Addressing Threats to GPS/GNSS

The potential vulnerabilities of the military’s dependence on Global Positioning System (GPS) and Global Navigation Satellite System (GNSS) data are driving demand for new deployed approaches for detecting threats. In GPS/GNSS-denied environments, ensuring accurate Position, Navigation and Timing (PNT) information is delivered to the warfighter is absolutely critical.

Curtiss-Wright is developing rugged subsystems that deliver A-PNT services, designed to compensate for the loss of GPS/GNSS data and provide an alternative resource that enables GPS data to be trusted if an adversary attempts to deliver spoofed PNT data. With data derived from the combination of a Ground Based GPS Receiver Application Module (GB-GRAM), Inertial Navigation System (INS), Chip Scale Atomic Clock (CSAC), and other Complementary PNT services, Curtiss-Wright A-PNT solutions help enable the warfighter to establish “Assured PNT truth.” Learn more in our Bringing Assured Positioning, Navigation, and Timing to the Field: Why a Holistic Approach is Needed white paper.
 

Proven Technology for Trusted PNT

Curtiss-Wright’s A-PNT solutions are designed to provide ground vehicles with access to trusted PNT information while operating in conditions with limited, impeded, or denied GPS/GNSS. Curtiss-Wright’s A-PNT solutions are cost effective, simple to configure, and rapidly deployable, as well as size, weight and power (SWaP)-optimized for both combat and tactical wheeled vehicle platforms to ease the integration of software and hardware elements required by the warfighter to effectively conduct operations in a GPS/GNSS-denied environment.

By distributing the best available PNT data simultaneously to multiple platform applications that require GPS/GNSS data, Curtiss-Wright A-PNT solutions eliminate the need for a ground vehicle to support multiple GPS/GNSS receivers or antennas. Curtiss-Wright’s A-PNT solutions meet legacy GPS/GNSS distribution requirements and are compatible with standard accessories, such as antennas, configuration cables, and all serial interface cables. They are designed to support both legacy and future technology, including interfacing to mission equipment, as well as Anti-Jam Antenna and tactical communications.

 

VPX3-673 CMOSS A-PNT & Radial Clock LRMMAE 2020 Award Winner

The VPX3-673 is a specialized single board computer and timing card designed to eliminate the need for multiple in-platform boxes to field new navigational capabilities and simplify the integration of complementary PNT sources on ground vehicles. Aligned with the U.S. Army’s C4ISR/EW Modular Open Suite of Standards (CMOSS) and OpenVPX Timing module standard, the SWaP-efficient VPX3-673 delivers state-of-the-art technology services, including a GPS/GNSS Receiver, Chip Scale Atomic Clock (CSAC), and an on-board Inertial Measurement Unit (IMU) – all within a single slot.

The VPX3-673 is also ideal for radial clock distribution applications and can provide a server for various low-power timing services. Serving as a low-skew clock master powered by a GPS-disciplined CSAC, the module offers a variety of configurable clock reference sources and support for up to 16 synchronized clock outputs.

See why the VPX3-673 won Gold at the 2020 Military & Aerospace Electronics Innovators Awards.

 

DBH-670A Digital Beachhead Ethernet Switch and Vehicle Management Computer

Curtiss-Wright’s DBH-670A Digital Beachhead combines an Ethernet switch with a powerful Vehicle Management Computer to provide essential network services to ground vehicles. The DBH-670A is available with pre-integrated VICTORY software, providing VICTORY Data Bus and Platform services, including Management, Access Control, Data Protection, and network distribution of GPS/IMU data such as time, position, orientation, heading, speed, etc. An optional internal GPS receiver provides additional SWaP savings.

Housed in a small and lightweight rugged chassis, the DBH-670A also features a multi-core Arm-based Vetronics computer, with flexible interfaces to monitor and control essential vehicle systems. A large number of vetronics interfaces combined with a powerful software framework simplifies the integration of the DBH-670A into new and legacy vehicles.
