GNC

Guidance, navigation and control systems (HW + SW)

Comprehensive GNC system to control any weapon system

In addition to our semi-active laser guidance kit, AERTEC designs and develops guidance, navigation and control (GNC) systems that can control any guided weapon. These systems interpret signals from the seeker and onboard sensors, process the information in real time and send control commands to actuators to accurately guide the munition towards the target.

We are seeker and platform agnostic: we design, manufacture and integrate GNC systems for missiles, micro-missiles, glide bombs, guidance kits and loitering ammunition.

Capabilities and technical features

We supply:

Full GNC system (hardware + firmware + software) or subsystems (flight computer, guidance libraries, controllers, actuator drivers).

Architecture:

Modular and open for quick integration into existing avionics.

Turnkey process:

Systems engineering, development, V&V (SIL/HIL), client integration, test support and knowledge transfer.

Seeker/sensor compatibility:

SAL (semi-active laser), IIR/TV, MMW radar, RF and multi-sensor configurations.

Supported sensors:

IMU/INS, GNSS, magnetometers, altimeter, GNSS degraded/denied.

Guidance (G):

Guidance laws, 3D trajectory planning and tracking, mission profiles, terrain/threat avoidance, terminal homing.

Navigation (N):

Advanced sensor fusion (Kalman filters), in-mission alignment/calibration, resilient PNT and dead reckoning.

Control (C):

Robust and adaptive controllers, electromechanical actuator management, auto-trim/auto-tune, saturation limits and management.

HW/SW:

DO-178C / DO-254 certifiable design; embedded flight computer with deterministic processing and low latency; BIT / FDIR and mission logs.

APIs and libraries:

Reusable libraries, APIs for rapid integration and development of real-time status assessment software.

V&V and simulation:

6DoF simulations with sensor, actuator and environment models; bench and in-flight test support; documents and testing in accordance with applicable MIL-STD.

Applications:

Micro-missiles, AS/SS tactical missiles, glide bombs, guidance kits, loitering munition, stabilised pods.

Comprehensive development:

Design → Development → Manufacturing → Integration → Testing → Support.

How it works — operational flow and phases

AERTEC's GNC systems operate on a sensing and control closed loop that is optimised for real-life missions:

This sequence ensures optimal performance in all kinds of tactical scenarios.
