Since the 1980’s and 1990’s, GPS and INS/GPS data, respectively, have been used to support sensor calibration and orientation of kinematic primary data acquisition systems. Aerial control position and attitude observations, well-known to the photogrammetric community, are used for Direct Sensor Orientation (DSO) and combined with the traditional aerial triangulation image observations to reduce...

The research presented in this report focuses on the spacecraft simulators, Whorl-I and Whorl-II, in the Space Systems Simulation Laboratory (SSSL) at Virginia Tech. The goal of this research is to develop a program to visualize the attitude of the simulators in real-time through Analytical Graphics Inc.’s Systems Tool Kit (STK). Spacecraft missions are high-risk and highexpense; therefore, ext...

In the process of English learning, each learner has his/her own attitude towards learning. In this path, s/he should feel free to be responsible for what s/he wants and seeks to learn which shows how autonomous the learner is. This study is based on the hypotheses that there is a relationship between what the learner feels towards English language learning and his/her level of autonomy. For th...

These days, nano (1 kg – 10 kg ) and micro (10 kg – 100 kg) – satellites, which are smaller than conventional large satellite, provide space access to broader range of satellite developers and attract interests as an application of the space developments because of shorter development period at smaller cost. Several new nanoand micro-satellite missions are proposed with sophisticated objectives...
