“…Substation is often threatened by various threats, mainly including radio frequency (RF) interference, illegal unmanned aerial vehicle (UAV) invasion, vehicle invasion, and so on. The threat of RF interference to substation mainly includes two parts: the first is GNSS frequency interference, resulting in satellite positioning signal failure [1,2]; second, the power grid RF communication interference, which means internal communication distortion, command and dispatch failure [3,4]; the threat of illegal UAV, that is someone use UAV to peep at the internal situation of substation, to damage internal facilities and other illegal activities, and it will result in serious problems, such as substation facilities damage or even substation paralysis [5,6]; the invasion of people, vehicles and objects is the cross-border invasion of personnel, vehicles and various objects in the protection area around the substation, often resulting in abnormal operation of the substation and even equipment failure.…”

The above article from IET Circuits, Devices & Systems, published online on 14 September 2022 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the Editor‐in‐Chief, Harry E. Ruda, the Institution of Engineering and Technology (the IET) and John Wiley and Sons Ltd. This article was published as part of a Guest Edited special issue. Following an investigation, the IET and the journal have determined that the article was not reviewed in line with the journal’s peer review standards and there is evidence that the peer review process of the special issue underwent systematic manipulation. Accordingly, we cannot vouch for the integrity or reliability of the content. As such we have taken the decision to retract the article. The authors have been informed of the decision to retract.

“…For this reason, several proposals to NASA and ESA have been already submitted to select the successors of these instruments. Some notable proposals include: THESEUS [238], SVOM [28], e-ASTROGAM [85], AMEGO-X [52] and several CubeSats missions [40,97] (BlackCAT [92], BurstCUBE [201], COMCUBE [154], COMPOL [271], CUSP [91], EIRSAT-1 [185], GRID [265], GRBAlpha [194], GTM [56], IGOSat [204], IMPRESS [230], LECX [45], LIGHT-1 [13], MAMBO [39], MeVCube [163], Min-XSS1 [169], Min-XSS2 [170], SOCRATES [77], VZLUSAT-2 [216]).…”

EXACT and SOCRATES are a pair of CubeSats being developed to advance the TRL of a dual-use sensor. It can function either as x-ray detector used for characterization of high energy photons or as a sensor for measuring relative ranges between users in deep space operations. The ranging function of the sensor is described in this paper. After describing the measurements generated by the sensor, the algorithms that make use of this information to generate a position solution are presented. As a validation case study, data from the Japanese spacecraft Suzaku's observation of the Crab Nebula Pulsar is used to estimate the spacecraft's change in position along the line-of-sight to the pulsar, using this estimation scheme. Suzaku's observations are suitable for this application because the spacecrafts Hard X-Ray Detector (HXD) is similar in effective surface area to the prototype X-Ray/gamma-ray detector currently under development for use onboard EXACTand SOCRATES. Thus, validation of this technique using data from Suzaku serves to verify the feasibility of this navigation technique onboard other spacecraft with detectors of similar size.
