“…In a previous study [1], measurements of spurious emissions in aircraft radio bands of ten different active tags showed that many have higher peak emission levels than several RTCA/DO-160 aircraft equipment emission limits. In one case, the peak emissions exceeded the limits in the glideslope (GS) band by as much as 35 dB.…”

“…With the tag's peak emission level known from a previous effort [1], a significant part of the current effort was to determine the interference threshold for a GS receiver. A desired GS signal and an interference signal with a varying level were injected into the receiver's antenna port.…”

“…At this rate, the transmission duty cycle is about 0.06 percent (percent duty cycle = 100 *37 * 0.01 msec / 610 msec). The tag's peak emission data were previously measured in a reverberation chamber and reported [1]. The data included the measurement results for many aircraft radio bands.…”

Abstract-NASA aeronautical programs require integrated vehicle health monitoring (IVHM) to ensure the safety of the crew and the vehicles. Future IVHM sensors need to be small, light weight, inexpensive, and wireless. Surface acoustic wave (SAW) technology meets all of these constraints. In addition it operates in harsh environments and over wide temperature ranges, and it is inherently radiation hardened. This paper presents a survey of research opportunities for universities and industry to develop new sensors that address anticipated IVHM needs for aerospace vehicles. Potential applications of passive wireless SAW sensors from ground testing to high altitude aircraft operations are presented, along with some of the challenges and issues of the technology.

The use of RFID tags to identify and track cargo is already common, and expected to grow. Inevitably, many such tags will be used on air freight shipments. Therefore, the effects of such RFID tags on common avionics is an issue of concern to owners, operators, regulators and the traveling public. A recent study by NASA Langley Research Center identified a particular RFID device having a relatively high level of emissions in the 328.6-335.4 MHz band associated with the Instrument Landing System Glide Slope function.This paper summarizes a small NASAsupported study performed by the technical staff of the Honeywell Aerospace Advanced Technology organization to estimate the effects of the measured emission levels and signal structure on the Glide Slope guidance function. The paper includes a derivation of the guidance error variance, a model for accommodating RFID duty cycle, and application of the simple analysis recommended by RTCA/DO-294B. The conclusion is that, under likely operating conditions, low duty cycle RFID tags such as the specific family identified by NASA should have no meaningful effect on GS operation. Extrapolations to other narrowband receiver systems reach similar conclusions.
