SBG Systems

SBG Systems is a French developer and manufacturer of MEMS-based and ITAR-free inertial navigation solutions for mission-critical defense and tactical applications. The company provides a complete line of inertial sensors, including AHRS, IMU and embedded INS/GPS solutions, combining advanced calibration techniques with embedded algorithms to deliver excellent performance in challenging and contested environments.

SBG products have been deployed in the air, on land and at sea, providing high-accuracy inertial measurement data for a wide range of use cases, including GPS-denied navigation, control, antenna tracking, camera and platform stabilization, and more.

Precision Pointing, Stabilization & Tracking

SBG Systems’ inertial sensors support stabilization, pointing and tracking systems, enabling payloads, instruments and defense platforms to maintain alignment with satellites, antennas, and targets. The company’s solutions are designed for low-noise accelerometer and gyroscope measurements, with synchronized measurements between axes and low latency between physical motion and output.

These capabilities are essential for defense applications requiring precise alignment and motion compensation in the face of high levels of movement and vibration. SBG Systems’ sensors can be incorporated into a wide range of platforms, from low-dynamic marine vessels to high-dynamic military drones, supporting steady sensor orientation and more reliable imaging, data collection and navigation outputs.

The company’s inertial solutions are also ideal for antenna stabilization, target designation, target tracking and turret pointing. By providing reliable pointing information from sources such as magnetometers or GNSS compass data, they enable electro-optical systems to support surveillance, target acquisition and automatic tracking in both static and dynamic conditions.

Precision-Guided Munitions

SBG Systems provides tactical and industrial-grade IMU solutions for guided munitions, delivering robust motion data for ammunition control and navigation. The company’s IMUs integrate MEMS sensors and filtering algorithms to support guidance, navigation and control for short- to medium-range ammunition and decoys, with compact form factors and simplified integration.

The sensors are designed to withstand shocks, vibrations and temperature variations, making them suited to the demanding conditions experienced by precision-guided munitions. Multi-axis gyroscopes and accelerometers provide angular rate and linear acceleration data, supporting real-time navigation and control.

SBG Systems’ IMUs combine MEMS technology, multi-axis sensing, efficient filtering and synchronization to deliver accurate real-time data for guidance systems. Shock-hardened construction, thermal compensation and rapid data updates allow the sensors to support critical flight phases while maintaining performance in harsh and varying environments.

Tactical UAV Navigation

SBG Systems’ inertial navigation solutions support defense and tactical UAVs operating in environments affected by electronic warfare, GNSS interference, jamming and spoofing. The company’s inertial sensors provide an alternative or complementary source of positioning, navigation and timing data, helping defense platforms maintain operational capability when traditional PNT systems are compromised.

Inertial systems can act as both primary and secondary navigation aids for unmanned aircraft, working alongside GNSS, magnetometers, air data and other aiding sensors. By providing continuous real-time navigation data, these systems support collision avoidance, path planning, situational awareness and increased autonomy for unmanned platforms.

SBG Systems’ UAV solutions are based on MEMS inertial technology and are available in rugged and compact OEM form factors. Rigorously tested to MIL-STD 810 standards, the systems are built to endure shocks, vibrations, temperature variations and harsh climates, while also offering flexible integration through APIs and compatibility with popular autopilot systems.

Loitering Munitions

SBG Systems’ inertial navigation solutions are highly suited to loitering munitions that require precision guidance, enhanced stability and reliable operation during complex missions. These systems provide accurate data on position, velocity and orientation, supporting precise navigation, targeting and control throughout the mission profile.

The company’s MEMS-based INS and IMU solutions are designed to address the environmental challenges and constraints associated with loitering ammunition. With low noise, bias and latency, they are ideal for navigation as well as real-time control, with low SWaP profiles that enable them to be integrated into a range of designs.

SBG Systems’ navigation algorithms allow inertial systems to model IMU errors using a position reference such as GNSS, enabling dead reckoning after GNSS loss during a mission. The systems are also compatible with a variety of aiding sources, and are designed to operate in a range of harsh conditions including electronic countermeasures, severe weather and high-speed maneuvers.

UGV Navigation

SBG Systems’ inertial navigation solutions equip unmanned ground vehicles operating in complex, hazardous and GNSS-challenged environments with precision navigation capabilities, supporting a wide range of missions including mobility, surveillance, acquisition, reconnaissance and armament.

For UGVs operating in urban canyons, tunnels or contested battlefields, SBG Systems’ products provide navigation continuity when GNSS signals are unavailable, unreliable or intentionally jammed. This allows vehicles to maintain situational awareness and autonomy without relying on external references such as GNSS or communications links.

The company’s inertial navigation systems also provide real-time data on vehicle position, velocity and orientation, supporting precise control across rugged terrain and off-road conditions. They can be integrated with onboard sensors such as cameras, LiDAR and odometry to form multi-sensor navigation systems, improving localization accuracy and situational awareness in dynamic environments.

USV Navigation

SBG Systems’ inertial sensors have been integrated into uncrewed surface vehicle platforms used for ISR missions, as well as other maritime operations requiring reliable navigation and real-time data collection. These cutting-edge sensors enable autonomous and remote-controlled vessels to operate accurately and efficiently across complex naval and littoral environments.

The company’s motion and navigation systems feed USV decision-making processes, enabling vessels to follow predefined routes, avoid obstacles and respond to changing conditions. They also support remote operation by transmitting real-time navigation data, sensor readings and video to control stations, allowing operators to intervene during critical situations.

SBG Systems’ solutions can also utilize sophisticated sensor fusion to integrate data from multiple sensors, including GNSS, IMUs and sonar, to improve positioning accuracy and reliability.
