An Inertial Navigation System (INS) that provides reliable position and heading data is a unique backup solution because it allows vehicles to stay on course and maintain awareness of where they are without a GPS connection Home • PNT Library • Land Vehicle Navigation in GNSS-Denied Environments for Defense Applications Land Vehicle Navigation in GNSS-Denied Environments for Defense Applications DOWNLOAD PDF By Anthony Full Problem We Solve In order to safely travel from one location to another during an operation, or maintain navigation capabilities in a contested environment, ground vehicle crews need ways to protect against GPS satellite signal threats and ensure that they reach their intended destination. Operating in a GNSS-denied environment presents challenges to most navigation systems, because they can either be jammed, or deceptively guided off course via spoofing attacks. An Inertial Navigation System (INS) that provides reliable position and heading data without the aid of GPS satellite signals is a unique backup solution because it allows vehicles to stay on course and maintain awareness of where they are as if they never lost connection with GPS. An INS can provide the critical current-location data and ensure that other navigation equipment continues to operate during the mission. Why Is It Important Precise location and navigation capabilities are essential for mission planning, execution and coordination with other units. Inaccurate navigation can lead to mission failure, unintended engagements, or even friendly fire incidents. Ground vehicles in defense operations often navigate in challenging environments where traditional GPS signals are contested or unreliable. This includes dense urban areas, heavily forested regions, or any areas where enemies employ electronic warfare to disrupt GPS signals. Navigating accurately in such conditions is crucial for mission success and the safety of personnel. Therefore, having a robust navigation system that can provide both location of the vehicle real time as well as its precise orientation and direction/heading is of paramount importance for defense applications. In the figure above, we can see that when a vehicle passes through an GNSS-denied area, its navigation system might be thrown off and report a different location compared to the true position. However, with an accurate INS, it can continue along the intended route as well as stay free from excessive drift. Drift occurs when the navigation system is not using external signals for navigation, but rather evolving in pure inertial conditions and over time, the accuracy worsens. Of course, there are different grades of accuracy for navigation depending on your needs. And we’ll cover the most relevant solutions next. How We Solve it Safran has developed a dependable inertial navigation system – The Geonyx – that provides route guidance in GNSS-denied environments. The Geonyx ensures that the vehicle can navigate effectively in spite of satellite signal interference. It incorporates HRG technology and, unlike GPS, INS does not rely on external satellite signals for navigation and heading. Instead, it uses motion sensors and rotation sensors to calculate the position, orientation and velocity of the vehicle based on internal data. The Geonyx will output coordinates of the vehicles current location as well as the data on its intended position to the vehicle’s battle management system (BMS). The Geonyx is able to maintain an outstanding level of accuracy of a couple meters after tens of miles of pure inertial navigation. GEONYX INERTIAL NAVIGATION SYSTEM Geonyx is a combat-proven INS solution for ground vehicles, augmenting battle management systems. With its ruggedized design, it offers a virtually unlimited and maintenance-free lifespan. It can achieve a heading accuracy as good as 0.5 mils thanks to HRG Crystal technology. It has quick and flexible alignment – even in GNSS-denied environments. DOWNLOAD PDF

It is an innovative new atomic clock designed to meet core requirements for military ground and mobile radio communications applications. While maintaining the same volume as a standard oven-controlled crystal oscillator (OCXO), it provides better holdover and higher stability with the lowest power consumption amongst other miniature atomic clocks (MACs) in the market. It can be a drop-in replacement for many applications. The mRO-50 is lower cost than a Chip Scale Atomic Clock (CSAC), and due to its superior performance, small footprint, and low power consumption, it can be applied to many different applications. Namely, in telecommunications systems, it can improve the data throughput performance of networking waveforms, along with many non-networking waveforms. It can do this because its superior holdover and Allan deviation reduce the size of the guard bands, maximizing the volume of information that can be passed between radios. Figure 1: Orolia's mRO-50 The transfer and acquisition of time in DoD and commercial applications