Mir to Launch New Mini-Sputnik

AMSAT-France tells ANS they have delivered a new model of mini-Sputnik satellite to the Mir space station. Tentatively, this version will be hand launched during a space walk scheduled for November 11, 1998. The announcement of this new 'bird' comes almost one year to the day after the launch of Sputnik 40/RS-17, which commemorated the launch of the first artificial Earth satellite by the USSR in 1957.

Called Sputnik 41 (and possibly RS-18), this new satellite is the same size as its predecessor, about 8 inches in diameter. At almost 9 pounds, this latest version will carry a 150-200 mW transmitter that will transmit on 145.812 MHz (plus/minus 5 kHz and Doppler shift). The new satellite does not have any solar cells; the expected operational lifetime is about 30 days.

AMSAT-France is cooperating with the educational department of the Russian Aeronautic Federation to bring about this latest Sputnik encore. Gerard, F6FAO, tells ANS that Sputnik 41 is completely new and not the spare model of Sputnik 40 that is still on board Mir. F6FAO hopes there will be an opportunity to have this spare model launched sometime in 1999.

Gerard tells ANS that in addition to the 'bip-bip' beacon plus audio-frequency telemetry (indicating internal temperature), Sputnik 41 will also broadcast pre-recorded voice greetings in three languages: French, English, and Russian. One message, read by 14-year-old Constantin Sambourov, declares in Russian-accented English: "1998 was the International Year of Air and Space." Sambourov is the son of Sergei Sambourov, RV3DR, who manages Amateur Radio activity aboard the Mir station. Another English message read by Project Chief Victor Kourilov of the Russian Aeronautic Federation, states "International Space School Sputnik Program."

The French and Russian messages convey the same greetings.

A QSL manager for this newest Sputnik has yet-to-be determined.

Stay tuned to ANS for further developments.

SEDSAT-1 Efforts Continue

Efforts to uplink to SEDSAT-1, following a successful launch and insertion into orbit, is continuing with little success reported. The satellite apparently has developed a major power drain problem, indicating that two primary systems, solar panels and batteries, are apparently not performing to specifications. SEDSAT-1 has experienced several negative power cycles during its short time in orbit.

Chris Lewicki, KC7NYV, Program Manager for the University of Arizona Student Satellite Project and a member of the SEDSAT team, tells ANS that several stations are attempting to uplink to SEDSAT-1. Ground stations involved in uplink attempts include P3D Integration Lab members Stan Wood, WA4NFY and Lou McFadin, W5DID, also attempting to uplink is Jim White, WD0E, and Tim Cunningham, N8DEU. SEDSAT Team member Dennis Wingo, KD4ETA, is also working with the P3D Lab.

The primary objective is to establish an uplink to the satellite and then upload a new code necessary to allow changes in the flight parameters. Once the new code is uploaded, "we will basically put the satellite into a more aggressive power conservation mode," said KC7NYV. As it stands now the satellite has been cycling through 25-hour periods of broadcasting telemetry, followed by 13-hour periods of silence, when the spacecraft is attempting to recharge its batteries.

Many stations around the globe have been sending telemetry reception reports to the SEDSAT Team. VK5AKJ, ZL1BIV, CT1EAT, N8DEU and CX6DD have all been e-mailing information that has been very useful. The SEDSAT Team welcomes any reception information regarding the satellite. Reports should be send to:

telemetry@seds.org

Stay tuned to ANS for further developments concerning the status of SEDSAT-1.

PANSAT Status

PANSAT, the Petite Amateur Navy Satellite recently launched from the space shuttle Discovery, is apparently alive and well as it continues to orbit the Earth. The 150-pound Amateur Radio satellite carries a spread-spectrum communication package fabricated by student officers and faculty members at the Naval Postgraduate School.

Dan Sakoda, KD6DRA, PANSAT Project Manager, tells ANS that while naval officers had a major role in the development of the spacecraft, the actual users of the small satellite will be Amateur Radio operators. "The Amateur Radio community and the US military have a longstanding, cooperative relationship. In this case, the Naval Postgraduate School is using ham radio as an aspect in a purely educational endeavor. In return, the radio community has a new resource to investigate spread-spectrum -- a new modulation scheme," said KD6DRA.

Dan recommends 'The ARRL Spread Spectrum Sourcebook' as a good place to start in understanding the spread-spectrum scheme. "Regardless of the perceptions and feelings of those on either side of the spread-spectrum fence, PANSAT will provide a quantitative means of investigating the effects of direct sequence spread-spectrum communications in the 70-cm Amateur band," said KD6DRA.

