Automatic dependent surveillance - contract (ADS-C) uses the same systems on board the aircraft to automatically transmit similar information - aircraft position, altitude, speed, elements of navigational intent and meteorological data - only to one or more specific Air Traffic Services Unit (ATSU) or AOC [1] facilities for surveillance and/or r...

configure to ensure best possible CPDLC / ADS −C performance – VHF/SATCOM media transitions – Media type priority selection for CPDLC / ADS −C (ATS) and AOC

2021年8月29日 · ADS-B and ADS-C are Air Traffic Control surveillance technologies used on modern aircraft that transmit highly accurate position reports (along with other information) from the aircraft. Although very similar in operation there some …

2023年8月16日 · By automatically transmitting essential aircraft parameters, ADS-C ensures accurate and real-time information for air traffic controllers, allowing for better decision-making and response in various scenarios. The implementation of ADS-C has revolutionized aviation, particularly in remote or oceanic areas with limited radar coverage.

2020年11月19日 · ADS-C基于点对点模式的航空电信网（ATN）数据链信道，ADS-C需要数据收发双方约定通信协议，如使用航空器通信寻址与报告系统（Aircraft Communication Addressing and Reporting System, ACARS）。

Each type of ADS C report (periodic, event,demand ) can contain different groups of information /data to be transmitted to the ground systems. ADS-C groups include: At a minimum, all ADS-C reports contain the basic group. Inability to determine position within 30 nautical miles is considered total loss of navigation.

ADS-C is a datalink-based way of requesting different types of information directly from the aircraft’s flight management system, without pilot interaction. This means it enables aircraft to automatically downlink aircraft intent to the MUAC system, which can …

SURVEILLANCE - ADS Contracts A contract = agreement between air and ground on information to transmit to the ground. Three types of contract defined : ADS basic group (interval T) + a set of additional groups with for each group a reporting rate defined as multiple of the basic reporting Demand Contract Event Contract Basic group + a set of

and remember traffic symbols that may be shown on Cockpit Displays of Traffic Information (CDTI). These displays convey data obtained from Automatic Dependent Surveillance-Broadcast (ADS-B) and related Aircraft Surveillance Applications System (ASAS) technologies, as well as other surveillance data sources.

2016年7月11日 · Traffic display standards for ADS-B traffic relay directional information by using an arrowhead symbol in either white or cyan. An altitude climbing or descending arrow, a directional vector line extending from the point of the arrowhead, and call sign are also shown for ADS-B Out traffic.
