While this may be an accepted fact for most members, it came to me with a sense of surprise and disappointment. The fact that military vehicular communication problems and experiences are so poorly represented at our national conferences has never ceased to be viewed by me with a feeling of regret. Surely the similarities, between military and civilian vehicular communications, far outnumber the differences.","PeriodicalId":263631,"journal":{"name":"IRE Transactions on Vehicular Communications","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1962-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128157230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Field and laboratory tests conducted to date indicate that the proposed technical standards can be successfully implemented in closely controlled test systems. Some significant problems may arise in actual \"user\" systems, however, if transmitters and receivers are not properly netted and held to a close RF channel tolerance. Considerable attention must be given to the various factors which determine the amount of receiver performance degradation experienced, if successful implementation of \"same area\" adjacent channel operation is to be achieved. Existing 450 mc equipment of recent manufacture should provide adequate performance in most systems until the 25 kc split channels are assigned to new users in the same area.","PeriodicalId":263631,"journal":{"name":"IRE Transactions on Vehicular Communications","volume":"600 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1961-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116294911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such systems perform most of the operations which would be performed manually were it possible for a man to enter the hazardous area. Examples of hostile environments include space, the ocean, nuclear laboratories, and numerous others. A simple trinary coding command system has proved quite practical and is capable of commanding mobile remote systems having 50 or more degrees of freedom. Conventional closed-circuit television systems may be used for driving and steering remotely-controlled vehicles and for accomplishing manipulative tasks. Two or more such cameras are highly desirable for obtaining good spatial perception. Examples of remotely-controlled systems for hostile environments include the Hughes Mark II Mobot system for nuclear hot laboratories, the RUM (Remote Underwater Manipulator) built by Scripps Institute of Oceanography for scientific and military operation in the depths of the ocean, and a variety of outdoor remotely-controlled vehicles designed and operated by Engineer Research and Development Laboratory at Fort Belvoir, Virginia, and by Air Force Special Weapons Center in Albuquerque, New Mexico.","PeriodicalId":263631,"journal":{"name":"IRE Transactions on Vehicular Communications","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1961-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125463215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using only a narrow-band width, it can be used for transmission of data (teletype, telemetry, canned messages, facimile, etc.) over distances of upwards to 500 miles, using relatively low power transmitters and simple antenna systems. It will provide a useful link in the radio communication systems for many government agencies, both military and non-defense.
