Instrumentation for space-based low frequency radio astronomy
2000This paper will provide a general overview of the techniques that have been used to measure low frequency radio waves. It will first cover basic antenna systems and problems associated with their implementation on a spacecraft. Then a discussion of receiver types and measurable parameters will follow. Resolution and precision will be addressed.

Receiver System Design for Low Frequency Radio Astronomy Applications
2018 2nd URSI Atlantic Radio Science Meeting (AT-RASC), 2018Over the past two decades we have seen an emergence of low frequency (sub 500MHz) radio interferometers which fit the description of Large N arrays including the proposed Square Kilometre Array (SKA) [1] and the Hydrogen Epoch of Reionization Array (HERA) [2] telescopes.

The current status of low frequency radio astronomy from space
2000Ground-based radio astronomy is severely limited by the Earth's ionosphere. Below 15 - 20 MHz, space-based radio observations are superior or even mandatory. Three different areas of astronomical research manifest themselves at low radio frequencies: solar, planetary, and galactic-extragalactic.

A satellite-borne receiver for low-frequency radio astronomy
Radio and Electronic Engineer, 1968A receiver designed to measure the galactic noise spectrum in the range from 2 to 4.5 MHz and flown in the Ariel III satellite is described. Problems arising from the use of a loop antenna with a swept receiver and the exclusion of spurious signals from terrestrial sources and other experiments in the payload are discussed. Preliminary results indicate

MASER: a toolbox for low frequency radio astronomy
2018The MASER (Measuring, Analysing and Simulating Radio Emissions) project provides a comprehensive infrastructure dedicated to low frequency radio emissions (typically < 50 to 100 MHz). The four main radio sources observed in this frequency are the Earth, the Sun, Jupiter and Saturn. They are observed either from ground (down to 10 MHz) or from space.

Goniopolarimetric techniques for low-frequency radio astronomy in space
2013The principles of space-based low-frequency radio astronomy are briefly introduced. As the wavelength range considered does not allow the use of focusing systems, goniopolarimetric (or “direction-finding”) techniques have been developed. These techniques are presented, and their limitations are discussed. An example from a recent study on auroral radio

An evolutionary sequence of low frequency radio astronomy missions
2008A progression from simple, near-term experiments to Explorer-class dedicated missions to a large lunar faxside array is a natural way to develop the observational capabilities needed for radio astronomy at low frequencies. This continuous increase in mission capabilities and scientific return is similar to the progression of infrared and X-ray missions.

Low-frequency radio astronomy and the origin of cosmic rays
2000One of the longest standing mysteries in physics and astronomy is the origin of cosmic rays. Space-based low-frequency radio astronomy holds the promise of providing answers to key pieces of this important puzzle. There are a number of important reasons why the study of Galactic low frequency emission will offer new insights into this 87 year-old ...
