A story published by Geospatial World entitled “Tech Neutral, Diverse Approach Critical for Global GNSS Backup” underscores why there must be multiple forms of positioning, navigation, and timing (PNT) to deliver on the promise of resilient PNT.
In the piece, Michael O’Connor, CEO of Satelles, said that the concept of resilient PNT is “context- and application-specific because achieving a state of resilient PNT for a user, a company, a critical infrastructure sector, or a nation are all quite different things. In other words, resilient PNT takes on different meanings depending on the scale or scope of the application or system that is being protected and backed up.”
The article goes on to cite reports from DOT, DHS, and NIST that not only describe resilience as the goal of the responsible use of PNT but also reiterate how important it is to have diverse technologies that meet the varying operational characteristics required by the owners and operators of the systems and platforms that make up our critical infrastructure. The author references the Open PNT Industry Alliance (of which Satelles is a member), and how the coalition supports an open market with the kind of competition that drives real innovation to create diversity and thus true resilience.
Speaking to the versatility and performance of STL as one of the technologies that can meet many of the specific needs of the market, Christina Riley, VP/GM of Commercial PNT, shared the following insight: “In the LEO PNT category, Satelles offers Satellite Time and Location (STL), a solution that is engineered to provide not only a complementary form of PNT but also a primary source of time in locations where a reliable GPS signal is unavailable, such as interior 5G sites for wireless networks.”
