AMSAT News Service Bulletin 001 01 From AMSAT HQ SILVER SPRING, MD January, 1, 2012 To All RADIO AMATEURS BID: $ANS-001 01

A Note About the New AMSAT News Service Format

The ANS news bulletins have traditionally been sent out using a packet header format on each item In the year 2012 we are no longer sure how many VHF-UHF PBBS systems remain active that are re-distributing ANS bulletins via RF-based AX 25 Perhaps the packet header is no longer a requirement for each individual news item

ANS plans to continue to distribute the bulletins in our traditional plain-ascii format so this is not changing Previous inquiries have indicated a very strong preference for the plain-ascii format

In this bulletin you will observe we have preserved the e-mail style of plain ascii text, 70 character lines We preserved packet compatibility by placing a single packet-header at the top of the news and a single /EX at the end of the entire news If this still goes out by packet SB SAT @ AMSAT $ANS-001 01 should still be able to be pro- cessed, received, and read

Happy New Year from the AMSAT News Service crew!

ARISSat-1 altitude is rapidly decreasing

On Tuesday, 27 Dec 2011, ARISSat-1 was losing about 4 1 km (~2 5 miles) a day in altitude, by Friday 30 Dec 2011 the decay was 5 9 km (3 6 miles) per day This rate will continue to increase over the next days and ultimately result in the satellite burning up in the atmosphere Telemetry reports haven't shown a large increase in temperatures yet, please collect and report these values during each illumination period There have been a number of people that continue to update their calculations on when the satellite will re-enter Dates range from 30 Dec to 16 Jan The fall rate dh/dt is increasing dramatically Be sure to do daily updates of the ARISSat-1/RadioSkaf-B Keps from Celestrak com The ARISSat-1 orbit changes daily while the satellite continues to lose altitude Roland, PY4ZBZ from Brazil has updated graphs of height and fall rate on his Web site: http://www qsl net/py4zbz/arissat htm#r

[ANS Thanks Gould, WA4SXM, for the above information ]

Now that ARISSat-1 is in its last days, the Chicken Little Contest web site has been updated to include the individual submissions in each category nearest its likely reentry time

www amsat org/amsat-new/ARISSat/ARISSatContest

You can see how you are doing compared to the competition! It appears that the submissions are sufficiently spread out that we will be able to determine unique winners in each category However, you can help with this by keeping the telemetry submissions coming Space Command does not maintain precise Tracking and Impact Prediction (TIP) for minor spacecraft A small satellite is considered to have reentered when three consecutive tracking stations fail to acquire it, which leaves a considerable window While the formal last telemetry contest is only open to submission through the telemetry programs, keep listening and note the time and place where you hear it last After it has been confirmed to have reentered, the last reception including voice and CW, may help narrow that window unless transmissions cease significantly before reentry

          OSCAR-11 REPORT   29 December 2011

This report covers the period from 01 September to 28 December 2011 The satellite has continued to operate in a very predictable way since the last report, and no changes have been observed During this time the satellite has been heard reliably during its ten-day transmission periods Excellent signals have been reported from stations located around the world, and good copy obtained from decoded telemetry frames

The easiest way to check whether OSCAR-11 is operational is to look at the General Satellite Status website http://oscar dcarr org/index php You can also calculate the operating schedule from the last switch-off time, which was 28 December 2011 at 15:00 UTC (approx), using 10 35 days off followed by 10 35 days on

Reception reports have been received from Gustavo LW2DTZ, Bob KI0G, Rolf HB9TSO and Francesco IT9JRU Many thanks to all and those who posted to the status website

The satellite is currently in eclipse during all evening passes over the UK, resulting in lower signal strengths at these times Owing to the gradual precession of the orbit, the season for eclipses of the evening passes is longer this year compared with the winter last year

The on-board clock continues to gain, 28 seconds during the current reporting period, and 112 seconds since regular transmissions were resumed at the end of August 2010 There is however a large accumulated error of 308 54303 days slow This was caused mainly by the clock stopping during eclipses, when there was also an unknown drain on the power supply The units of the least significant digit correspond approximately to seconds (0 86 seconds actually)

The VHF beacon frequency is 145 826 MHz AFSK FM ASCII Telemetry The satellite is operating in the default mode, with a cycle time of 20 7 days 10 35 days on followed by 10 35 days off

At the present time, while OSCAR-11 is operating in a predictable way, I no longer need direct reports or files by e-mail However, could all listeners continue to enter their reports on the general satellite status website This is a very convenient and easy to use facility, which shows the current status of all the amateur satellites, and is of use to everyone Reports around the expected times of switch-on and switch-off are of special interest, especially for times 12:00 - 18:00 and 22:00 - 07:00 UTC, when the satellite is out-of-range in the UK The URL is http://oscar dcarr org/index php

A longer version of this report report is available on my website, and new listeners to OSCAR-11 should read this for further information The URL is www g3cwv co uk/oscar11 htm This page contains a links to the longer report, a short audio clip to help you identify the satellite and a file of the last telemetry received The website also contains an archive of news & telemetry data which is updated from time to time, and details about using a soundcard or hardware demodulators for data capture There is also software for capturing data, and decoding ASCII telemetry

If you place this bulletin on a terrestrial packet network, please use the bulletin identifier $BID:U2RPT157 CWV, to prevent duplication

