DARPA Seeks New Inertial-Atomic Sensor to Enable Military Missions in GPS-Denied Areas

The Defense Advanced Research Projects Agency (DARPA) has launched a search for an atomic inertial sensor to measure orientation in GPS-denied environments.

The Chip-Scale Combinatorial Atomic Navigator (C-SCAN) initiative seeks to create a sensor that integrates small size, low power consumption, high resolution of motion detection, and a fast startup time into a single package.

We certainly hope the competitors in DARPA’s Robotics Challenge hardwire Isaac Asimov’s First Law of Robotics into their creations—the one that says don’t harm humans.

Because the U.S. Defense Advanced Research Projects Agency’s new contest aims to develop technology that advances robotics to the next level. The level at which robots can do what we do, go where we can’t, and change shape as necessary.

GPS Program Budget: A Lot, But Is It Enough?

The details of President Obama’s 2013 budget have been gradually filtering out and, in general, the GPS system and those programs closely linked to satellite navigation, have escaped deep cuts.

On the hardware side the White House has requested $58.2 for GPS IIF satellite procurement. According to Air Force budget documents, the plan is to then wrap up the total IIF procurement of 12 satellites with a request for $77.6 million in FY14 and $7.3 million in FY15.

DoD Strategic Guidance “Protects” GPS Modernization

GPS and other space systems fare well in the Department of Defense (DoD) strategic budget initiative outlined today (January 26, 2012) by U.S. civil and military officials.

The comments reflected policy decisions laid out in “Defense Budget Priorities and Choices,” an introduction to a strategic guidance intended to plot the course of the Pentagon over the next five years. Modernization of the Global Positioning System will be “protected” financially, according to the document.
