Pulse-1 (space satellite)

2023: Satellite Launch

On June 27, 2023, Russia successfully launched a satellite to create quantum-secure satellite communications systems. We are talking about the development of NUST "MISIS" and the quantum startup QSpace Technologies.

The Pulse-1 microsatellite should demonstrate the possibility of using small spacecraft (MKAs) to observe the Sun in the soft X-ray range. It also houses equipment that allows you to test the transmission of information over a laser communication channel. It is noted that a small spacecraft with such functionality was launched in Russia for the first time.

The main payload of the Pulse-1 MKA is the Refos device, which is an X-ray spectrophotometer designed to obtain the spectral and integral flux of the Sun in the X-ray wavelength range. Using the device, electromagnetic flares will be recorded in the solar corona, their power and spectral composition will be determined. This data is the basis for the development of a medium-term forecast of space weather.

The second payload of the satellite is the Vector device, with which researchers are going to test the laser communication channel between the small spacecraft and the ground reception station for the first time in Russia. At the first stage, theoretical calculations will be checked and valuable data on the operation of the equipment will be obtained for further analysis. The payload is equipped with a special beacon laser, with the help of which specialists can accompany the MKA in low Earth orbit using a ground station with the necessary accuracy. Such laser space communications systems are one of the key steps toward creating quantum secure satellite communications systems.^[1]