Highlights of ARISS International Delegates Annual Meeting

The ARISS International Delegates Annual Meeting was held at the NASA Johnson Space Center in Houston, TX on October 28-29, 2011

The ARISS Team meeting was opened with a welcome by Susan White, lead of Johnson Space Center Education Office The main objective of the NASA Education Office is to promote STEM (science, techno- logy, engineering, and math) activities Susan said NASA greatly appreciates the efforts the ARISS team puts into promoting STEM, and applauds the fine educational outcomes garnered by ARISS She said NASA is focusing heavily on two new things for Fiscal Year 2012 (October 1, 2011 to September 30, 2012):

Continue to make the very best use of its resources, including resource help from outside of NASA -- such as from ARISS
The other focus is professional development promoting the STEM initiative

ARISS Delegates submitted their status report for their region prior to the meeting These have been posted at: http://www amsat org/amsat/ariss/Meetings/2011_Houston/Presentations/

Highlights of the presentations include:

ARISS = Education ARISS will continue with its support of the School Contacts
Summary of the ARISSat-1/KEDR mission
Hardware proposal regarding the installation of a new Kenwood D710 radio in the Columbus module
Hardware proposal for new power supply for ISS-Ham operations in the Columbus module
Ongoing work with ARISS-Europe, AMSAT-Italy, ESA, and Kayser-Italia for implementation of the HAMTV - Digital ATV with S-band downlink from the Columbus Module S-band ATV equipment would be required at schools for use in video ARISS contacts

More details about the meeting along with photographs of the meeting are included in the next AMSAT Journal which will be mailed to all AMSAT members

NO-44 PCSAT Recovery Attempt in Progress

NO-44 PCSAT-1 has remained semi-operational in sunlight since its battery had failed years ago The satellite shuts down due to low power from the solar cells in eclipse On many passes a poor sun angle provides only enough power for it to digipeat only 1 or 2 pack- ets via 145 825 MHz AX 25 A few times a year PCSAT's orbit has it in 24-hour sunlight for a few days One of these full-sun periods is occuring now

Bob Bruninga, WB4APR, control station for the US Naval Academy Sat- ellite Lab, the "owners" of PCSAT, is attempting to recover PCSAT by uplinking commands Due to the poor sun angle on the solar cells just one single packet from a user other than the control station during a pass will easily kill that pass's chance of recovery

Bob says they only get a few packet chances per pass for recovery He needs for the stations with beacons on 145 825 MHz to please turn off your beacon - it competes with the slim power budget that the control station is attempting to utilize

This past week, European control station Mike Rupprecht, DK3WN man- aged to recover PCSAT for a short period before low voltage reset the satellite again

Please do not attempt to digipeat via PCSAT on 145 825 MHz while the satellite recovery effort is underway Bob says it will take the right sun angle, at the right time to ensure success

It is OK for ground stations to access the ARISS packet system on the ISS, also on 145 825 MHz when PCSAT is not in range

FO-29 Recovery and Testing Continues

The FO-29 Command Team reported that their December 23 test operation was successful They were able to gain control of the satellite and copy its telemetry beacon while it was over Japan

FO-29 stopped operating when it entered eclipse An example of the telemetry copied during testing has been posted as a sound file at: http://www ne jp/asahi/m-arai/gkz/sound/FO29-111223142200-142544z mp3

A tentative FO-29 operation schedule for early January, 2012 is:

Jan 1 04:43 UTC Jan 3 04:37 UTC Jan 4 05:28 UTC

The transponder is expected to operate until eclipse Stations in East Asia, Australia/New Zealand and southern South America will be able to attempt to use FO-29

University of Rome UniCubeSat GG Qualified for Vega Maiden Flight

The AMSAT-UK web carried the news that a seventh University Cubesat has passed its Final Acceptance Review at ESA and has been added to the manifest of the maiden Vega Launch

The January 2012 inaugural launch of the ESA Vega rocket from the ESA spaceport at Kourou in the Caribbean will carry the amateur radio microsatellite ALMASat-1 and now CubeSats The orbit is planned for 1450 by 300 km at an inclination of 69 5 degrees

There were slots for up to nine CubeSats on the Vega launch This week it was announced that UniCubeSat GG (Universitï¿½ di Roma ï¿½La Sapienzaï¿½, Italy) will be the seventh cubesat aboard this launch

The UNICubeSat mission goal is the in situ measurement of atmos- pheric density, which is made possible by the low perigee altitude of the VEGA Maiden flight orbit All of the UNICubeSat key compon- ents, such as solar arrays, batteries, communications and on board data handling are developed on the heritage of the four UNISAT satellites, designed, built and launched by the GAUSS team at the Scuola di Ingegneria Aerospaziale in the last decade The SPIV ground station, located in Roma, will be the main ground station for the UNICubeSat mission

The previously announced six cubesats on the maiden Vega Launch included:

Xatcobeo (collaboration of the University of Vigo and INTA, Spain)
Robusta (University of Montpellier 2, France) E-St@r (Politecnico di
Torino, Italy) Goliat (University of Bucharest, Romania) PW-Sat
(Warsaw University of Technology, Poland)
MaSat-1 (Budapest University of Technology & Economics, Hungary)

As well as the CubeSats Vega will also carry the Amateur Radio micro- satellite ALMASat-1
