Advanced Receiver Autonomous Integrity Monitoring (ARAIM) is a new Aircraft Based Augmentation System (ABAS) technique, firstly presented in the two reports of the GNSS Evolutionary Architecture Study (GEAS). The ARAIM technique offers the opportunity to enable GNSS receivers to serve as a primary means of navigation, worldwide, for precision approach down to LPV-200 operation, while at the same time...
In this paper, we present PaTSI, a tool for analyzing evolutions of objects in time series of satellite images. This tool is a plugin integrated in the KNIME Analytics Platform. PaTSI is a workflow composed of several nodes assembled together to form a whole KDD process (data selection, pre-processing, image segmentation, pattern mining and visualization). Input data consists of a time series of satellite...
The specification of non-functional requirements, e. g., on timing forms an essential part of modern system design. Modeling languages such as MARTE/CCSL provide dedicated description means enabling engineers to formally define the ticking of the clocks to be implemented in terms of clock constraints and the actually intended timing behavior in terms of instant relations. But thus far, instant relations...
In this paper, we develop an efficient design for a decision engine (DE) with anti-jamming (AJ) capability for advanced wideband satellite communication (SATCOM) systems. Our goal is to design a decision engine that evaluates the statistical observations of spectrum and link metrics provided by the co-located dynamic spectrum access (DSA) components. Upon the evaluation of the observations provided...
For the monitoring of high-voltage-overhead-lines, automated robotic systems increasingly come to use. Regardless of whether this is set to linecrawler-technology or aerial platforms, Global Navigation Satellite Systems (GNSS) are used for navigation and geo-referencing on nearly all of these robotic systems. In order to test the function and quality of GNSS-receivers and -antennas at these environmental...
In the satellite integration and verification process, test engineers tend to use a set of traditional methods like synoptics and direct telemetry inspection to assess significant measurements of the Equipment Under Test. The definition and implementation of this synoptics are not straightforward and imply a considerable effort as well as knowledge of the complete environment. Here we present an advanced...
The paper describes the project “Integrated technologies for fire monitoring and first alert” proposed by the authors to satisfy technical requirements of the Firefighter Bodies with particular attention to the monitoring of wood fires and release of chemical materials. The target system is composed of three sub-systems: sensors to detect target parameters, telecommunications to transfer sensor data...
An artificial Satellite's health and functioning in space is monitored by analysing the stream of Telemetry Data received at the Satellite Ground Control Centre. This data is received continually during the entire mission life of the Satellite. Hence a huge volume of Data is collected for any given satellite. Data Mining techniques are now regularly applied to analyse such large quantity of data for...
Utilization of Unmanned Aerial Vehicle (UAV) for observing landscape is rapidly increasing because it is fast a fast way which provides data on demand with an appropriate resolution. Data are suitable for next processing and analyses and the whole procedure is reasonably cheap. It is necessary to propose and describe a suitable process for data collection and processing to repeatedly obtain correct...
We live in an ever-changing environment where there is a vital need for persistent monitoring of human activities; whether it is for security, safety, economic or environmental purposes. Our oceans are no exception and may even be the region of our globe that is most at risk. Unbeknownst to many, there is limited visibility and awareness of maritime activity beyond 40-50 nautical miles from our coastline...
In recent years, many studies have been conducted on coastal erosion. In addition, the monitoring of bathymetry changes in shallow water regions is being acknowledged as an important aspect of studies on coastal erosion. Erosion monitoring implies monitoring of the bathymetry changes after the occurrence of major causes of erosion, such as typhoons. However, it could be very difficult to use the sensors...
Satellite telemetry of meteorological satellite plays an important role for satellite safety management. In existing system, threshold value is used to monitor the abnormity because of large volumes of data which is collected every three seconds. However, the abnormal data in the threshold range cannot be detected timely. Based on this, in the paper we introduce Principle Component Analysis (PCA)...
In this paper, a novel framework, called Object -- Coriented random forest classification (OORFC), is proposed for Entheromorpha prolifera (E. prolifera) detection based on RADARSAT-2 Synthetic Aperture Radar (SAR) imagery obtained from 2011 to 2013 in the coastal areas in the Yellow Sea. Firstly, each SAR image is processed by multi-scale segmentation to generate patches with homogeneous attributes...
Wetland is a very important part in ecological system and it offers various animals and plants habitat. Red beach which grows in tidal zone and intertidal zone between sea and land is one of wetlands with high productivity and variety. Wetland is a natural resource in fast dynamic property and one of currently important wetland remote sensing studies to extract and analyze wetland information. This...
As the most abundant inland river of water resource in Liaoning province, Hun River affords industrial and agricultural production and domestic water task in central city group of Liaoning province. Recently, dozens of sewage draining exits in different sizes are constantly discharging along Hun River. Environmental monitoring communique can discover that indicators of ammonia nitrogen and COD are...
The use of Interferometric Synthetic Aperture Radar (InSAR) data has become known as an important technique for monitoring and measuring land surface deformations caused by groundwater level fluctuations. In this study, a region from the closed Konya agricultural basin is selected to infer the spatial and temporal distributions of the ground deformations using SAR images acquired by the comparatively...
Near real-time satellite data is very useful in the research and development activities for land, ocean, and atmospheric processes, environmental monitoring and assessment, weather prediction, and so on. The quality, completeness, and timeliness of this satellite data are great concerns to researchers. How to monitor and collect this information presents them with technical challenges. This paper...
Soil moisture is one of the important variables in hydrological systems. Spatial and temporal dynamics of soil moisture are important for determining complex environmental process. The aim of the study is to assess the trend of soil moisture in India and to monitor agricultural drought in Medak district of Telangana state during the period 2002 to 2014. Spatio-temporal analysis has been performed...
RADARSAT-2 SAR data were used to develop a monitoring program for Canadian forest lands with the aim to provide information on forest cutblocks and to develop algorithms for the detection of forest disturbances. Three study sites were selected in Canada and were representative of different forest types and terrain. Due to large data volumes and the need for efficiency, an automated end-to-end solution...
Locust and grasshopper plague has caused problems for man since the beginning of recorded history. In China 1.47 million ha of farmlands in 160 counties of 14 provinces suffered from oriental migratory locust L. m. manilensis attacks in summer of 2002. Among the 800 kinds of known grasshopper species habituating in China, there are 60 kinds of them are throwing a big threat to ecological environment...
