Earth Observation with the Flying Laptop – a small satellite of the University of Stuttgart

چکیده
The Institute of Space Systems plans to launch the micro-satellite Flying Laptop into a sun synchronous orbit at the end of 2006. The satellite will be equipped with a camera payload system operating in the visible and near infrared spectral range as well as in the thermal region. This payload will be used to monitor the Earth surface with a ground sample distance (GSD) of 25 m in the visible and near infrared domain and with a GSD of 50 m in the thermal region. In all spectral regions mentioned above the Bidirectional Reflectance Distribution Function (BRDF) and the Temperature Directional Distribution Function (TDD) respectively will be measured using the target pointing mode. In addition, the transmission of the signal of communication Ka-band can be used to collect a data set describing the attenuation of the Ka-band under different weather conditions in Central Europe. Under rainy conditions, we will test a new method to measure the rain rate exploring the concept of differential absorption of the Kaand Ku-band signals due to presence of rain in the intervening atmosphere.

متن کاملScheduling a constellation of agile earth observation satellites with preemption
In this paper, we consider a scheduling problem for a set of agile Earth observation satellites for scanning different parts of the Earth’s surface. We assume that preemption is allowed to prevent repetitive images and develop four different preemption policies. Scheduling is done for the imaging time window and transmission time domain to the Earth stations as well. The value of each picture ...
متن کاملAttitude Synchronization Control in Satellite Formation Flying in the Presence of States Measurement Errors
This paper presents a novel attitude synchronization framework for tracking control of multiple identical/heterogeneous satellites in formation flying with connected communication graph. The main contribution of the paper is considering sensors' measurement error to derive control gains. Moreover, the proposed strategy need no angular velocity communication. Nevertheless, the tracking synchroni...