This new 'bird' is unique in several ways. Satellite operators will connect to PANSAT's bulletin board system using a 9842-baud, simplex, direct sequence spread-spectrum mode. Also, unlike other amateur satellites, PANSAT does not have a beacon mode and the operating system is complex in that the same frequency is used for both uplink and downlink transmissions.

After one week in orbit, ground stations recently made the first contact with PANSAT and downloaded preliminary data. Like other packet radio satellites, PANSAT will require additional software to be uploaded, including operating systems, AX.25 parameters and file transfer protocols. "In addition, we want to see how the spacecraft is operating on its own," Dan said.

The PANSAT Team does not expect the satellite to be available to the Amateur Radio community for another few months.

Discovery Completes Mission -- ISS Next

The Space Shuttle Discovery completed a nine-day scientific research mission, including the return of John Glenn to space, 36 years after he became the first American to orbit the Earth.

Discovery's astronauts glided to a smooth landing at the Kennedy Space Center as Commander Curt Brown and Pilot Steve Lindsey set Discovery down on the 3-mile long landing strip at KSC. The missing drag chute compartment door, which popped off during liftoff, posed no problem for the astronauts and had no effect on the landing. Although not a SAREX mission, the flight was followed by many Amateur Radio operators the world over.

Construction of the International Space Station will now dominate the shuttle schedule, especially the next several flights. NASA will shortly launch the initial effort to build the new space station, following an unmanned Russian rocket that will carry the Zarya cargo module into orbit. The Russian launch, from the Baikonur Cosmodrome in the former Soviet republic of Kazakhstan, is scheduled for November 20th. The Zarya module will be the first component of ISS, an enormous effort that involves the United States, Japan, Russia, Canada, and 12 European nations.

ISS construction activities begin with a shuttle crew launch from the Kennedy Space Center on December 3rd.

Frank Bauer, KA3HDO, AMSAT-NA Vice President of Human Spaceflight Programs, tells ANS "we are proceeding full speed ahead on Amateur Radio aboard the International Space Station." The final flight qualification of the ARISS interim station is expected to be completed in December. According to KA3HDO, this station will allow the crew to operate on voice, packet and digital voice beacons at the beginning of station habitation. The hardware is scheduled to be flown on the STS-96 mission in May 1999. Antennas will be flown and installed shortly thereafter.

ISS crew habitation is planned for late 1999 or early 2000.

SAREX flights will resume with schools in Indiana, Rhode Island, Texas, and Virginia on the schedule to make Amateur Radio contact with the astronauts aboard the space shuttle Columbia in early 1999. The flight, mission STS-93, is tentatively set for a January 21st launch from KSC.

Hams scheduled to fly aboard STS-93 will be Commander Eileen Collins, KD5EDS, Michel Tognini, KD5EJZ and Catherine Coleman, KC5ZTH.

AO-27

Uplink 145.850 MHz FM
Downlink: 436.792 MHz FM
Operational.

AO-27 TEPR States are currently:
4 = 36 = 18 Minutes
5 = 72 = 36 Minutes

This means AO-27's transmitter turns on 18 minutes after entering the Sun and stays on for 18 minutes. AO-27's transmitter is turned off at all other times during the orbit. N4USI reminds stations that this happens on every orbit, approximately 14.2 times a day. The current TEPR settings will cause the satellite to be on during the daytime at northern latitudes.

Kazu, JJ1WTK, tells ANS that the FO-29 Command Team has released the following announcement concerning FO-29 status:

The present JA mode of operation will continue to investigate the frequency of bit errors in the on-board-computer. Reports from Amateurs on the value of channel 2A are appreciated. The position of 2A is the fifth item after 'HI HI' in CW telemetry. The normal value is '00'. Reports should be sent to lab@jarl.or.jp.

FO-29 is still in 'full sun illumination', this should end in December.

The on-board-computer (OBC) did accept commands from ground control before full illumination began. The FO-29 Command Team says digital (JD) mode operation may be available in December. Digi-talker operation is also being planned. The next announcement is expected November 20th.

Uplink 145.850, 145.900 MHz FM
Downlink 435.175 MHz FM, 9600 Baud FSK
Semi-operational.

The satellite has a strong carrier but no downlinked data. ANS has no official information on the cause of this problem.

Richard, G3RWL, reports KO-23 has entered another period of permanent sunlight causing the spacecraft temperature to rise. The higher temperature brings deviation increases and ground stations experience degraded reception (strong carrier but little or no data received). CX6DD and WS4Z also report degraded reception.
