A navigation concept is developed that relies on passive one‐way ranging using pseudorange measurements of High‐Frequency (HF) beacon signals. This concept is being developed as an alternative to GNSS positioning and timing services. HF signals are transmitted from ground‐based beacons. If a set of signals reaches the user equipment receiver with sufficient geometric diversity, then the position and the clock offset of the receiver can be determined. Ionospheric modeling uncertainty causes errors in the deduced user equipment position and clock offset that are compensated for by estimating corrections to a parametric model of the ionosphere as part of the navigation solution. A batch filter estimates the user equipment position, clock offset, and corrections to an a priori ionosphere model. In simulated case studies involving significant errors in the a priori ionospheric parameters, the total positioning error is on the order of hundreds of meters in the horizontal plane and tens of meters vertically.
