10craft that were launched by the PSLV-C9. It, however, remained
attached to the final stage, as has been the case of previous Rubin
spacecraft. The initial orbital parameters were period 97.5min, apogee
662km, perigee 619km, and inclination 98.9°.

2008-021C, 2008-021D, 2008-021E, 2008-021F, 2008-021G, 2008-021H, 2008-021J
These seven nanosatellites are yet to be matched with their names. They
were all launched by a PSLV-C9 rocket from Sriharikota at 03:54UT on
28April 2008. The first six in the list will be clustered and
collectively named NLS-4. The orbital parameters of all seven were
similar: period 97.2min, apogee 634km, perigee 616km, and inclination
98°. The following are skeleton descriptions of these nanosatellites:

CartoSat2A is the primary Indian remote sensing craft among the
fleet of 10satellites that were launched by a PSLV-C9 rocket from
Sriharikota in southeastern coast of India at 03:54UT on 28April 2008.
The 690kg, 900W, triaxially stabilized craft carries a panchromatic
camera to provide 0.5-0.85micron images at one meter resolution in a
swath of 9.6km. It can be steered along track as well as across track to
enable repeated images of a chosen site, frequently. The images will be
used in rural and urban planning. The initial orbital parameters were
period 97.3min, apogee 637km, perigee 616km, and inclination 98°.

2008-020A
GIOVE-B (Galileo In-Orbit Validation Element-B) is the second of the
test versions of the 30craft European Union navigational fleet that is
planned to be launched beginning 2010. It was launched by a Soyuz-Fregat
rocket from Baikonur at 22:16UT on 26April 2008. (A similar version,
GIOVE-A, was launched in December2005.) The 500kg craft carries two
(redundant) Rubidium atomic clocks, and an even more precise Passive
Hydrogen Maser with an accuracy of onenanosecond/day. It also carries a
radiation-monitoring payload, and a laser retro-reflector for
high-accuracy laser ranging. When completed, this Galileo fleet will
become the third available fleet, after the long-functional GPS and the
to-be-completed GLONASS fleets. The initial orbital parameters were
period 842min, apogee 23,154km, perigee 23,015km, inclination 56°.

2008-019A
Tianlian 1 is the first data-relay satellite of China that was
launched by a Long March3C rocket from Xichang satellite Launch Center
in Sichuan province at 15:35UT on 25April 2008. Its operation will be
activated with the launch of the manned Shenzhou7 mission later in 2008.
It will then cover about 50% of Shenzhou7 orbit, rather than the
coverage of 12% without the relay. (USSTRATCOM names the satellite as
CTDRS.) The initial orbital parameters were period 752min, apogee
41,795km, perigee 210km, and inclination 18.5°.

2008-018B
Star One C2 is a Brazilian geostationary communications satellite
that was launched by an Ariane5ECA rocket from Kourou at 22:17UT on
18April 2008. The 4.1tonne (with fuel) craft carries a total of
45transponders in C-, Ku-, and X-bands to provide direct-to-home TV and
telephony for Brazil and Mexico after parking over 65°W longitude.

C/NOFS (Communication/Navigation Outage Forcasting System) is an
American military satellite that was launched by a Pegasus rocket
released from a L-1011 aircraft flying out of Reagan Test Site at
Kwajalein in Marshal Islands at 08:00UT on 16April 2008. The 395kg craft
will monitor the conditions that lead to the generation of
irregularities/bubbles that produce radio scintillations in the
equatorial ionosphere and to warn against imminent
disruption/degradation of military communications. It carries an
instrument called CINDI (Coupled Ion Neutral Dynamic Investigation)
consisting of an Ion Velocity Meter , a Neutral Wind Monitor , and a
Vector Electric Field Instrument . CINDI is a NASA-sponsored
investigation. (See . The
initial orbital parameters were period 97.3min, apogee 853km, perigee
405km, and inclination 13°.

2008-016A
ICO G1 is an American (ICO Global Communications, Inc.)
geostationary communications satellite that was launched by an Atlas5
rocket from Cape Canaveral at 20:12UT on 14April 2008. The 6.6tonne
(with fuel), 16kW craft carries an unfurlable, 12m diameter S-band mesh,
and is 30m long including the solar panels. It will operate in 2.0GHz
band with seven C-band transponders, providing voice video, and internet
services directly to mobile platforms in North America, after parking
over 92.9°W. Although 99% of its population are adequately served by the
cell phone networks, the roadside services are unavailable in 33% of the
area; this will be met by the geostationary craft. It utilizes a GBBF
(Ground-Based Beam Forming system) which allows 250 transmitting and 250
receiving independent S-band beams.

2008-015A
Soyuz TMA-12 is a Russian passenger transport craft that was
launched by a SoyuzFG rocket from Baikonur at 12:17UT on 08April 2005.
It carried three astronauts (two Russian and one South Korean) to the
International Space Station and docked automatically with it at 16:00UT
on 10April 2008. After about 10days at the ISS, the South Korean
astronaut and two other astronauts who had been staying on the ISS for
several months, returned to Earth on 19April on SoyuzTMA-11 (that had
remained docked at the ISS since its mission in October2007). It was a
rough landing at a location 400km away from the planned location. The
initial orbital parameters of TMA-12 were period 91.4min, apogee 347km,
perigee 337km, and inclination 51.6°.

C. Spacecraft Particularly Suited for International Participation

BulletinA monthly publication of the National Space Science Data
Center/World Data Center for Satellite InformationNo. 65401 May 2008

Russian Global Navigational (Positioning) Spacecraft, GLONASS constellation.

SPACEWARN requests updates/additions from readers to this list.

All GLONASS spacecraft are in the general Cosmos series. The Cosmos
numbers invoked by USSPACECOM have often differed from the numbers
associated in Russia; when different, the USSPACECOM Cosmos numbers are
shown in parentheses. The corresponding GLONASS numbers are Russian
numbers, followed by the numbers in parentheses that are sometimes
attributed to them outside Russia.

The operating frequencies in MHz are computed from the channel number K.
Frequencies = 1602.0 + 0.5625K and L2 = 1246.0 + 0.4375K.

The standard format of the GLONASS situation last appeared in SPACEWARN
Bulletin No.545. It will not be repeated in view of the excellent
updated source at: maintained by the
Coordinational Scientific Information Center , Russian Space Forces.

According to CSIC the latest additions to the fleet are 2007-065A,
2007-065B, and 2007-065C.