from both GNSS and non-GNSS sources has become an important topic in recent decades with greater demands for precision. Many atomic clock products have been designed to strike a balance between performance and cost that allow these goals to be met. This paper describes how the use of the mRO-50 addresses problems that can be seen on ground or mobile platforms using the LTE waveforms as example. The importance of oscillator holdover and the benefits of synchronizing radios in the field are also discussed. The SWaP-C of the mRO-50 now opens the door for systems integrators to use atomic clocks in manpack and vehicular radio applications, replacing what has traditionally been a TCXO. Modern radio communication requires that the transmitter and the receiver are tightly synchronized. This is to allow faster frequency hopping as well as the ability to network at high data rates largely due to a reduction in the size of the “guard bands”. A great example of the benefits of time synchronization is LTE, a commercial networking waveform that is focused on high data throughput. The evolution of this waveform is indicative of the evolution of other, similar waveforms. Referencing table 1 below, one can see that the time/phase requirement of LTE is 1.5us, and the time/phase requirement of LTE-A is 500ns. In one generation, the waveform’s synchronization requirement got tighter by a factor of 3. Table 1: LTE and LTE-A Requirements For commercial radios, such as cell phones, a high precision sync can be achieved using commercial GPS.The problem with relying on GNSS signals is that, in military applications especially, they can become unavailable due to jamming and spoofing by adversaries- or by natural effects, such as “urban canyons”, or natural canyons, blocking a direct line of sight to satellites of interest. There are also instances in cities and in the field where devices can enter these areas for extended periods of time. In these GPS denied environments devices can no longer sync using GPS, forcing the device into holdover. When in holdover it is important for radios to maintain a precise clock. Though some waveforms have features to help keep them synced without GPS, these features limit data throughput because they use bandwidth for sending sync pulses instead of data. In many commercial devices the oscillator will quickly drift away from the actual time. Below we can see a comparison of holdover performance of common Oscillators using LTE and LTE-A as reference. Figure 2: mRO, OCXO, and TCXO Comparison When coming out of holdover, if a device is out of sync with its peers, it will need to synchronize before any meaningful communications can be performed. In this situation, many waveforms will need to enter a “cell search” mode or some equivalent form of peer synchronization prior to communicating. A cell search will waste time (it can take minutes for this sync to complete)- and it will force the user to perform multiple transmissions, increasing the opportunity of detection by an adversary. If, on the other hand, an atomic clock is used (such as an mRO-50)- and synchronization is maintained, the user can immediately start communicating- without the need for a cell search. Guard Bands The waveforms used in modern military radios operate by assigning time slots to users to allow them to simultaneously pass information (as observed by the operator). This technique in telecommunications is known as time division multiple access (TDMA). Thus, if there are many users in a group, such as an infantry platoon, then they can all transmit and receive on the same frequency, as the precise transmit and receive times are sliced and allocated amongst the users. Each time slot, however, requires some time at the start and at the end, known as “guard bands”, to prevent the radios from “talking over each other” and destroying the message. If the radios are all perfectly synchronized, then the guard bands can be reduced to zero- and data throughput is maximized. In reality the radios are not well synchronized, and these guard bands can become significant, wasting valuable spectrum that could otherwise be used to pass more data. Thus, by improving the synchronization of the radios, the telecommunications system can maximize the data that can be passed over the air. The mRO-50 improves the timing synchronization, compared to a standard CSAC, by an order of magnitude due to its superior Allan deviation, bringing the system close to the ideal data throughput. Figure 3: Why does sync matter? Low SWaP-C, high precision atomic oscillators such as the mRO-50, also open the possibility for usage in UAV sensor payloads. These payloads often use GNSS to synchronize their clocks with other parts of the system. GPS outages can be problematic for both the UAV’s communications links and its inertial navigation systems (INS). The high stability of the atomic clock as the INS time base reduces the time integration error drift during extended GNSS outages, along with the