Abstract: A device implementing an adaptive positioning system may include at least one processor that is configured to concurrently implement a first positioning system that generates first positioning information items and a second positioning system that generates second positioning information items. The processor may be configured to buffer the second positioning information items generated by the second positioning system and to determine a position estimation for the device based on the first positioning information items generated by the first positioning system. The processor may be configured to detect a degradation in a quality of the first positioning system. The processor may be configured to, in response to detecting the degradation in the quality of the first positioning system, determine the position estimation for the device based at least in part on at least one of the buffered second positioning information items generated by the second positioning system.
