| 2003-010A | Navstar 52, also known as USA 168 and as GPS 2R-9, is an American Global Positioning Satellite that was launched by a Delta 2 rocket from Cape Canaveral AFS at 22:09 UT on 31 March 2003. It will replace the aging GPS 2-5 in the fleet (of 28 satellites). Sec. C-2 below provides more information on the fleet. The initial orbital parameters were period 355.6 min, apogee 20,228.8 km, perigee 187.83 km, and inclination 39.0°. |
|---|---|
| 2003-009A, 2003-009B | IGS 1A (Information Gathering Satellite 1A) and IGS 1B are two Japanese reconaissance satellites that were launched by as H-2A rocket from Tanegashima Space Center at 01:27 UT on 28 March 2003. They may be used to monitor for nuclear explosions and missile launches in nearby countries in addition to global natural disasters and hurricanes. As such, according to the Japanese Defense Ministry, the launch is not in violation of the Japan-N. Korea declaration of September 2002. One of the two spacecraft uses optical cameras with a resolution of one meter; the other uses synthetic aperture radar to provide images at a resolution of a few meters. No information is available as to which satellite carries which instrument. Initial orbital parameters of both were close: period 94.4 min, apogee 490.9 km, perigee 485.5 km, and inclination 97.3°. |
| 2003-008A | USA 167, also known as DSCS 3A3, is an American geostationary military communications spacecraft of the DSCS 3 constellation that will provide very secure global links to the military. It was launched by a Delta 4 rocket from Cape Canaveral AFS at 00:59 UT. These DSCS 3 spacecraft are triaxially-stabilized spacecraft with solar power of 1.24 kW. They operate at six SHF frequencies between 40 and 85 MHz. The parking longitude is unavailable. |
Note: The full list appeared in SPX 545. The list will not be repeated in future issues until significantly revised again.
High precision (<20 cm) GPS constellation tracking data obtained from the network of about 400 dedicated global stations that are of interest to geodetic study may be obtained through the following services provided by the International GNSS Service (IGS). The IGS is a service of the International Association of Geodesy (IAG).

The standard format of the GPS situation appeared in SPACEWARN Bulletin No. 518.
It will not be repeated since an excellent source of trajectory- and science-related GPS
information is at:
http://www.colorado.edu/geography/gcraft/notes/gps/gps_f.html
It provides many links to GPS related databases.
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 Russia.
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 SPACEWARN Bulletin No. 545. It will not be repeated in view of the excellent updated source at: http://www.glonass-ianc.rsa.ru/ maintained by the Information-Analytical Center (IAC), Russian Space Agency.
Dr. Richard Langley of the University of New Brunswick, Canada has provided the following GLONASS status on 18 March 2003:

Notes
-----
1. NORAD Catalog Number is also known as U.S. Space Command (USSPACECOM)
object number.
2. The numbers listed first in the "Kosmos Numbers" column are the designators
assigned by the Russian Federation. Where these differ from the
designators assigned by the United States, the latter are given in
parentheses.
3. Channel number, k, indicates L1 and L2 carrier frequencies:
L1 = 1602. + 0.5625 k (MHz)
L2 = 1246. + 0.4375 k (MHz)
4. Status codes:
Res = satellite not in service but held in reserve
OK = satellite fully operational.
UNH = satellite currently flagged unhealthy.
CHK = satellite undergoing checkout and commissioning.
The date listed is the date the satellite was removed from service (Moscow
Time) as reported by the Coordinational Scientific Information Center,
Moscow.
5. All GLONASS satellites employ cesium atomic clocks.
6. The first GLONASS satellite was launched on 12-Oct-82. GLONASS 1 through
79 are no longer in service.
7. GLONASS 40 and 41 were launched with the Etalon 1 laser ranging satellite.
GLONASS 42 and 43 were launched with Etalon 2.
8. The GLONASS numbering scheme used in this table includes the 8 "dummy"
satellites orbited as ballast along with "real" satellites on the first 7
GLONASS launches. The second number in the "GLONASS Numbers" column is
that assigned by the Russian Space Forces.
9. New GLONASS channel allocations were introduced in September 1993 aimed at
reducing interference to radio astronomy. Note the use of the same channel
on pairs of antipodal satellites.
10. The most recent triple GLONASS launch took place on 25-Dec-02 at
07:37:58 UTC (ref. NAGU 086-021226). GLONASS 791 became active on
21-Jan-03 at 07:00 UTC (ref. NAGU 002-030121). GLONASS 792 and 793 became
active on 31-Jan-03 at 00:30 UTC (ref. NAGUs 003-030131 and 004-030131).
All three satellites are regular GLONASS satellites (not GLONASS-M).
11. GLONASS 711, the first GLONASS-M satellite in orbit, has been set unhealthy
since launch. However, its signals, at times, are usable.
12. Number of GLONASS satellites currently in service: 11.
13. Number of GLONASS satellites currently usable: 8.
14. Status of satellites compiled by Richard B. Langley, Dept. of Geodesy and
Geomatics Engineering, University of New Brunswick with the assistance of
Peter Daly, University of Leeds.
