Land Navigation Suite

Aeron's Hybrid Land Navigation System (HLNS) is a high-performance navigation solution designed to operate in challenging environments. The inertial navigation system (INS) is equipped with a high-end tactical grade Inertial Measurement Unit (IMU) which ensures the accurate navigation information even in GNSS denied conditions. This makes HLNS, an ideal choice for military vehicles enhancing their operational efficiency and providing uninterrupted navigation information in varying terrains that include mountains, deserts, and densely-forested regions.

The combat vehicle users require reliable and resilient navigation in all operating scenarios. They are dependent on the navigation data, that is, latitude, longitude, altitude and heading on a continuous basis to take tactical decisions. Armoured vehicles both wheeled and tracked need this information without having to depend on external factors such as GNSS which may be jammed or spoofed. Aeron's field-proven, reliable, and rugged navigation systems assure consistency in delivering accurate position information even in long hours of GNSS outages.

The navigation solution is available in multiple configurations to meet the needs of diverse users. The Octantis INS system is based on tactical MEMS IMU offering excellent GNSS denied performance, the Aldebaran INS based on closed loop Fiber-Optic Gyros (FOG) delivers superior GNSS denied performance. The systems are qualified as per the MIL-STD-461E or F, MIL-STD-81OG, and MIL-STD-1275E for electromagnetic compatibility (EMC), environmental and power supply survivability respectively. The system integrates seamlessly with Aeron's navigation software.

HLNS is thus an ideal system for providing position and navigation information, making it an integral part of both the battlefield management and situational awareness systems. Aeron's HLNS solution comes with a capable navigation software that provides offline and online maps capability, mission data recording, way points and capability to import military maps. Aeron provides MIL COTS display with the software or the software can be deployed on existing or user-recommended display.
