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.
Honeywell has launched the HGuide i700, an inertial measurement unit (IMU) that delivers high-accuracy performance for unmanned air, land and sea vehicles. By pairing near navigation-grade capability with a no-license-required (NLR) classification, the HGuide i700 provides integrators worldwide with a powerful new option for critical sensing and navigation.
The HGuide i700 uses high reliability sensors and electronic architecture found in Honeywell’s HG3900 inertial measurement unit (IMU). Compact and low power, the HGuide i700 delivers near-navigation-grade accuracy and reliability while being optimized to support longer range navigation in GNSS-denied environments
“As customers explore new autonomous, robotic and precision-guided solutions, they want the accuracy and reliability of inertial systems that can be tailored to their program requirements,” said Matt Picchetti, vice president and general manager, Navigation and Sensors, Honeywell Aerospace. “The HGuide i700 offers strong GNSS-denied performance for by limiting maximum acceleration and spin rates in a license-free package that simplifies the complexity of system development while preserving reliability.”
The latest in Honeywell’s HGuide suite of no-license inertial solutions, the HGuide i700 allows customers to streamline development cycles, simplify system architecture and transition to field deployment more quickly than existing technology.
The HGuide i700’s rugged design, compact size and low-power profile make it suitable for diverse commercial, industrial and defense applications, such as:
Unmanned aerial, land or sea vehicles
Mobile mapping and surveying systems
Long duration unmanned ground or surface platforms
Robotics and industrial automation
Stabilized payloads and pointing systems

New offerings will deliver accurate navigation to industrial applications even in areas where GPS is unavailable
The HGuide o360 Navigator. (Photo: Honeywell)
Honeywell has expanded its HGuide industrial navigation portfolio with three new technologically advanced navigation systems — the HGuide o360 INS/GNSS navigator, HGuide n500 inertial navigator and the HGuide g080 GNSS receiver.
The new HGuide products are designed for a wide array of industrial and autonomous applications across air, land and sea vehicles and related equipment.
The HGuide o360 navigationsystem is a compact single-card, all-attitude inertial navigation system (INS) GNSS navigator that can deliver an accurate and robust position and attitude navigation service, even through GNSS-challenged or denied environments, to industrial and autonomous applications. It provides the features and compatibility needed for a simple integration.
“The HGuide o360 is an engineering marvel and a technological breakthrough. There are no similar competing products in the industry today that can achieve such a high-performance level at this price point and size,” said Matt Picchetti, vice president and general manager, Navigation & Sensors, Honeywell Aerospace. “The entire HGuide product line is suitable for a wide range of industries, including autonomous vehicles, marine and a host of industrial applications where accurate positioning and attitude information is required in real time.”
The HGuide o360 INS/GNSS navigator contains a powerful dual antenna, multi-frequency, multi-constellation, real-time kinematic (RTK) GNSS receiver, Honeywell’s i300 inertial measurement unit (IMU) technology, and a high-grade calibrated magnetometer.
The HGuide o360 is designed for platforms that require high-performance navigation data in an ultra-low size, weight and power (SWAP) package.
The HGuide n500 inertial navigator is a navigation-grade bring-your-own-GNSS all-attitude navigator that supports continuous position and attitude navigation even during prolonged GNSS outages. The HGuide n500 is built on Honeywell’s HG4930 IMU plus the Honeywell HGuide Sensor Fusion software.
The HGuide g080 GNSS receiver is a dual-antenna, triple-radio frequency, all-constellation GNSS receiver that delivers heading and positioning down to sub-centimeter levels even in GNSS-challenged environments. It includes an onboard IMU to allow tracking during short GNSS outages and enable smooth and fast reacquisition. The product is available with or without RTK functionality.
Inertial navigation systems are highly critical in navigation and comprise an IMU, a GNSS receiver and sensor fusion software. These components work together to calculate position, orientation and velocity to deliver critical navigation information in GNSS-denied areas such as urban canyons, bridges, tunnels, mountains, parking garages and dense forests.
Stringent testing on both fixed-wing plane and helicopter proves reliability and performance
Honeywell has successfully demonstrated several advanced alternative navigation technologies intended to help ensure seamless navigation, even when GPS signals are blocked, interrupted or unavailable.
Testing took place on both an Embraer E170 aircraft and an AgustaWestland AW139 helicopter.
