// Generally speaking, most passive HF and UHF RFID systems do not provide location accuracythey tell you that a tag has been read by a specific reader. // You might have better luck with a laser scanner affixed to the aircraft. |

//Generally speaking, most passive HF and UHF RFID systems do not provide location accuracy//All right then, use three readers. |

If the RFID tags RFID is unique, why would you need to locate the tag again? If it reports, it can only report from the location it was attached to. |

Yo pilot, this is RFID Tag B34776504.56.9.33, calling from the left outboard elevon. Its getting hot here and we have a problem. |

How much more location data do you need? If they are passive, whats needed is an AirEye linked to that RFID that gives a visual of the problem area. Could the RFID be passive only until certain conditions are met and then activate and report? Damage, temperature, barometric reading, etc. |

// If the RFID tags RFID is unique, why would you need to locate the tag again?// The idea is to perform regular polling, say once every 5 seconds, to identify their locations. If, say, there's a tail strike and some of the tail scraped off onto the runway those bits will no longer be reporting in. Or if the rudder moves left those bits will report in left of where they used to be.
//Could the RFID be passive only until certain conditions are met and then activate and report?//RFID tags are extremely simple little bits of antenna. They're not active computers. All they can do is be readable for ID and, if you have the right antenna setup, location. The RFID does not call in, it's scanned for. |

How close do you have to be with the scanner to get the data off the chip? How would you do it? |
|
|
Even without location accuracy, given the limited range of rfid tags, it would at least tell you if the bit is missing. |
|
|
That being said, I suspect cameras would be a better reporting tool. A camera visible grid printed on the aircraft would allows easy tracking with minimal image processing. |
