Mehlam tells his story of growing up in Texas as a Pakistani-American and part of the Dawoodi Bohra Muslim community, and how he navigated his senses of belonging and identity. He shares formative experiences of grappling with grief and mental health at a young age. He discusses involvement, such as high school debate club and college participation in United Students Against Sweatshops, that shaped his worldview and commitment to social justice. Mehlam also talks about his involvement in the Palestinian Solidarity Committee and his current work with Family Eldercare. Content Warning: The following interview contains sensitive material. Please note that the interview includes description of suicidal ideation and psychiatric hospitalization. These subjects will be discussed at 23:01-24:29 (in the transcript p. 6).Item Receiver-Autonomous Spoofing Detection: Experimental Results of a Multi-antenna Receiver Defense Against a Portable Civil GPS Spoofer(2011) Montgomery, Paul Y.In this work we demonstrate the use of a dual antenna receiver that employs a receiver-autonomous angle-ofarrival spoofing countermeasure. This defense is conjectured to be effective against all but the most sophisticated spoofing attempts. The technique is based on observation of L1 carrier differences between multiple antennas referenced to a common oscillator. We first employ a moderately sophisticated spoofer to "fool" a single-antenna civil receiver. We then deploy the same attack after augmenting the receiver with an additional antenna and with receiver-autonomous spoofdetection software. The work discusses the experimental results together with various issues related to sensitivity, probability of false alarm, impact of carrier multipath, line-bias-calibration, and physical setup and security. We suggest that this work is important to the community as it provides experimental validation of a low-cost technique for receiver-autonomous spoofing detection. Furthermore, the technique, when combined with physical security of the antenna installation, provides a strong defense against even a sophisticated attack. The receiver employed is an L1-only civil GPS receiver with multiple antenna capability. The GPS chipset employed is the venerable GP2015/GP2021 that has been freely available for over a decade. As such, this receiver is representative of many civil receivers in use today for a variety of applications. Multiple antennas are enabled either through multiple independent RF front ends and correlators or via antenna multiplexing into a single RF front end and correlator bank.
