SB SAT @ AMSAT $ANS-170 01 AMSAT-NA Files Formal Comments on Proposed ITAR Changes

AMSAT News Service Bulletin 170 01

From AMSAT HQ SILVER SPRING, MD June 19, 2011 To All RADIO AMATEURS BID: $ANS-170 01

AMSAT submitted comments to the U S Department of State/Directorate of Defense Trade Controls (DDTC) on June 13, 2011 in response to their proposed rule making on International Traffic in Arms Regulations (ITAR), which would provide clarification on defense services, noting that public domain material is not subject to ITAR

AMSAT asked DDTC to not only acknowledge that public domain materials are not subject to ITAR, but to expand the scope of how they view how materials are to be placed in the public domain AMSAT requested that rather than focus on the method of placement of materials in the public domain (e g printed publication), the critical criteria should be the intent of the originator to broadly and freely make such material available to anyone who has the ability to access it via appropriate means, including electronic origination and distribution

The full copy of AMSAT's comments will be published in an upcoming edition of the AMSAT Journal An electronic copy of AMSAT's comments can be viewed on the AMSAT web at: http://tinyurl com/3jtbff2

SB SAT @ AMSAT $ANS-170 03 It's Time to Get Ready For ARISSat-1

AMSAT News Service Bulletin 170 03

From AMSAT HQ SILVER SPRING, MD June 19, 2011 To All RADIO AMATEURS BID: $ANS-170 03

A few weeks remain before the planned July deployment of ARISSat-1 from the ISS The AMSAT News Service will bring you more details in the coming weeks Here are some reminders to help you get your station ready for ARISSat-1 operation

145 950 MHz FM Downlink:

FM transmissions will cycle between a voice ID as RS01S, select tele- metry values, 24 international greeting messages in 15 languages and SSTV images One of the messages will be a conversation between Yuri Gagarin and ground control See the next news item for pointers to get your station ready to receive the SSTV images

435 MHz - 145 MHz Linear Transponder:

The linear transponder will operate in Mode U/V (70 cm Up, 2m Down) It is an 16 KHz wide inverting passband and the convention will be to TX LSB on the 435 MHz uplink and RX USB on the 145 MHz downlink This mode is designed to work with low power transmitters and omni antenna

145 919 MHz/145 939 MHz CW Beacon:

The CW transmissions will be callsign ID RS01S, select telemetry, and callsigns of people actively involved with the ARISS program

145 920 MHz SSB BPSK-1000 Telemetry:

The BPSK transmissions will feature a new 1kBPSK protocol developed by Phil Karn, KA9Q to be readable in low signal level conditions The BPSK data will transmit satellite telemetry

The ARISSat-1 BPSK-1000 downlink is transmitted in SSB mode on 145 920 MHz When the CW2 beacon on 145 919 MHz is active this indicates that the BPSK-1000 format is being transmitted If the CW1 beacon on 145 939 MHz is active this indicates the backup of BPSK-400 format is being transmitted

Transmitting at 100 mW, both BPSK rates include Forward Error Correction (FEC) and it is expected that modest quarter-wave antennas with low-loss coaxial cable will provide sufficient signal strength for decoding and display by the ARISSatTLM software

An audio feed from an SSB receiver to the computer's soundcard input is needed An initial "Receive Only" configuration is easily done consisting of an audio patch cable between your radio and the soundcard Take the speaker or headphone output from the radio and run it into the line (or mic) input on your PC sound card

BPSK-1000 sounds like a "shusssch" with a higher pitch than the 400 bps growl It is difficult to tune by ear The CW2 beacon is used as a tuning signal for BPSK-1000 The PC and Mac ARISSatTLM software display contains a dotted line that you use to tune your receiver until the CW signal bumps lines up with the dotted line on your PC screen This will allow you to decode the BPSK-1000 signal and you will also be able to copy the CW2 beacon

SB SAT @ AMSAT $ANS-170 04 ARRISat-1 Team Pointers to Get Ready for SSTV Reception

AMSAT News Service Bulletin 170 04

From AMSAT HQ SILVER SPRING, MD June 19, 2011 To All RADIO AMATEURS BID: $ANS-170 04

The ARISSat-1 FM downlink on 145 950 MHz includes live SSTV images as part of the cycling voice ID, select spoken telemetry values, and the international greeting messages Here are some pointers to help you get your station ready to receive and dis- the SSTV pictures transmitted by ARISSat-1

