What UrsaNav Brings to Every Project

We trace our Loran roots back to the early 1970’s. We have the most experience and expertise, both in the past and today. Recent entrants, or re-entrants, into the Loran market have web sites that repost articles and news developed by others, tout expertise in other markets, or claim unproven technology. UrsaNav has been fully engaged in remaking the global markets for Loran since the U.S. Government terminated its Loran-C program in 2010 and NELS terminated most of its operations in 2015.

We are committed to improving the operational capabilities of our signal provider and end-user customers. We excel at bringing all the resources together in a collaborative fashion: customers, users, vendors, and academia. We ensure that we approach every professional undertaking with the goal of turning problems into solutions and ideas into execution. We deliver an uncompromising level of product and services quality.

Our company is not just a provider of technological solutions. UrsaNav is a global partner for governments, federal and military, and critical infrastructure providers looking to attain the type of stability and accuracy needed to keep navigation and timing on track.
