Navy divers to have automated logging from worn dive computers

By Bobby Cummings, Office of Naval Research,

ARLINGTON, Virginia (NNS) -- For U.S. Navy deep-sea divers, time is of the essence. While operating 100 feet down, with little to no natural light—often in frigid temperatures and limited oxygen—time is everything.

But for divers, time remains a precious commodity on the surface as well.

For years, military divers have had to manually write and log information from dives while at sea into a system known as the Dive/Jump Reporting System (DJRS). Manual entries can be time-consuming and allow human error.

Enter the Office of Naval Research (ONR) Global TechSolutions program, a rapid-response science and technology program focused on solutions to problems submitted by Sailors and Marines.

ONR TechSolutions and industry partners have created a new tool called the Scuba Binary Dive Application (SBDA) 100 to digitally plan, record and report dive-profile information to DJRS. The application will accelerate the process of logging and uploading dive information, and will help eliminate potential data-entry mistakes.

The idea originated from Force Master Diver Scott Brodeur, Naval Expeditionary Combat Command.

“Scott has completed over a thousand dives during his career and he recognized the need to make the logging and reporting process more efficient for his peers,” said Jason Payne, TechSolutions acting program manager.

The SBDA 100 is a software application on a ruggedized tablet used to log, compute and accurately compile dive-profile data.

The data, collected from a wrist watch that divers wear during operations called a Navy Diver Computer, includes dive site conditions, equipment used by the divers, dive events, such as, when a diver left the surface or left the bottom of the ocean floor, and if the dive required decompression stops. SBDA 100 syncs this information and automatically uploads it to DJRS.

“For years, I witnessed how many hours it takes to manually log dives—watching the young guys that have to—at the end of a long 12 to 14-hour-day—come back and manually go through the dive logs and write everything down, and double check it and triple check it,” said Brodeur.

During a recent training exercise in the Gulf of Mexico, Brodeur, the Naval Experimental Dive Unit and other U.S. Navy divers stationed around the globe had the opportunity to test the technology for the first time.

“The designers gave me a crash course on how to operate the technology,” said Chief Navy Diver Marshall Goble, ship repair facility, Yokosuka, Japan. “I used the device as a primary but still used the ‘old school' way and wrote down the information as well. Both calculations came out 100 percent accurate. I found the tablet easier to use, and I have no doubt it's going to streamline efficiency.”

Throughout the process of the development of the SBDA 100, ONR TechSolutions has worked in conjunction with Space and Naval Warfare Systems Command (SPAWAR) Atlantic; industry partner Intelligent Automation Inc.; and Naval Surface Warfare Center (NSWC) Panama City, which is the home of the U.S. Naval Diving and Salvage Training Center. SPAWAR served as the principal investigator and NSWC Panama City provided technical support and hosted the training and demonstration of the SBDA 100 at sea.

“The technology has tested very well,” Brodeur said. “It's a testament to the value of the ONR TechSolutions program and everyone who worked on this project. Witnessing this idea come to fruition and have it be built, demonstrated, designed and ready for use is pretty exciting.”

Boeing ends deal, angering Brazilian jet maker Embraer
By: The Associated Press CHICAGO — Boeing announced Saturday it terminated an agreement to join forces with Embraer, prompting an angry response from the Brazilian jet maker, which threatened to seek damages. The pair had planned to work together on Embraer's commercial aviation business and to develop new markets for its C-390 Millennium aircraft. They had been working toward an agreement for two years. Boeing said it ended the agreement after Embraer did not meet conditions laid out by the deal, in which Boeing would have held majority ownership. Over the past few months, the companies had “productive but ultimately unsuccessful negotiations” about the unsatisfied conditions, which was “deeply disappointing,” Marc Allen, Boeing's president of Embraer partnership and group operations, said in a news release. Embraer issued a statement saying it “believes strongly that Boeing has wrongfully terminated” the mutual transaction agreement and “that it has manufactured false claims as a pretext to seek to avoid its commitments to close the transaction and pay Embraer the US$4.2 billion purchase price.” “We believe Boeing has engaged in a systematic pattern of delay and repeated violations of the MTA (master transaction agreement), because of its unwillingness to complete the transaction in light of its own financial condition and 737 Max and other business and reputational problems,” it added. “Embraer will pursue all remedies against Boeing for the damages incurred by Embraer as a result of Boeing's wrongful termination and violation of the MTA,” the company said. The collapse marked the latest mishap for Boeing. The company's best-selling plane, the 737 Max, has been grounded for more than a year after two deadly crashes that led to federal investigations. Those problems, combined with deflated demand for flights due to the pandemic, sharply reduced the company's cash. https://www.defensenews.com/air/2020/04/26/boeing-ends-deal-angering-brazilian-jet-maker-embraer/

Navy inks deal for synthetic aperture radar imagery
Nathan Strout Capella Space announced May 13 that it signed a deal to provide synthetic aperture radar to the U.S. Navy, even though the company has yet to put a satellite on orbit. Unlike traditional electro-optical satellite imagery, which can be degraded or denied by adverse lighting conditions or weather, SAR creates images with radar, meaning it can produce images regardless of the weather or lighting conditions. Additionally, SAR sensors can provide data on material properties, moisture content, precise movements, and elevation, meaning that SAR can be used to build 3D recreations of a given geographical area. Capella says its planned SAR satellite constellation will be able to collect sub-0.5 meter imagery, capable of identifying various types of aircraft or vehicles at ground level. Still, the company has yet to put a single payload of their planned 36 satellite constellation on orbit. Although Capella executive hoped to have satellites launched by the end of 2019, it noted in January that the first satellite wouldn't launch until March, with six more to follow by the end of the year. With this latest announcement, the company simply stated the first launch would take place later this year. Until then it will collect imagery by flying its synthetic radar on a specially outfitted airplane. The Navy signed a contract with the company through the Defense Innovation Unit's Commercial Solutions Opening. Under the new contract, Capella will provide imagery as well as in-house analytics for interpreting that data. The Navy deal is just the latest military and intelligence contract for the company. “Defense & intelligence agencies utilize Capella's SAR data for a variety of purposes, including disaster recovery, infrastructure monitoring and indications and warnings of potential threats,” said Capella CEO and Founder Payam Banazadeh. “The continuous work we receive from these agencies is a testament to the future they see where Capella services play an important role in our national security.” The Air Force awarded the company a contract in November to use its SAR for virtual reality software, missile defense and developing predictive intelligence to foresee foreign threats. On the intelligence side, the National Reconnaissance Office issued a commercial study contract to the company in December as part of its efforts to diversify what types of imagery the agency purchases from commercial companies. https://www.c4isrnet.com/space/2020/05/13/navy-inks-deal-for-synthetic-aperture-radar-imagery/
