Honeywell has launched Kestrel, a compact navigation solution designed to help uncrewed aerial systems (UAS) operate reliably in contested environments where GPS signals may be degraded, jammed or spoofed.
Built to support the growing demand for smaller, more affordable and highly efficient platforms, Kestrel combines Honeywell Aerospace’s HG3900 MEMS inertial measurement unit with an M-code receiver and a multi-GNSS receiver. The platform is intended to meet the specific needs of Group 2 and 3 collaborative combat aircraft and loitering munitions platforms. It is also suitable for crewed aircraft where size, weight, power and cost are important considerations.
“Kestrel reflects the evolving needs of today’s uncrewed operations, where operators are looking for resilient navigation technology that is smaller, lighter and more cost-effective,” said Matt Picchetti, vice president and general manager of Navigation & Sensors at Honeywell Aerospace. “This system helps operators maintain mission objectives in environments where legacy GPS systems are lagging behind.”
Kestrel is an Embedded GNSS/INS (EGI) system for global defense and commercial operators in need of advanced inertial navigation technology with secure positioning capabilities in a smaller footprint. The system is 40 percent smaller and lighter than similar navigation products while delivering up to an 80 percent improvement in navigation accuracy for uncrewed platforms. It also reduces costs by as much as 50 percent, helping operators efficiently scale deployment across high-volume drone operations. Kestrel’s resiliency reduces UAS attrition by 60 percent, while more than doubling the capacity for mission distances.
The ability to operate without assured GNSS access is a distinct advantage for any military aircraft operating in contested or GNSS-denied environments because it provides continuous, self-contained position, velocity and attitude estimates independent of external signals.
Kestrel is designed to support a broad range of defense and commercial applications and will be available in configurations that support international and non-ITAR deployments.
Honeywell pioneered EGI technology and has produced more than 60,000 units since the mid-1990s to meet customers’ most challenging navigation, pointing, stabilization and flight-control applications.

To help counter attacks that degrade GNSS capability on combat vehicles, Leonardo DRS developed a modified data-distribution unit computer, the DDUx II, with an embedded assured positioning, navigation and timing (APNT) capability the company calls Assured Positioning, Navigation and Timing Converged Computer Embedded & Scalable (AC²ES). It augments standard military GPS PNT sources with technologies such as anti-jam, anti-spoof, M-code receivers, additional RF sources, vehicle infrared (IR) sensor vision navigation, wheel rotation and inertial measurement units (IMUs). It also offers a choice of multiple timing holdup modules that increase accuracy proportionately with cost.
The DDUx II and military variants, fielded by the U.S. Army and Marine Corps, allow for integration of APNT functionality with the Battle Management System (BMS). It can provide APNT distribution to all other devices needing PNT within the vehicle without adding to its size, weight and power (SWAP).
Following a five-year development program, Leonardo DRS launched the AC²ES in September 2021 as a commercial option while continuing discussions with the U.S. Army and Marine Corps, which have not yet adopted it. “We have tested it,” said Mike Stucki, business development manager for the company’s land electronics division. “We have gone to Army jamming and testing events. We have performance and results. However, it has not been officially tested under the Army or Marines programs, with which we are moving forward this year.”
Leonardo DRS wants to offer the armed services the additional components they need to achieve APNT “and not require them to buy anything they don’t need or want,” Stucki said. Those additional components include multiple GNSS receivers for timing and a low-end internal IMU to provide continuous navigation in case GNSS is disrupted. All these components fit directly into the existing DRS hardware. Under the Mounted Family of Computer Systems (MFoCS) program alone, the Army has fielded more than 100,000 DDUx units. Some vehicles already have high-end INS, wheel encoders, and other sensors, and MFoCS can ingest their data.
Navigating with Infrared
For vision navigation, Leonardo DRS uses software developed by its partner Leidos that ingests data from existing hardware on the vehicles, many of which already have IR cameras. In a GNSS-denied environment, this enables the system to navigate by matching what the IR camera sees to an imagery database. Leidos’ software is based on work it began in 2011 with the DARPA All-Source Positioning and Navigation (ASPN) program.
“Leidos developed algorithms that use these other sensor inputs in the sensor-fusion engine to provide more accurate absolute positioning in a completely RF-denied environment,” said Kevin Betts, PNT director for Leidos. “We take the live images from the vehicle’s existing IR camera and match them to a satellite-derived model of the environment. When the images match, we have an absolute position update that we can provide to the navigation filter.”
