Tools to Support Assured PNT

GPS Source creates tools that support the US Army's strategy for Assured PNT. This includes tools to help reduce SWaP-C (Size, Weight, Power and Cost), increased protection to ensure PNT is available and the ability to receive and distribute M-code.

Global Positioning System (GPS) technology has become an integral part of Mission Command systems and military ground vehicle architectures. It plays an important role in the successful execution of tactical missions.  The term “GPS” conveys positioning, navigation, and timing (PNT) data, data that is essential in virtually every modern weapon system. Precision timing provides joint forces the capability to synchronize operations and communications. PNT also enables precision attack from stand-off distances, reducing collateral damage and allowing friendly forces to avoid threat areas.

The dependence on GPS exemplifies the need for the US military to protect PNT sources to assure unhindered access.  The concept of Assured PNT (A-PNT) is an important topic with military GPS stakeholders around the world. Read more about Assured PNT.


D3 is capable of providing PNT distribution on a mounted platform with true port independence. Each system that is plugged into the D3 has full control over the port from the D3, as if the device has its own DAGR.

It is a smart GPS "Hub" that will perform the function of up to eight GB-GRAMS (i.e. DAGR or similar device).  D3 will distribute ICD-GPS-153 PNT data simultaneously to multiple communication or weapon systems that require GPS information. It is optimized for A-PNT and supports the US Army's System of Systems (SoS) strategy . 

D3 will distribute IS-GPS-153 message to tactical radios, FBCB2/BFT, Laptop/Falconview, MRT's, etc.  It is a cost effective way to distribute secure GPS (A-PNT) data to multiple applications and devices. Read about D3 and how it helps support an Affordable Assured PNT Strategy for Military Ground Vehicles. Read the White Paper: Assured PNT Inside Military Ground Vehicles Using D3


GPS Splitters will convey the GPS signal from one active GPS antenna to multiple GPS receivers. They will enable multiple devices requiring GPS to be connected to one antenna.  (See MS22 and MS24 splitters if redundant antennas are desired.)

GPSS has a complete line of splitters that are ruggedized, waterproof and EMI shielded. Made in the USA, they are designed to meet the rigorous qualifications highly desired by the military.  The standard line is ruggedized, EMI shielded and waterproof.  Special care has been taken to engineer GPS splitters with high IP3 and P1dB figures, allowing them to perform well in the presence of conflicting strong signals and essential for maintaining the integrity of the GPS signal.

MS Splitters (Military Specified Splitters) have been designed and/or tested to the following MIL standards:  MIL-STD-810, MIL-STD-1472,MIL-STD-202, MIL-STD-883,MIL-STD-704, MIL-STD-5400, MIL-STD-454, MIL-STD-1587, MIL-STD-461F, MIL-STD-1275. 


GPS retransmission systems designed by GPS Source for the military provide GPS coverage within any aircraft or ground vehicle.  This means any handheld military or commercial GPS receiver, precision air drop guidance unit (JPADS) or Military Free Fall (MFF) receiver will acquire L1/L2 and GPS protected signals inside the aircraft or ground vehicle.  The Warfighter will have satellite connectivity and situational awareness prior to dismounting a vehicle or exiting an aircraft.
