Title:
位置決定におけるアンビギティーの解決方法
Document Type and Number:
Japanese Patent JP5129356
Kind Code:
B2
Abstract:
Various heuristics techniques for resolving ambiguity in location determination in environments with or without noise. A final location determination solution may be determined from a set of ambiguous location determination solutions by using clock temporal bias value, by using consistency information of ranging signal order such as the time of arrival or the received power level of the ranging signals, by using the distances to the sources or by using a discriminator function related to noise to select the final location determination solution from a plurality of ambiguous location determination solutions. The main advantage of the heuristic approaches is that redundant measurements are not required for location determination solution disambiguation.
