Remote sensing applications like disaster or mass event monitoring need the acquired data and extracted information within a very short time span. Airborne sensors can acquire the data quickly and on-board processing combined with data downlink is the fastest possibility to achieve this requirement. For this purpose, a new low-cost airborne frame camera system has been developed at the German A...

This paper describes the latest developments in the wide area monitoring of electrical power grids, based on IEEE C37.118.1-2011 synchrophasor measurements. It outlines the fundamentals of synchrophasor systems, and focuses on the latest technological advancements and practical applications deployed in the existing and emerging power grids. With the emphasis on higher utilization of power syste...

Sensors like current transformers and voltage transformers are used to monitor the power systems and data from these sensors are collected in appropriate computer applications to observe the state of the power system. Phasor Measurement Units (PMUs) get data from current and voltage transformers and time-stamp them thereby paving the way for wide-area monitoring of the power system. In wide-are...

The persistent scatterer interferometry (PSI) is a well established monitoring technique for urban areas. It has been updated in order to process wide areas with the accepted characteristics in precision and resolution. Of course, the covered processing area now includes rural areas with a low persistent scatterer (PS) density. In order to bridge forested areas and water bodies, low quality and...

Performance problem diagnosis is a critical part of network operations in ISPs. Service providers typically deploy monitoring nodes at several vantage points in their network, to record end-to-endmeasurements of network performance. Network operators use these measurements offline; for example, to troubleshoot customer complaints. In this work, we leverage such monitoring infrastructure deploym...
