system (GNSS) can map an entire planet. However, it has relatively low accuracy for more specific areas. On the other hand, INS can provide high accuracy in specific areas but cannot map an entire planet. The INS must download maps of the area it is traveling in before entering that area. If no map exists, INS will struggle to navigate until one is downloaded.
The Size of the System
The size of the inertial navigation systems is very important. The size of the inertial navigation system can help you determine where to place it in your vehicle, as well as how much room you have for other electronic components. If the system is too large, the installation will be difficult and time-consuming. It can also become a safety hazard as it cannot be properly secured in larger vehicles.
The drift properties will depend largely on the quality of the inertial navigation system you purchase. Inertial navigation systems are designed to have no drift or very low levels of drift. This means that the sensors must be calibrated every time they are turned on.
Inertial navigation systems (INS) use sensors to track changes in direction and speed. This allows them to measure the current position without being given any information from outside sources. The ability has made INS a crucial part of modern military operations for improving accuracy and reducing life tolls.
