Struggling with drift in GPS-denied environments? See how combining an INS with a Laser Velocity Sensor reduced positional drift to sub-0.1% in underground tests.

GPS is arguably one of the most powerful and transformative technologies of the modern era. What happens when it stops working?

The Laser Velocity Sensor (LVS) is a new class of navigation technology developed by Advanced Navigation that uses infrared (IR) lasers to measure a vehicle’s ground-relative 3D velocity with extraordinary accuracy and precision.

With low-cost GPS jamming and spoofing technologies becoming widely available, relying solely on GPS for navigation has become an increasingly risky option for armored combat vehicles. Despite the dangers, many defense fleets around the world remain ill-equipped to navigate effectively through contested environments where GPS is compromised.

Advanced Navigation recently concluded its 2023-24 Student Grant Program. The Program is designed to motivate and financially support high-achieving engineering students with their studies and career development. This year, we asked applicants to envision an autonomous system that would improve human lives.

Maritime intelligence is required for a variety of reasons, including underwater infrastructure inspections and environmental monitoring, and its significance is only increasing.

Advanced Navigation’s light detection altimetry and velocimetry (LiDAV) system sets a new benchmark for laser-based distance/range and velocity measurement. This patent pending technology delivers a navigational sensor capable of measuring distance and velocity with extreme accuracy and with less hardware than any other system with similar characteristics.

As the use of autonomous systems continues to grow, the importance of their ease of integration cannot be overstated. This refers to how seamlessly a system can be integrated into a vehicle or platform, both physically and electronically.

Oil rigs, those formidable structures used for extracting crude oil and natural gas from beneath the ocean floor, face an intriguing dilemma when they reach the end of their productive life. In accordance with international law, governments typically require retired oil rigs be treated as maritime waste and removed. However, there is a growing interest in repurposing them as artificial reefs.

In October 2023, Advanced Navigation deployed its micro hovering autonomous underwater vehicle (AUV) Hydrus off Rottnest Island, Western Australia. The purpose of the mission was to capture high-quality still imagery and 4K video, for the purposes of benthic inspection and 3D photogrammetry reconstruction.
