LituanicaSAT-1 Camera and FM Voice Transponder

The LituanicaSAT-1 (LO-78) team have announced activation of the FM transponder.

Dear radio amateurs,

I want to notify that finally after a long break (mainly due to ground station maintenance works) we have switched the transponder on again. Duty cycle will depend on battery voltage level. All other telemetry is inactive to save power. We hope the signal should be even better now as the satellite is descending steadily to 300 km and wish you all good QSOs! Next update in 24 hours.

LituanicaSAT-1 will in the coming weeks re-enter into the Earth atmosphere and burn up, this may occur by August 5. Note: It is understood that JSpOC mixed up the IDs of the satellites that were launched from the ISS on February 28 giving rise to a misleading date for re-entry of LituanicaSAT-1. It is ARDUSAT 2, which was deployed with LituanicaSAT-1 that is expected to decay on July 2.

Frequency are approximately 435.1755 MHz (+/- 10 kHz Doppler shift) for the downlink and 145.950 MHz for the uplink with 67 Hz CTCSS.

The tiny satellite is just 10x10x10 cm with a mass of 1.090 kg yet it has a VGA camera and a 145/435 MHz FM voice transponder, designed and built by Lithuanian radio amateurs.

The prototype of the FM repeater has been operating in the home of its designer Žilvinas Batisa LY3H in Elektrėnai, Lithuania. Further information at http://ly3h.epalete.com/?p=303

LituanicaSAT-1 was built by students from Vilnius University and deployed from the International Space Station (ISS) on February 28, 2014.

There will be a presentation on LituanicaSAT-1 by Gintautas Sulskus at 12pm BST on Saturday, July 26 at the AMSAT-UK International Space Colloquium which takes place at the Holiday Inn, Guildford, GU2 7XZ. The event is open to all, admittance £10 per day, further details at https://amsat-uk.org/colloquium/colloquium-2014/

LituanicaSAT-1 Camera and FM Voice Transponder

AMSAT-NA has announced that the amateur radio satellite LituanicaSAT-1 has been awarded the designation OSCAR-78, or LO-78.

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 voice 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 the CW FM beacon it means that the 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.

The LituanicaSAT-1 team have announced activation of the FM transponder.

Dear radio amateurs,

The LituanicaSAT-1 transponder is currently on and should remain so. General rule to find out if the transponder is working at the moment is following: if you can hear CW FM beacon on 437.275 MHz it means that transponder is off, if you cannot hear it – transponder is on.

LituanicaSAT-1 Camera and FM Voice Transponder

The LituanicaSAT-1 team have announced the FM transponder should be active until June 4, 2014.

Dear radio amateurs,

Due to favorable orbit conditions LituanicaSAT-1 is now operating under 100% sunlight until about 4th of June. Thus we have decided to turn the transponder on during this period. The CW fm beacon and packet telemetry are also on right now.

LituanicaSAT-1 Camera and FM Voice Transponder

The LituanicaSAT-1 team ask for your support in tracking the satellite and reporting telemetry.

Dear radio amateurs,

For some unknown reason the satellite has rebooted several times during long term transponder test and due to that the transponder has been shut down automatically. Satellite is operating currently on high energy consumption mode as the attempt to reconfigure modes during the pass over our ground station today was unsuccessful. We therefore would like to ask for your support in tracking the satellite and reporting telemetry. If battery voltage drops below 7.2 V, the satellite will enter safe power mode and as a result you should only hear the CW FM beacon on 437.275 MHz and no packets.

Thank You in advance for your support.
