Definitions

  • the present invention relates to a Navigation aid
  • PULSE-8 and OMEGA which provided the means for the location of a ship or aircraft on the Earth's surface to be determined to various degrees of precision and position update rates
  • a position fixing device contains two elements the position-determining sensor which determines location, and the processing and time measurement element which analyses information provided by the position-determining sensor and provides position and time-derived information such as speed, direction of travel, bearing, time and distance to destination, estimated time of arrival and off-track error
  • the process of zooming out will involve either displaying a map with a reduced amount of detail - and in practise this could mean that the road network the navigator wishes to study in order to plan a route may disappear - or, if the detaii of the map does not drop out a the user zooms out, the map will become cluttered with detail to the extent that it becomes unreadable.
  • the invention that is the subject of this application overcomes digital map-related problems by avoiding the use of digital map aids altogether, and presenting information to a user in such a way that without any equipment and with minimal skill a user may rapidly and easily identify a location on a conventional paper map.
  • all information that is expected of a conventional navigation receiver such as geographic co-ordinates, speed, bearing and distance to waypoint, off-track error and estimated time of arrival may be displayed
  • Maps are generally marked with a regular grid enabling points on their surface to be located with the assistance of an indexing system.
  • Grid lines run vertically and horizontally to form a matrix of squares or rectangles which may be referred to as cells Every cell has a unique map grid co-ordinate expressed by the letter or number across the top of the map identifying the cell's position to the left or right , and another letter or number identifying the cell's position between the top and bottom of the map
  • every cell has a unique identifier expressed commonly as letter, number plus a page number
  • the present invention provides an important link between the information provided by a GPS receiver and the use of a grid-marked map
  • a receiver of transmitted signals from a geographic position fixing system such as, for example, GPS, which receiver is operative to determine from the transmitted signals the current geographic co-ordinates of the Navigation aid
  • a navigation aid for use with printed maps comprising:
  • a receiver of transmitted signals from a geographic position fixing system such as, for example, GPS;, which receiver is operative to determine from the transmitted signals the current geographic co-ordinates of the navigation aid
  • an electronic database means storing data comprising definitive parameters of one or more maps or series of maps for definition of the correspondence between the coordinates of the map grid associated with the or each map and the coordinates of the geographic position fixing system;
  • the overlay is the front face of a waterproof wallet for the map.
  • the aid being adapted to display, at the users option, by operating a switch provided on the aid the geographic co-ordinates determined by the receiver or the corresponding map grid co-ordinates
  • Three segments of information - a graphic display of the cell, the identity of the cell and the point within the cell that corresponds to the user's location - are suitably displayed by the display giving the user the ability to refer to the map and identify on the map the cell that is displayed by the Navigation Aid and identify the point within that cell that corresponds to the user's precise location
  • the cell displayed by the Navigation Aid will preferably be the same size as the cell on the map but if the size of the cell on the map is too large to be displayed at 1 1 scale on the Navigation aid then the cell will be displayed at reduced size but with the same height to width ratio.
  • Navigation aid may be configured by the user so that the Navigation Aid system can be used in conjunction with any map that is geographically accurate.
  • the Navigation aid cannot be used with a map which is a diagrammatic or schematic map.
  • the identity of the other maps may also be displayed.
  • the relationship between the map cell structure and geographic co-ordinates must be established for each map.
  • the geographic extent of the area covered by each map cell must be entered into the Navigation aid's database indirectly or by a general formula from which the extent of each map may be determined.
  • a simple approach to achieve this would be to define the geographic co-ordinates of the corners of each cell on the map but this would require the Navigation Aid to store an unduly large amount of data.
  • a better approach is to identify the characteristics of the matrix of cells covering the map, identify the geographic co-ordinates of the corners of the map, and provide the Navigation aid with a conversion program enabling the geographic area covered by each cell to be determined. If the map to be used is a book of maps the area covered by each map must be determined or detemninable from the data entered into the aid's database.
  • Parameters are preferably stored as formulae in order to reduce the amount of data held within the aid's database.
  • a unique reference number is assigned to that data to enable it to be retrieved for use
  • the user may input the reference number of the map.
  • a sensor such as a bar code reader may be built into the Navigation aid enabling it to detect the identity of the map that is being used with the Navigation aid.
  • the conversion parameters necessary for converting wide area co-ordinates to map coordinates for a London A-Z can in principle be stored as 304 characters or bytes, provided that the data is held within a tightly defined structure, or format.
