DSIAC collects and publishes articles related to our technical focus areas on the web to share with the DoD community.

OCTOBER IS CYBERSECURITY AWARENESS MONTH

Cybersecurity is crucial to protecting our nation’s information infrastructure. October is dedicated to increasing public awareness of the importance of cybersecurity and its role in preventing and eliminating threats to our communities and U.S. national security systems.

Our sister IAC, the Cybersecurity & Information Systems Information Analysis Center (CSIAC), brings you the most current resources to help maximize knowledge and stay cyber safe.

What are good methodologies for measuring the resilience of global navigation satellite systems?

This inquiry summarizes test and measurement methods and equipment to characterize the resiliency of various global navigation satellite systems, including the Global Positioning System (GPS) coarse acquisition code; P(Y) code; Selective Availability Antispoofing Module; GPS Block III M-code; and Link 16 multimodal position, navigation, and timing systems. In addition, basic working principles; spectral alignment; and…

Who are subject matter experts in the areas of energetic material chemistry, propellant formulations, and diagnostics?

What current research and/or commercial-off-the-shelf/government-off-the-shelf technology is available for maritime intelligence, surveillance, and reconnaissance detection?

Who are subject matter experts in the areas of shock physics, optical diagnostics, and propellant chemistry?

Is there a passive radio frequency detector that has (1) detection capabilities at 2–6 GHz at 3 km, (2) detection of brushless drone motors, (3) artificial intelligence/machine learning filtering, (4) a 10-bit digital-to-analog converter, and (5) cooling?

How is the U.S. Department of Defense addressing airworthiness concerns for small unmanned aircraft systems?

What does ERD95 refer to when related to laser designators?

Can information be provided on design tolerances for an M42 dual-purpose improved conventional munition shaped charge?

What unclassified datasets train artificial intelligence models to detect military objects from small unmanned aerial system imagery?

The Defense Systems Information Analysis Center (DSIAC) is seeking information on datasets containing military objects to train artificial intelligence models in their detection capabilities. In particular, the datasets would ideally contain multiple views of these objects that vary in range, angle, lighting, atmospheric conditions, and location. Standard electro-optical images (daytime RGB color images) with a…

A Brighter Future for the Jupiter Laser Facility

Since the 1970s, the Janus laser, now part of the Jupiter Laser Facility (JLF), has served as an experimental proving ground to Lawrence Livermore National Laboratory’s (LLNL) laser and fusion programs and the broader high-energy-density and laser science communities. Today, JLF is not only home to Janus — one of the world’s few hands-on laser…

Gaps Between Civilian and U.S. Department of Defense for Determining Airworthiness of Additively Manufactured Parts

The U.S. Department of Defense (DoD) has made some progress certifying additive manufacturing (AM) parts for airworthiness, but certification has been limited to the lab, with significant engineering and inspections required for each part. Over the last two decades, each branch of the DoD developed their own processes for AM certification, thus fragmenting certification and slowing the widespread acceptance of AM. The Federal Aviation Administration…
