  • Technical Paper
  • 2019-28-2516
To be published on 2019-11-21 by SAE International in United States
In this paper we propose the snow mobility vehicle in order increase the mobility and decrease the risk of accidents for carry food and medicines on snow bounded areas using unmanned tracked vehicle called as snowmobii 2.0. Our unmanned tracked vehicle can transport Food/medicines as well as Defence in snow bounded areas. This unmanned robot can run in loose as well as hard snow due to it have specific featured technology in base wheel(track wheel system) such as hub with outer seals that improve its durability. The proposed snow mobility vehicle is consist of many sophisticated-designed systems such as navigation system, obstacle detection system, communication system, temperature sensing system. Snowmobii 2.0 is easy to get command and enable significant reduction in losses of many solder’s precious lives due to unavailability of food and medicines at that place. An unmanned tracked vehicle (snowmobii 2.0) is actively being developed for military use to perform various task like mobility on snow surface, carry food/medicines, defence etc.Predominantly this vehicle is used to replace human movement at hazardous place.

Critical Communications Break Out of the Analog Mold

Aerospace & Defense Technology: August 2019

  • Magazine Article
  • 19AERP08_05
Published 2019-08-01 by SAE International in United States

Military and public safety communications increase digital and data capabilities without sacrificing reliability or interoperability.

Once firmly rooted in its analog origins, critical communications is now steadily evolving to provide enhanced situational awareness. The latest public safety and military communications (MilCom) radios are more versatile and reliable, supporting ad-hoc networks to improve or enable connectivity. With higher-data-rate capabilities, critical communications solutions can send and receive high-resolution images, videos, and other types of data-intensive content. At the same time, they provide higher-quality voice communications while maintaining security. To ensure communications and interoperability, they still can support analog communications as a failsafe. These myriad capabilities are possible through the ongoing adoption of new technologies, ranging from digital public safety standards and modulation formats, to technologies like wireless local area networking (WLAN) and Long Term Evolution (LTE).

Communication Transceivers Qualification Requirements - LIN

Vehicle Architecture For Data Communications Standards
  • Ground Vehicle Standard
  • J2962/1_201907
  • Current
Published 2019-07-18 by SAE International in United States

This document covers the requirements for transceiver qualification. Requirements stated in this document will provide a minimum standard level of performance for the LIN transceiver block in the IC to which all compatible transceivers shall be designed. No other features in the IC are tested or qualified as part of this recommended practice. This will assure robust serial data communication among all connected devices regardless of supplier.

Converting ATIS Message Standards From ASN.1 to XML

V2X Core Technical Committee
  • Ground Vehicle Standard
  • J2630_201907
  • Current
Published 2019-07-12 by SAE International in United States

This SAE Standard presents a set of rules for transforming an Abstract Syntax Notation (ASN.1) message set definition into an eXtensible Markup Language (XML) schema. The result is intended to be a stand-alone XML Schema that is fully consistent with an existing ASN.1 information model. This is a different goal from other related work by other standards bodies developing a set of XML encoding rules for ASN.1 or ASN.1 encodings for XML Schema. These rules were initially developed in order to produce an XML schema for the SAE ATIS standard. While other standards may also choose to use these rules, the rules may not be applicable for all environments.

 

Integrated Silicon Photonic Switch Demonstrates Lowest Signal Loss Ever in High-Speed Data Transmission

  • Magazine Article
  • TBMG-34770
Published 2019-07-01 by Tech Briefs Media Group in United States

Experimental photonic switches developed at UC Berkeley have shown promise toward the goal of fully optical, high-capacity switching for future high-speed data transmission networks. The switch developed and tested for this research demonstrated capabilities not seen before in photonic switches. Key to this success, is the scale-up of a 240 × 240 integrated silicon photonic switch. The device is so-named because it accepts 240 optical communication input channels and sends them into 240 output channels.

 

Dedicated Short Range Communications (DSRC) Performance Requirements for V2V Safety Awareness™ Set

V2X Vehicular Applications Technical Committee
  • Ground Vehicle Standard
  • J2945/2S_201907
  • Current
Published 2019-07-01 by SAE International in United States

This Abstract Syntax Notation (ASN.1) File is the precise source code used for SAE International Standard J2945/2. As part of an international treaty, all US ITS standards are expressed in "ASN.1 syntax". ASN.1 Syntax is used to define the messages or "ASN specifications". Using the ASN.1 specification, a compiler tool produces the ASN library which will then be used to produce encodings (The J2945/2 message set uses UPER encoding). The library is a set of many separate files that collectively implement the encoding and decoding of the standard. The library is then used by any application (along with the additional logic of that application) to manage the messages. The chosen ASN tool is used to produce a new copy of the library when changes are made, and it is then linked to the final application being developed. The ASN library manages many of the details associated with ASN syntax, allowing for subtle manipulation to make the best advantage of the encoding style.

 

Comparison of GATS Messages to SAE ATIS Standards

V2X Core Technical Committee
  • Ground Vehicle Standard
  • J2539_201906
  • Current
Published 2019-06-11 by SAE International in United States

This SAE Information Report provides a comparative summary between the various messages found in the SAE ATIS standards work (notably SAE J2313, J2353, J2354, J2369 and J2374) and that found in the GATS standard (Global Automotive Telematics Standard). GATS is a message set meant to be deployed on mobile phone systems based on the GSM (Global System for Mobile Communication) phone system which is being deployed in European markets and which the SAE may need to harmonize with as part of the World Standards activities of TC204. This document provides an overview of the various types of supported messages and how they compare with US terms and messages. Some selected features of the GATS work are recommended for assimilation into the next revision of ATIS standards. No attempt at determining a U.S. policy in this regard is provided. This document seeks to provide the reader familiar with SAE ATIS with a high level overview of technical knowledge of the GATS approach in similar areas.
