IGNS Product

IGNS

IMU and GNSS System

The IGNS is a robust Inertial Measurement Unit (IMU) that is integrated with a GNSS receiver.

The modular architecture of the IGNS provides one inertial system with three different performance grades accompanied with a GNSS receiver that supports several types of constellations: GPS/GLONASS/Galileo/BeiDou/NaviC/QZSS.

The IGNS’s flexibility, delivers the accuracy and price to precisely meet your application requirements.

The IGNS employs the latest closed-loop Fiber Optic Gyro (FOG) technology, providing fast, high precision, autonomous navigation. Cielo’s IGNS system is ITAR-free and meets military standards (MIL-STD 810, MIL-STD 461, MIL-STD 1275. It has high MTBF (>20,000 hr.) and requires no periodic maintenance. The IGNS can be used for control and stabilization for various applications at land, air and sea environments.

Compatible for the following applications:
MALE UAV
Fixed and rotary wing UAV's
Armored vehicles
Command vehicles and tanks
Missiles
Air-to-surface missiles
