Sounds from Scientific, Meteorological and Commercial Satellites 2012-2013

This part of my audio collection is dedicated to commercial and scientific satellites. I started this separate section when Greg Roberts, ZS1BI in Cape Town, started to convert some of his old recordings from a tape recorder with elastic belt drives to electronic format. Greg is a retired professional astronomer and since 1957 has been actively involved in the tracking of artificial satellites, both by optical and radio means. Click on his picture to the right to get more information about him and his activities.

NROL-25
#38109
 (2012-014A)

FIA Radar 2 (USA 234. NROL-25) is the second of the FIA Radar satellites, and the third launch (assuming that the failed USA 193 was the first) in the Future Imagery Architecture (FIA) series. It was launched on April 3rd 2012 at 23:12 GMT on a Delta IV rocket from Space Launch Complex 6 at Vandenberg Air Force Station in California into a circular retrograde orbit with an altitude of 1080 km and an inclination of 123 degree. The satellite ceased transmissions of a continuous tone on 2242.5 MHz sometime on April 9th 2012.

Apr 3rd 2012

 

FIA (Future Image Architecture) Radar 2 was received on April 6th 2012 by Greg Roberts. He generated enclosed frequency plot versus time which allows the assessment of the doppler-shift behaviour.
There are actually four satellites in this picture:
- the satellite starting on left edge and just starting to go through time of closest approach is USA 179
- then comes the doppler curve of FIA-Radar-2
- the three parallel lines beneath USA 179 are a SDS satellite to his west - main carrier red with two sidebands
- then at right edge the bright whitish trace is the SDS satellite to his east.
The reason the intensities of the two geostationary satellites varies is because he was using a directional helical antenna to follow FIA-Radar-2. Ignore all other horizontal lines...

PROBA-V (Project for On-Board Autonomy - Vegetation) was launched on May 7th 2013 at 02:06 UTC as part of the VEGA VV02 mission as the primary payload into a 820km circular orbit.

PROBA-V is operated by ESA (European Space Agency). It is intended to be an improved smaller version of the large VGT (Vegetation) optical instrument of SPOT-4 and SPOT-5 mission and shall guarantee data continuity for the Vegetation dataset once the current Spot missions end.

PROBA-V has an S-band downlink at 2235 MHz. The  downlink mode can be switched between CCSDS BPSK @ 329900 Baud and a widseband mode. Enclosed spectrum plots show the 2 different modes. Signals were received on May 9th 2013 at 10:21 UTC and 12:03 UTC. Spectrum plots kindly provided by Paul Marsh M0EYT.

In enclosed audio file you can hear the central carrier changing frequency and thus pitch due to doppler shift. Recorded on May 9th at 12:05 UTC and kindly provided by Paul Marsh M0YET.

This audio-file and he spectrum were recorded on May 9th 2013 at 21:50 UTC at 2235 MHz when PROBA-V was in narrow mode. The receiver was tuned in the middle of the data, and what we can hear are the individual PSK carriers caused by the data modulation. Due to doppler shift it sounds like its one carrier going up and down, but in reality its many carriers passing thru the RX passband. Recording kindly provided by Paul Marsh M0YET.

The S-Band downlink on 2235 MHz of Proba-V was received and enclosed FFT plot was generated in May 2014 by Milen Rangelov.

MUOS (Mobile User Objective System) is a next-generation narrowband tactical satellite communications system designed to significantly improve ground communications for U.S. forces on the move. MUOS serves a dual-provider of both voice traffic currently routed by the Navy's existing generation, albeit aging, Ultra High Frequency Follow-On spacecraft, but it also creates a new era of mobile communications built around 3G cellular technology to relay narrowband tactical information such as calls, data messaging, file transfers and email on rates of up to 384 Kilobits per second. MUOS-2 was launched by the USA on an ATLAS V from Cape Canaveral. It is probably located on a geostationary orbit at 100° West.

MCubed-2
#39469
(2013-072H)

M-Cubed2 is a mission designed around flight evaluation of a NASA JPL image processing FPGA called COVE. The satellite provides pictures of Earth for processing, power, and data handling. M-Cubed2 is a re-flight of the COVE experiment with updated avionics after the original M-Cubed satellite accidentally docked with another cubesat shortly after launch, losing the ability to transmit in the process. MCubed-2 transmits telemetry every 10 seconds in 9600bps GMSK at 437.485 MHz. Antenna polarization is linear.

IPEX
CP-8
#39471
(2013-072K)

IPEX (Intelligent Payload Experiment) is a Cubesat built by the Californoa Polytechnic State University. Its mission is to demonstrate operation of autonomous instrument processing, downlink operations, and ground station operations, utilizing the SpaceCube Mini payload processing unit to validate a reduction in data product downlink. IPEX transmits on 437.320 MHz 9600bps GMSK and CW mode.

#39492
(2013-078C)

AIST-1 is a russian microsatellite developed by a group of students, postgraduates and scientists of Samara Aerospace University in cooperation with TsSKB-Progress. The satellite will measure the geomagnetic field, test the new small space vehicle bus, test methods to decrease microaccelerations to a minimum level and measure micrometeoroids of natural and artificial origin. It features uplink antennas for 145 MHz and downlink antennas for UHF.

AIST-1 transmits a CW beacon on 435.265 MHz using the callsign RS41.
