GPS applications are vulnerable to signal interference, spoofing and degraded or denied services. Both intentional — jamming — and unintentional signal interference can cause inaccurate PNT and poor navigation performance.
While the use of GNSS jamming and spoofing can be detected on the ground and by aircraft overflying locations where the activity is taking place, these signals can be more comprehensively studied from space using satellites carrying receivers with appropriate spectrum coverage.
In the coming months, we will steadily increase our coverage of complementary PNT companies, products and services, including those based on low Earth-orbiting (LEO) satellites, because they are an increasingly important component of the PNT industry.
In early 2015, the Navigation Support Office of the ESA and the Japan Aerospace Exploration Agency (JAXA) began a collaboration. The ESA-JAXA collaboration is designed to cross-validate Japan’s Quasi-Zenith Satellite System (QZSS) Precise Orbit Determination (POD) results and share expertise to improve the POD accuracy of QZSS.
In this cover story, executives from seven companies present their perspectives on the GNSS/PNT challenges faced by U.S. and allied military forces, their market niche in this area, and their latest products.
