Description
Technical field
The present invention relates to a kind of security of operation data handling system and method, the security of operation data handling system and the method in especially a kind of RVSM (Reduced Vertical Separation Minimum is called for short RVSM) spatial domain.
Background technology
Development and national economy sharply rises to the demand of air traffic transportation.In order to increase airspace capacity, improve the on-road efficiency of airline, alleviate the operating load of air traffic control system, just International Civil Aviation Organization's (International Civil Aviation Organization is called for short ICAO) began one's study from the seventies RVSM typical problem and RVSM airspace operation safety assessment and surveillance technology.RVSM is meant at 29000 feet of height layers (8850 meters) to the spatial dimension between 41000 feet (12500 meters), minimum vertical between the aircraft is reduced into 1000 feet (300 meters) by 2000 feet (600 meters) in past at interval, thereby make the quantity of flight level in this spatial dimension be increased to 13 from original 7, available flight level quantity has increased by 86%, significantly improves airspace capacity.
The reduction of flight level perpendicular separation has obviously increased the probability of normal impact between the aircraft, influences aviation safety.Regulation according to ICAO, tracing and monitoring and assessing after safety assessment before the country of each implementing plan RVSM must be implemented its relevant spatial domain and the enforcement, to guarantee that the spatial domain safety index satisfies Security Target level (the Targetlevel of safety that global system performance specification and ICAO define, abbreviation TLS) requirement, thus the lasting safe operation of RVSM is built up confidence.A lot of in the world at present countries have all implemented RVSM, and have realized RVSM spatial domain safety assessment and security monitoring.
Aspect the safety assessment of RVSM spatial domain, various countries mainly utilize traditional Reich normal impact risk model to assess.The normal impact risk mainly is made of technical risk and operation risk two parts.Technical risk is to keep the inexactness of equipment to cause by the aircraft height, specifically comprises airborne height-finding system sum of errors Flight technical error.Operation risk is to be caused by the big height tolerance that exists in the RVSM airspace operation, and big height tolerance mainly is to be caused by operability error, emergency condition, strong meteorological condition and the factors such as decision information of airborne collision avoidance system.Reich normal impact risk model has been considered the technical risk relevant with normal impact, in conjunction with airspace structure factor and airflight stream feature, the quantification that has constituted spatial domain normal impact risk by parameters such as vertically superposed probability, lateral overlap probability and cross-over frequencies describes, and provided the risk assessment computing method under six kinds of different vertical collision status.But the Reich model is not considered operation risk comprehensively, ignored may produce the aircraft normal impact artificial, meteorological, control is regular and the factors such as special circumstances of implementing country, has the comprehensive and accurate inadequately defective of assessment result when causing utilizing the Reich model that the assessment of normal impact risk quantification is carried out in the RVSM spatial domain of certain areas.
Aspect the security monitoring of RVSM spatial domain, the whole world main employing ground and airborne two class height surveillances keep performance to monitor to the height of aircraft at present.Ground height surveillance mainly contains aircraft absolute altitude measuring unit (the Aircraft Geometric HeightMeasurement Element of U.S.'s research and development, be called for short AGHME) and two kinds of the height monitor units (HeightMonitoring Unit, abbreviation HMU) of Europe research and development.The shortcoming of ground height surveillance is that system coverage area fixes, and the aircraft monitoring range is limited, and system cost is high.Airborne height surveillance is based on GPS (Global Positioning System, abbreviation GPS) (the GPS Monitoring System of technology, be called for short GMS) system: it is at first gathered gps signal and obtains carrier phase information, the carrier phase benchmark that utilizes international GPS service network to provide then carries out difference and resolves, and draws high-precision aircraft elevation information.International geodynamics service network (InternationalGPS Service for Geodynamics is called for short the IGS net) is by the unified management of international GPS service organization, and it can in time provide data such as gps data and high-precision ephemeris for global scientific research institution.The IGS research station spreads all over the world, more in the website quantity that the U.S. is domestic, distributed areas are extensive, and the U.S. has a plurality of IGS data centers within the border and unified management organization carries out the IGS data sharing, for GMU equipment provides accurate difference benchmark based on the location compute of carrier phase.And some country website distribution is sparse, the condition that does not possess the uniform data management and use, and this just highly keeps the performance error monitoring to use the problem of having brought to cover four corner GMU within the border in these countries.
