Like the GPS units in many automobiles today, a simple receiver and some processing power is all that is needed for accurate navigation. But, what if the GPS satellites suddenly became unavailable due to malfunction, enemy action or simple interference, such as driving into a tunnel? Unavailability of GPS would be inconvenient for drivers on the road, but could be disastrous for military missions.

Enabling the Next Generation of GPS Technology with Supercorrelation with Dr Ramsey Faragher
Royal Institute of Navigation. Focal Point Positioning have developed a new method for processing GNSS radio signals called Supercorrelation which dramatically improves the performance of the earliest stage of radio processing. The software update removes multipath interference at the correlator level, and provides the ability to determine signal arrival angle without adding any new hardware to a standard GNSS device. In this webinar Dr Ramsey Faragher, Founder/CEO of FocalPoint will explain how the technology works, will cover some of the challenges that FocalPoint have overcome in deploying it on very low cost platforms, and will show off the new capabilities that it unlocks.

GRCon20 - Software defined radio based Global Navigation Satellite System real time spoofing....
Software defined radio based Global Navigation Satellite System real time spoofing detection and cancellation Presented by Jean-Michel Friedt,, D. Rabus and G. Goavec-Merou at GNU Radio Conference 2020 https://gnuradio.org/grcon20 Global Navigation Satellite Systems (GNSS) -- most significantly the Global Positioning System (GPS) -- have become ubiquitous to most daily activities, from positioning and navigation to long range time synchronization or distributed energy production ("smart grid"). While initially developed as a military system hardly accessible to civilians, the advent of Software Defined Radio jamming and spoofing capabilities emphasize the low security of GNSS weak signals emitted from satellites orbiting the Earth 20000 km away. While a properly spoofing signal cannot be detected after a consumer-grade receiver has decoded the radiofrequency signal, addressing at the radiofrequency wave level the signal integrity provides the solution of identifying spoofing with all satellites appearing at the same direction of arrival. This classical beamforming analysis -- Controlled Reception Pattern Antenna (CRPA) with multiple antenna reception and phase analysis -- is demonstrated using commercial, off the shelf software defined radio platform receivers (Ettus Research B210) running the real-time GNSS decoder gnss-sdr based on GNU Radio running on embedded boards such as the Raspberry Pi4.

PULP-DroNet -- Autonomous Artificial Intelligence-powered Nano-Drone
PULP-DroNet is a Deep Learning-powered visual navigation engine that enables autonomous navigation of a pocket-size quadrotor in a previously unseen environment.
Thanks to PULP-DroNet the nano-drone can explore the environment, avoiding collisions also with dynamic obstacles, in complete autonomy -- no human operator, no ad-hoc external signals, and no remote laptop! This means that all the complex computations are done directly aboard the vehicle and very fast. The visual navigation engine is composed of both a software and a hardware part. The former is based on the previous DroNet [1] project developed by the RPG [2] from the University of Zürich (UZH). DroNet is a shallow convolutional neural network (CNN) which has been used to control a standard-size quadrotor in a set of environments via remote computation. The hardware soul of PULP-DroNet is embodied by the PULP-Shield an ultra-low power visual navigation module featuring a Parallel Ultra-Low-Power (PULP) GAP8 System-on-Chip (SoC) from GreenWaves Technologies [3], an ultra-low power camera, and off-chip Flash/DRAM memory; the shield is designed as a pluggable PCB for the Crazyflie 2.0 [4] nano-drone. Then, we developed a general methodology for deploying state-of-the-art Deep Learning algorithms on top of ultra-low power embedded computation nodes, like a miniaturized drone. Our novel methodology allowed us first to deploy DroNet on the PULP-Shield, and then demonstrating how it enables the execution the CNN on board the CrazyFlie 2.0 within only 64-284mW and with a throughput of 6-18 frame-per-second! Finally, we field-prove our methodology presenting a closed-loop fully working demonstration of vision-driven autonomous navigation relying only on onboard resources, and within an ultra-low power budget. We release here, as open source, all our code, hardware designs, datasets, and trained networks. Reference: D. Palossi, F. Conti, and L.

Dr. Carles Fernandez: An Open Source Global Navigation Satellite Systems Software-Defined Receiver
Software Defined Radio Academy GNSS-SDR (see https://gnss-sdr.org) is an open source, software-defined Global Navigation Satellite Systems (GNSS) receiver. This software application takes care of all the digital signal processing chain (from the output of the Analog-to-Digital Converter of a radio-frequency front-end, or from raw sam- ples stored in a file), performing signal acquisition and tracking of the available satellite signals, decoding the navigation message and computing the observables needed by positioning algorithms, which ultimately compute the navigation solution. Several outputs are provided in standard formats, including RINEX observation and navigation files, RTCM-104 v3.2 message streaming via TCP/IP and NMEA-0183, as well as KML, GeoJSON, and GPX files for Geographic Information Systems, map representation and Earth browsers. Currently, the software is able to process GLONASS L1 C/A, GPS L1 C/A, Galileo E1b/c, BeiDou B1I, BeiDou B3I, GLONASS L2 C/A, GPS L2C, GPS L5 and Galileo E5a signals, in all possible combinations, including multi-constellation and multi-frequency configurations. The software leverages on the GNU Radio framework, inheriting multithreading scheduling and a modular, scalable architecture. The software is designed to facilitate the inclusion of new signal processing techniques, offering an easy way to measure their impact in the overall receiver performance under fair conditions, as well as the expansion to other signals.

Typically, the performance of measurement devices is limited by deleterious effects such as thermal noise and vibration. Notable exceptions are atomic clocks, which operate very near their fundamental limits. Driving devices to their physical limits will open new application spaces critical to future DoD systems. Indeed, many defense-critical applications already require exceptionally precise time and frequency standards enabled only by atomic clocks. The Global Positioning System (GPS) and the internet are two key examples. Measurement systems based on atomic physics benefit from the exquisite properties of the atom. Among these are (a) precise frequency transitions, (b) the ability to initialize, control, and readout the atomic state and (c) environmental isolation. In addition, atomic properties are absolute, and do not “drift” over time. In this sense, atoms are self-calibrated, making them ideal for precision sensing.

IT'S NOT REAL! Physicists PROVE Time Does NOT Exist
We, humans, are fascinated with the idea of traveling back or ahead in time. Time Travel Machines and Devices have been a staple for a lot of science fiction and even fantasy stories catering to our desire to either change something in the past to make our lives better or just skip ahead in time to find out if life gets better on its own in the future. Ever wonder why we may never develop a Time Machine? Because Time probably doesn’t even EXIST! Welcome to Factnomenal, and today let’s find out why some physicists insist that TIME exists only in our heads.