telecommunications benefits already discussed. When the GNSS signal is disrupted, the UAV switches to the stable time base provided by the mRO-50 and can “coast” without a signal to maintain operations. The superior holdover time, offered by a mRO-50, allows the user to coast for a very long time. In fact, even when compared to a standard CSAC, the mRO-50 holdover time is more than 5x better in one day. New possibilities for telecommunications systems and UAV sensor payloads have been realized with the advent of low SWaP-C atomic clocks, such as the mRO-50. Early adaptations of these advanced technologies keep our warfighters equipped with the best technologies and provide them with the tactical edge on the battlefield. Conclusion The importance of precision in the acquisition of timing from GNSS and non-GNSS sources has increased in recent decades. Many atomic clock products have been designed to strike a balance between performance and cost that allow this new degree of accuracy to be met. The mRO-50 is Orolia’s new low SWaP-C Miniaturized Rubidium Atomic Clock, specifically designed to meet core requirements foreground, and mobile radio communications applications in terms of weight, size, and performance. It will enable more advanced telecommunications systems and the resilience of UAVs and other GNSS dependent technologies. This technology can be a drop-in replacement for a simple upgrade, yielding superior performance in various applications. DOWNLOAD PDF

In an environment without landmarks, naval vessel crews require precise navigation, autonomy and endurance. The Argonyx serves as an exceptional backup solution by providing dependable position and heading data without relying on GPS satellite signals. Home • PNT Library • Surface Vessel Navigation For Defense Applications Surface Vessel Navigation For Defense Applications DOWNLOAD PDF By Anthony Full Problem We Solve In an environment without landmarks, naval vessel crews require precise navigation, autonomy and endurance. Moreover, with the threat on GNSS Global navigation satellite system (GNSS): A general term describing any satellite constellation that provides positioning, navigation, and timing (PNT) services on a global or regional basis. See also signal jamming and spoofing, ship operators need ways to protect against GPS satellite signal threats and ensure that they know where they are and where they are headed. Operating in a GNSS-denied environment presents challenges to most navigation systems, because they can either be jammed, or deceptively guided off course via spoofing attacks. The Argonyx serves as an exceptional navigation solution by providing dependable position and heading data without relying on GPS satellite signals. This allows sea vessels to maintain their course and positional awareness seamlessly, even in the absence of GPS connectivity. The Argonyx offers essential current-location data and guarantees the operational continuity of other navigation equipment throughout the mission. Why Is It Important Accurate navigation and positioning are crucial for strategic mission planning, execution, and coordination with allied units. Navigation errors can lead to mission failure, unintended engagements, or friendly fire incidents. Sea vessels, from nimble patrol boats to massive aircraft carriers, must navigate through diverse marine environments where traditional GPS signals may be weak or obstructed. These environments can range from the open sea to coastal areas near adversaries employing electronic warfare to disrupt GPS signals. Ensuring precise navigation under such conditions is vital for mission success and the safety of crew and vessel. A robust navigation system like the Argonyx, capable of providing real-time location and guidance to the next waypoint, is indispensable for maritime defense applications. Even when a vessel enters a GNSS-denied zone, the Argonyx enables it to proceed along its intended route and minimizes drift, a common issue when external signals are not available for navigation. Over time, relying solely on an internal navigation system without external checks can lead to decreasing accuracy. The accuracy needed for waypoint navigation varies based on specific operational requirements, which we address with our tailored solutions. Of course, there are different grades of accuracy for waypoint navigation depending on your needs. And we’ll cover the most relevant solutions next. How We Solve it Developed for the demanding needs of naval operations, the Argonyx offers reliable route guidance in environments where GNSS signals are compromised. Utilizing advanced inertial navigation system (INS) technology based on HRG (Hemispherical Resonator Gyro), the Argonyx does not depend on external satellite signals for navigation and heading. Instead, it calculates the vessel’s position, orientation, and velocity using onboard motion and rotation sensors. The system provides the vessel’s current location and intended position data to the ship’s navigation or combat management system, maintaining accurate positioning for up to 72 hours. ARGONYX INERTIAL NAVIGATION SYSTEM The Argonyx is a battle-tested INS solution tailored for sea vessels, enhancing their navigation and combat management capabilities. Its rugged design ensures a long and maintenance-free service life. The system achieves exceptional heading accuracy (<0.01° RMS) through HRG Crystal technology and offers quick and adaptable alignment, even in GNSS-denied conditions. DOWNLOAD PDF

