As emerging threats evolve and conditions change, it is important to understand when navigation systems are providing accurate, assured data. Information assurance and resiliency is paramount to ensure mitigating risks and mission success. As threats evolve, so do the systems that provide the accurate timing and navigation solutions. Protection and mitigation against these emerging threats is an absolute requirement for any system. However, understanding of the threat as well as situational awareness data as to where this threat may be, is just as important. Combining both pieces provides an even more resilient, assured PNT solution that is not only useful as a navigation and timing system but also as an end-user interface for updated mission critical RF weather data. Orolia Defense and Security’s VersaPNT with Broadshield combines both the protection and mitigation component required of a navigation system as well as the situational awareness component to ensure mission success and mitigating risks.
Orolia Defense and Security’s Broadshield provides GPS jamming and spoofing detection and mitigation using an algorithmic approach. Combining BroadShield’s jamming and spoofing detection algorithms alongside VersaONT’s inertial navigation system provides a single solution capable of situational awareness and threat mitigation.
VersaPNT, using Orolia’s FlexFusion algorithms, combines GNSS receivers, inertial measurement units (IMU), signals of opportunity, high performance timing oscillators and rubidium atomic clocks, and available platform sensors to provide assured resilient PNT. Even in GNSS-degraded or denied environments it generates trustworthy time and frequency signals and position solutions leveraging whatever combination of sensor input or IMU measurement possible in GNSS contested and denied environments. Fully customizable as a navigation system, time server, and time provider both in mobile and stationary applications. With the ability for the VersaPNT to integrate Orolia’s new miniaturized Rubidium atomic clock (mRO-50), high navigation and timing accuracies can be achieved in degraded and denied environments which is crucial for military airborne and ground applications.
VersaPNT, with the Broadshield technology, provides a resilient position, navigation, and timing (PNT) solution. As an integrated solution, the VersaPNT not only provides situational awareness information in the form of jamming and spoofing information to downstream devices, but also uses that information to provide a more accurate PNT solution to any desired end-user. The result is a resilient navigation system that can be integrated into existing systems providing situational awareness and protection to ancillary systems within a vehicle or building.
With this single box solution, the integration time to bridge the gap between conventional PNT solutions and the assured, resilient PNT solutions provided by the VersaPNT can be drastically reduced. The major benefit of the VersaPNT with Broadshield is the ability to use fielded, inexpensive FRPA antennas to obtain the jamming and spoofing detection and mitigation that has been mentioned previously. With the ease of integration of the VersaPNT with Broadshield, not only will new systems be able to take advantage of the resilient, user-aware navigation system, but any currently deployed system can take full advantage of the capabilities as well.
In previous works, the VersaPNT with Broadshield has been tested on a bench top using simulated GPS trajectories and inserting jamming when needed. In this paper, The VersaPNT with Broadshield will be tested on real-world platforms, undergoing jamming and spoofing events while stationary as well as mobile. Position accuracy and timing will be compared against a Truth System to illustrate the high-performance metrics that the VersaPNT can provide not only when GNSS is present but also during the degraded and denied environments as well. Jamming and spoofing events will be plotted on a map to give users a common operating picture of the current GNSS environment. This information can also be used post mission to assess areas where GNSS may have be degraded or denied allowing for mission planning to avoid certain areas or plan to use non-GNSS based solutions in the future.
With emerging threats, understanding the RF environment is just as important as protecting against said adversaries and providing optimal position and timing. The VersaPNT with Broadshield is a platform that can provide our warfighters with the required assured information to not only ensure mission success but mitigate risks.
