(For larger maps respectively longer and/or wider strips will be necessary.)
  • the strip width is 9 inches. If we place this "width" longitudinally then we need to define the preferred embodiment's width. If we look at a visible map width of say 9 inches, as the map can be displayed almost to the edge of the case, then we can expect the total outer case dimensions to be approximately 9.25 inches by 9.25 inches by 1.5 inches thick.
  • This outer case is the cassette holding the reel of film with the map printed upon it. We therefore have a space between the rollers and below the map to hold the electronics, batteries and drive motors of approximately 9 inches by 6.25 inches by 1.25 inches. This relates well to the first prototype hand held GPS unit proposed by Inmos (and currently being tested) - 7 inches by 5 inches by 1 inch thick.

Abstract

La présente invention se rapporte à un système de navigation de préférence portatif, qui utilise des cartes imprimées combinées avec un système de repérage de position. En utilisant un système de navigation portatif capable de recevoir des informations de position depuis des satellites et similaires et de transformer les informations ainsi reçues en informations visualisées sous une forme soit compréhensible par une machine soit compréhensible par l'utilisateur, et en produisant une carte sous forme de feuille sur laquelle la position de l'utilisateur peut être affichée en fonction des informations de position reçues, on obtient un système de navigation portatif sous une forme plus facile à utiliser et plus précise que les systèmes de navigation entièrement électroniques existants. Dans son mode de réalisation préféré, le système de navigation portatif de la présente invention se compose d'une cassette (1) pouvant contenir une carte et interverrouillable avec un récepteur (2) compatible avec le système de repérage de position mondial, le récepteur assurant l'entraînement à la fois de la carte dans sa cassette (1) par rapport à une ligne fixe (4) et d'une aiguille mobile (5) afin d'indiquer la position de l'utilisateur à l'intersection de l'aiguille (5) et de la ligne (4) sur la carte, laquelle est visible à travers le boîtier transparent (3) de la cassette (1).
