ARLINGTON, Va. – U.S. Navy researchers have cleared Logos Technologies LLC in Fairfax, Va., to continue development of the Spectral and Reconnaissance Imaging for Tactical Exploitation (SPRITE) wide-area motion imagery (WAMI) sensor pod.

Officials of the Office of Naval Research (ONR) in Arlington, Va., say Logos has met all the goals of its five-year contract with ONR for the SPRITE system.

ONR experts supervised a test flight of the a U.S. military version of the company’s platform-agnostic Multi-Modal Sensor senor pod (MMSP) aboard a manned Cessna 337 Super Skymaster general aviation aircraft.

The Logos MMSP houses WAMI, hyperspectral, and inspection sensors, and processes the data onboard manned or unmanned aircraft in real time.

The MMSP persistent-surveillance sensor pod can cover an area the size of a city; offers cross-sensor cueing; can stream video on as many as 10 windows, depending on datalink bandwidth; and offers user-defined watchboxes and alerts; offers multiplexed motion videos for several user-defined locations; provides transmission to mobile devices over an internal datalink; and archives data every four to eight hours.

"We had SPRITE flying between four and five hours a day for a whole week,” says Chris Stellman, lead principal scientist and program manager for Logos Technologies. “We were able to use SPRITE’s sensor modalities to detect signatures of interest, process that data on the fly, and stream it down in real time to users on the ground."

The SPRITE senor pod houses an ultra-light Logos Technologies RedKite WAMI sensor, a high-definition spotter camera, and commercial shortwave infrared hyperspectral sensor.

In addition, SPRITE contained a Logos palm-sized multi-modal edge processor (MMEP) to process the raw data being produced by all three sensors, in real time, and cross cue between the sensors.

The MMEP is the brains of the SPRITE senor pod,” Stellman says. “It’s what makes data actionable to the warfighter and searchable to the analyst."
