High Altitude Platform System Airship for Telecommunication and Border Monitoring Design and Physical Model

Henri Coanda Labs LLC-Michele Trancossi
  • Technical Paper
  • 2020-01-0044
Published 2020-03-10 by SAE International in United States
This paper presents an accurate analysis of an innovative high altitude platform with an unconventional ellipsoidal shape during the most critical operation. The airship is designed accordingly to the specifications, which have been analyzed in terms of the required CONOPS (Concepts of Operations) which are associated with the proposed High Altitude Pseudo-Satellite (HAPS) technology and special operations and to analyze the operational scenarios. An innovative cruiser feeder system is defined and studied. The CONOPS includes communications relays, support of intelligence, surveillance, target acquisition monitor “mobile targets”, and reconnaissance, including long-range ISTAR missions performed by the feeder, combining satellite vision and HAPS vision for a forest fire, disasters, naval accidents, maritime and ground borders. The paper realizes a multidisciplinary analysis that allows creating the design of the HAPS, referring to both cruiser and feeder in different operative scenarios. It is expected to produce the preliminary basis for a future digital twin based design to generate the best possible configuration by mean of implementing multiphysics simulations. Structured object-oriented design processes involve developing several different system models and…

Compact Antenna Enables Communication Where Radios Fail

  • Magazine Article
  • TBMG-35157
Published 2019-09-01 by Tech Briefs Media Group in United States

A pocket-sized antenna was developed that could enable mobile communication in situations where conventional radios don’t work such as underwater, through the ground, and over very long distances through air. The device emits very low frequency (VLF) radiation with wavelengths of tens to hundreds of miles. These waves travel long distances beyond the horizon and can penetrate environments that would block radio waves with shorter wavelengths. While today’s most powerful VLF technology requires gigantic emitters, this antenna is only four inches tall, so it could potentially be used for tasks that demand high mobility including rescue and defense missions.

Assessment of Automotive Environmental Noise on Mobile Phone Hands-Free Call Quality

FEV North America, Inc.-Jeffrey Pruetz, Channing Watson, Todd Tousignant, Kiran Govindswamy
Published 2019-06-05 by SAE International in United States
Environmental noises such as wind, road, powertrain, and HVAC noise are important aspects to consider when implementing a hands-free terminal for mobile phone calling from within a car. Traditionally, these environmental noises have been exclusively considered for driver comfort; however, with the introduction of the hands-free terminals (HFT) and increasing consumer demand relative to mobile phone call quality, a broader implication of high background noise levels should be considered. HFT algorithm development and implementation can and does provide a high level of background noise suppression to mitigate these concerns, but this is often done at the expense of computational power and cumulative delay during a phone call. The more advantageous solution would be to address the problem from a source and path perspective with emphasis on reduction of noise in the frequency bands which most influence call quality performance. The assessments shown throughout this paper establish a sensitivity of HFT call quality to background noise levels based on industry-standard metrics, including those defined by International Telecommunication Union (ITU) standards. These assessments were established based on…

Single-Photon Detector for Potential Encryption and Sensing

  • Magazine Article
  • TBMG-34600
Published 2019-06-01 by Tech Briefs Media Group in United States

Light is widely used for communications, carrying phone conversations and video signals through fiber optic cables around the world in pulses composed of many photons. Single photons are the weakest signal that can be transmitted and they have a wide range of applications including implementing an encryption technique called quantum key distribution and creating high-resolution maps. Single photons of light typically have very little energy, making them difficult to detect.

New Device Widens Light Beams by 400 Times

  • Magazine Article
  • TBMG-33564
Published 2019-01-01 by Tech Briefs Media Group in United States

By using light waves instead of electric current to transmit data, photonic chips — circuits for light — have advanced fundamental research in many areas from timekeeping to telecommunications. But for many applications, the narrow beams of light that traverse these circuits must be substantially widened in order to connect with larger, off-chip systems. Wider light beams could boost the speed and sensitivity of medical imaging and diagnostic procedures, security systems that detect trace amounts of toxic or volatile chemicals and devices that depend on the analysis of large groupings of atoms.

New Laser for Improving Telecommunications and Computing

  • Magazine Article
  • TBMG-33389
Published 2018-12-01 by Tech Briefs Media Group in United States

The first laser based on the wave physics phenomenon called bound states in the continuum (BIC) has been developed. The technology could revolutionize the development of surface lasers, making them more compact and energy-efficient for communications and computing applications. The BIC lasers could also be developed as high-power lasers for industrial and defense applications.

Buckendale Lecture Series: Transformational Technologies Reshaping Transportation—A Government Perspective

Michigan Dept. of Transportation-Kirk Steudle, Niles Annelin
Published 2018-09-01 by SAE International in United States
Transportation departments are under-going a dramatic transformation, shifting from organizations focused primarily on building roads to a focus on mobility for all users. The transformation is the result of rapidly advancing autonomous vehicle technology and personal telecommunication technology. These technologies provide the opportunity to dramatically improve safety, mobility, and economic opportunity for society and industry. Future generations of engineers and other transportation professionals have the opportunity to be part of that societal change. This paper will focus on the technologies state DOT’s and the private sector are researching, developing, and deploying to promote the future of mobility and improved efficiency for commercial trucking through advancements in truck platooning, self-driving long-haul trucking, and automated last mile distribution networks.Additionally, the paper will explore the trends likely to affect the automotive industry, such as deployments of signal phase and timing technology, marketing mobility as a service, vehicle to vehicle communication, and vehicle to infrastructure communication. This paper will also cover the relevance of freight planning to the industry as well has how mobility is changing across society and…

Faster Photons Could Make Data Totally Secure

  • Magazine Article
  • TBMG-32839
Published 2018-09-01 by Tech Briefs Media Group in United States

Transferring data using light passed along fiber optic cables has become increasingly common over the past decades, but each pulse currently contains millions of photons. That means that in principle, a portion of these could be intercepted without detection. Secure data is already encrypted, but if an eavesdropper was able to intercept the signals containing details of the code, in theory they could access and decode the rest of the message.
