Abstract
The Extremely Low Frequency (ELF) and Very Low frequency (VLF) technique are useful for studying the lower
ionosphere of the Earth. Exploring this region has been begun in Viet Nam. We constructed the ELF/VLF remote sensing with low
cost. This system includes a loop antenna, a pre-amplifier, a sound card, a PC with software and a GPS receiver. After surveying
its characteristics, we found that the antenna has the high sensitivity and the pre-amplifier designed has the flat frequency response
with frequency from 1 kHz to 20 kHz. It can record sferics generated by lightning discharges to estimate the parameters of the
nighttime D-region ionosphere. It is also a teaching module to educate students in Space physics.
