ARTSAT2:DESPATCH 3D Printed QSL Card

The ARTSAT2:DESPATCH team have sent a a 3D printed QSL card to*Michał
Zawada SQ5KTM* and the Polish team to confirm their reception of the
amateur radio signal from the FO-81 spacecraft at a distance of 2,715,228
km from Earth

On 9 December 2014, at 9:50:23 p.m. UTC we received signals from the ARTSAT
2: DESPATCH space probe, which was at this time at distance of 2,715,228 km
from Earth.

The last signals received by us from ARTSAT 2: DESPATCH were very weak, but
clearly stood out on the waterfall diagram of the monitoring program. To
avoid misinterpretation we asked for confirmation directly from the
creators of the space probe: Tama Art University and The University of
Tokyo. The data reported by us were analyzed, compared with the model and
successfully authenticated – we have received confirmation with thanks.

Important result of our work are gigabytes of data, which were sent for
further analysis to the operators of both space probes.

This result has been achieved courtesy of PIAP [www.piap.pl] which made it
possible for us to use 4.5m diameter parabolic mesh dish antenna, the
involvement of PIAP employees, the support of fellow amateurs, and of
course the understanding families of all those involved.

In our project of monitoring signals from ARTSAT 2: DESPATCH and Shin-En2
space probes , except the antenna, we used radio amateur equipment
(purchased and also of our own design), especially designed and made by us
emitter which was set in place of the antenna focus, especially prepared
software. Preparations of our ground station took us almost two weeks,
including some hours on a roof at freezing weather conditions.

Our station operators during all of seven nights were: Piotr SP5MG, Piotr
SP5ULN, Lukasz SQ5RWU and Michał SQ5KTM.
Technical support: SQ7GMO, SQ5DRC, team of a few PIAP Institute employees
Guests invited to our station: SP5XMU, SQ5NWI, SQ5AAG, and some more
persons.
