Piraja PS8RF. 

"Amigos,

Recebi um telefonema do Sr. Sergio Almeida, do INPE, solicitando nossa ajuda como radoamadores.
Ele, por sua vez, foi solicitado por colega da NASA para que esta envolvido no lançamento de um nanosatélite para radioamadores (dados em e-mail abaixo).
Precisam de radioamadores brasileiros que acompanhem/monitorem o lançamento.

Está bastante em cima da hora, porque o lançamento será hoje, por volta do entardecer O e-mail do Sr. Rogan, pesquisador da NASA é

rogan.s.shimmin  nasa.gov

e a página do projeto é www.phonesat.org

Peço a vocês (estou enviando este e-mail aos colegas de que tenho conhecimento do interesse de operação via satélite)  que divulguem rapidamente essa mensagem aos colegas que tem condições de operação para acompanhar o lançamento e para que se empenhem em prestar essa ajuda. 

Se precisarem mais dados podem enviar e-mail diretamente ao Sr. Rogan (NASA) ou entrar em contato com o Sr. Sergio, no INPE   jsergio  lit.inpe.br   Fone: (012) 3208-6292/6290

Prezado Orlando,

Acabamos de falar ao telefone.
Tivemos aqui no INPE uma solicitação de um colega da NASA Ames (Rogan Shimmin) buscando suporte do pessoal de Rádio Amador para efetuar tracking do lançamento de um nanosatélite deles.
Abaixo está a mensagem dele, contendo o e-mail dele e um link para a página do lançamento.
Sei que está muito em cima da hora, mas agradeceria bastante uma tentativa sua de ajuda para este caso.
Desde já agradeço bastante sua atenção e tempo gasto com isso.

Abraços,

Radio settings

    Call sign: KJ6KRW
    Frequency: 437.425 MHz
    Modulation: AX-25 AFSK
    Data Rate: 1200 bps

PhoneSat Packet description

PhoneSat satellites are emitting packets over the amateur radio band at 437.425 MHz. All three satellites transmit using AFSK (1200 bps) modulation, AX.25 packet coding and have vertical linear polarization.

The two PhoneSat 1.0 satellites, Graham and Bell, transmit with a periodicity of respectively 28 seconds and 30 seconds. The PhoneSat 2.0 beta satellite, Alexander, transmit with a periodicity of 25 seconds.

The following is a detailed description of the packets that you will be receiving.
PhoneSat 1.0

Three different types of packets ASCII85 encoded. We are encoding bits instead of ASCII characters. Therefore, if you want to decode the packet, normal online ASCII85 decoders will not work. Use PhoneSat's Decoder to decode your packets.
Health Data Packet

After being decoded, the packets will contain the following data:

    ID: 1byte, identifier of which satellite you have received from.
    Restarts: number of restarts of the PhoneSat App.
    Reboots: number of reboots of the phone.
    Counter: number of packets sent since the beginning of the mission.
    Phase1: number of packets sent during phase 1 (only health data).
    Phase2: number of packets sent during phase 2 (health data and picture packets).
    Time: unix time in seconds.
    Voltage: battery Voltage in Volts.
    Temp1: exterior temperature in Kelvin.
    Temp2: interior temperature in Kelvin.
    Accel: accelerometer value for X, Y, Z axes from the phone sensor in m/sec2.
    Compass: magnetic field value for X, Y, Z axes from the phone sensor in nanoTesla.
    Text: "hello from the avcs".

Anyway, the satellite I'm working on will be launched later this week from Wallops Island, VA. It's a nanosat that will be transmitting on the amateur radio band. We're looking for radio operators around the world to track it - is there an amateur radio club at INPE? If so, could you please refer them to our website phonesat.org. I'd be delighted to help if they have any questions J

All the best,

Rogan"
