How inertial and alternative PNT can mitigate GPS vulnerabilities

May 26, 2021  - By

Spirent Federal Systems logoWhile GPS will always be an integral and irreplaceable part of positioning, navigation and timing (PNT) technology,  assured PNT must take a layered approach for true resiliency.

A GPS World webinar sponsored by Spirent Federal Systems will explore this topic. Registration is now open for the free webinar, which will be held June 24.

Join experts from Spirent and Northrop Grumman as they examine

  • the future of inertial navigation in assured PNT and GPS augmentation
  • EGI-Modernization
  • coherent GNSS and inertial sensor emulation
  • exploring and simulating emerging alternative space-based PNT RF signals.

Expert presentations will be followed by a question-and-answer session; questions will be accepted both before and during the webinar.
