Resilient Positioning, Navigation, and Timing (PNT)

Space-based PNT is crucial for national security and commercial activities. CACI’s breakthrough precision technology provides secure, highly accurate sub-nanosecond time synchronization for critical missions in the challenging space environment.

Advancing Space Resiliency

CACI experts enhance and secure missions that rely on space-based precision timing and synchronization for remote sensing and communications. We know and understand how to leverage cost-effective, two-way time transfer (TWTT) and clock modeling technology to enhance and deliver highly precise timing and long-term frequency stability that enables GPS/GNSS-independent time and frequency sources. This allows users access to sustained, resilient PNT even in a GPS-denied environment.

Trusted PNT Capabilities

CACI has invested extensively in developing breakthrough low-size, weight, and power (SWaP) precision TWTT and modeling technology that delivers sub-nanosecond time-synchronization. Our PNT capabilities provide a “fail safe” for the GPS constellation in an increasingly contested space environment.

This precise, resilient timing technology forms the basis for further enhancements, such as:

  • Improved geolocation for greater targeting fidelity
  • Fusing PNT payload applications with other data sources
  • One-way time transfer (OWTT) from low Earth orbit (LEO) in contested environments
  • Detect and locate spoofing and jamming for greater GPS resiliency
  • Adaptable waveform flexibility for improved equipment integration

Enhanced Space Systems

CACI is partnering with York Space Systems to launch a demonstration satellite (DemoSat) in 2023 that will deliver a specialized multi-mission PNT and tactical intelligence, surveillance, and reconnaissance payload (TacISR) onto orbit. The TacISR payload will deliver low-cost, high-speed dedicated ISR for special operations missions and other forces that operate in austere locations, as well as provide advanced collection and geolocation of RF signals with one satellite “single ball geolocation” capability. Both payloads will demonstrate CACI’s advances in resilient PNT and TacISR across mission sets by delivering augmented PNT for airborne and ground assets.
