The view is taken in this paper that an automatic navigation system should be capable of weighing up data and issuing instructions, in the same manner as a human navigator. Conventional information tends to offer static rather than dynamic data.It is suggested that there are several stages of development towards completely automatic navigation: (i) a dynamic interpretation of the existing navigational situation, (ii) the automatic prediction of future situations, (iii) automatic navigational advice, (iv) automatic control of a ship under the supervision of a navigator. Such control would not take care of all situations but would be particularly suited to some; a list of the information likely to be required for presentation is given.For entirely automatic navigation to be feasible, the whole of the process of transport at sea may have to be reviewed. It is suggested that the trend should be towards presenting error, rate of change and forecast data.

This paper aimed to elaborates and compares the performance of Fuzzy Time Series (FTS) model with Markov Chain (MC) model in forecasting the Gross Regional Domestic Product (GDRP) of Bali Province.  Both methods were considered as forecasting methods in soft modeling domain.  The data used was quarterly data of Bali’s GDRP for year 1992 through 2013 from Indonesian Bureau of Statistic at Denpasar Office.  Inspite of using the original data, rate of change from two consecutive quarters was used to model. From the in-sample forecasting conducted, we got the Average Forecas­ting Error Rate (AFER) for FTS dan MC models as much as 0,78 percent and 2,74 percent, respec­tively.  Based-on these findings, FTS outperformed MC in in-sample forecasting for GDRP of Bali’s data.

GSP module of new intelligent electric automobile chassis navigation system. GPS positioning system mainly uses the technology is very mature GPS module with single- chip microcomputer interface communication completed, use more convenient, more accurate positioning. The design of the electric navigation system with global positioning, automatic control, good real-time performance and so on various advantages for an organic whole, used in today's car has a good development prospect.

The problems of integrating aircraft using area navigation into the terminal A.T.C. environment are discussed. It is concluded that area navigation systems currently available are incompatible with current terminal A.T.C. approach sequencing and that integration is only possible in the context of both computer assistance to the approach controller and data link between the A.T.C. computer and the aircraft navigation system. The benefits of Terminal Area Navigation are briefly considered and it is suggested that the deployment of vertical navigation in a procedural role might be the better first step. The paper was presented at the 19th Technical Conference of I.A.T.A., Dublin, 1972. Crown copyright.Currently available area navigation (R NAV) systems range from simple station-oriented single waypoint systems, allowing flight on paths which do not coincide with VOR radials, to complex systems in principle enabling flight from origin to destination along a pre-programmed route, including flight on a standard terminal arrival route (from holding point or feeder-fix to the approach gate). As far as Terminal Area Navigation is concerned it appears that the main objective to the R Nav system designers has been to provide a system which enables automatic navigation along the standard terminal arrival routes, as depicted in the Jeppeson Charts, and to display to the pilot his progress along the route. It appears that designers of the more sophisticated systems have tacitly assumed that when an R Nav aircraft enters the terminal area A.T.C. will be able and willing to allocate it such a route.
