NRL has a broad portfolio of technologies and over 1300 active patents or patent applications that are available for license. Below is a list of links to more information for a number of NRL technologies that have potential commercial applications.

The US Navy has developed and tested BOPPERS for the repeated unattended collection and reporting of environmental data from the entire water column from depths of 100m or less. BOPPERS: Autonomous Underwater Environmental Monitoring System

NRL has developed a shallow water environmental profiler the autonomously measures physical and optical properties of the water column at periodic, user-specified intervals over an extended time period (weeks to months). Data are collected and stored on-board, and can be transmitted in near-real-time to a land station when the profiler surfaces. The patent-pending NRL system, equipped with advanced instrumentation, includes the capability to simultaneously collect measurements of physical and bio-optical properties.

The US Naval Research Laboratory detachment at Stennis Space Center has developed GRIN, a fast, flexible, and highly efficient means of compressing geospatial datasets by thinning points while maintaining a high degree of accuracy for the remaining data points. GRIN is a new algorithm for calculating Right Triangulated Irregular Networks (RTINs) that preserves the positional integrity of the remaining original grid points. GRIN is designed for charting, navigation, and other high-precision applications.

Intrusion Detection

NRL researchers have developed an intrusion detection system for undersea pipelines that detect intruding objects as well as leakage effects from the pipelines.

Mobile Underwater Acoustic Communications

NRL researchers have developed a method for mobile underwater acoustic communications that encodes a communication signal for transmitting a doubly differential (DD) spread spectrum (SS) communication output signal. The doubly differential spread spectrum (DD-SS) method results in a highly reliable and efficient system for long range acoustic communications (LRAC).
