Raytheon’s Resilient Navigation and Reconnaissance Solutions (RNRS), of Raytheon Intelligence and Space (RI&S), is a leading provider of GPS receiver technology solutions for high performing weapon and avionics applications. Raytheon’s PNT and GPS solutions increase the resilience and capability of the warfighter by providing best-in-class Anti Jam (AJ) and Anti-Spoof (AS) protection against the increasingly contested environment faced on the world stage today.
Raytheon has internally developed a product line of cost effective high performing, low SWAP (Size, Weight, and Power), M code enabled GPS Receivers and Antenna Electronics solutions. This product family, referred to as JRPNT (Jam Resistant PNT), is new to market. This new product line captures the same groundbreaking AJ and AS algorithms featured in Raytheon’s best in class Common Architecture for Assured PNT (CAAP) ASIC, designed for high performing weapons, in a cost-effective FPGA solution, to enable this technology to be available to the broader DoD community in both a federated AJ applique and integrated receiver configuration. The product line provides 4, 5, and 7 element CRPA form factors of both federated AJ Applique solutions, able to be paired with commercially available receivers and M-code enabled receivers alike, and integrated M-code GPS receivers, each designed to support the needs of a variety of platforms requiring high AJ and modernized GPS processing, including UAV, Weapon, Avionic, and Ground applications. Raytheon’s AJ appliques are named based on the number of antenna elements, “JRPNT-4 / -5/ -7,” and the associated family of integrated receivers are referred to as “JAGER – 4/-5/-7”.
This presentation will provide an overview of the architectures, key capabilities, and available form factors of the M Code enabled GPS receiver and federated AJ solutions that make up Raytheon’s JRPNT product line. The presentation will address on-going development efforts, prototyping, demonstration results, recent accomplishments, product development, and production status of these state of the art M code enabled products.
In November of 2022, Raytheon, along with sponsors at AFRL, performed a successful live-sky demonstration at the Holloman Air Force Base Static Antenna Test Range (SATR) to showcase the exceptional Anti Jam performance of these new to market solutions. The demonstration featured Raytheon’s JAGER Weapons Receiver, a high AJ 5 element CRPA based M Code GPS Receiver containing Raytheon’s GPU-PRD-711 certified MGUE Increment 1 M code ASIC, and the JRPNT-7, a high AJ M Code compatible 7 element federated anti jam solution designed for Avionic and Ground applications. The SATR event was overseen by AFRL, and run by the Holloman Air Force Base 746th Test Squadron, who served as test architects, conductors and independent government data collectors.
Raytheon’s products were subjected to a variety of threat scenarios, including continuous wave jammers, broadband jammers, pulsed continuous wave jammers, and sweep sine wave jammers, while tracking a mixed constellation of Y and M code live sky signals, as well as High-Y code. Raytheon’s products demonstrated tracking thresholds under jamming conditions, as well as acquisition and re-acquisition thresholds under a jammed environment. To demonstrate the inter-operability of Raytheon’s federated AJ solutions, Raytheon paired the JRPNT-7 to a Raytheon GB-GRAMM receiver, as well as to a commercially available receiver, to form two high AJ GPS solutions for comparability.
This presentation will provide an overview of the SATR demonstration event, including information at an unclassified level on the test configuration, jammer types and quantity, threat laydowns and test cases, and demonstration results for Raytheon’s products under test. The presentation will address the significance of the resoundingly positive test results for Raytheon’s JRPNT product line development and product technology readiness levels (TRL).
Based on the results of this test, Raytheon anticipates the JAGER and JRPNT products to be the highest performing cost effective solutions available to the warfighter in 2023, able to defeat some of the most challenging jamming threats seen on the world stage today.
