Non-averaged regularized formulations as an alternative to semi-analytical orbit propagation methods
, 2019 This paper is concerned with the comparison of semi-analytical and non-averaged propagation methods for Earth satellite orbits. We analyse the total integration error for semi-analytical methods and propose a novel decomposition into dynamical, model ...

Democratizing LEO Satellite Network Measurement
ACM SIGMETRICS Performance Evaluation ReviewLow Earth Orbit (LEO) satellite networks are quickly gaining traction with promises of impressively low latency, high bandwidth, and global reach. However, the research community knows relatively little about their operation and performance in practice. The obscurity is largely due to the high barrier of entry for measuring LEO networks, which requires

First LEO Satellite Built in Turkey: RASAT
2007 3rd International Conference on Recent Advances in Space Technologies, 2007 BiLSAT* project was the first step to initiate and to improve satellite technologies in Turkey and it covered all major steps to establish the necessary infrastructure in Turkey to design, build and test a LEO satellite entirely in the country. As a second step, RASAT project has been initiated in year 2004. Except for some systems; like imaging system
