The Russian Space Agency, Roscosmos announced that a nano satellite with the designation, NS-1 was hand-launched during a space walk that began at 14:00 UTC Monday, August 18, 2014.
The satellite is also referred to as the Peruvian Cubesat Chasqui-1 and weighs 1.5 kg. The satellite’s main mission is to serve as a platform for testing micro-electronics and optical devices used in cubesat applications.

Its secondary mission is to operate as an amateur radio satellite. It’s transmit downlink is 437.025 MHz. The craft will send information in CW mode. It also transmits images stored in memory, photos taken by two on board cameras and will send telemetry. Data transmissions will use either 1200 bps AFSK AX.25 or 9600 bps GMSK modes.

ARISS NEWS RELEASE no. 14-02

Current discussions between the ARISS team and NASA suggest the possibility of voice contacts with the International Space Station (ISS) during Saturday’s ARRL Field Day activities this coming weekend.
In a June 23 email, Kenneth Ransom, the ISS Ham Radio payload developer, stated “I have received a response from astronaut (Reid) Wiseman that he is willing to try and work some stations on Saturday. Pass times begin very soon after the start of Field day.” Wiseman would operate under the call sign, NA1SS. Should Alex Gerst participate, he would use the call sign, DP0ISS.
If voice operation does occur, It will likely take place from the Columbus (COL) module using the standard Region 2 uplink frequency of 144.49 MHz and 145.800 MHz for downlink. It’s expected that the packet system will be operational on 145.825 MHz during periods when the crew is not available.
It’s not clear whether any of the Russian crew would participate from the Russian module, but if so, they would be directed to use 437.550 MHz for any contacts using the call sign RS0ISS. The COL would also be available to their crew using the VHF frequencies above, if Wiseman is not operating.
Listed below are approximate pass times and a chart showing ISS passes for the Field Day weekend. The pass times shown are not definite, scheduled times with the crew. They may or may not be able to support these times. And, updates to this tentative plan will be released as they become available.

In a message to the LituanicaSAT-1 team, AMSAT-NA OSCAR Number Administrator Bill Tynan, W3XO announced, “LituanicaSAT-1 has met all of the requirements for an OSCAR number. My findings from information provided to AMSAT-NA and IARU officials confirm this to be true. Accordingly, under the authority vested in me by the AMSAT-NA President, I do hereby assign LituanicaSAT-1 the designation LituanicaSAT OSCAR-78, or LO-78. I, and all of the amateur radio satellite community, wish LituanicaSAT OSCAR-78 a long and successful mission.”
On behalf of the LituanicaSAT-1 team, Simon Kareiva, LY2EN replied, “It is my honor and pleasure to accept this assignation. Our team is focused to keep LO-78 operational for the benefit of amateur radio as long, as it is possible for a small cubesat. Thank you very much, Simon LY2EN.”
The LituanicaSAT-1 team has announced activation of the FM transponder. A general rule to find out if the transponder is working at the moment is to monitor the beacon frequency on 437.275 MHz. If you can hear CW FM beacon it means that transponder is off, if you cannot hear it – the transponder is on. The transponder frequencies are approximately 435.1755 MHz (+/- 10 kHz Doppler shift) for the downlink and 145.950 MHz for the uplink with 67 Hz CTCSS.
