German for lightning (Blitz) locating (Ortung)
Time-of-arrival. The and almost all commercial lightning detection networks uses the TOA method for accurate locating of lightning strokes. more
Direction-Finding. A method for locating lightning strokes. Not as accurate as the TOA-method. more
Electric field. The counterpart of the H-field in an electromagnetic field.
Magnetic field. The counterpart of the E-field in an electromagnetic field. Can be detected with magnetic field antennas, like loop or ferrite antennas.
Global Positioning System. A satellite navigation system that provides location and time information anywhere on the Earth. Maintained by the United States government.
Global Navigation Satellite System. A system that uses satellites to provide autonomous geopositioning like GPS, Galileo, GLONASS or Beidou.
Satellite-based augmentation system. Improves the navigation system's accuracy through the integration of external information into the calculation process. These external information are broadcasted to the GPS receivers by satellites.
One pulse per second. A very accurate pulse from the GPS module which can be used for exact absolute time measurements. That means, all clocks of all world-wide stations show the same time with a deviation of a few dozen nanoseconds. This is essential for the TOA method. ADC or A/D Analog-to-digital converter. Converts a continuous voltage to a digital number.
Microcontroller unit. A small computer on an integrated circuit containing a processor core (CPU), memory and peripherals.
Printed Circuit Board
Coordinated Universal Time which is equal to Greenwich Mean Time (GMT). All time stamps used for computing the lightning data use UTC as time base.
Very low frequency. Radio frequencies in the range of 3 kHz to 30 kHz or wavelengths from 10 to 100 kilometers. The most powerful emissions of lightning discharges occur in the VLF range.
An abbreviation for radio atmospheric signal. It is a broadband electromagnetic impulse which occurs as a result of lightning discharges.
