| Abstract: | Observability requirements for the multiple moving observers bearings-only location system are studied. The problem of multiple moving observers bearings-only system is transformed into the problem of special single moving observer by the motion equivalent. Using pseudo-linear estimate equation, some un-observability conditions for the system are derived, and further analysis reveals a previous unknown condition under which the system remains unobservable. |
