This article discusses the critical aspects of easy integration that you should consider when selecting an INS.

The sections covered are: How are inertial navigation systems changing industries, INS Integration – Your way to perfect navigation, and Inertial Labs’ Solutions for INS integration. The conclusion will summarize the benefits of easy INS integration and how Inertial Labs™ facilitates this process.

Section 1. How are inertial navigation systems changing industries?

Inertial navigation systems (INS) are changing industries by providing accurate position and motion data even when traditional navigation methods such as GNSS fail or are unreliable.

Here’s how INS is transforming key industries:

• INS plays a critical role in providing precise navigation for aircraft and UAVs, especially when external navigation data is unavailable (e.g., in areas inaccessible to satellite signals). Modern drones and UAVs actively use INS for autonomous operations, significantly expanding their capabilities in various missions, from surveillance to cargo delivery [1].
• Marine navigation. INS provides reliable tracking of a vessel’s position in environments where GNSS receivers may experience signal loss (such as in polar regions or near large vessels and structures). Integrating INS with other systems helps manage the dynamic positioning of the oil and gas industry platforms, ensuring safety and accuracy [2].
• Construction and surveying. INS combined with GNSS and LiDARs allows you to create maps and models with centimeter accuracy, significantly speeding up surveying work and improving data quality. Construction equipment equipped with INS can operate with minimal human intervention, increasing efficiency and reducing errors under challenging conditions [3, 4].
• Autonomous vehicles. INS and LiDARs provide reliable vehicle positioning in environments where GNSS signals are unavailable or inaccurate, such as tunnels, urban canyons, or adverse weather conditions. In advanced driver assistance systems (ADAS), INSs improve vehicle tracking accuracy and ensure real-time safety [5].
• Defense and Security. INS provides critical navigation for unmanned systems, tanks, and missiles where GPS signals can be spoofed or jammed. INS are used for precise positioning and navigation in environments where data privacy is critical [6].
• Robotics and automation. INS and LiDAR enable robots to navigate efficiently inside buildings and underground structures where satellite signals cannot be received. INS controls robot movements in warehouses and manufacturing areas, increasing productivity [7].

Inertial navigation systems are vital to ensuring autonomy and reliability in various applications. They enable more accurate, safer, and more efficient solutions that operate even in the most challenging environments.

Section 2. INS Integration – Your way to perfect navigation.

Integrating INS with GNSS or other sensors/systems creates robust solutions that significantly improve the accuracy and reliability of navigation data. Here are the main reasons why ease of integration is critical:

• INS integration can be a complex task requiring much time and effort, even from experienced professionals. Therefore, when choosing an INS, it is essential to consider the performance, functionality, cost, and ease of integration. Easy integration reduces setup time and installation and ultimately reduces costs. Successful installation requires complete instructions and quality technical support, ensuring smooth operation and rapid system deployment.
• When integrating INS, it is crucial to consider the compatibility of the equipment. Most manufacturers use standard interfaces, such as RS-232/422, Ethernet, and CAN, simplifying integration and minimizing the need for modifications. These interfaces communicate efficiently with peripheral devices, sensors, and GNSS receivers. In solutions that require high performance, special attention is paid to the strength and reliability of the components, as well as protection from dust and water, where the IP-67 protection rating is the most preferable.
• When selecting an INS, it is essential to consider size, weight, and power requirements, as these factors can be critical when installing the system in UAVs or other aircraft/vehicles where weight and size are crucial or space is limited. Smaller, lighter systems allow UAVs to stay in the air longer due to better battery conservation. Some manufacturers offer OEM solutions with printed circuit boards and standard connectors, especially useful in applications with tight space and weight constraints.
• INS solutions are typically supplied with Software Development Kits (SDKs) for easy installation and customization. The SDKs include all necessary cables and accessories for installation and testing, and the wires can be customized to suit specific requirements.
• Most INS systems can be controlled and configured via a graphical user interface (GUI) accessible via standard web browsers or desktop applications. These interfaces provide real-time information on position, orientation, sensor data, etc. In addition, the user interfaces offer various options for customizing the INS system to meet project requirements. The more intuitive and straightforward the interface, the easier it is to configure and integrate the INS system.
• Reliable INS manufacturers understand the importance of supporting customers working closely with them to provide the necessary documentation, training, and ongoing assistance. They help select the optimal solution, ensuring compatibility with the proper hardware and software. Once a solution is selected, customers can count on detailed guides covering all stages, from setup to resolving integration issues. Ideally, manufacturers provide dedicated support engineers with in-depth product knowledge who provide technical assistance and troubleshooting through various channels, always available to respond promptly to requests.
• The integration of navigation systems requires compliance with international regulations and requirements. Companies should study the rules for their target market and ensure their navigation system complies with all requirements. It is recommended to pay attention to the following:
• ISO (International Organization for Standardization). ISO standards ensure product compatibility and safety.
• ITAR-free. ITAR (International Traffic in Arms Regulations) is a strict U.S. law requiring the exportation and transfer of military or defense-related technology and equipment. Products classified as ITAR-free are not subject to these restrictions, making it easier to export to international markets.
• Compliance and Certification. All products have regulatory compliance certifications such as MIL-STD-810. The MIL-STD-810 standard is necessary because it defines test methods that verify the resistance of equipment and materials to extreme environmental conditions. The U.S. Department of Defense developed it to ensure that military and industrial products function effectively in real-world combat and harsh operational situations.
• It is vital not to underestimate the importance of availability and fast delivery when selecting INS. Often, manufacturers and their suppliers have extended lead times. Therefore, evaluating the manufacturer’s ability to deliver products on time ensures smooth operations. Neglecting this aspect can lead to delays or cancellations of orders.

When choosing an INS solution or trading partner, carefully considering the integration and cooperation process is vital. A good vendor provides universal compatibility, complete documentation, reliable technical support, customizable settings, industry-standard compliance, and prompt delivery. These aspects play a crucial role in ensuring smooth and easy integration.

With a trusted INS provider, users can significantly simplify the integration process, eliminating the need for highly specialized knowledge or expensive technical support. This helps save time and resources and ensures sustainable operational success in the long term.
