Statement of Objectives Task Order 0001: Joint Multi-INT Precision Reference

BAA No.: BAA-RQKS-17-D-1100 03 May 17

1. Background

Previous PNT programs at AFRL have demonstrated the ability to improve airborne platforms’ time and frequency states using various GPS and two-way time transfer technologies and techniques. These technologies and techniques have shown sub-nanosecond relative timing performance and frequency stabilities on the order of 1x10 -10 s/s on dynamic platforms. This performance has been demonstrated using a variety of individual systems including: civilian GPS receivers, military GPS receivers, and RF Two-Way Time Transfer modems.

While demonstrations on individual technologies has taken place, research is still needed on optimal approaches for integrating these systems to aid and complement each other in a hostile environment with evolving threats. Furthermore, missionization of these systems to address operational considerations is needed before they can be more widely adopted. This includes studies on the impacts of cyber and EW denial; and, the reduction of the current size, weight and power of these systems, which is a limiting factor on a number of platforms to which these systems could be deployed. Finally, novel ways to integrate time and frequency standards with aircraft mission systems is needed to ensure optimal performance and flexibility.

The focus of research for the previous effort and this current effort is to enable distributed RF Sensing (multi-statics, distributed ISR, etc), and distributed effects (electronic warfare) for airborne systems. These systems must operate in the dynamic airborne environment and are impacted by errors induced by dynamics and errors in the estimation of the dynamics. It is important to note that errors in position map to errors in time and errors in velocity map to errors in frequency; and beyond this, measurements used to project these estimates to various parts of the aircraft (e.g.

rotation rate errors projecting into level-arms cause velocity errors) map into the time and frequency errors. For the purpose of this SOO, these error sources must be considered when referring to “time and frequency.”

2. Scope Research methods for improving inter- and intra-airborne platform time and frequency for airborne systems by utilizing GPS, free space Two-Way Time and Frequency Transfer (TWTFT), and data bus/wired techniques. Also, as mentioned above, consider time and frequency errors sources induced by dynamics and in the estimation of dynamics for airborne platforms.

3. Technical Objective The research objectives in this task order aim to study techniques and technologies that increase the accuracy, precision, security, and utility of inter-platform TWTFT systems. Additionally, research on intra-platform techniques and technologies to distribute inter-platform time and frequency to mission systems is of interest including the use of open architectures.

3.1. Analyze Cyber Security for RF TWTFT Systems (Basic SOO 3.5)

Today, RF TWTFT systems are optimized for performance over various datalinks. Analyze current published approaches for RF TWTFT systems and recommend approaches and techniques to address cyber and other potential security concerns.

3.2. Reduction of Size Weight and Power Cost (SWaP-C) for RF TWTFT Systems (Basic SOO 3.3)

One of the major contributors of SWaP on current RF TWTFT systems today is the RF front-end.

Perform a trade study on the required specifications for these RF front-ends and perform a market survey on potential COTS solutions which would meet these specifications in a dynamic environment. The goal of this task is to identify solutions to reduce the SWaP-C of RF TWTFT to enable use in small Unmanned Aerial Systems (UAS). Also of interest are low SWaP-C solutions which will enable processing and computation of TWTFT solutions when coupled with COTS RF front-ends.

3.3. Distribution of Position, Attitude and Timing within aircraft (Intra-Platform State Distribution, BASIC SOO 3.1, 3.6)

Describe the best technologies and techniques to distribute navigation state parameters to systems within military airframes (Intra-platform time and frequency distribution) to enable distributed RF Sensing (ISR) and effects (EW). Technologies and techniques should consider both current and future wiring and data communication methods available on military aircraft. Also of great interest are current and upcoming open architecture standards for the distribution of navigation state parameters.

3.4. Time and Frequency Requirements for Distributed RF Sensing and Effects Missions (Basic

SOO 3.2)

Conduct a sensitivity analysis on the effects of degradation of precision and accuracy for position, accuracy and timing on single and multi-platform distributed RF sensing and effects (e.g.

geolocation; single and multi-platform electronic warfare; mono-static, bi-static, and multi-static radar, etc.) Deliver simulations and models developed under this task used to perform the sensitivity analysis.

3.5. Convergence of Com and Navigation on Tactical Datalinks (Basic SOO 3.6)

Study the compatibility of time and frequency transfer techniques with tactical datalinks including: Link-16, MADL, CDL, etc. Provide recommendations on upgrades to future systems to enable the convergence of communication and navigation functions. Provide constraints and performance limits of the recommendations.
