Do So

Recent years have seen a number of proposals for the use of satellites by aviation, either for navigation or for air/ground communications and the question is often asked why commercial aviation, one of the most technologically advanced industries in the world, is so reluctant to utilize satellite techniques. So far, these proposals have not succeeded because they failed to satisfy a genuine operational requirement and were not, by any standard, cost effective. Up to the present time the systems which have evolved over the years have performed the required tasks reasonably adequately and would appear, given the normal process of development, to be able to continue to do so for some years to come.

Satellite Navigation Systems

The industry of civil aviation is developing in a fast manner to occupy the increasing needs for a fast, safe and comfortable transportation. To achieve these needs, some effective programs, plans, and systems designs are required. The current reliable aircraft navigation and landing systems have relatively a low level of accuracy especially in aircraft landing stage. The best landing category could be achieved requires a runway visual range up to 50 meters and automatic landing system is not in operation yet all over the world. Aircraft navigates using Radar, Radio and Satellite navigation systems. The Federal Aviation Administration (FAA) plans to replace legacy navigation systems with satellite based navigation technology. Currently, the Global Positioning System (GPS) and its augmentations is the main satellite navigation system used all over the world for air navigation applications. The development of aircraft navigation has been performed with the enhancement of GPS augmentation systems. In this paper, aircraft navigation systems and techniques will be presented in this paper to evaluate the integrity and reliability of each system, and to make a comparison among these systems according to accuracy, integrity and availability.

The Cost

This paper is based on the results of the ‘GNSS Support Task’ study for the European Commission, DGXIII. It summarises the results of the cost benefit analysis in terms of coverage, accuracy and safety requirements for different types of user and describes the most cost-effective GNSS 2 architecture. These analyses also assume that the overall system is layered into wide area, regional and local systems. The future planning of satellite navigation is essentially driven by the wide area requirements and ensuring that these are global and seamless. There is some flexibility in coverage and accuracy for a wide area system in that it can be augmented regionally or locally if required, but it must provide the highest level of safety required. The paper approaches the architecture for a future navigation system from this safety aspect. An analysis of the chosen architecture shows that the required safety performance can be met. An implementation plan is described which allows a gradual evolution from the first system to be realized for safety critical operations to a fully civilian owned and operated system.

Maritime Community

When the satellite era commenced more than a quarter of a century ago, one could hardly foresee the world wide revolution it heralded in the development of aids to navigation for merchant shipping. However, early investigations into the possible application of satellites to maritime needs led to an understanding of the powerful potential of satellite techniques for navigation. It became clear that if the international maritime community was really interested in a global all-weather, high-precision and commercially viable navigation system; such a system could only be satellite-based. This is evident from the situation that has recently arisen in IMO, where after exhaustive discussion on the mandatory carriage of electronic position-fixing equipment on ships in designated areas, the organization could not express a preference for any particular aid, until it was decided that efforts should be made to develop a global satellite navigation system capable of meeting a new standard of navigational accuracy. Moreover, in preparing the navigational accuracy standard, account was taken of experience gained with existing satellite navigation systems.

Insufficient Number

Nowadays majority of navigation methods, used in unmanned flying vehicles, are based on satellite navigation systems, such as GPS or GLONASS, or are amplified with them. But hardware, that uses such systems, can’t work in difficult conditions, for example causes by relief: with insufficient number of satellites or at low satellite signal. Satellite navigation systems are vulnerable for methods of radio defense: satellite signal can be deadened or replaced. That is why such systems usage is unacceptable while critical missions during military operations, emergency or reconnaissance. The article briefly describes components used for building alternative satellite-free navigation systems for flying vehicles. For each component its purpose and brief description of working principle are given, advantages and disadvantages are considered.
