| 20090055038 | AUTONOMOUS AND AUTOMATIC LANDING SYSTEM FOR DRONES - The invention relates to an automatic aircraft landing guidance system having an electromagnetic detecting and locating device, positioned on the ground and a first multifunction transmitting/receiving radiofrequency beacon, on board each guided aircraft and transmitting in particular a continuous wave. The detecting and locating device uses the continuous wave transmitted by the beacon to perform a passive locating intended to improve the accuracy of the measurement of the angular position of the aircraft. It also comprises means for generating and periodically transmitting to the aircraft, via the beacon, information enabling said aircraft to rejoin an optimum landing path from its position. The invention applies more particularly to the guidance of autonomous and automatic aircraft such as drones in the approach and landing phase. | 02-26-2009 |
| 20090243911 | METHOD AND DEVICE FOR POSITIONING AIRCRAFT, SUCH AS FOR AUTOMATIC GUIDING DURING THE LANDING PHASE - The present invention relates to a method and a device for locating aircraft. A radar ( | 10-01-2009 |
| 20090284406 | METHOD USING RADAR TO DETECT A KNOWN TARGET LIKELY TO BE POSITIONED AT APPROXIMATELY A GIVEN HEIGHT, NEAR OTHER TARGETS POSITIONED AT APPROXIMATELY THE SAME HEIGHT - Using a radar to detect a known target likely to be positioned at approximately a predetermined height close to other targets, these other targets also being positioned at approximately the predetermined height. A first phase of detecting the known target is carried out by performing an azimuth scan. When the known target has been detected at a certain distance Di at a certain azimuth angle θaz, a second detection phase is carried out at said azimuth angle θaz and at an elevation angle θEL corresponding to that of an object situated at said distance Di at the predetermined height. The target is said to be detected if it is detected at the elevation angle θEL at a distance D approximately equal to the distance Di. | 11-19-2009 |
| 20090315755 | METHOD FOR DETERMINING THE POSITION, NOTABLY IN TERMS OF ELEVATION, OF A TARGET FLYING AT VERY LOW ALTITUDE - The present invention relates to a method for determining the position notably the elevation of a target flying at very low altitude. An electromagnetic detection system extracts the measurement of the elevation on the basis of the amplitude of the interference signal produced by a signal emitted directly by the target and by a signal emitted by the target towards the ground then reflected by the ground towards the radar. Embodiments of the invention can notably be used within the framework of the guidance of drones in the final landing phase. | 12-24-2009 |
| 20100085237 | DEVICE AND METHOD FOR LOCATING A MOBILE APPROACHING A SURFACE REFLECTING ELECTROMAGNETIC WAVES - Device and a method for locating a mobile object approaching a surface reflecting electromagnetic waves. The location device includes an emission antenna and a reception antenna. The emission antenna has one or more emission positions emitting a detection signal toward the mobile object. The reception antenna has at least one column of one or more reception positions, receiving a signal transmitted by the mobile object. An emission of the detection signal is activated on each emission position. An emission position that produces a detection by the reception antenna, of the signal of maximum energy transmitted by the mobile object, is selected to track the mobile object. One or more signals of maximum energy, received by one or more reception positions, are used to angularly locate the mobile object. The invention can be used to determine the position of an aircraft in the final landing phase for a guidance device. | 04-08-2010 |
| 20110118910 | Decision Aid Device for Assisting the Landing of an Aircraft on the Deck of a Ship - A device for aiding the deck-landing of an aircraft, the aircraft being controlled remotely from a mobile station, such as a ship, includes means for receiving data from the aircraft, notably attitudes of the aircraft, the aircraft hovering ready to land on deck, the deck-landing decision having to be taken under certain conditions that must all be met, the device including a computer making it possible to deliver temporal indicators indicating that all the conditions are met. The device includes a temporal gauge including a temporal graduation indicating mobile graphical zones representing the periods during which all the conditions are met for authorizing a deck-landing. | 05-19-2011 |
| 20110130898 | Method and System for Assisting in the Landing or the Decking of a Light Aircraft - The present invention relates to a method and a system for assisting in the landing or the decking of a light aircraft, the method being implemented by a system comprising a device on the ground for locating the aircraft, the aircraft having an onboard signal sender, the method comprising at least the following steps: the locating device on the ground uses signals sent by the sender to determine the position and/or movement of the aircraft; said device transmits the previously determined aircraft position and/or movement data to the aircraft; display means show at least some of said data made accessible to the pilot of the aircraft. The invention applies in particular to the field of civil light aeronautics, notably for facilitating the landing of pleasure aeroplanes, small transport aeroplanes and helicopters. | 06-02-2011 |
| 20110160941 | Broadband Multifunction Airborne Radar Device with a Wide Angular Coverage for Detection and Tracking, Notably for a Sense-and-Avoid Function - A multifunction airborne radar device includes a plurality of transmit antenna modules and/or receive antenna modules that are fixed relative to the aircraft, placed substantially over the surface of the aircraft so as to form transmit and receive beams, enabling targets to be detected for implementing a sense-and-avoid function. The airborne radar device may also comprise processing means for tracking the detected targets and for generating information sent to an air traffic control centre and/or to a control device on board the aircraft. The processing device may also receive data relating to the aircraft, enabling the antenna beams to be adjusted and the tracking calculations to be refined. | 06-30-2011 |
