| 121 | High-capacity location and identification system for cooperating mobiles with frequency agile and time division transponder device on board | US11665256 | 2005-10-11 | US07570195B2 | 2009-08-04 | Simone Bartolini; Gaspare Galati |
| Cooperating mobiles (ground vehicles, aircraft) are located and identified by Multilateration and Automatic Dependent Surveillance-Broadcast (ADS-B) techniques using the frequency band and the format of the Secondary Surveillance Radar (SSR) signals in high traffic situations. Standard messages, transmitted by the mobile on the downlink channel, i.e. to a set of fixed receiving stations, and including the identification code, permit the location of the mobile by multiple time measurements (Multilateration) from a subset of the set of fixed receiving stations; when the message contains the position (GPS and, later, Galileo datum) the mobile may be located with the ADS-B when in view even of a few stations or of a single station. In order to overcome the problem that arises with high traffic, i.e. the superimposition of signals, called garbling. | ||||||

| 124 | Smart airport automation system | US11209473 | 2005-08-23 | US07385527B1 | 2008-06-10 | Odile H Clavier; David R Schleicher; Sharon W Houck; John A Sorensen; Paul C Davis; Cornelius G Hunter |
| A smart airport automation system gathers and reinterprets a wide variety of aircraft and airport related data and information around unattended or non-towered airports. Data is gathered from many different types of sources, and in otherwise incompatible data formats. The smart airport automation system then decodes, assembles, fuses, and broadcasts structured information, in real-time, to aircraft pilots. The fused information is also useful to remotely located air traffic controllers who monitor non-towered airport operations. The system includes a data fusion and distribution computer that imports aircraft position and velocity, weather, and airport specific data. The data inputs are used to compute safe takeoff and landing sequences, and other airport advisory information for participating aircraft. | ||||||
| 125 | Multilateration auto-calibration and position error correction | US209008 | 1998-12-11 | US6094169A | 2000-07-25 | Alexander E. Smith; Derrick D. Lee |
| The accuracy of multilateration systems can be greatly improved by using a correction method based on the SLS (Sideband Lobe Suppression) signal produced by a Secondary Surveillance Radar (SSR). Multilateration is a cooperative surveillance technique for aircraft equipped with Air Traffic Control Radar Beacon System (ATCRBS), Mode S, or Automatic Dependent Surveillance Broadcast (ADS-B) transponders. When one of these transponders aboard a vehicle is interrogated, it responds by broadcasting a message based on what the interrogation requests. These reply messages may be multilaterated to determine the source position of the transmission. Multilateration is a Time Difference of Arrival (TDOA) technique similar to triangulation. Multilateration can be performed to locate the transmission source of any SSR signal. Error detection and correction may be performed on the system by conducting a comparison of a known TDOA for the receiver/transmitter geometry, to the measured TDOA from a Side Lobe Suppression (SLS) pulse emanating from a primary radar. | ||||||

| An automatic dependent surveillance (ADS) system for tracking aircraft includes a GPS navigation receiver for determining the position of an aircraft, a Mode S transponder for transmitting the position of the aircraft, and a Mode S receiving station for receiving the aircraft's position and for determining the position of the transmitting aircraft relative to other aircraft and the ground. The Mode S position information is broadcast as a squitter on a random time basis having a present average transmission rate, or in response to an interrogation signal from a Mode S receiving station. The Mode S receiver can be another aircraft, an en route ground station, and/or a terminal ground station. The en route ground station can include a multi-sector receiving antenna with each sector connected to a separate Mode S receiver. The terminal ground station can include an omni-directional antenna connected to a Mode S receiver. The Mode S transponder transmits a formatted message having airborne or surface position information including the type of GPS signal used to determine the aircraft's position, the latitude and longitude of the aircraft, the barometric altitude of the aircraft, the magnetic heading of the aircraft, and movement characteristics of the aircraft. The Mode S data link can convey differential GPS correction information to the aircraft. | ||||||