  • conversion data for a map can be held within 340 bytes meaning that 3 publications can be stored by 1020 bytes of information or 1 kilobyte (1 kilobyte has 1,024 bytes)
  • the location of the user can be displayed together with a line which indicates the past track of the user, and as the user moves across the Earth's surface so the Navigation aid will show the position-indicating point moving across the appropriate cell
  • the Navigation aid's display may be configured so that the user's position is always shown at the centre of the display, and as the user s position moves so the cell and adjoining cells will move so that the user s position remains at the centre of the aid If the user is moving North the displayed cell matrix will move down the aid, if the user is moving East the displayed cell matrix will move to the left of the aid
  • the display is suitably provided with the ability to zoom in or out so that as desired the cell can be seen as one of the whole range of cells on a complete page
  • the X representing the location of the user on the displayed cell image will still be shown in the correct position (subject to the resolution of the display screen), but the user will see his location moving across a page or part page of a map rather than simply moving across a specific cell of the map, giving the user a more intuitive feel for his progress
  • a user may be provided with the ability to superimpose a grid on the map in the form of a stable non-stretch template
  • the grid is defined by a regular pattern, preferably with parallel lines vertically and horizontally across the surface of the map at regular spacings, any arbitrary grid will suffice
  • the display is suitably adapted to enable points from a map to be entered
  • the Navigation aid software will suitably permit a user, having identified a point on a map, to input the point into the Navigation aid by entering the identity of the page that accommodates the cell and the identity of the cell that accommodates the point, and entering the position-indicating point within the cell
  • a user may see that his destination lies within cell G4 on Page 48 of map reference number 1234, and that the position on the map of the point to be entered into the Navigation aid is 3mm from the right hand margin of the cell and 8mm from the top of the cell
  • the Navigation aid operating software will permit the user to enter the information, e g that the destination lies within Cell G4 on Page 48 of map reference 1234, and that the relevant point lies 3mm from the right hand edge of the celi and 8mm from the bottom of the cell In instances where precision is not required the user will also be able to enter the approximate position point within
  • the user can enter geographic co-ordinates into the Navigation aid without being aware of latitude and longitude or any geographic co-ordinate system
  • a Navigation aid user can thus define a journey from start to destination as a series of waypoints and the user can enter the position of each waypoint into the Navigation aid
  • the Navigation aid sensing that it is approaching a waypoint will present the previously entered directions to the user Visibly displayed directions may be accompanied by an audible sound indicating to the user that a waypoint will shortly be reached
  • Directions can be displayed to the user in advance of the user reaching the point where directions are required, taking into account the user s speed In heavy traffic with the user's average speed being below 20 kph information may be displayed 200m before the point where directions are required On a motorway where the user may be travelling at 100 kph, directions may be displayed 1 km in advance
  • An additional feature of the Navigation aid may include a heading sensor so that the bearing of the destination relative to the user may be displayed graphically
  • the Navigation aid may be provided with the ability to receive information from other external databases For example, if the aid were adapted to access a database of campsites in Scotland, the user, while driving along a road, could ask the Personal Navigator what is the distance to the nearest camps ⁇ te(s) from my present location 9 The Personal Navigator could list campsites, starting with the nearest
  • the Navigation aid shows the user his location in terms of page number (if for an atlas), grid square and the location of the user within the map, on the grid square
  • page number if for an atlas
  • grid square the location of the user within the map, on the grid square
  • This is fine for a tourist using either product with a London A-Z, or a motorist using the product with a motoring atlas, but may not be as useful for a traditional user (a mariner navigating offshore) who wants to see his location presented in lat/long
  • a facility enabling a user to "toggle” or switch between "map interactive' operating mode (as referred to immediately above) and "conventional” operating mode displaying the conventional output of the GPS, or similar receiver where location is given in lat/long format
  • a further additional feature of the Navigation aid may include a destination-by-postcode facility enabling a user to define his destination by entering the postcode
  • the storage media for holding the database may be held within the Navigation aid or in an external device which may
  • the Navigation aid may include a bar code reader or other sensor as the map identity input means to enter the identity of the map with which the Navigation aid is being used.
  • the display may also be provided with a facility for receiving broadcast accuracy- enhancement signals, enabling the Navigation aid to present more accurate position information.
  • an display for use with a modified wallet where the front of the wallet (the clear plastic part of the wallet that protects the part of the map that the walker wishes to study) has a grid in it (eg, 1-20 across the top and A to T down the side))
  • the map is folded in the wallet so that it is impossible for the user to see any edge of the map, or in other words, he cannot see any part of the map co-ordinate system
  • the aid if the user were able to establish a relationship between the map co-ordinate system and the co-ordinate system on the front of the wallet, it would be possible for the aid to convert the geographic co-ordinate system (lat/long) or the map co-ordinate system to the co- ordinate system of the wallet.
  • a further additional feature may include the facility for a user to update the internal database to identify the relationship between a map and the geographic co-ordinates of the map, when this information has not been provided by the map publisher or any other provider of information.
  • the process will involve a Navigation aid user going to a point within the area covered by the map and manually identify the location of the point in terms of the cell structure (the identity of the cell and the location of the point within the cell) and identify the geographic co-ordinates of the same point This process may be repeated one or more times to enable the Navigation aid to establish the relationship between the geographic co-ordinates and the map's cell or pattern structure.
  • the display may be further provided with a facility whereby a user at sea may cover his chart with a clear overlay preferably of plastic which is marked with an arbitrary grid.
  • a clear overlay preferably of plastic which is marked with an arbitrary grid.
  • the squares of the grid would suitably be, for example, about 1 cm square.
  • the navigator could reference the grid to the chart by entering the lat/long co-ordinates of, for example, three plastic grid co-ordinates into the aid database.
  • a further additional feature may enable the Navigation aid to alternate the graphic display of cells with position and time derived information
