Amateur radio mission with digital repeater, SSDV image transmission and CW beacon.

Description

ROM-3 satellite has the following three missions and objectives. PRIMARY MISSION is a DIGITAL REPEATER. ROM-3 will act as a digital amateur radio repeater. Amateur operators will be able to upload a message to the satellite and it will transmit it to the ground once.

SECONDARY MISSION is SSDV Image Transmission. ROM-3 will transmit a low-resolution SSDV image in GFSK Mode.

TERTIARY MISSION is CW BEACON Transmission. The satellite will send a Morse Code identification. This will help amateur radio operators to 1) detect the presence of the satellite and 2) measure basic properties of the signals: strength, fading (spin), Doppler (speed), etc. ROM-3 will act as a digital repeater for the radio amateur community, and it will also send low resolution images from Low Earth Orbit in SSDV modulation. Amateur radio operators will be able to actively participate by receiving the signal and decode the image.

Results

ROM-3 waited its turn in the deployer for 72 hours, at temperatures ranging from plus 40 to minus 80 degrees Celsius. Concerns about the batteries' ability to withstand an extended time were confirmed, and the deployer did not open on the first attempt. The launcher mechanism from Alba Orbital did not work, and ROM-3 remained stuck inside, alongside the other satellites, as reported by Agerpres. From that moment, the ground team constantly calculated the battery's potential, which faced cosmic cold beyond the design limit.

“On Monday, November 28, at 11:25, Alba Orbital made the second attempt to open the launcher, and it succeeded. ROM-3 was launched into orbit and is now operational. It has already transmitted the identification data package. After a few days to regenerate its energy using solar power, the satellite will begin transmitting according to the mission,” a statement said.
