First Radar -- CubeSat Transionospheric HF Propagation Observations: Suomi 100 Satellite and EISCAT HF Facility
Esa Kallio, Antti Kero, Ari-Matti Harri +14
Radio waves provide a useful diagnostic tool to investigate the properties of the ionosphere because the ionosphere affects the transmission and properties of High Frequency (HF) e…
Eastward-expanding auroral surges observed in the post-midnight sector during a multiple-onset substorm
Yoshimasa Tanaka, Yasunobu Ogawa, Akira Kadokura +9
We present three eastward-expanding auroral surge (EEAS) events that were observed intermittently at intervals of about 15 min in the post-midnight sector (01:55-02:40 MLT) by all-…
Severe and localized GNSS scintillation at the poleward edge of the nightside auroral oval during intense substorm aurora
Christer van der Meeren, Kjellmar Oksavik, Dag A. Lorentzen +2
In this paper we study how GPS, GLONASS, and Galileo navigation signals are compromised by strong irregularities causing severe phase scintillation ( > 1) in the ni…
Nanodust detection between 1 and 5 AU by using Cassini wave measurements
P. Schippers, N. Meyer-Vernet, A. Lecacheux +6
The solar system contains solids of all sizes, ranging from km-size bodies to nano-sized particles. Nanograins have been detected in situ in the Earth's atmosphere, near cometary a…
Cavitating Langmuir Turbulence in the Terrestrial Aurora
B. Isham, M. T. Rietveld, P. Guio +3
Langmuir cavitons have been artificially produced in the earth's ionosphere, but evidence of naturally-occurring cavitation has been elusive. By measuring and modeling the spectra…
Polyphase alternating codes
Markku Markkanen, Juha Vierinen
This work introduces a method for constructing polyphase alternating codes in which the length of a code transmission cycle can be or , where is a prime number and $…
