(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.
The recorded beacon, which can be heard every
90 seconds on 137.95 MHz as a brief burst of CW "Hi

INMARSAT

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-F2’s 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

#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

ORBCOMM FM-8 is part
of a commercial venture to provide global messaging
services using a constellation of 26 low-Earth orbiting
satellites. The spacecraft was a circular shaped disk.
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

Orbcomm is a commercial
global wireless data and messaging system. The Orbcomm
System uses low-Earth orbit (LEO) satellites to provide
cost-effective tracking, monitoring and messaging capabilities
to and from anywhere in the world. Similar to two-way
paging or e-mail, the system is capable of sending and
receiving two-way alphanumeric packets of data. These
short, economical messages increase the efficiency of
remote operations by making critical information readily
available, often from areas beyond the geographic and
economic reach of traditional systems.
The Orbcomm constellation
consists of up to 36 small communications satellites
in orbit 825 kilometers above the Earth. The satellites
act as “orbiting packet routers” built to “grab” small
data packets from ground sensors or communicators and
relay them through a ground station.
Orbcomm satellites
have also been used for relaying messages from orbit
to the ground from Rubin test satellites. |

The instruments consist of the European (x-ray) Photon
Imaging Cameras (EPIC), the Reflection Grating Spectrometers
(RGS), and the Optical Monitor. Among the goals
for the 10 year lifetime of XMM are: understanding the
diffuse x-ray background, mapping the x-ray emitting
gas in clusters of galaxies, unbiased surveys of galaxies
and of stars, diagnostic studies of accreting binary
stars, temporal spectroscopic studies of AGN's and spectral
studies of supernove remnants in nearby galaxies. |

GLONASS (Globalnaya
Navigationnaya Sputnikovaya Sistema, Global Orbiting
Navigation Satellite System) is a Soviet space-based
navigation system comparable to the American GPS system,
which consists of Uragan spacecraft. The operational
system contains 21 satellites in 3 orbital planes, with
3 on-orbit spares. GLONASS provides 100 meters accuracy
with its C/A (deliberately degraded) signals and 10-20
meter accuracy with its P (military) signals.
The Uragan spacecraft
are 3-axis stabilized, nadir pointing with dual solar
arrays.
The payload consists
of L-Band navigation signals in 25 channels separated
by 0.5625 MHz intervals in 2 frequency bands: 1602.5625
- 1615.5 MHz and 1240 - 1260 MHz. EIRP 25 to 27 dBW.
Right hand circular polarized. On-board caesium clocks
provide time accuracy to 1000 nanoseconds.
Cosmos 2395 is one
of three Glonass fleet spacecraft that was launched
by a Proton-K rocket from Baikonur at 07:38 UTC on December
25th 2002.
They extend the current, depleted fleet of nine spacecraft
to 12, which will grow further to a fleet of 18 spacecraft
by 2004, and to 24 by 2005. The original fleet had 24
spacecrafts in the 1980s. |

detect disturbances in the solar wind by means of imaging
scattered light from the free electrons in the plasma
of the solar wind. To do this three CCD cameras observe
sections of the sky of size 60 by 3 degree. Data
will be stored onboard and downlinked to dedicated ground
stations in x-band. Reported downlink frequencies in

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
