By Morteza Abbasi
Supervisor: Dr. Mehran Mirshams

Abstract: With the increasing expansion of interplanetary missions and space exploration, flight control, guidance, and navigation programs for space systems have become very important. In this research, we first design and develop a suitable test platform to simulate the operating environment of the spacecraft in performing orbital missions, such as orbital maneuvers, orbital appointments, connection, flight arrangement, as well as the removal of space debris; Then, we develop and explain the flight plan used for the proximity mission to an asteroid and finally the environment for performing hardware implementation tests in the ring. This research was carried out in the space research laboratory of the Faculty of Aerospace Engineering, Khajeh Nasir al-Din Toosi University of Technology. On the whole, a testbed with the capability of 3 degrees of freedom of movement (2 degrees of transfer, 1 degree of position), guidance algorithm, navigation, and closed-loop control Near an asteroid and space simulator environment was developed for interplanetary missions.

Determining the orbits of satellites is essential for planning and carrying out space projects. As in the past, the issue of determining the orbits of planets and objects in space has been considered by scientists, with the pervasiveness of space missions and the increase in the number of satellites, the need for continuous monitoring of space is increasingly considered by space organizations around the world. Also, in recent years, with the launch of satellite mega constellations and the stunning increase in the number of satellites in orbit, it has created a new challenge for astronomical observatories in imaging the night sky, which shows the importance of determining the position of satellites. In this dissertation, by examining the orbit determination methods, we have gone to the angle only orbit determination methods and using image processing algorithms, the data obtained from electro-optical instruments (including COTS) have tried to determine satellites’ orbit.

Happy Birthday, Dr. Mehran Mirshams.

SRL members celebrated Dr. Mirshams’ birthday on this very special day! They all wish him a splendid year filled with happiness, health, and success.

Happy Birthday Dr. Mirshams! We are so grateful for getting a chance to work under your supervision ❤️

The new age of Large Low Earth Orbit Satellite Constellations

Abstract:

The Satellite industry sector is going through continuous innovation since its inception in 1960s.With advancement in technology, in the space communication ecosystem we are experiencing rapid advancement. The 4th industrial revolution has started, it requires more robust and advance communication platforms to support our ambition of “Be Connected anywhere, anytime”. Various reports indicate Tens of Billion devices need to be connected over the next several years. New technological involvement requires real-time or near to real-time responses, which in turn requires much lower latency than the traditional 700ms of satellite network in Geostationary Earth Orbits (GEO). Consequently, we notice lots of focus and attention to other form of space communications and None Geo Stationary Satellite Network (NGSN)There are several numbers of providers looking on usage of MEO and LEO. Currently Star-Link is one of the front runners. This report, provides comprehensive overview of the Large Low Earth Orbit Satellite Constellations (LLEOSC), communication application with particular section on Star-link.

SRLSAT team were not selected for the engineering model phase

Unfortunately, After the presentation of the MIL phase And unlike team member’s Effort in this phase and their good result on MIL, They could not reach an agreement with the competition officials to build an engineering model.

Best wishes and luck to SRLSAT team members for their subsequent adventure in their life.✌️
