Problems solved by technology
[0003] Among the existing equipment, the cockpit display traffic information (CDTI) and automatic dependent surveillance-broadcast (ADS-B) systems can provide traffic situation information within a certain range of airspace centered on the own aircraft and position information of each aircraft in the formation, but Pilots can only know the approximate position of the flight formation, without clear definition and quantification of their own safety assessment, and the accuracy cannot meet the requirements of tight formation
At present, pilots can only rely on visual inspection to roughly understand the position of the aircraft in good weather, and maintain formation by aiming at preset markers. This method requires pilots to invest a lot of training and maintain a high degree of concentration, resulting in a high workload. ; At the same time, pilots cannot obtain the precise position status information of each aircraft in the formation, and it is difficult to predict, quantify and make decisions on potential collision threats and position deviations, which increases the safety risk in flight; Application limitations in environments such as , clouds, and adverse weather conditions

The invention relates to the fields of relative navigation and formation flight indication, in particular to a portable formation flight indicator based on inertial / satellite relative navigation. The problem to be solved by the present invention is to develop a formation flight indicating device. By assembling the device for all aircraft in the formation, the formation of the flight formation and the construction of the communication link are realized, the initialization of the formation information and the flexible change of the formation formation are realized. Provide accurate and visual display of relative position and speed information among all aircraft in the formation under all-weather conditions, realize automatic judgment and alarm of position deviation / collision threat, and assist pilots to complete tight formation maintenance.
Description
technical field [0001] The invention belongs to the technical field of navigation and formation flight indication, and relates to an airborne formation flight indication system based on inertia / satellite relative navigation. Background technique [0002] For different purposes such as civil and military purposes, when it is necessary to realize special-purpose formation flight (such as military parade formation, flight aerobatic performance or military aircraft formation mission), it is often required to keep a very close distance between aircraft. This tight formation mode increases the Interference between aircraft and even the risk of mid-air collision directly affect flight safety. Therefore, it is necessary to provide pilots with accurate and reliable navigation information in the formation, provide relative position and speed information among members, and early warning of position deviation and collision threat in a visual way, assist pilots to complete formation main...
