Global Navigation Satellite System (GNSS) and Inertial Navigation System (INS) technology is employed by autonomous surface vessels (ASV) to facilitate the completion of critical missions by naval for

Septentrio is a leading global supplier of high-precision positioning technology, specialising in multi-frequency, multi-constellation GNSS receivers for demanding applications. These receivers combine advanced GNSS technology with Inertial Navigation Systems (INS) to provide accurate and reliable positioning and navigation solutions.Designed to meet the most demanding industrial and military needs, Septentrio's GNSS/INS receivers provide continuous, accurate positioning information in a wide range of environments and maintain performance even when the GNSS signals are interfered with or obscured. and maintain performance even when GNSS signals are interfered with or obscured.

Septentrio's GNSS/INS receivers incorporate several advanced technologies, including:

1. **AIM+ Advanced Interference Mitigation Technology**: This technology protects the receiver from a wide range of interference and spoofing attacks, ensuring the accuracy and reliability of navigation in contested environments.

2. **FUSE+ technology**: this is an advanced sensor fusion technology that combines GNSS and INS data to provide high-precision 3D positioning information, including heading, pitch and roll angle. This technology is particularly suitable for use in environments where GNSS signals are obscured or interfered with, such as urban canyons, indoors or in dense forests.

3. **Multi-frequency, multi-constellation capability**: The receiver is capable of tracking multiple GNSS constellations (e.g. GPS, GLONASS, Galileo, BeiDou, etc.), as well as multiple frequency signals simultaneously, thus providing optimal signal availability and immunity to interference in complex signal environments.

4. **Ruggedised design**: Septentrio's receivers are designed for use in harsh industrial and military environments and are water, dust and shock resistant.

Saronic Technologies chose Septentrio's GNSS/INS receivers because of their high performance and reliability to meet the stringent requirements of its ASVs for precise navigation in the performance of their missions. This partnership enables Saronic's ASVs to maintain operational effectiveness in complex maritime environments, whether they are on missions in the open ocean or in near-shore waters.

With Septentrio's technical support, Saronic's ASVs are able to increase their utility in modern naval operations, providing critical intelligence, surveillance and reconnaissance capabilities to the maritime fleet, while ensuring navigational accuracy and mission success in the face of potential threats. This technology partnership was one of the key factors in securing Saronic's investment in the Series B round of funding and is a key driver of its success in the defence technology sector.
