Bulgarian CubeSat EnduroSat on ISS awaiting deployment

EnduroSat One

EnduroSat One

Bulgaria’s first CubeSat, EnduroSat One, was launched to the International Space Station on the cargo resupply OA-9 mission on May 21, 2018 from the Mid-Atlantic Regional Spaceport in Virginia, USA. On May 24 the Cygnus capsule docked to the Station and the satellite was taken onboard the ISS.

The satellite will be deployed from the ISS in the coming weeks.

The mission aims to popularize the Radio Amateur activities in Bulgaria and it will include cooperation with Bulgarian Federation of Radio Amateurs (BFRA), including workshops and additional educational activities.

The spacecraft has been completely built in Bulgaria. This first educational mission aims to inspire young Bulgarians and give them the chance to participate in a real space program!

The Space Challenges and EnduroSat teams have invested considerable resources, time and effort in preparing the Bulgarian CubeSat. In order to support the Radio Amateur community, the satellite emits in frequencies which are readily available for receiving by anyone with basic communication skills and radio equipment.

It is hoped the mission will help more young Bulgarians learn the basics of satellite communications through practical exercises empowered by the orbiting satellite.

Radio amateurs from around the Globe will be able to listen to the satellite beacon and to receive telemetry data from the satellite on a regular basis. They will be able to connect to the satellite, receive detailed telemetry information and receive a confirmation from the satellite for every established connection which will serve as QSL card.

Beacon: 437.050 MHz CW and 9600 bps GMSK AX.25

End of mission for PicSat

Artist’s impression of PicSat in space

PicSat, launched January 12, carried an amateur radio FM transponder. Unfortunately following a loss of communications in March the team has had to announce the end of the mission.

On the afternoon of Tuesday, March 20, 2018 PicSat suddenly fell silent, after two successful morning passes over Europe. Attempts to re-establish contact have failed, nothing has been heard from the satellite, no sign of life.

There was a short-lived hope that PicSat was heard on Friday, March 30 by radio amateurs at the Morehead State University, but the faint signal heard turned out to be another satellite TIGRISAT.

On Thursday, April 5, 2018, the team decided to call mission-closed. A “pot” (French for party / drink) was organised at noon at the Paris Observatory in Meudon. Sylvestre Lacour gave a short speech. Four radio amateurs who have been PicSat fans and great supporters joined in via a dedicated Google Hangout.

The team will continue to try to understand what went awry, while plans for new projects are being made. PicSat was operational for over 10 weeks. From a technological point of view it has been a success for the LESIA laboratory of the Paris Observatory – PSL, for whom PicSat has been the very first nano-satellite complete built and operated in-house. This experience will open doors for new nano-satellite projects in the (near) future.

Watch Bye Bye PicSat (for now)

Athenoxat-1 QSL Card Challenge

Athenoxat-1 CubeSat 2015


The Athenoxat-1 project team has implemented an interesting experiment (puzzle) where frames containing fragments of images of QSL cards are periodically transmitted by the satellite. Amateurs can participate in the experiment by receiving the fragments and sending KISS files via email to the Athenoxsat-1 project team. The frames will then be processed and the results will posted in their web site with acknowledgements to the participating stations.

AMSAT-BR would like to encourage amateurs to participate. Due to the satellite orbit inclination (15 degrees), only locations with latitudes below the tropics will be able to receive signals from the satellite. Signals can be demodulated using UZ7HO’s high speed soundmodem software (using the GOMX-1 4800 bps demodulator).

Original message from Yesie 9V1SQ describing the experiment follows:

Dear everyone,

Finally we’ve done with the preparation and in-orbit test of beacon puzzle round 2 (data type 3).
We can now inform you that Athenoxat-1 is beaconing data type 3 with 10 frames per burst every minute (30sec interval alternating with Morse CW).

For the stations around our control station (in Singapore), please keep tuning in as the satellite is still beaconing the data type 3 although it may seem appear busy in comm.operation.
The only apparent change is that you may not hear the Morse CW once our comm.operation starts.

We’ve updated our website here: http://www.micro-space.org/ham.html

We actually have started enabling this round 2 yesterday as part of in-orbit test to ensure the system is stable, before we can announce this officially.
At the same time, there are already kss files submissions, we’ll take them into account later.

Please let us know if you need any clarifications.
The kss files can be submitted through the usual address athenoxat@micro-space.org
Please feel free to inform others who may be interested and able to listen to Athenoxat-1.

Thank you in advance for listening.

HuskySat-1 145/435 MHz Linear Transponder CubeSat also has 24 GHz Downlink



A 3U Cube Satellite, dubbed the HuskySat-1, is being developed by an interdisciplinary team at the University of Washington and will be launched into Low Earth Orbit to become the first amateur satellite from Washington state.

HuskySat-1 CubeSat

HuskySat-1 CubeSat

This CubeSat will demonstrate the capabilities of new technologies being developed at the University of Washington and expand the capabilities of CubeSats as a whole. In particular, a high-thrust pulsed plasma thruster (PPT), and high-gain communications system will form the core technology suite on board the satellite.

The majority of the HuskySat-1 is being developed at the University of Washington. The satellite is broken up into different subsystems. Each component is designed to be modular so that they can be most easily developed independently from each other and reused for future missions.

The Pulsed Plasma thruster will use tungsten electrodes and a sulfur propellant.

HuskySat-1 will carry a 30 kHz wide 145 to 435 MHz linear transponder for amateur radio SSB/CW communications along with 1k2 BPSK telemetry. The satellite will also transmit BPSK telemetry at 1 Mbps in the 24 GHz band.

The launch is planned for late 2018 with the ELaNA XXIV mission into a high inclination Low Earth Orbit (LEO).

FM transponder satellite AO-92 open for amateur radio use

AO-92 / Fox-1D CubeSat

AO-92 / Fox-1D CubeSat

On the 03:25 UTC pass on January 26, 2018, AMSAT Vice President Engineering Jerry Buxton, N0JY, announced that AO-92 had been commissioned and formally turned the satellite over to AMSAT Operations. AMSAT Vice President – Operations Drew Glasbrenner, KO4MA, then declared that AO-92 was now open for amateur use.

Initially, the U/v FM transponder will be open continuously for a period of one week. After the first week, operations will be scheduled between the U/v FM transponder, L-Band Downshifter, Virginia Tech Camera, and the University of Iowa’s High Energy Radiation CubeSat Instrument (HERCI).

Schedule updates will appear in the AMSAT News Service Weekly Bulletins and will also be posted to the AMSAT-BB, AMSAT’s Twitter account (@AMSAT), the AMSAT North America Facebook group, and the AMSAT website at https://www.amsat.org/satellite-schedules/

AO-92 was launched on the PSLV-C40 mission from Satish Dhawan Space Centre in Sriharikota, India on January 12, 2018. For the past two weeks, the AMSAT Engineering and Operations teams have been testing the various modes and experiments on board. Testing has shown that both the U/v FM transponder and L-Band Downshifter work very well. The Virginia Tech camera has returned stunning photos and data from HERCI has been successfully downlinked.

AMSAT thanks the 178 stations worldwide that have used FoxTelem to collect telemetry and experiment data from AO-92 during the commissioning process. The collection of this data is crucial to the missions of AMSAT’s Fox-1 satellites. Please continue to collect data from AO-85, AO-91, and AO-92.
