The International Amateur Radio Union (IARU) has coordinated two European
digipeating satellites that are scheduled to launch in fall 2023. At the
Technical University of Kosice in Slovakia, satellite Veronika, a 1U CubeSat,
is scheduled for launch on a Falcon 9 launcher on the Transporter 9 mission in
October 2023.

The satellite will be equipped with a 24/7 digipeater on two different bands,
as well as experimental slow-scan digital video (SSDV) transmissions. There is
an education and outreach mission planned to involve Slovak grammar and high
schools, and to transmit special CW and AX.25 messages on several special
occasions. The satellite will be equipped with a novel Attitude Determination
and Control System (ADCS) subsystem, including electromagnetic actuators and a
global navigation satellite system (GNSS) receiver. This will also help to
identify the satellite during the first days and weeks of orbit.

The satellite will communicate using Spacemanic's[1] well-known Murgas
transceivers (BDSat-1, BDSat-2, Planetum-1). Altogether, Veronika will provide:
AX.25 telemetry, a CW beacon, a digipeater, AX.25 and CW messages on special
occasions for community engagement, experimental SSDV transmissions, SatNOGS[2]
integration, a decoder, and a dashboard. A downlink on 436.680 MHz has been
coordinated, and it will use 9k6 G3RUH AX.25 and a CW beacon. A SpaceX launch
on the Transporter 9 mission will send the satellite to a 500/600-kilometer
polar orbit.

The Romanian Federation of Amateur Radio (FRR[3]) is preparing the ROM-3 for
launch in October or November 2023. ROM-3 is a 50 x 50 x 100-millimeter picoSAT
with three missions and objectives. Its primary mission is to act as a digital
amateur radio repeater. Its secondary mission is to transmit low-resolution
SSDV images in a Gaussian frequency shift keying (GFSK) mode. The tertiary
mission is to transmit a CW beacon that will help amateur radio operators
detect the presence of the satellite and measure basic properties of the
signals, such as its strength, fading due to spinning, and Doppler to measure
speed. A downlink on 436.235 MHz has been coordinated for 20 WPM on CW, 500
(bps) GFSK telemetry, and 5 (kBps) GFSK SSDV. A SpaceX launch will send ROM-3
into a 500-kilometer polar orbit.