Alternative navigation systems use sensors such as cameras, star trackers, radars and radios to augment and or aid inertial navigation systems. These systems correct inertial navigation systems in environments where GNSS are denied.
“Our customers are seeing an increase in both intentional and unintentional navigational disruptions, including jamming for GNSS-based navigation,” said Matt Picchetti, vice president and general manager, Navigation and Sensors, Honeywell Aerospace. “There hasn’t been a single set of solutions that meet all our customers’ operational needs, so we decided to create one. Our modular and scalable alternative navigation technologies are setting a new benchmark in terms of reliability and performance in GNSS-denied environments compared with what is available in aviation today.”
Alternative navigation technologies provide vital position, velocity and heading information in GNSS-denied environments. The successfully demonstrated technologies onboard the E170 and AW139 include:
Vision-Aided Navigation. Honeywell’s vision-aided navigation system achieved GPS-like performance on both the Embraer E170 and AW139 platforms during GPS-denied conditions. Additionally, the technology showed 67% improvement in GPS-denied performance compared with earlier testing in 2021. The system uses a live camera feed and compares it with maps to provide a passive, not jammable, and highly accurate absolute position.
Celestial-Aided Navigation. Honeywell’s celestial-aided navigation system on the Embraer E170 achieved an accuracy of 25 meters circular error probability of 50% (CEP50). This represented a 38% improvement in GPS-denied performance compared with tests in 2021. Most importantly, this is the first time a resident space objects-based (RSOs) navigation solution was demonstrated on an airborne platform, as most competing solutions rely only on star-based navigation. The system uses a star tracker to observe stars and RSOs to provide a passive, not jammable solution with GPS-like accuracy in GPS-denied or spoofed conditions.
Magnetic-Anomaly-Aided Navigation. Honeywell conducted real-time magnetic-anomaly-aided navigation on the Embraer E170 airborne platform. This is a historic milestone, as almost all previous magnetic tests were done in special environments to mitigate electromagnetic noise. Honeywell demonstrated this passive, not jammable, all-weather 24/7 technology on an embedded platform, which measures Earth’s magnetic strength and compares it with magnetic maps to accurately identify the position of the vehicle.

Additionally, Honeywell demonstrated that inertial navigation systems, when paired with the GPSDome (an anti-jamming device), showed significant improvement in position accuracy and integrity performance in the presence of GPS jamming. The ability of GPSDome to enable tracking of GPS satellites under more aggressive jamming environments reduces performance degradations that come with GNSS-denied conditions.
Alternative navigation prototype systems will be available in 2022, with initial deliveries expected to start in 2023.

New, smaller sensors provide high-performance navigation at a low cost with less power consumption, company said.
Honeywell has unveiled a new rate sensor to help small satellites navigate increasingly crowded orbits above the Earth’s surface. The new micro-electro-mechanical system (MEMS)-based product provides low cost and power consumption in a smaller size than previous Honeywell offerings, while maintaining high performance levels. It is suitable for customers building smaller and lower-cost satellites, according to Honeywell.
Honeywell’s HG4934 space rate sensor is roughly the same size and weight (145 grams) as a baseball. Compared to Honeywell’s previous rate sensors, it consumes only one-fifth the electric power, is more than 32 times lighter, and is 60 times smaller. It also is more tolerant of radiation, a key attribute in space.
“With this new sensor, our customers can build smaller, lower cost satellites that are just as capable and reliable as their traditional predecessors, which will allow them to field new satellite technologies like 5G telecommunications or high-bandwidth global Internet,” said Mike Elias, vice president and general manager, Space, Honeywell Aerospace. “Furthermore, the number of satellites is only increasing, which leads to more crowded orbits. It’s critical that our customers have highly precise navigation solutions to help prevent accidents, which could knock functional satellites out of orbit.”
A space rate sensor, also known as an inertial reference unit or IRU, is an inertial sensor composed of three gyroscopes that work together to sense rotation rates. They determine an aircraft or spacecraft’s change in rotational attitude over time and allow it to move from one location to another without using any external information. It can also serve as a backup solution to provide redundancy if other navigation systems fail.
Celestial navigation options like star trackers are a popular method of obtaining pointing directions for satellites and spacecraft. This form of navigation uses angular measurements between objects in space (stars, planets, etc.) and the horizon to calculate location. However, sometimes these star trackers are blinded by the sun or affected by thruster gases. In this case, Honeywell’s HG4934 can act as a secondary method of attitude determination.
