SPX-510 25 April 1996 ************CAUTION! THIS IS A DRAFT, NOT A FINAL VERSION******** SPACEWARN BULLETIN 510 A publication of NASA NSSDC/WDC-A-R&S as the WWAS for IUWDS/COSPAR (All information in this publication was received between 25 March 1996 and 24 April 1996.) A. List of New International Designations and Launch Dates (UT). (USSPACECOM Catalog numbers are in parentheses.) 1996-023A (23848) PRIRODA 23 Apr 1996-022A (23846) MSAT 1 20 Apr 1996-021A (23842) ASTRA 1F 08 Apr 1996-020A (23839) INMARSAT 3-F1 03 Apr 1996-019A (23833) USA 117 28 Mar B. Text of Launch Announcements. 1996-023A PRIODA is the last of the scheduled five Russian modules of MIR and was launched from Baykonur by a Proton-K rocket at 11:48 UT, to dock after three days rather than the usual nine days. The launch itself was three days earlier than the planned data in order to facilitate an American microgravity program; the 19,000 kg module carried 900 kg of American equipments to be delivered to the American astronaut on MIR. Other cargo on board included several remote-sensing Russian instruments. It is likely PRIRODA may later be attached to the planned international space station, Alpha when MIR mission would in 1998. Initial orbital parameters were period 89.9 min, apogee 454 km, perigee 338 km, and inclination 51.65 deg. 1996-022A MSAT 1 is a Canadian geostationary mobile phone communications spacecraft that was launched by an Ariane 42P rocket from Kourou, French Guiana to serve the North American continent. The spacecraft and its transponders are very similar to those of the American AMSC 1. 1996-021A ASTRA 1F is a European (SES, Luxembourg) geosynchronous communications spacecraft that was launched by a Proton-K rocket from Baykonur cosmodrome at 23:09 UT. The 3,010 kg spacecraft is to be parked over 19.2 deg E-longitude to provide direct broadcast TV to Europe through its 16 Ku-band transponders. 1996-020A INMARSAT 3-F1 is a geosynchronous communications spacecraft of the 79 nation consortium and was launched by an Atlas 2A rocket from Cape Canaveral Air Station. The 2,068 kg spacecraft will provide phone links to airlines and passengers through its five L-band beams after parking at 64 deg E-longitude. 1996-019A USA 117 is the latest addition to the Navstar/GPS series of navigational spacecraft. The GPS series is listed in section C-2. Initial orbital parameters were period 718 min, apogee 20,282 km, perigee 20,078 km, and inclination 54.7 deg. C. Spacecraft Particularly Suited for International Participation. 1. 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; an asterisk [*] indicates updated/new information since the last issue. Updates or corrections to the list are possible only with information from the user community.) THE LIST REMAINS THE SAME AS IN SPX-504, BUT WITH ADDITIONS LISTED IN SPX-507. THE SECTION WILL BE REVIVED FROM TIME TO TIME WHEN A SIGNIFICANT VOLUME OF UPDATES WOULD BE AVAILABLE FROM THE USER COMMUNITY. 2. Global Positioning System satellites useful for navigational purposes and geodetic studies. ("NNN" denotes no national name. SPACEWARN Bulletin appreciates suggestions to update this list. An asterisk [*] denotes changes in this issue. SPACEWARN thanks Prof. Richard B. Langley, Univ. of New Burnswick for the updates to this issue.) 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).

Russian Global Navigational (Positioning) Spacecraft, GLONASS constellation. (SPACEWARN requests updates/additions from readers to this list. Entries marked "*" are updates or additions to the list.) All GLONASS spacecraft are in the general COSMOS series. The COSMOS numbers (nnnn) 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) are L1 = 1602.0 + 0.5625K, and L2 = 1246.0 + 0.4375K.

Miscellaneous Items. (This section contains information/data that are entered on occasion and may not be repeated in each issue of the SPACEWARN Bulletin.) NSSDC/WDC-A-R&S is an archival center for science data from many spacecraft. Some data are on line for electronic access. Please contact the Request Office, NSSDC, Code 633, NASA/GSFC, Greenbelt, Maryland 20771, U.S.A., for specific information (REQUEST@NSSDCA.GSFC.NASA.GOV). Information on the current status of the instruments on board from the investigators will be most welcomed.....Precomputed trajectory files and orbital parameters of many magnetospheric and heliospheric science-payload spacecraft may be FTP'ed from NSSDC's ANON_DIR:[000000.ACTIVE] and its several subdirectories. (See the last page of the bulletin for the access method; a file in the ACTIVE directory named AAREADME.DOC outlines the contents.) It can also be accessed through WWW URL: http://sscop1.gsfc.nasa.gov/ssc.html This html also enables executing several codes related to the orbits of many geocentric science payload spacecraft. The codes related to the heliospheric spacecraft trajectories can be executed through URL: http://nssdc/space/helios/heli.html SPACEWARN Bulletin ------------------ The Bulletin is intended to serve as an international communication medium for the rapid distribution of information on satellites and space probes. The material it contains is based on guidelines in the COSPAR Guide to Rocket and Satellite Information and Data Exchange, COSPAR Transactions #8, December 1972, and various Committee on Space Research (COSPAR) resolutions. Hard copy recipients and electronic accessers are encouraged to disseminate the bulletin to interested individuals and institutions in their regions or countries. All bulletins beginning with January 1991 (SPX-447) are now available on line; the SPX number increases by one for each succeeding month (for example, the January 1993 bulletin is SPX-471).

Users are urged to submit their comments and suggestions for the improvement of this bulletin to SPACEWARN Bulletin, World Data Center-A for Rockets and Satellites, Code 633, Goddard Space Flight Center, Greenbelt, Maryland 20771 U.S.A. Categories of Spacecraft To improve the effectiveness of international distribution of satellite and space probe information via the SPACEWARN system, spacecraft are identified in categories according to the urgency and detail of information needed by the scientific community as follows: CATEGORY 1: Spacecraft that carry essentially continuous telemetry or radio beacons, usually on frequencies less than 150 MHz. CATEGORY 2: GPS constellation of positioning/navigational spacecraft. CATEGORY 3: GLONASS constellation of positioning/navigational spacecraft. CATEGORY 4: Occassionally, a list of bright, orbiting objects of visual magnitude 4 or brighter. The bulletin also carries launch dates, international ID's and USSPACECOM catalog numbers, followed by a brief outline of the payload and orbital parameters, re-entry of major objects, and miscellaneous sections. These data are based on launch announcements or on information received from individuals, launching authorities, FBIS and USSPACECOM telexes, and news magazines.
