Method, apparatus, and computer program products for alerting surface vessels to hazardous conditions A navigational system for surface vessels that provides warning of impending grounding occurrences. A data base of bottom contours and submerged obstructions is compared to various indicators of the surface vessel's position and motion to provide alerts and to display bottom hazards ahead of the vessel.

A battle damage monitoring device for monitoring, containing and eliminating leakage damages, fire damages and/or atomic, biological and chemical (ABC) contaminations after collisions, running aground, damages caused by weapons, etc. comprises an automation and monitoring system for installation, power, and unit failures, and a control station on which a perspective plan of a ship that depicts the compartments of the ship can be displayed. In order to enable a more rapid image generation of a situation after a collision, running aground or damage caused by weapons, a reporting element is placed in each compartment or in the area of a group consisting of several associated ship compartments. Said reporting element interacts with the battle damage monitoring device for boats in such a manner that, when activated, the depiction of the corresponding compartment or of the corresponding group of associated compartments in the perspective plan of the ship undergoes a change in color.

L'invention concerne un procédé d'enregistrement dans une base de données notamment d'un système de navigation et de positionnement de données géographiques de lieux géographiques choisis dans une zone géographique prédéterminée. Le procédé est caractérisé en ce que l'on choisit deux points sur une carte géographique de ladite zone, définit ces points par leurs coordonnées géographiques, telles que leur longitude et leur latitude, et par leurs coordonnées de position sur la carte, on établit la corrélation entre les coordonnées géographiques et de position, définit les points à enregistrer par leurs coordonnées de position, calcule pour ces coordonnées de position, d'après ladite corrélation, les coordonnées géographiques, et inscrit les coordonnées géographiques ainsi calculées dans ladite base de données. L'invention est utilisable par exemple par des randonneurs.
摘要:
A map display apparatus (10) operating with a map sheet (20, 40, 72, 80, 130) that is a base material on which a map is printed. The apparatus (10) includes a locating device (12) for detecting the user's present position to produce positional information, a map information display device (16) for displaying the map sheet and indicating positions, and a display controller (11) for marking the present location on the map information display device (16) based on the positional information provided by the locating device (12).
摘要:
A navigation system particularly adapted for ships making a passing within a harbor or the like, utilizing signal inputs from on-board vessel position determining equipment such as Loran or Decca apparatus and an on-board object detecting equipment such as a radar or sonar apparatus. The system further includes an on-board vessel position computer which operates in a differential Loran mode in response to observed Loran time differences, stored data from an initial calibration, and Loran grid offset data from an on-shore monitor system to compute a highly accurate current or present position fix in longitude and latitude whereupon the computer causes a predetermined electronic chart to be displayed in color on the screen of a cathode ray tube, being generated from a plurality of electronic charts stored in the form of digital files in memory. The selected chart, together with the present position of the ship, is displayed along with preselected alpha-numeric indicia of data relating to bearings, way points, ranges, "time to go", etc., also generated in accordance with the computed vessel position. Radar target returns of the local land mass and other stationary moving targets are additionally received by the ship's radar. The radar image of the target echoes is next referenced to and superimposed on the electronic chart generated; however, the radar's land mass echoes are suppressed in favor of the electronic chart land mass while displaying all other targets.

摘要:
Système permettant de localiser un objectif, ou le drone, ou d'effectuer d'autres mesures, sans utiliser de dispositif détecteur de position au niveau de la station. Il comporte des moyens d'émission-réception (5, 6) pour la télécommande de vol et d'orientation de la caméra (3) à partir du sol. Des capteurs (4) indiquent l'attitude du drone en roulis, en cap et en assiette ainsi que sa mesure d'altitude ou la distance par rapport au sol le long de la ligne de visée (LV). La station au sol comporte un calculateur, un moniteur de visualisation (8) de l'image détectée et en outre, un indicateur cartograpique (10). A l'aide d'un crayon optique (11) on désigne sur l'image et la carte un amer (A) commun et sur l'image l'objectif (B). Le calculateur effectue en conséquence, à partir de ces désignations etdes paramètres d'attitude précités, le calcul de la localisation géographique de l'objectif.
摘要:
Ein Navigationsrechner (12) liefert die Position eines Fahrzeuges in Gitterkoordinaten. Diese Position wird durch einen in zwei Koordinaten steuerbaren Lichtsender (122) auf einem Kartenblatt angezeigt, das in einer Kartenaufnahme (40) des Positionsanzeigegerätes (36) gehaltert ist. Kartendaten der verfügbaren Kartenblätter sind in einem Speicher gespeichert. Ein Mikrokomputer steuert den Lichtsender (122). Wenn der Lichtsender (122) den Rand des Kartenblatts erreicht wird ein Randsignal erzeugt. Der Mikrokomputer prüft dann anhand der gespeicherten Kartendaten, ob die vom Navigationsrechner (12) gelieferten Gitterkoordinaten auf einem der vorhandenen Kartenblätter anzeigbar sind. Ist dies der Fall, wird die Kennzeichnung des Kartenblatts auf einem Anzeigefeld (44) angezeigt und der Lichtsender (127) in die Stellung verfahren, die in dem neuen Kartenblatt den Gitterkoordinaten der Fahrzeugposition entspricht. Anderenfalls erfolgt eine Fehlanzeige.