Honeywell’s HG4934 Space Rate Sensor is available now for commercial, defense, and science applications. The first deliveries to customers began at the end of 2020.
Honeywell has produced a new inertial navigation unit that provides accurate navigation for customers across a broad range of industries including agriculture, robotics and autonomous vehicles, without compromising on size, cost or performance.

The HGuide n580 is the first Honeywell-produced, industrial-focused navigation solution that uses both precision inertial measurement unit technology and GNSS to improve location accuracy even when facing natural and manmade obstacles.
“The blend of inertial and satellite navigation capabilities provided by the HGuide n580 is especially important where precision is required in demanding environments — for example, autonomous cars traveling in cities, where our technology can extend the accuracy and performance of navigational systems while keeping passengers safe,” said Chris Lund, senior director, Navigation and Sensors, Honeywell Aerospace. “Honeywell’s history and expertise in navigation technology enables customers to implement this new wave of advanced technology into their own applications and operations.”
Roughly the size of a deck of cards, the HGuide n580 gives Honeywell’s industrial customers the capabilities needed to navigate accurately in areas with limited satellite coverage, such as densely populated cities where tall buildings, underground tunnels, and multi-layer freeway stacks or bridges often create challenges to traditional GPS navigation.
For a GPS unit to function properly, it requires a strong signal connection between the unit on the ground and multiple satellites in the sky to accurately orient its position. City infrastructure such as buildings and tunnels can temporarily block the signal between GPS unit receivers and satellites, creating urban canyons.
With the HGuide n580 integrated system, Honeywell’s inertial measurement unit technology combines with GPS to act as a backup solution, which means the loss of GPS signal caused by an urban canyon does not result in a complete loss of navigation.
To learn more about the new HGuide n580 solution and Honeywell’s other commercially available navigation technologies, visit the Honeywell Aerospace website.
Long established as a key component within defense applications, navigation technology from Honeywell is now available to a wide range of new industries that can benefit from the advanced precision and performance of reliable, rugged and easy-to-install inertial measurement units (IMUs).
Honeywell’s newest IMU offering — the HG4930 — applies the principles of reliability, dependability and performance from aerospace and defense. It’s tailored for “straight out of the factory” integration and use in various non-defense and non-aerospace industrial applications, the company said.
Applications include autonomous vehicles, surveying and mapping, ground and underwater robotics, unmanned aerial vehicles and gimbal stabilization.
IMUs help people, vehicles and machines measure motion and calculate changes in position, anywhere in the world, even where GPS signals are intermittent. In industries where automation is taking hold and working conditions where GPS may be out of touch, an IMU can help fill in the moments of disconnect and keep things like an autonomous underwater vehicle or a robot in a factory informed about how they are moving relative to their surroundings.
“For more than a decade, we’ve designed our IMUs to perform in the extremely harsh and demanding environments for our aerospace and defense customers,” said Chris Lund, senior director, industrial IMUs, Honeywell Aerospace. “But there is no shortage of possibilities for how that same IMU technology can support a wealth of markets hungry for the next level of enhanced navigation and control. The HG4930 tactical grade IMU is a highly competitive and cost-efficient variant of our industry-leading navigation technology. Whether helping your industry evolve toward autonomy or augmenting a platform or solution’s precision in domains where GPS is unreliable, the HG4930 delivers the needed performance.”
In addition to the HG4930 IMU being an extremely small, lightweight and low-power product for spearheading new uses or bolstering current navigation capabilities, Honeywell’s HG4930 IMU is not classified under an International Traffic in Arms Regulation category, but instead is free from the burden of an export license for all but a few military-related use cases. This means a broader availability for customers around the world.
With more than 500,000 tactical-grade IMUs produced to date, the HG4930 builds on a proven Honeywell legacy of reliable inertial technologies. According to Honeywell, it is the highest-performing microelectromechanical system (MEMS)-based IMU of its size and price, and benefits from world-class inertial sensor development, calibration and compensation.
The HG4930 has been tailored to provide significantly improved gyroscope and accelerometer performance for the environments and use cases experienced by non-aerospace and non-defense users.
For industries that depend on less reliable MEMS or large, power hungry and expensive fiber-optic gyroscopes for navigation and control capabilities, the HG4930 offers three off-the-shelf performance grades for easy replacement and new capability.
