This paper presents the results from a test of performance several general trajectory prediction methods and proposes hybrid model that aims to increase safety flights en route improve airspace management capabilities by predicting aircraft’s four-dimensional (4DT) more accurately. The automatic dependent surveillance-broadcast (ADS-B) data 589 trajectories cruising aircraft Guangzhou area were...

In this paper we investigate (in)security aspects of Automatic Dependent Surveillance-Broadcast (ADS-B) protocol. ADS-B is intended to be widely deployed in Air Traffic Management (ATM) Surveillance systems by 2020. One of the goals of ADS-B is to increase safety of air traffic. While the security of ADS-B was previously questioned, in this paper we demonstrate that attacks are both easy and pr...

Currently, the technology used for aircraft monitoring is Radar technology. Radar's accuracy hampered, however, by fact that while an airborne or in flight, it frequently obscured clouds, making difficult to detect aircraft. Due constraints radar technology, Automatic Dependent Surveillance-Broadcast was developed improve performance of air navigation security. Raspberry Pi, RTL-SDR, and LNA we...

With the exponential increase in volume of automatic dependent surveillance-broadcast (ADS-B), and other types air traffic control (ATC) data containing spatiotemporal attributes, it remains uncertain how to respond immediate ATC access within a target area. Accordingly, an original multi-level disaggregated framework for airspace, its corresponding information management is proposed. Further, ...

As technology and innovations in unmanned aerial vehicles progress, so does the need for regulations place to create safe controlled flying scenarios. The Federal Aviation Administration (FAA) is a governing body under United States Department of Transportation that responsible wide range regulatory activities related airspace. In recently published final rule, FAA addresses several concerns su...

The U.S. air traffic control system is reliant on legacy systems that artificially limit air traffic capacity. With the demand for air transportation increasing each year, the U.S. Federal Aviation Administration has introduced the Next Generation (NextGen) upgrade to modernize the air traffic control system. Automatic Dependent Surveillance-Broadcast (ADS-B), a key component of the NextGen upg...

With the change of time arise the need to work on image processing. This paper gives work on two aspects of image. One Recovery or reconstruction of image and at the other end it is for object detection.This paper investigates the possibility of reconstruction of images. This paper is concerned with a removing corruption of an image and remove problem in image. We propose a new algorithm for so...

The Automatic Dependent Surveillance Broadcast (ADS-B) system is a key component of CNS/ATM recommended by the International Civil Aviation Organization (ICAO) as the next generation air traffic control system. ADS-B broadcasts identification, positional data, and operation information of an aircraft to other aircraft, ground vehicles and ground stations in the nearby region. This paper explore...

Ten Azotobacter cultures were isolated from the maize rhizosphere and their auxin producing ability was measured colourimetrically. The auxin production by three efficient Azotobacter cultures (Z1, Z3, Z4) was also measured in the presence of filter sterilized L-tryptophan (at 10G, 10G and 10G M). Azotobacter culture Z4 gave relatively higher auxin production and was selected for further experi...

sified due to national concern about wildlife associated with them. Sage-grouse and other native fauna closely associated with sagebrush plant communities are thought to be declining in many areas. Several range-wide petitions have been filed for listing the sage-grouse under the Endangered Species Act. The black-tailed prairie dog, often associated with sagebrush-grass types, and the sagebrush...
