Jakarta Lightning Detection System

2019 International Conference on Electrical Engineering and Informatics (ICEEI), 2019
Lightning is a serious problem for modern community. Direct lightning stroke can damage or destroy an obect and hurt or even kill a living thing. Indirect lightning stroke can damage elecronic and microcontroller stuff because it has very small or thin insulation.

The Detection of Continuing Current in Lightning Using the Geostationary Lightning Mapper

Journal of Geophysical Research: Atmospheres, 2022
AbstractLightning with continuing current may have current durations that last for hundreds of milliseconds, resulting in continuous optical emission that coincides with the uninterrupted current flow. The space‐based Geostationary Lightning Mapper (GLM) is an optical sensor that allows for the detection of continuous optical emission.

Observation of Lightning Discharges in Indonesia by Lightning Detection Network

2006 IEEE 8th International Conference on Properties and applications of Dielectric Materials, 2006
A real-time lightning location network started to operate in Indonesia in mid 1995 and began providing reliable data in the end of the same year. The network consists of 8 signal receiving stations and works using the Time-Of-Arrival (TOA) technique.

FORTE radio‐frequency observations of lightning strokes detected by the National Lightning Detection Network

Journal of Geophysical Research: Atmospheres, 2000
This work compares simultaneous observations of lightning from two complementary systems. FORTE is a low‐Earth‐orbit satellite carrying radiowave and optical instruments for the study of lightning. The radio receivers aboard FORTE observe very high frequency (VHF) emissions from the air‐breakdown process preceding (and sometimes accompanying) a ...

Optical Detection of Lightning on Venus

Icarus, 1995
Abstract The night side of Venus was imaged at 18.8 frames per second using coronagraphic optics and a 153-cm telescope during the spring 1993 apparition in a search for lightning. The images were then reduced such that scattered light from the day side was removed and transient signals were sought.

Detection of lightning superbolts

Journal of Geophysical Research, 1977
Unusually intense lightning strokes have been observed by optical sensors on the Vela satellites. These lightning flashes are over 100 times more intense than typical lightning. The lightning superbolts are characterized by optical power in the range of 1011–1013 W, have a duration of the order of 1 ms, and have a total radiant energy greater than 109 ...

Revisiting the Detection of Lightning Superbolts

2020
This study uses Fast On-Orbit Detection of Transient Events (FORTE) satellite observations to identify superbolt-class optical lightning events and evaluate their origins. Superbolts have been defined by Turman (1977) as lightning pulses whose peak power exceeds 10 W.

Lightning Detection with SPICE

The Physics Teacher, 2018
Electrical engineers often use software to analyze electrical circuits in order to understand circuit behaviors. Such software allows them to modify components and develop and improve their designs. One popular kind of circuit analysis software is based on SPICE (Simulation Program with Integrated Circuit Emphasis).
