Positioning, navigation and timing (PNT) solutions all must adhere to stringent standards for accuracy, availability, reliability, and continuity. UrsaNav has decades of experience implementing, testing, and validating Loran and eLoran systems, as well as other common navigation platforms like differential GPS (DGPS). Using sophisticated software simulation and testing, our team can ensure that clients’ PNT solutions are acceptable for real-world applications. We can test to global, industry, and/or customer-specific requirements. We provide installation and certification and also provide service-provider system certification testing per mutually agreed-upon standards.
