DAWN PATROL Soldiers with the 2nd Armored Brigade Combat Team, 1st Armored Division (2-1 ABCT) conduct early morning operations in the training village of Khuribad, during the Network Integration Evalu- ation 16.2, at Fort Bliss, Texas, in May. New PNT capabilities are needed to equip Soldiers to safely navigate and communicate in any environment. (U.S. Army photo by Sgt. Aura E. Sklenicka, 2-1 ABCT Public Affairs)


To stay responsive to evolving threats, there is an open architec- ture requirement within the A-PNT SoS concept. As Congress has noted in acquisition reform proposals, open architecture systems provide more flexibility and potential cost savings than closed systems. Open architecture supports forward compat- ibility that will provide the ability to adapt to emerging needs and disruptive technology improvements with a “plug and play” capability. For instance, rather than conducting a complete rede- sign of a device when changes need to be made, which would be required on a legacy GPS receiver, with A-PNT, a new chip card could be inserted into a client system, thus instantly increasing its capability. Tis is a more efficient and affordable solution and follows DOD’s BBP 3.0 guidance to use modular open systems architecture to stimulate innovation.


INDUSTRY PARTNERSHIP Indeed, we are already seeing industry innovation through the plug-and-play open architecture approach. Vendors understand that the Army isn’t looking for stand-alone devices, but rather an SoS that boosts the overall capability. To create a pathway for


this innovation, PM PNT is engaged in competitive prototyping with industry that will help us execute a better acquisition, ensur- ing that modernization continues for the life of the program.


For example, a recent Small Business Innovation Research contract demonstrated open architecture capabilities on a dis- mounted A-PNT system. Te work showed the ability to change out two different vendors’ GPS cards, different types of inertial sensors and a chip-scale atomic clock in an open environment. Additional prototyping contracts have been awarded for pseudo- lites, and other partners are working on A-PNT prototypes for mounted platforms.


Tese prototyping efforts are a key part of the acquisition strat- egy for A-PNT, as they are helping to define requirements for post-Milestone B engineering and manufacturing development contracts. Like open architecture, early prototyping is a major area of emphasis in congressional efforts at acquisition reform. By executing these efforts prior to Milestone B, we can not only incorporate state-of-the-art technologies and techniques into
