- 摘要：
- A method and system to confirm co-location of multiple devices within a geographic area, while filtering spurious alarms, is provided. An example method comprises processing first GPS data obtained from a first GPS sensor and second GPS data obtained from a second GPS sensor. A sensing data evaluator compares a sensing error from the first GPS data and a sensing error from the second GPS data. Based on the result of the comparing, the sensing data evaluator determines whether the sensing errors are to be ignored. An approach where an alarm that otherwise would be generated is disabled or canceled may be termed as filtering spurious alarms.