The interference threat information provided from a Controlled Reception Pattern Antenna (CRPA) combined with reliable PNT sources, such as the Safran VersaPNT and Geonyx systems, can deliver situational awareness information, such as the approximate position of interference threat sources. Home • PNT Library • Interference Threat Position Awareness Interference Threat Position Awareness DOWNLOAD PDF By Garrett Payne and Dylan Dayton Real-time interference detection for Situational Awareness (SA) The interference threat information provided from a Controlled Reception Pattern Antenna (CRPA) combined with reliable PNT sources, such as the Safran VersaPNT and Geonyx systems, can deliver situational awareness information, such as the approximate position of interference threat sources. A CRPA was integrated with a Geonyx system and tested operationally.. The CRPA, combined with the accurate heading of the Geonyx, proved to provide robust threat direction finding abilities. Technology Used CRPA Antenna A CRPA is a type of antenna system featuring multiple antenna elements designed to enhance the resilience and performance of Global Positioning System (GPS) receivers by mitigating interference VersaPNT The VersaPNT is a robust Position, Navigation, and Timing (PNT) solution and can be configured to use external PNT sensors and devices which include but are not limited to a CRPA. Geonyx The Geonyx is a land true-inertial navigation, target geolocation & artillery pointing system. CRPA Interface The interference direction-finding system utilized a Novatel GAJT-710 (7-element CRPA) for detecting interference and providing information on detected signals. The GAJT-710 provides interference detection on both GPS L1 and L2 bands and can detect up to 6 simultaneous threats per band. The system parsed the data feed from the CRPA to get information of detected interference and calculate relative directions to suspected threat emitters. Geonyx Interface The interference direction-finding system utilized a Geonyx system for providing position and heading data for absolute positioning. The VersaPNT has also been used to provide position and heading data, similar to the Geonyx. With knowledge of the absolute position and heading of the system, the absolute direction to detected interference can be calculated. The CRPA provides interference relative to antenna heading. Assuming the pointing angle between the CRPA and the Geonyx is known, the relative angles of interference can be converted to absolute angles. GUI Creation and Use The prototype UI shows the threat information detected from the CRPA in real time: • Signal strength, azimuth angle, and elevation angles are shown for detected threats on L1 and L2 bands. • Lines of bearing are calculated using the absolute position and heading from the Geonyx and can be shown on a map. Future Work The prototype ran on separate hardware, so the next step of integration will be to integrate directly on existing navigation/timing systems. Systems will directly intake the CRPA feed and use internal position and heading for calculating absolute bearing to threats. Threat lines of bearing will be shown on system WebUI and updated in real time. Algorithms will be developed and refined for calculating the absolute position of threats based upon lines of bearing. With enough system movement, the changes in lines of bearing over time can be used to detect the position of threat emitters. DOWNLOAD PDF

​This C4ISRNET white paper highlights measures to assure maintainence of critical operations for U.S. forces; featuring Tyler Hohman of Orolia Defense & Security. Protecting the U.S. Military From GPS Jamming and Spoofing U.S. troops first used GPS to create an informational and navigation advantage on the battlefield during the 1991 Persian Gulf War. The success of GPS and the PNT advantage led to a huge increase in the technology’s use by the military. However, as the United States has relied more on GPS, any absence of these Positioning, Navigation, and Timing (PNT) capabilities has led to greater risk. U.S. forces who need GPS to provide critical, precise information may lose their operational advantage without it. U.S. adversaries have learned that this vulnerability can be exploited. If they can deny U.S. forces the advantage of GPS-based PNT capabilities, they can reduce their effectiveness. This white paper from C4ISRNET discusses how preparation and countermeasures can assure U.S. forces maintain critical capabilities.
