AUVSI XPONENTIAL 2016, NEW ORLEANS, 4 May 2016. Curtiss-Wright’s Defense Solutions division is introducing the Data Transport System 1-Slot (DTS1) to address the rapidly increasing demand for high-capacity, secure storage on unmanned aircraft systems (UAS) and intelligence, surveillance, reconnaissance (ISR) aircraft.

The small-form-factor data transport system for storing large amounts of data on deployed unmanned vehicles and ISR platforms – a single-slot Network Attached Storage (NAS) device weighing 4 pounds and measuring 1.5 x 5.0 x 6.5 inches (38.1 x 127 x 165.1 mm) – delivers up to 2 TB of storage and supports advanced encryption to protect critical data-at-rest.

The DTS1, which functions as a NAS file server, helps system designers reduce size, weight, and power (SWaP) by eliminating the need for independent storage in each of the platform’s computer, display, or management devices. It enables any network-enabled device to communicate with any other similar device, to retrieve stored data or save new captured data. Networked devices using heterogeneous operating systems (Linux, VxWorks, Windows, etc.) or CPUs that support industry-standard protocols (i.e., NFS, CIFS, FTP, or HTTP) can share and store data through the DTS1.

The DTS1 is well suited for rugged applications that require the storage, removal, and transport of critical data, such as cockpit data (mission, map, maintenance), ISR (camera, I&Q, sensors), mobile (ground radar, ground mobile, airborne ISR pods), heavy industrial (steel, refinery), and video/audio data collection (flight test instrumentation) applications.

“Our new data transport system delivers a lightweight, compact solution for adding Terabytes of secure, networked data to SWaP-constrained unmanned platforms,” says Lynn Bamford, senior vice president and general manager, Defense Solutions division. “It combines the cost-effectiveness of commercial off-the-shelf (COTS) hardware with high levels of ruggedization and support for FIPS validated encryption, all in a compact four-pound package.”

The lightweight, low-power DTS1 is easily integrated into network-centric systems,

providing a turnkey, rugged NFS that houses one Removable Memory Cartridge (RMC) that provides quick off load of data. The RMC can be easily removed from one DTS1 and installed into any other DTS1 providing seamless full data transfer between one or more networks in separate locations. It also supports a packet capture software (PCAP) option, an Ethernet recording capability that allows DTS1 users to record all Ethernet packets flowing over a platform’s LAN during the course of a mission, enabling the system to record network traffic for later analysis.

An optional DTS crypto module supports applications that require secure data-at-rest. To ensure the security of critical data, all data is passed through the FIPS 140-2 certified in-line media encryptors prior to being read from or written to the RMC. The standard DTS1 encryption module incorporates AES-256 bit cryptographic algorithm and hardware that are NIST validated to FIPS 140-2. The encryption key can be passed to the encryption module by an outside agency, or special key management concepts can be developed depending on the application. The modular encryption capability also supports options for no encryption if the data is not sensitive.

Unlike competing systems that use proprietary memory devices, Curtiss-Wright data transport systems (DTSx) use commercial off-the-shelf 2.5-inch SATA solid-state drives with storage capacities ranging from 128 GB to 2 TB. With a wide variety of SSDs, the DTS memory can be scaled to meet the application needs. Each disk consumes 2 watts of power and weighs only 0.7 lb (317 g). An RMC is small enough to fit in a shirt or flight-suit pocket and yet rugged enough for transport. Error correction, wear-leveling, and bad block management are performed to ensure data integrity.
