Special Issue Information

Dear Colleagues,

The use of unmanned flight systems has increased in recent years and currently includes many different areas of application. Drones are used, for example, for video surveillance and visual observation of systems and infrastructures, and has been established for measuring meteorological parameters. In comparison, environmental monitoring with miniaturized devices or special detection systems installed on drones is a young discipline, but it promises a very high level of flexibility regarding the choice of place of use and of measurement parameters, as well as rapid operational readiness in contrast or in support to ground-based and permanently installed measuring devices. The miniaturization of high-quality measurement technology is increasingly opening up opportunities to use drones to record environmental parameters and pollutants. Many of application examples are subjects of current research. This Special Issue of Sensors aims at collecting original research papers to contribute to the discussion on the use of drones in the field of environmental monitoring: It includes the following (but is not limited to them):

  • Radioactivity measurements
  • Smoke, Aerosol and bio-aerosol measurements
  • Measurements of hazardous substances in the air as well as on difficult to access grounds
  • Measurements of meteorological parameters and air quality
  • Agriculture applications
  • Gas and particle measurements on volcanoes
  • Data management, transfer, visualization of measurements with drones
  • Post processing and data assimilation
  • Miniaturization of reference methods for use on drones

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Rapid and accurate reconnaissance in the event of radiological and nuclear (RN) incidents or attacks is vital to launch an appropriate response. This need is made stronger by the increasing threat of RN attacks on soft targets and critical infrastructure in densely populated areas. In such an event, even small radioactive sources can cause major disruption to the general population. In this work, we present a real-time radiological source localization method based on an optimization problem considering a background and radiation model. Supported by extensive real-world experiments, we show that an airborne system using this method is capable for reliably locating category 3–4 radioactive sources according to IAEA safety standards in real time from altitudes up to 150 m. A sensor bundle including a LiDAR sensor, a Gamma probe as well as a communication module was mounted on a UAV that served as a carrier platform. The method was evaluated on a comprehensive set of test flights, including 28 flight scenarios over 316 min using three different radiation sources. All additional gamma sources were correctly detected, multiple sources were detected if they were sufficiently separated from each other, with the distance between the true source position and the estimated source averaging 17.1 m. We also discuss the limitations of the system in terms of detection limit and source separation. Full article
