--------------------------------------Chinese Satellite Profiles RF Spectrum as Seen from Lunar Orbit
The Chinese DSLWP-B (LO-94) satellite that had been in lunar orbit
provided a profile of Earth’s HF spectrum as seen from the moon. The
microsatellite subsequently was crashed into the moon’s surface after
having completed its mission. DSLWP stands for “Discovering the Sky at
Longest Wavelengths Pathfinder.” Among other things, DSLWP-B was de-
signed to test low-frequency radio astronomy and space-based interfer-
ometry, and it carried Amateur Radio and educational payloads.
The HF spectrum mission included mapping “RF interference” from Earth
in the 1 – 30 MHz range by studying its occlusion by the moon during
lunar orbit. According to Chinese media accounts, this was done to
“verify the technology of ultra-long wave astronomical observation and
solar radiation research.” The onboard detector sensed the spectrum of
RF radiation at different positions of the lunar orbit.
The Harbin Institute of Technology (BY2HIT) developed and built the
DSLWP spacecraft and oversaw the mission. The microsatellite also
carried optical cameras from Saudi Arabia.
In July, a contact between radio amateurs in Germany and China took
place on July 1 via LO-94. The two-way exchange was between Reinhard
Kuehn, DK5LA, in Sörup, Germany, and Harbin Institute of Technology
club station BY2HIT (operated by Wei Mingchuan, BG2BHC), in Harbin,
China, via the onboard GMSK-to-JT4G repeater — the first such contact
ever made.
