Home' Army Acquisition Logistics and Technology Magazine : Army ALT October-December 2016 Contents Congress, "Having accurate PNT information is fundamental to
our forces' ability to maintain initiative, coordinate movements,
target res and communicate on the move." Other senior lead-
ers agree. (See sidebar.) To equip Soldiers to safely navigate and
communicate in any environment, meet current threats and pace
the emergence of threats, we must integrate new capabilities in
the eld and invest in the future to ensure that we continue to
overmatch our adversaries.
e increased e ciencies objective addresses systemic issues in
the adoption of GPS technologies that have resulted in redun-
dant procurement and integration costs. ese redundant costs
are associated with the use of multiple GPS receivers on the same
platform, with resultant power and weight burdens on mounted
platforms and on the Soldier.
e third objective addresses DOD's plan to modernize the
GPS capability to M-Code. is requires replacing most of the
hundreds of thousands of GPS receivers already integrated into
our weapon systems with receivers that are M-Code compatible.
We are working to achieve this mandate at the lowest possible
cost through platform distribution of PNT, open systems archi-
tectures, and thorough systems engineering to ensure that we
procure M-Code receivers that meet Army requirements. A ord-
ability is about being a responsible steward of taxpayer dollars,
and we take this very seriously.
To achieve these objectives, A-PNT combines materiel solutions,
such as GPS, sensors and other technologies, into an architec-
ture that brings increased reliability and security. is approach
makes A-PNT a holistic system-of-systems (SoS) capability for
which one aspect alone is not su cient. For example, if a dis-
mounted Soldier has a requirement for his PNT device to have a
certain level of accuracy, pseudolites (or pseudo-satellites, acting
in place of GPS) can be used to send radio frequency signals to
the dismounted device. e sum of these parts working together
is how the requirement is ful lled. e capabilities complement
one another in order to provide our forces with unhindered
access to trusted PNT information in all conditions.
e SoS architecture approach also will reduce size, weight and
power (SWAP) for the war ghter and platform by decreasing
the number of individual GPS devices a Soldier or vehicle needs
to carry. For example, one of the solutions within the A-PNT
capability is the D3 (Defense Advanced GPS Receiver (DAGR)
Distributed Device). e D3 provides a single platform for
simultaneous distribution of PNT data to multiple systems that
require secure GPS information. It is the rst product that com-
plies with the PNT SoS architecture, and it is currently being
installed on the M1200 Armored Knight vehicle.
For mounted platforms, D3 is a key component of the A-PNT
capability---eliminating redundant systems and simplifying
future migrations, which over time will reduce costs. With D3,
the Army has one PNT device servicing up to eight clients. is
allows us to remove antennas, power cables, data cables and GPS
receivers that are no longer needed from the vehicle. e D3 is
also upgradable to M-Code.
SENIOR DOD LEADERS
SPEAK OUT ON PNT
"While DOD will of course continue to support the
GPS satellites, which we engineer and launch ... we
also need to find alternatives for military use that are
more resilient and less vulnerable."
---Secretary of Defense Ash Carter
"Enhancement of positioning, navigation and timing
is critical to the Army."
---Secretary of the Army Eric Fanning
"We're investing in the development of assured PNT
enablers. This provides access to trusted PNT infor-
mation, while responding to numerous threats."
---Ms. Steffanie B. Easter,
Principal deputy to the assistant secretary of the
Army for acquisition, logistics and technology
PM PNT is engaged in competitive
prototyping with industry that will help
us execute a better acquisition, ensuring
that modernization continues for the life
of the program.
