Abstract:	A hybrid radiolocation system concept is introduced to exploit mixed ranging signals from multiple sources. The ranging signals might include any mixture of time-ofarrival, time-difference-of-arrival, round-trip-travel, received signal strength, and angle-of-arrival signals. A direct algebraic position solution method is developed in this paper to insure that a sufficient number and type of ranging measurements are available to maintain navigation filter stability. Example results are provided to demonstrate that the hybrid system can improve position availability in cases where the number of ranging signals is severely limited.
