Abstract
ABSTRACT
This invention depicting the POSITION DETERMINING NAVIGA-TIONAL SYSTEM is relating to the radio detection systems and location awareness systems. It being wholly dependant on the radial discrimination of a pattern, radiating from the PDNS
antenna system. By the use of this radial discrimination, a simple radio can be modified to display the recognition of such pattern and thus it can associate the heading of the location. The same concept when fully developed offers auto-matic navigation, automatic anti-collision maneuvers, and general traffic awareness. As the by-product of this invention and the use of a computing device, a wind vector is produced for the purpose of calculating the economy of the flight.
This wind vector when transmitted together with altitude and location to a network system, and then to a central weather computer for the study and better forecasting.

Description
410,169 ~ 2 ~ 7 This invention relates to radio detection systems and orientation-navigation systems, more particularly it can combine the orientation-navigation and safety anti-collision warning systems into one light and compact system. It has numerous advantages over other systems, such as the fact that it can be applied while its going through it's stages of development, thus absorbing most of its development costs.
It 15 application pertains to land, sea, air7 and space location awareness. In its first stage it can provide a location by the use of a small pocket size radio receiver, which will display the radial compass headings of transmitting reference stations. Since the transmitter's antennae system can be wide apart, this will allow for the use of readily available electronic components of low cost, thus favouring mass production. In its next stage of development it can implement the use of (TTL,or MSI,or ECL) electronic compo-nents of fast switching capability, thus allowing for the transmitter's antennae system to become small enough to be installed on land, sea, air or space worthy crafts. This stage of development would give rise to proximity awareness of other crafts so equipped~ thus providing safety anti-collision feature. In its next stage of development it can incorporate a doppler shift sensitive device to give account of relative velocities of crafts in its vicinity, thus it can discriminate detween potentialy dangerous signals and those of no immediate concern to the safety of the craft. In its final stage of ~` ~10,169 ~ 7 development lt can be coupled wlth a micro-computing device which in turn can guide the craft~s auto-pilot to desired destination or alternate one at moments notice, as well as it could perform a logical maneuver in order to escape an apparent collision with other craft~ Furthermore the micro-computing device will discriminate the frequencies with greater accuracy, thus allowing for TV-like display of traffic and navigation stations in its vicinity. Also at this stage intelligence communication can be established on these frequencies thus further the potential of this invention.
Briefly, the subject invention contemplates the use of a transmitter system and a receiver system. The transmitter transmits a pulse in three frequencies in predetermined intervals of random duration through an antennae system that is composed of three basic rod type antennae of lengths complimentary to each frequency. Frequencies must be such as not to interfere with each other's omnidirectional radiation patterns. This will cause an overall pattern that will be unique at each point of radial circumference of the transmit-t~r. It should be noted that the antennae do not have to be equadistant for unique pattern, but that equidistance is desired for optimum in simplicity. The receiver si~ply does a comparison on the arrivalS duration or exi-t times of each frequency and thus determines the radial of the pattern.
Since all the transmitters will direct common pattern into 410,169 ~ 7 the northerly direction, it will allow for radial compass heading discrimination, thus to determine the direction from which the signal is coming from, a simple reverse logic can be applied (through the rotation of the display by 1~0 deg-rees).
It should be stated that this inven-tion can operate on more than three antennae7 giving the same features, using more radio frequencies, and potentialy be able to transmit more intelligence.
It should also be stated that this invention can function at a greater complexity on only two antennae and two frequen-cies. In this form of the invention it would be necessary to incorporate a computing device and the transmission of heading on one of the frequencies, and posibly altitude in the case of an aircraft. By the assessment of the time delays of the frequencies, the headings of each craft, and the doppler shift, and the strength fluctuation of the sig-nals a relative position can be established of a craft in the proximity.
I is yet another object of this invention to provide a beam of private data transmission on any one radial at a time, leaving the rest of the radials with scrambled data trans-missions.
It should be stated that the transmitter~s antennae sys-tem is novel only in the function it provides and the seeking of northerly direction,thus it can be of various designs.
~1 ~10,169 ~ '7 It is yet another function of this invention to supply inforrnation to the computer necessary for the determination of the true course of the aircraft, and thus the determina-tion of encountering wind vector. Wind vector being the by-product of this fully developed invention can be at the time when it's indicated value changes transmitted to a ground network. This transmission can be consisting of the following information; location in terms of navigating sta-tions, altitude,winds direction and velocity. Furthermore these weather transmitters can perform this function on time sharing basis. The information from the network can than be fed into a central computer for better weather forcasting.
It should also be stated that the principles of this invention can be applied to number of disciplines. One such discipline is the structure of three-way speeker systems.
By placing tweeter, midrange, and woofer speakers into a triangular lateral configuration, the radial sound will gain a pattern that will decentralize the focus of the sound, thus provide more realism to the reproduction.
It should also be stated that this invention deals with the heading problem of northern and southern hemispheres in an ingenious way, Since it uses the true headings of the stations to derive its own true course. It introduces the concept of longitudinal lines running from each navigational reference station, thus doing away with magnetic variations and overall complexity in navigation.
