Abstract:
A system for monitoring an aircraft interior may include a multiplicity of sensors each placed at a selected location of a plurality of locations within the aircraft interior. Each sensor is configured to monitor a condition in an associated area of the aircraft interior. The system may also include a server onboard the aircraft. The onboard server is configured to receive data from each of the multiplicity of sensors and to control operation of each of the multiplicity of sensors. The system may also include a router onboard the aircraft. The onboard router is configured to communicate with a router off-board the aircraft and to transfer data from the onboard server to the off-board router. The off-board router is associated with a ground monitoring facility that is configured to analyze data from each of the multiplicity of sensors, check or compare the data to reference data and depending upon any levels being exceeded an appropriate alert may be generated.
Abstract:
A method and apparatus for maintaining a vehicle. Identification information for a part on the vehicle is read from an automated identification technology tag, wherein the automated identification technology tag is on the vehicle and associated with the part. Part information for the part is retrieved from an onboard data processing system on the vehicle using the identification information for the part. The part information retrieved from the onboard data processing system may be displayed to a user. The part information stored onboard the vehicle may be synchronized with an off-board system.
Abstract:
Provided are methods and systems for terrestrial data transmission between aircraft and external networks, such as airline networks and/or airport networks. While an aircraft is landed, various data domains may need to be transmitted between the aircraft and such networks using two or more communication channels available to the aircraft. These channels may include wired and/or wireless channels, such as broadband over power line channels, Ethernet channels, Wi-Fi channels, and cellular channels. The available communication channels are allocated to transmit particular data domains based on the security levels of these channels. For example, aircraft control domains may be transmitted using a more secure communication channel than passenger information domains and/or entertainment systems domains. In some embodiments, multiple communication channels may be used to transmit the same domain parsed into multiple transmission packets. The packets are recombined back into the data domain after the transmission.
Abstract:
Provided are methods and systems for terrestrial data transmission between aircrafts and external networks, such as airline and/or airport computer systems. When an aircraft is parked at the gate, the aircraft is connected to and powered by an electrical cable, such as a stinger cable. This cable may be also be used for wired data transmission between the aircraft and the gate using broadband over power line (BPL) technology. The gate and the aircraft are each equipped with a BPL module. The aircraft may include other communication modules, such as a Wi-Fi module, a cellular module, and/or an Ethernet module. These other modules can be also used for data transmission in addition to or instead of communication through the BPL module. A communication link manager may be used to select one or more communication modules depending on availability of communication links, costs, speed, and other parameters.
Abstract:
Methods and systems for communicating data between an aircraft and an off-board network are provided. The method includes pre-loading data for the aircraft onto a secure power unit, communicatively coupling the aircraft to the secure power unit, validating the aircraft at the secure power unit based on air traffic management information, absolute (GMT) time, and aircraft location data, and transferring data between the aircraft and the secure power unit based on the validation.
Abstract:
Managing aircraft satellite communication data traffic is provided. The method comprises calculating total available satellite communication bandwidth across a number of virtual local area networks (VLANs) of an onboard network of an aircraft and prioritizing data traffic for the VLANs according to a specified traffic priority and quality of service policies. The prioritized data is mapped to a number of unified device routing tables to maximize the available total satellite communication bandwidth and meet the quality of service policies. When data packets are received from the VLANs they are allocated across the total available satellite communication bandwidth based on the mapping. The data packets are then transmitted over a single continuously connected VLAN mapped to a satellite communication link from the aircraft to an end station.
Abstract:
Provided is a method for determining access permission for a beamforming computing device communicating with a beamforming transceiver. The method includes obtaining, at an inter-zone sensor, location information from the beamforming computing device, wherein the inter-zone sensor is configured to monitor a location of the beamforming computing device; determining, by the inter-zone sensor, the location for the beamforming computing device based on the location information as the beamforming computing device nears a boundary between a first access zone and a second access zone; providing, by the inter-zone sensor, the location to a central control system; obtaining, by the inter-zone sensor, a command by the central control system that instructs the inter-zone sensor to communicate access instructions to a beamforming transceiver in the second access zone; and providing the access instructions to the beamforming transceiver.
