Brits largely endured frigid temperatures in September – but globally, the story was quite different. Last month was the second-hottest September on record, the EU's climate change programme has revealed. The global average air temperature for September 2024 was 61.1 F (16.17 C), which is 1.31 F (0.73 C) above the September average. What's more, it's just shy of the record set by September 2023 – 61.4 F (16.38 C). Worryingly, experts point to human-cased greenhouse gas emissions as the cause for this latest temperature'anomaly'.

Multipath is among the major sources of errors in precise positioning using GPS and continues to be extensively studied. Two Fast Fourier Transform (FFT)-based detectors are presented in this paper as GPS multipath detection techniques. The detectors are formulated as binary hypothesis tests under the assumption that the multipath exists for a sufficient time frame that allows its detection based on the quadrature arm of the coherent Early-minus-Late discriminator (Q EmL) for a scalar tracking loop (STL) or on the quadrature (Q EmL) and/or in-phase arm (I EmL) for a vector tracking loop (VTL), using an observation window of N samples. Performance analysis of the suggested detectors is done on multipath signal data acquired from the multipath environment simulator developed by the German Aerospace Centre (DLR) as well as on multipath data from real GPS signals. Application of the detection tests to correlator outputs of scalar and vector tracking loops shows that they may be used to exclude multipath contaminated satellites from the navigation solution. These detection techniques can be extended to other Global Navigation Satellite Systems (GNSS) such as GLONASS, Galileo and Beidou.

Former VP Joe Biden will speak at the South by Southwest conference highlighting his cancer moonshot. Guests pose for a #GettyGotMe photo during SXSW 2016 in Austin, Texas. They'll be no lack of controversial issues to dissect at this year's SXSW Conference & Festivals, which begins Friday and runs through Mar. And more so than in past years, this year's massive gathering of tech, film and music enthusiasts – usually equated with tech innovation and startups – will have a stronger-than-ever focus on politics. Former Vice President Joe Biden and CNN's Van Jones are scheduled to speak.

Organizers of South By Southwest said Monday, March 6, that Biden will give a speech on Sunday, March 12 at the festival in Austin, Texas, about about his cancer-fighting initiative.