MFoCS “is the heart that runs the Blue Force tracker system that the soldiers use,” said Bart Blanchard, director of advanced programs at Leonardo DRS. “We’ve added the APNT components inside that box. They’re leveraging the hardware that they already own. It’s a very cost-effective solution.”
Flexible, resilient military PNT designed for every military environment
Orolia, through its Orolia Defense & Security business, has announced the availability of M-code military GPS receivers in its resilient PNT products and solutions, including M-code-enabled mobile mission timing and synchronization platforms.
M-code capabilities further enhance Orolia’s Versa mobile PNT platform for rugged, small SWaP-C requirements and Orolia’s flagship SecureSync resilient time and frequency reference solution — the first Defense Information Systems Agency (DISA) approved time server.
M-code is a military signal used in the L1 and L2 GPS bands and is required by congressional mandate for U.S. Department of Defense (DoD) military operations. It is designed to enhance positioning, navigation and timing (PNT) capabilities and improved resistance to existing and emerging GPS threats, such as jamming and spoofing.
M-code offers several operational benefits, including a higher power signal with improved resistance to jamming and interference; advanced security features to prevent unauthorized access or exploitation; and improved message formats and signal modulation techniques for faster and more accurate performance.
“As threats against GPS increase, military forces will need M-code capabilities on mobile PNT systems to ensure continuous operations wherever they go,” said Hironori Sasaki, president of Orolia Defense & Security. “Orolia is proud to continue to support Department of Defense initiatives to ensure that warfighters have the most secure, reliable and accurate positioning, timing and synchronization solutions in any environment.”
From resilient PNT solutions to GPS/GNSS simulation, interference detection and mitigation, Orolia provides end-to-end NAVWAR and resilient PNT solutions to protect, augment and strengthen military systems for GPS-denied environments.
In 2019, the U.S. Air Force certified the security architecture of Raytheon Intelligence & Space’s M-code modules and receivers as providers of secure and reliable access to modernized GPS. The resilient receivers are designed for high anti-jam performance.
Raytheon’s M-code application-specific integrated circuit (ASIC) chip is either integrated into a ground-based receiver card optimized for low dynamic applications, or used as an avionics/naval receiver card to support multiple end users.
“Our focus is on taking a comprehensive approach to resilient navigation,” explained Chad Pillsbury, director for Raytheon’s Secure Sensor Solutions. “We provide the complete family of PNT solutions. We start with the fundamental components, like the ASIC chip, and tailor our solution for the platform and mission requirements.”
Open Architecture. Raytheon successfully completed testing of the first M-code receiver onboard the U.S. Air Force’s B-2 bomber in 2017. “Since then, we’ve undergone a number of tests internally and with third-parties. Our M-code receivers have standard interfaces and open architecture protocols, enabling them to work with both U.S. and allied systems. By pairing our M-code receiver with our anti-jam electronics and antenna, our systems enable warfighters to combat the most advanced threats seen in the world today,” Pilsbury said.
The receiver is planned to be incorporated into many fighters, bombers and weapons systems across the U.S. Department of Defense. “We provide enhanced anti-jam, anti-spoof GPS capabilities, as well as alternate navigation and multi-constellation support that represent a significant improvement over the systems currently used by today’s warfighters,” Pillsbury said.
Meeting Advancing Threats. “The hardest part is meeting a changing threat target,” Pillsbury explained. “The fact is the threat is advancing at a rapid rate. Because of that, challenges are constantly evolving.
“That means we had to design solutions that were simultaneously robust and secure, but also flexible and open so we can continually upgrade them. That’s not an easy thing to do.
“But, by taking a comprehensive approach that looked at the whole problem rather than just part of it, we’ve developed systems that address these challenges and have the flexibility to address future challenges.”
Raytheon’s M-code products are now available to the U.S. military and its allies in accordance with International Traffic in Arms Regulations and the U.S. State Department.
Collins Aerospace announced that its miniature PLGR engine – M-code (MPE-M) receiver has received approval from the GPS Directorate. Collins Aerospace’s Mike Shepherd talks more about the approval at Xponential 2019, which took place April 29-May 2 in Chicago.
