The North Atlantic is increasingly developing into the main trade route of the age. Shipping, the pioneer along this highway of commerce, in the past decade has been joined by air traffic displaying a striking growth rate. Not only is the number of aircraft simultaneously plying the Atlantic routes constantly on the increase, but also the volume of passengers and freight transported on each flight. The question, whether such flow of traffic in the air and on water could be dealt with in future with the safety to which it is entitled, has led to world-wide discussions over the past few years concerning the necessity for an air traffic surveillance system for the North Atlantic area. A further question, whether one should not include also sea traffic in such a system suggested itself. The initiative for holding such discussions naturally proceeded less from air and shipping undertakings, but rather from those committees who are entrusted in supervising the safety in the conduct of man and merchandise.

Abstract The concept of e-Navigation is to unify activities for the collection, integration, exchange, presentation and analysis of information on vessels and in coastal services through electronic technologies to improve the navigation safety, and the quality and efficiency of the relevant services.The generalized analysis of the obtained data is used to determine the appropriate actions in the prevailing conditions, to improve the process of the vessel’s transition from berth to berth (in ports of departure and destination) and the corresponding services that ensure the safety of navigation, environmental protection, information exchange between intelligent transport systems.The basis for fulfilling the assigned tasks are three basic components of e-Navigation: vessel systems; coastal and satellite systems; communication infrastructure. The purpose of the paper is the possibility of applying broadband radio communications for unmanned navigation in the coastal zone. The research object is the analysis of broadband communication systems; the subject is the assumed range of the WiMAX radio communication zone. EMC Planner 1.1_170328 is used to simulate the anticipated WiMAX radio zone.

Intelligent Monitoring and Recording System (IMRS) is being used in many fields like Aviation Traffic control, Transportation, Real Estate, Medical Science and more. One of the IMRS system is Vehicle Traffic on roads. Intelligent Transportation System (ITS) is an important part of IMRS which is used to collect and analyze the statistics related to the Vehicle Traffic. This paper gives an insight of the ITS by using open source tools which are easy to implement. Large datasets of vehicle information has been taken into the experiments of this paper. Utilizing different digital image processing techniques, we have extracted vehicle number from the number plates. Technically, this paper is based on ITS in which two main features has been designed, first is to store Vehicle related information in the Hbase. Another feature is to retrieve the data, on the basis of the vehicle number, from the database giving the details of the vehicle including Road Tax, Insurance and Stolen status and also inform the possessor about the invalidity of Insurance, Registration Certificate (RC) and License. Time and accuracy are two challenges in performing the IMRS in a real life scenario. It has been observed that the proposed system is 27% faster than Automatic Number Plate Recognition (ANPR) on the basis of two comparative parameters i.e. Precision and Recall

In Air Traffic Control (ATC), aircraft altitude data is used to keep an aircraft within a specified minimum distance vertically from other aircraft, terrain and obstacles to reduce the risk of collision. Two types of altitude data are downlinked by radar; actual flight level (Mode C) and selected altitude (Mode S). Flight level indicates pressure altitude, also known as barometric altitude used by controllers for aircraft vertical separation. ‘Selected altitude’ presents intent only, and hence cannot be used for separation purposes. The emergence of Global Navigation Satellite Systems (GNSSs) has enabled geometric altitude on board and to the controllers via the Automatic Dependent Surveillance-Broadcast (ADS-B) system. In addition, ADS-B provides quality indicator parameters for both geometric and barometric altitudes. Availability of this information will enhance Air Traffic Management (ATM) safety. For example, incidents due to Altimetry System Error (ASE) may potentially be avoided with this information. This work investigates the use and availability of these parameters and studies the characteristics of geometric and barometric data and other data that complement the use of these altitude data in the ADS-B messages. Findings show that only 8·7% of the altitude deviation is < 245 feet (which is a requirement of the International Civil Aviation Organization (ICAO) to operate in Reduced Vertical Separation Minimum (RVSM) airspace). This work provides an alert/guidance for future ground or airborne applications that may utilise geometric/barometric altitude data from ADS-B, to include safety barriers that can be found or analysed from the ADS-B messages itself to ensure ATM safety.
