BEYOND GPS


MULTISYSTEM SUPPORT An M777 howitzer crew assigned to the 2nd Battalion of the 17th Field Artillery Regiment, 2nd Stryker Brigade Combat Team, 2nd Infan- try Division (2-2 SBCT) loads a 155 mm round in preparation for firing during the unit’s Divi- sion Artillery Readiness Test in October 2015 at Yakima Training Center, Washington. PNT data is used in Army systems as diverse as the M777, Stryker, Nett Warrior and Rifleman Radio, requiring an enterprise approach to as- sured PNT.

(ASA(ALT)) recently streamlined the A-PNT acquisition process by designat- ing the PNT program office as a direct reporting program manager to the ASA(ALT). Tis designation enables a faster decision cycle, resulting in the delivery of enhanced capabilities to the Soldier in a compressed timeline.


Managing the program through ASA(ALT) allows

approach to assured PNT and prevent an uncoordinated approach by programs with redundant solutions. Te structure also enables Program Manager (PM) PNT to plan for the cross-PEO integration efforts required to outpace threats and increase efficiencies in PNT implementation.


Against this backdrop, pseudolites were the first of the family of A-PNT systems to receive a milestone (MS) decision.

CONCLUSION While we think of GPS as the gold standard, it is simply one materiel solu- tion to deliver PNT. As the technology and threat landscape continue to shift, the A-PNT program is breaking ground with several alternative means to provide trusted PNT data to Soldiers.


As the first A-PNT element “out of the gate,” the Pseudolite program is using

In May 2015, the subprogram received an MS A decision to enter into the technology maturation and risk reduc- tion phase. PM PNT is now leveraging industry expertise in GPS and GPS alternatives through competitive proto- typing. Each company is charged with delivering pseudolite prototypes and laboratory testing. Tis lab testing will provide the government with data to assess the capability of the prototypes up to Technology Readiness Level 6 in preparation for an MS B review.


an accelerated acquisition approach to deliver modular, scalable technology that is flexible to BCT commanders’ needs, integrates with current equipment and can smoothly incorporate future evolu- tions in antennas, receivers and other technology. Each step in the process takes us closer to the ultimate vision for a pseudolite: a Soldier can turn it on, and the pseudolite will be able to determine its PNT anywhere in the world, without the aid of the GPS constellation, and be totally transparent to the user.
