In electronic positioning apparatus, especially for use with airplanes, including a radar for periodically measuring the distance of the apparatus from each of two spaced apart reference stations and for continuously computing the position of the apparatus relative to the two reference stations with the use of a known baseline between the two stations, a method of determining the length of the baseline and introducing the information to the apparatus including positioning the apparatus over one of the two reference stations and utilizing the apparatus to measure the distance, storing the measured distance in a memory readable by the computing portion of the apparatus and electrically connecting the memory to the apparatus for use in computing the position of the apparatus.

In conjuction with electronic positioning apparatus, including means for substantially continuously measuring the distance of the apparatus from each of two spaced apart reference stations each having a unique identification code and for substantially continuously computing the position of the apparatus relative to the two reference stations with the use of a known baseline between the two stations and further including a control unit having a keyboard and an “enter”switch combination, a multiple position switch and an associated memory for storing information used by the positioning apparatus for computing the position, the keyboard being operatively connected to different portions of the memory by different positions of the switch and the memory being operatively connected to the positioning apparatus in a final position for use of the stored information during computations, a method of setting up an operation comprising the steps of: (a) moving the multiple position switch to a first position, operating appropriate keys of the keyboard corresponding with a desired amount of offset between adjacent parallel paths and entering the information in the memory by operating the “enter”switch; (b) moving the multiple position switch to a second position, operating appropriate keys of the keyboard corresponding with the unique identification code of one of the reference stations and entering the information in the memory by operating the “enter”switch; (c) moving the multiple position switch to a third position, operating appropriate keys of the keyboard corresponding with the unique identification code of the other of the reference stations and entering the information in the memory by operating the “enter”switch; (d) moving the multiple position switch to a fourth position, operating appropriate keys of the keyboard corresponding with the length of the baseline between the two reference stations and entering the information in the memory by operating the “enter”switch; (e) moving the multiple position switch to a fifth position for connecting the position computing apparatus to the memory through the “enter”switch, positioning the apparatus over a first point on a first path and operating the “enter”switch to enter the position information in the memory, and moving the apparatus along the first path to a second point on the first path spaced from the first point and operating the “enter”switch to enter the position information in the memory; and (f) moving the multiple position switch to the final position.
