DE19848947A1 - Orientation data input method for global positioning signal navigation device e.g. for aircraft navigation, uses location codes corresponding to geographical locations from programmable and transportable memory - Google Patents

Abstract

Method uses a programmable and transportable data memory (6), to which location codes corresponding to geographical positions on the earth's surface are transferred, for subsequent entry of the coded data into the global positioning signal navigation device (7) via the data memory. An Independent claim for an orientation data input device is also included.

Description

The invention relates to a method and a device for entering Orientie data in GPS navigation devices.

In densely flown airspaces, e.g. B. the Federal Republic of Germany, especially here close to the airport, precise navigation of the aircraft is essential.

The so-called satellite-based now has a high-precision location GPS navigation procedures continued the state of the art.

Because of the high geographical resolution possible with this technology, corresponding coordinate data correspondingly extensive. On average, these are 10 to 24-digit columns.

Currently, this data, which is dependent on the respective flight order, becomes the relevant one Navigation devices entered manually.

Because of the extreme number lengths and their not directly recognizable reference to one Orientation point, there is an excessive risk of incorrect input of coordinates.

The object of the invention is to provide a method and a device that human error when transferring and entering navigation data into a GPS Exclude navigation device.

The solution succeeds according to the method specified in claim 1 and a one Direction according to claim 5.

With the invention it will be possible in the future that the transfer of the extensive Na navigation data reliably without special retention and thinking effort by the operator can be handled.

Advantageous refinements of the invention can be found in subclaims 2 to 7 to take.

The claim 2 relates to a way of generating the in process ren used codes to carry out by a corresponding application software to let. Any location of a representation of the software displayed on a screen by the software For this purpose, the surface of the earth can be marked with a computer mouse pointer the. According to the program, a code is output after this information, the procedural continues to be used.

In addition to software handling of the method according to the invention, Claim 3 specified a variant based on the conventional symbolic representation the surface of the earth, in the form of a map. The representation of the for that The method used is additionally printed in printed form either in the card picture yourself or on a separate map part. The first should be preferred  named version, in which the code is directly assigned to a geographical reference point should be net.

In principle, any code that can be graphically represented is for the inventive code Procedure usable. The claim 4 also gives an indication of the appro priate netst respected bar code, which is also known to general circles as "barcode".

Because read errors can happen when transferring the code, the claim 6 proposed a plausibility and data verification function, either in portable memory or in the computing unit in correspondence with the memory can be realized.

In the case of a software-based method execution, according to claim 7 beat, the generated code in a scalable screen area, which ver display should be slidable.

In addition to the display on a screen, it is possible according to claim 8 before suggested barcode also on an external display device to represent half of the computing unit.

An embodiment is described below. A sketch serves for further Clarification.

A data processing computing unit 1 (DV computing unit) is shown in the sketch. This unit can be represented with a conventional personal computer. An application memory 2 is assigned to it. Internally or externally, the application program required for routine procedure execution is stored here.

The software is suitable for displaying part of the earth's surface graphically on a display (screen). A specific location on the map can be marked with a pointer, which is guided over the displayed map by the director 4 . The aforementioned application program generates a code for this selected location.

The code should preferably be displayed in the form of a bar code. A special area of the map display on the display 3 is usually suitable for this. The area should be movable and scalable in the display area.

The function of code generation can be integrated as a software module in the application program itself or can be performed by a separate coding module 5 .

Of course, it is possible to have several geographic locations one after the other the desired route, to have it encoded and its codes listed in caching a buffer for preparation for output.

If required, the codes are output in display 3 . With a programmable and transportable memory 6 , which has a reading interface for reading the displayed code, the code is read and stored in the memory 6 .

If only the programmable and transportable data storage device 6 is used in the software-based version of the invention, a direct connection to the DV computing unit 1 is of course also possible.

After the code has been read in, the data read should be checked. This can be done in the memory 6 itself or advantageously with reference to the DV computing unit 1 , in which the originally generated code is still available for comparison.

After the completeness of the code transmission has been determined, it can be taken along with the data memory 6 to a GPS navigation device 7 to be programmed. Here, the data transfer interfaces from the data memory 6 and GPS navigation device 7 are brought into functional relation to one another and the data from the data memory 6 are copied into the corresponding navigation data memory of the GPS navigation device 7 . Like the previous data transfer, this data transfer should also be checked for complete correctness.
