MONDAY JANUARY 5, 1998
SpaceNews originates at KD2BD in Wall Township, New Jersey, USA. It
is published every week and is made available for non-commercial use.
* SPUTNIK-40 NEWS *
===================
Reports received from across the globe confirm that the Sputnik-40/RS-17
satellite has gone silent. Sputnik-40 was released from the Mir space
station on 03-Nov-97, and was operational up until the end of 1997.
The satellite remained operational for a period of time that exceeded
all expectations. Reception of its beacon transmitter was confirmed
by ground stations worldwide using even very modest receiving equipment.
* AO-16 S-BAND NEWS *
=====================
Jim White, WD0E, recently reported that AMSAT-OSCAR-16's S-Band beacon
transmitter has been turned off. Several weeks ago spacecraft controllers
had it on for some testing and confirmed that the satellite does not have
the power budget to keep the S-Band beacon and the 70 cm transmitter on
at a power level that supports entry level ground station operations.
The 437.05 MHz 70-cm transmitter has to be run at about 0.5 watts to
allow the S-Band transmitter to remain on. Any higher than that and
the spacecraft software turns the S-Band transmitter off to maintain
a safe battery voltage.
Ground stations interested in testing S-band receive equipment can use
either the DOVE-OSCAR-17 S-Band transmitter on 2401.220 MHz or the
UoSAT-OSCAR-11 S-Band transmitter.
* MIR NEWS *
============
The Orbital Report On-Line reports that a TsSKB-Progress Soyuz U vehicle
was launched from Baykonur, Kazakhstan, on 20-Dec-97, to loft the Progress
M37 cargo spacecraft to the Mir space station. The 7,195-kg spacecraft,
carrying 2,500 kg of supplies, docked with the station on 22-Dec-97.
The 72-kg Inspektor sub-satellite failed shortly after deployment from the
Progress M36 cargo spacecraft leaving the Mir space station on 17-Dec-97.
The US $15-million spacecraft built by Daimler-Benz Aerospace (DASA) of
Bremen, Germany, was intended to maneuver around the station for a 30-hour
external inspection mission. Unfortunately, due to a faulty attitude
sensor, the Inspektor pointed its camera in the wrong direction and
could not image the station.
Miles Mann, WF1F, reports that Mir's 2-meter amateur radio station was
temporarily moved from the core module and installed in the Priroda module.
This move was performed to take advantage of the backup triband antenna
shared with the SAFEX II 70-cm FM repeater installed on Mir. Although a
new packet radio TNC was installed on Mir several weeks ago, not all the
TNC parameters have been properly configured. MIREX has asked that ground
stations monitoring the Mir Personal Message System (PMS) to please be
patient while the necessary adjustments are made.
The SAFEX repeater has been active on an intermittent basis. Last week,
the crew turned off the PL tone feature of the repeater, thereby making
it easier for weak stations to access the repeater. This change also makes
the repeater to transmit static for long periods of time followed by short
time-outs. Users are asked to compensate for Doppler Shift for EACH
transmission. The following chart may be used as a guide:
Downlink Uplink split
