LF Receivers
UrsaNav provides receiver technology and products for the Low Frequency (LF) Positioning, Navigation and Timing (PNT) market. Customers include those who rely on the Long Range Aid to Navigation (Loran) and enhanced Loran (eLoran) systems to provide positioning, navigation, and timing independent of Global Navigation Satellite Systems (GNSS), such as GPS. Along with our receivers, UrsaNav has a team of experts that has worked with LF receiver technology for the past 20 years and has recently incorporated the latest technology through acquisitions of Locus, Inc. and CrossRate Technology, LLC. We provide receivers that meet the most demanding performance requirements and product specifications, including a Stratum 1 frequency standard and UTC time recoverability to better than 50 nanoseconds and a positioning and navigation accuracy to within 8 to 20 meters* when GPS is not available.
* Accuracy is achieved using published signal propagation corrections or ASFs and real-time differential corrections.
