“…By raising power levels high enough, to about -74.8 dBm, it was possible to completely block either GPS or GLONASS reception, but not both. In all scenarios, the combination of GPS/GLONASS allowed at least 40% of the combined number of satellites in-view to remain usable [62].…”

The Time and Frequency Division of the National Institute of Standards and Technology (NIST), an agency of the United States Department of Commerce (DOC), was tasked with fulfilling Section 4, Part (i) of the Position, Navigation and Timing (PNT) Executive Order that was signed by the President on February 12, 2020. The Executive Order states that Within 180 days of the date of this order, the Secretary of Commerce shall make available a GNSS-independent source of Coordinated Universal Time, to support the needs of critical infrastructure owners and operators, for the public and private sectors to access. Although the Executive Order does not specifically provide an accuracy requirement, this report assumes an accuracy requirement of 1 ?s with respect to Coordinated Universal Time (UTC). This specification is assumed because numerous critical infrastructure timing systems in the United States are now heavily dependent on signals received from the Global Positioning System (GPS) satellites that routinely provide sub-microsecond accuracy, and other UTC sources that deliver time at comparable accuracy levels are needed to alleviate or reduce these dependencies. This report was written to describe, propose, and recommend technical methods that NIST has already implemented, or can potentially implement, to fulfill Section 4, Part (i) of the PNT Executive Order.

The multi-source common-view disciplined clock (MSCVDC) is a recent NIST invention designed to support critical infrastructure timing systems that require a verifiably accurate and fail-safe clock. This paper introduces the MSCVDC, provides a technical description of how it works, and discusses its reliability, redundancy, security, and performance. It also discusses the possibility of a commercially available MSCVDC product.

“…The data were processed using the signal software-processing platform, and the fusion positioning was done using opportunity signals (SOPs). In another article, [5], the pirent TM GSS6700 GNSS signal simulator (Spirent Communications plc, Paignton, UK) was paired with an interference signal generator through a Spirent TM GSS8366 device to construct quasi-real dynamic trajectories. Signal-power degradation, navigation solution availability, Dilution Of Precision (DOP), and positioning accuracy were all evaluated as part of the performance evaluation.…”

Quasi-Real RFI Source Generation Using Orolia Skydel LEO Satellite Simulator for Accurate Geolocation and Tracking: Modeling and Experimental Analysis

et al. 2022

Accurate geolocation and tracking of Radio-Frequency Interference (RFI) sources, which affect wireless and satellite systems such as Global Navigation Satellite Systems (GNSS) and Satellite Communication (SatCom) systems, are considered to be a significant issue. Several studies connected to civil and military operations on this issue have been investigated recently. The literature review has surveyed many algorithm simulations for optimizing geolocation and target-tracking estimation. Although most of these algorithms have their own advantages, they have weaknesses, such as accuracy, mathematical complexity, difficulties in implementation, and validation in the real environment, etc. This study has been concerned with investigating the accuracy of geolocation and tracking under high speed and powerful rotation using extracted data from the Orolia Skydel simulator, which simulates the space environment involving Low Earth Orbit (LEO) satellites as sensors and Unmanned Aerial Vehicles (UAV) as RFI emitters. Various scenarios modeled using the Orolia Simulator for quasi-real dynamic trajectories of LEO satellites have been created. The assumed approaches have been verified by Cramer–Rao Lower Bound (CRLB) and Posterior CRLB (PCRLB) to determine the increase in Root Mean Square Error (RMSE) value. The simulation scenarios have been performed using the Monte Carlo iteration. Eventually, the overall achieved results of the considered approaches using data acquired from the Orolia Simulator were presented and compared with theoretical simulation.