One fun feature is that there are four SSTV cameras mounted on the spacecraft On photos of ARISSat-1 you may have noticed black brackets on the outside of the spacecraft These hold the mirrors that reflect the light onto the lens of the cameras The software- defined-transponder will use the image data from the cameras to generate the SSTV downlink

ARISSat's software will sequentially select a new or stored image from one the four cameras There are two pre-recorded images as part of the sequence The camera that took the the picture can be identified by the color of the call sign in the upper left of the SSTV image The SSTV image will be sent down as FM audio SSTV in Robot 36 format on 145 950 MHz about every 140 seconds

The RF downlink power on the 145 950 MHz FM downlink will be 250mW which is predicted to provide a link margin around 6 dB on an HT with a 'big whip' when the satellite is at 15 degrees elevation This should be sufficient to receive SSTV pictures although you may need to orient the whip to line up the antenna polarization

ARISSat-1 is not stabilized so the antenna orientation is unpredict- able and a certain amount of fading will happen The receiving link margin may be improved with a handheld beam such as an "Arrow", "Elk", or "Cheap Yagi" antenna (See: http://www wa5vjb com/references/Cheap%20Antennas-LEOs pdf)

General Overview Radio-to-Soundcard Interface

To view the SSTV downlink from ARISSat-1 you'll need a computer running SSTV software for your soundcard and an audio connection between your radio and the computer

If you are already on the air with other amateur radio soundcard applications chances are you are ready to receive ARISSat's SSTV downlink with little or no modification to your setup

The audio from the radio to the computer is the key link An initial "Receive Only" configuration is easily done consisting of an audio patch cable between your radio and the soundcard Take the speaker or headphone output from the radio and run it into the line (or mic) input on your PC sound card

Setting the level is simple also as the MMSSTV software has a bar indicator Just adjust the sound card gain slider and/or radio volume control so that the SSTV signal is within the center part of the bar MMSSTV will give you an "overflow" indication if the volume is too high

If your rig has a 'Line Out' connection this can be run to the soundcard 'Line In' Using the radio 'Line Out' you won't have to deal with the interaction of the radio's volume control with the soundcard levels But you will still need to use the soundcard
'Volume Control' to set the 'Line In' levels

SSTV Software Download Sites

There are many amateur radio SSTV software decoding applications available One of the easiest to use on Windows computers is the MMSSTV program This can be downloaded from: http://mmhamsoft amateur-radio ca/pages/mmsstv php

The Ham Radio Deluxe software package also includes SSTV operation

SSTV software for the Mac is available at: http://web me com/kd6cji/MacSSTV/MultiScan html

SB SAT @ AMSAT $ANS-170 09 Follow Up to Receiving STEREO-B at 219 Million KM

AMSAT News Service Bulletin 170 09

From AMSAT HQ SILVER SPRING, MD June 19, 2011 To All RADIO AMATEURS BID: $ANS-170 09

James Miller, G3RUH sent an interesting follow up to the ANS news of AMSAT-DL success in receiving the 8 GHz downlink from the solar observation STEREO-B satellite A FUNcube dongle and downconverter were used in the the demonstration documented in the videos on the Southgate ARC site (See: http://tinyurl com/6eukmjv - "AMSAT-DL break FUNcube Dongle distance record)

James wrote, "Actually, the Stereo-A and Stereo-B spacecraft are received (more conventionally) every day, and the data automatically forwarded to NASA The Bochum Dish, operated by AMSAT-DL is one of four "Partner Stations" downloading the low speed Beacon telemetry for NASA/NOAA The others are DL0SHF at Kiel, CNES in Toulouse, France, and NICT at Koganei, Japan And one more station is urgently needed, especially from North America "

There is a comprehensive article about this work at: http://www amsat org/amsat/articles/g3ruh/127 html

Data is transmitted from STEREO in one of two modes; (a) high speed (currently 720 kbps), stored data (up to 1 Gb), intended for the Deep Space Network (DSN) to collect the high resolution science data some 8 hours/day, and (b) a low speed 633 bps continuous real time subset of the solar data intended for collection by smaller ground stations

AMSAT collects low speed data The ground stations then forward the data via the Internet to NASA GSFC for processing where it is posted on the web in near real time for all to use, including the various world wide organizations monitoring and predicting Space Weather The ground network for the low speed data is organized and coordin- ated by the SWPC in Boulder, Colorado

The spacecraft transmit 63 watts to a 1 1m dish at 8 4 GHz RHCP, an e i r p of approximately 85 dBm
