• Developed software for orbit determination and manoeuvre optimization of low Earth orbit satellites in swarms and formation flight, using orbital mechanics and geodesy concepts. • Created algorithms using extensive knowledge in classical mechanics, flight dynamics, linear algebra and Lagrangian formulation for analytical mechanics method, and astrodynamics. Eg. Euler method (ODE boundary problem). • Study and analysis of wireless communication channels between space satellites and Ground station antennas on Earth. • Created a MIMO wireless channel between multiple trasmitting antennas in space and multiple receving antennas on Ground station in Euclidean 3–dimensional space using Fast Fourier Transform numerical methods, and calculus. • Transmitted data from satellites in space arranged in different swarm geometries to the Ground station. • Created Linear receiving filter to retrieve data as close as possible to the originally transmitted data. • Compared each swarm geometry with channel capacity , bit error rate, SINR. • Created an adaptive filter at the receiving end to compare the transmitted data from each satellite swarm geometry. • The satellite swarms are constantly revolving around Earth in LEO orbits. The changes in adaptive filter with changes in orbital position of satellites is compared in terms of swarm geometries, BER, channel Sum Rate, SINR. • The transmitting and receving antennas are designed based on 5G and 6G frequencies. The Link Budget and RF frontend analysis is done to get antenna variables for the trnsmission and reception of signals in space. • Demonstrated expertise in ability to define, implement, validate and operate software for 6G communication network from satellites.

It is a Master project that was continued for Master Thesis in the University.• Study and analysis of orbital mechanics and orbital trajectories of satellites around Earth.• Designed a Simulation of satelite orbits in different swarm geometries revolving around Earth in LEO. Studied their orbital elements and their changes with time.• Created C codes to to add external perturbations to the satellite orbits.• Studied the changes in orbital parameters with and without external perturbations. Simulated their LEO orbits in Simulink.
