B. Text of Launch Announcements.

Kompsat 2,
also known as Arirang 2 EO, is a South Korean (KARI)
remote sensing craft that was launched by a Rokot rocket (a modified
ICBM, SS-19) from Plesetsk at 07:05 UT on 28 July 2006. The 800 kg
craft carries imaging systems to yield high-resolution,
multispectral images of Earth’s surface. The initial orbital
parameters were period 98.6 min, apogee 680.9 km, perigee 656.3 km,
and inclination 98.1°.
Cosmos 2422
is a Russian military satellite that was launched by
a Molniya-M rocket from Plesetsk at
04:20 UT on 21 July 2006. Initial orbital parameters were period
703.9 min, apogee 39,134 km, perigee 534 km, and inclination 62.8°.
Genesis 1
is an American entrepreneur’s inflatable satellite that was
launched by a Dnepr rocket (a converted ICBM, known as SS-18 Satan)
at 12:53 UT on 12 July 2006 from the southern Ural mountain. The
1,300 kg craft was successfully inflated about two hours after
launch to its normal cylindrical size of 2.4 m x 4.5 m. It is made
of a tough sheet fabricated from a composite Kevlar that is often used
in bullet-proof vests. The goal of the entrepreneur is to launch a
few more of them, string them together and
promote “space tourism”. The initial orbital parameters were period
95.8 min, apogee 561 km, perigee 556 km, and inclination 64.5°.
STS 121
is an American shuttle craft that was launched from Cape
Canaveral at 18:38 UT on 04 July 2006, carrying seven astronauts to
the International Space Station, ISS. It was the first flight after
the fleet was grounded a year ago to make safety-related
modifications to the external, cryogenic fuel tank. This time the
take-off was nominal with no significant thermal shield degradation.
It carried 12 tonnes of food, fuel, and equipment to the ISS. It
docked with the ISS at 14:52 UT on 06 July 2006. During the 12-day
mission, the astronauts tested new equipment and procedures aimed at
increasing shuttle safety. They deployed the ISS robotic arm, with
its attached camera, to examine the exterior of the shuttle for
damage; none of significance was noticed. Two of the astronauts
did a 6.5-hour spacewalk to test the capability of the 30-meter
robotic arm to repair any damage to the shuttle’s exterior. The crew
also carried out 21 biological and technical experiments on-board.
STS 121 landed back in Cape Canaveral on 17 July, at 13:14 UT,
leaving behind at the ISS the ESA astronaut to spend several months
at the station. The initial parameters were period 91.4 min,
apogee 351 km, perigee 332 km, and inclination 51.6°.

C. Spacecraft Particularly Suited for International Participation

Spacecraft with essentially continuous radio beacons on frequencies
less than 150 MHz, or higher frequencies if especially suited for ionospheric
or geodetic studies.

NNSS denotes U.S. Navy Navigational Satellite System. Updates or
corrections to the list are possible only with information from the
user community.

The full list appeared in SPX 545.
The list will not be repeated in future issues until significantly revised

Global Positioning System satellites useful for navigational
purposes and geodetic studies.

High precision (<20 cm) GPS constellation tracking data obtained from
the network of about 80 dedicated global stations that are of interest to
geodetic study may be obtained through the following services provided
by the International Association of Geodesy (IGS)

     FTP:  [directory /igscb]

The standard format of the GPS situation appeared in SPX-518. It will not
be repeated since an excellent source of trajectory- and science-related GPS information is at:

It provides many links to GPS related databases.

The latest addition to the fleet is Navstar 57, 2005-038A.

Russian Global Navigational (Positioning) Spacecraft, GLONASS

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 (NNNN)
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

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

The standard format of the GLONASS situation last appeared in
SPX-545. It
will not be repeated in view of the excellent updated source at:
maintained by the Coordinational Scientific Information Center (CSIC), Russian
Space Forces.

According to CSIC the
latest addition to the fleet are GLONASS 712, GLONASS 796, and GLONASS 797.
Their International IDs are 2005-050A, 2005-050B, and 2005-050C.
