Sounds from Space

 

Sounds from Scientific, Meteorological and Commercial Satellites 1996-2005

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.

Microsat
#24291
(1996-050A)

MuSat - 1 "Victor" was developed and built by a 25-person team at the Instituto Universitario Aeronautico, under the Sponsorship of the government of the province of Cordoba. MuSat-1 was launched together with Magion-5 and Prognoz M-2 by a Molniya-M rocket from Plesetsk cosmodrome. It was the first satellite made in Argentina and the 340x340x450mm Microsat was reported to be functional. "Victor " is an experimental vehicle, intended to evaluate in-orbit behavior of low-cost space technologies. It carries two video cameras, oriented for earth-imaging, as well as transceivers in both UHF and S bands. Electrical power is provided by four 88-Si cells solar panels, with an end-of-life electrical power of 8W. It finally decayed on the November 12th 1999.

INMARSAT 3F2
I3F2
AOR-E
#24307
(1996-053A)

Inmarsat 3F2 was built by Lockheed Martin and is based on their GE-4000 platform. It was launched without a apogee kick motor from Baykonur on a Proton-K/DM-1 launcher (#243) and was thus directly injected into a GSO. It geostationary orbit position was finally at 15.5° West.

Inmarsat 3-F2s primary mission is to supply voice and data communications services worldwide to mobile terminals such as small as pocket-size messaging units on ships, air-crafts and vehicles. It can dynamically reallocate both RF power and bandwidth among a global beam and seven spot-beams, allowing greater reuse of the available spectrums. The spot-beams are directed as required to make extra communications capacity available in areas where demand from users is high. Its main transponder is an L-Band transponder (1.6/1.5 GHz) using two 2m big dish based circular polarized antennas for up- and down-link. You can see the 2 dishes in the lower left picture. EIRP on L-Band is up to 48dBW. Its forward bandwidth is 29 MHz, its return bandwidth is 39 MHz. In addition it features a C-Band transponder (6.4/3.6 GHz) also using circular polarized antennas Its bandwidth
there is 39 MHz.

Furthermore I3F2 is also part of the EGNOS satellite based augmentation system (SBAS). Its carries a navigation transponder designed to enhance the accuracy, availability and integrity of the GNSS (GPS and Glonass) global navigation satellite systems.

Iridium 8
 
#24792
(1997-020A)

The IRIDIUM satellite system provides worldwide voice and data coverage including remote areas. When a subscriber is in a remote area his handset will operate through the satellite network whereas it will use terrestrial networks wherever available. The satellite system is based on 66 active satellites in low Earth circular orbits with an altitude of 780km and an inclination of 86.4°. Originally the constellation should have consisted of 77 active satellites and thus the name of the 77th element in the periodic table "Iridium" was chosen. The communication system uses a combined FDMA/TDMA approach. The communication to the terminals is in the frequency range of 1616-1626,5 MHz. Up- and Downlinks to the basestations and gateways as well as inter-satellite links operate in the frequency ranges 19,4-19,6 GHz and 29,1-29,3 GHz. The special shape of the antennae and solar panels can create strong reflections of the sunlight known as Iridium flares. You can calculate possible visible flares by clicking on the picture to the right.

Circular panels hinged from each side after launch to expose solar cells. These panels tilted  in one axis to track the sun and provide 160W electrical power. FM-08 was launched in a stack of 8 Microstar / Orbcomm satellites with a Peagasus rocket which was dropped my an airplane. The deployed spacecraft measured 3.6 m from end to end with 2.3 m span across the circular disks. VHF telemetry was at 57.6 kbps. The spacecraft carried 17 data processors and 7 antennas and was designed to handle 50,000 messages per hour. The long boom was a 2.6 meter VHF/UHF gateway antenna. Receive: 2400 bps at 148 - 149.9 MHz. Transmit: 4800 bps at 137 - 138 MHz and 400.05 to 400.15 MHz. The system used X.400 (CCITT 1988) addressing. Message size was 6 to 250 bytes typical (no maximum).

(2004-052A)

Sich 1M is a Russo-Ukrainian Earth surveying mini-satellite that was launched by a Tsyklon 3 rocket from Plesetsk at 11:20 UT on December 24th 2004. Unfortunately SICH-1M did not reach the final orbit due to a malfunction of the 3rd stage of the rocket. It carried imaging instruments to survey the surface environment and locate natural disasters. Sich is the Ukrainian name for owl. Downlinks were at 137.400 MHz, 466.5 MHz and 460.03 MHz. SICH-1M stopped operations on August 8th 2005 and re-entered.

IRS-P5
Cartosat-1
#25758
(2005-017A)

CartoSat-1 or IRS P5 (Indian Remote Sensing Satellite) was built by ISRO and is mainly intended for cartographic applications. It is the eleventh satellite built in the Indian Remote Sensing (IRS) satellite series and was launched into a 618 km high polar Sun Synchronous Orbit (SSO) by PSLV-C6. It carries two Panchromatic (PAN) cameras that take black and white stereoscopic pictures of the earth in the visible region of the electromagnetic spectrum. The swath covered by these high resolution PAN cameras is 30 km and their spatial resolution is 2.5 meters. It facilitates the generation of accurate three-dimensional maps. The images taken by CartoSat-1 cameras are compressed, encrypted, formatted and transmitted to the ground stations where the images are reconstructed from the data received.
