چکیده

The FAA Alternative Position Navigation and Timing effort is developing technologies to provide navigation service capable of sustaining operations in the event of the loss of Global Navigation Satellite Systems (GNSS). APNT will utilize existing ground infrastructure to support this capability. One effort is to examine the use of the Automatic Dependent Surveillance Broadcast (ADS-B) ground infrastructure for ranging. This paper examines the use the two transmitted ADS-B signals: 1) 1090 MHz Mode S Extended Squitter (Mode ES) and Universal Access Transceiver (UAT). It uses the transmitted, onair signal to examine multipath, ranging and timing performance. Keywords—APNT; UAT; Mode S ES

Exposure to radiofrequency wave (RFW) generated by a base transceiver stations (BTS) antenna model affects learning and memory in female more than male rats

Background: Exposure to electromagnetic radiation may impair memory. This study was conducted to evaluate the effect of radiofrequency wave (hereafter referred to as RFW) on passive avoidance learning and memory in healthy males and females. Materials and Methods: Ten adult male and ten female Sprague-Dawley rats (230±20 gr) were randomly divided into four groups including two control groups (o...
