Anello Photonics has been awarded a contract by the US Navy to develop a cutting-edge navigation system for hypersonic vehicles that can operate even in GPS-denied environments.
Anello Photonics, a leading company in silicon photonics technology, has secured a contract from the US Navy to develop a cutting-edge navigation system for hypersonic vehicles, designed to function even in GPS-denied environments. Anello was chosen for a Small Business Innovation Research Phase I grant due to its innovative optical gyroscope technology and its unique sensor fusion engine, the company announced.
The company's Silicon Photonics Optical Gyroscope (SiPhOG) technology and sensor fusion engine are poised to revolutionize navigation. 'This will ensure that the US Navy platforms can maintain high-accuracy navigation in challenging GPS-denied situations,' stated the company.Overcoming GPS reliance is a key aspect of this development. SiPhOG is a compact, ultra-lightweight, and high-performance optical gyroscope that promises accurate guidance even when Global Positioning System (GPS) signals are unavailable or compromised. Traditional navigation systems often heavily depend on GPS, but in contested environments where hypersonic vehicles operate, GPS signals can be easily disrupted or denied by adversaries. Anello's SiPhOG technology offers a distinct approach to navigation in GPS-denied situations.Typically, a loss of GPS signal triggers a failsafe mode in the autopilot system, potentially leading to undesirable outcomes such as hovering in place, an emergency landing, or even a crash. However, with Anello's SiPhOG technology, demonstrated in their recently launched Anello X3, the system can seamlessly detect GPS signal disruption. Instead of resorting to a failsafe mode, the SiPhOG gyroscope provides continuous and accurate navigation data, allowing the vehicle to maintain controlled flight even in the presence of GPS jamming. The technology leverages the principles of interferometry to precisely measure a vehicle's rotation and orientation. Within the SiPhOG, laser light travels through a microscopic waveguide etched onto a silicon chip. This chip also houses integrated optical components that manipulate the light, creating interference patterns. By analyzing these patterns, the SiPhOG can determine the vehicle's precise movements with exceptional accuracy.Under the recent contract, the company will focus on demonstrating the capabilities of SiPhOG and the sensor fusion engine over a six-month period. If successful, the project will progress to Phase II, which will involve developing a prototype navigation system and rigorous testing in simulated hypersonic flight conditions. Phase III aims to integrate the prototype onto a representative hypersonic vehicle for demonstration and assessment during Advanced Naval Technology Exercise (ANTX) events. Developmental efforts for GPS-free navigation are gaining momentum amidst increasing geopolitical tensions and the use of advanced warfare technologies. The US Navy's latest award to Anello Photonics reflects this broader trend. 'Within this program, the U.S. Navy can directly evaluate and experience first-hand the benefits of the Anello products for navigation in GPS-denied or contested environments,' concluded Dr. Mario Paniccia, CEO of Anello Photonics. Notably, several studies have been conducted in this regard. Recently, the Sandia National Laboratories of the US developed 'the mother of all motion sensors', aiming to enable GPS-free navigation for air defense vehicles. Additionally, Sydney-based Advanced Navigation has partnered with MBDA to develop a system that will allow drones to fly high in the sky and navigate without GPS
