Important results from the project
The goal of investigating the transfer of civil technology for magnetic field navigation to military technology solutions for navigation of underwater platforms was achieved. Important results are: 1) New quantum sensors theoretically provide the same performance as an export classified DVL, but without emitting a signal. 2) Performance is limited by self-interference and natural field variations. Research is required to develop strategies to handle time variations and self-interference.
Expected long term effects
The developed technology supports covert long-term navigation below the surface and thereby enable transfer of the tactical advantages seen in airborne drones to autonomous marine systems. The technology strengthens Sweden´s strategic capability, contributes to robust navigation in the event of GPS jamming. The project initiates a new branch within the national research center SMaRC, establishes international cooperation and creates new business opportunities for participating industry.
Approach and implementation
The cooperation with all parties has continued well and monthly online meetings have been held. Two workshops were held, which has meant that all project parties have had the opportunity to jointly delve into the results and the execution. The start was delayed due to security challenges. Furthermore, the sensors that the project used were export classified, which made the procurement process difficult to manage in a 1-year project. All planned activities have been implemented.
