Abstract: Through comparising the advantages and disadvantages of sensor-related modeling standards: IEEE 1451,ECHONET and SensorML,a general remote-sensing satellite sensor modeling approach based on SensorML and ISO 19130 is proposed.The procedures of the proposed approach include sensor parameters analysis,dictionary definition,system modeling,process modeling,process chain modeling,model validation and model rectification.The modeling tool,namely SensorModel,is designed and implemented using.NET framework based on the proposed approach.The SPOT-5 satellite platform modeling was used to test the feasibilities of the proposed approach.
