“…Two of the full FPGA designs require the programmer to implement the majority of the programming in a PowerPC [8,35], rather then allowing the programmer has the option of implementing some or all of the processing utilizing a real time operating system, or taking full advantage of parallel processing capabilities. Although the presented work in [39] implemented a full FPGA processing system for control of a Satellite rather than an small scale or micro vehicle, the full parallel processing capabilities of the Xilinx chip was utilized and analysis indicated good timing and parallel communication could be maintained.…”

Diversity in unmanned vehicle designs and control as well as diversity in existing autopilots lead to major compatibility issues among different platforms. The small number of different autopilot designs currently available in the market and their limitations, justifies the rationale for proposing design of a new modular, flexible, easy to integrate autopilot, suitable for multiple platforms. A discussion and comparison of the state of the art in autopilot research is presented, followed by the introduction of an autopilot design that will provide a novel and wellneeded processing platform for unmanned systems. The design is fully integrated with MATLAB/Simulink allowing for both simplified high level programming and hardwarein-the-loop capabilities, and provides a flexible FPGAbased platform that maximizes parallel processing and allows for analog signal conditioning that can be modified through digital communication from FPGA processor.

The goal of this paper is to describe the capabilities and application methods of Ka-band communication systems for small satellites indicating contributions to future advanced communication networks and Earth observations. This study is based on the actual experience on the design of the Ka-band high-speed communication system of the small satellite Flying Laptop, which is developed at the Institute of Space Systems of the Universität Stuttgart. The objectives of the Ka-band communication system is to demonstrate high-speed communications with a data rate of up to 500 Mbit/s as well as to conduct scientific Earth observations. Flying Laptop satellite is also equipped with a Ku-band signal transmitter. The attenuation of the two transmission signals in Ka-/Ku-bands are measured with ground stations to estimate the local precipitation rate. The mathematical background and operational scenario of this measurement is summarized. The received Ka-band transmission signal is measured in different meteorological conditions to identify attenuation characteristics of the Ka-band signal due to rain, clouds, trace gases and so forth, which is of great interest for utilization of Ka-band frequencies for future broadband communications.

The goal of this paper is to describe the development of a hardware-in-the-loop simulation and verification environment for Field Programmable Gate Array (FPGA) based on-board computing systems. The underlying simulation environment is the Model-based Development and Verification Environment (MDVE). MDVE is an infrastructure for model-based engineering developed by EADS Astrium. A simulation environment based on MDVE was developed at the Universität Stuttgart. Recently, the demand on applying new high density FPGA technologies for innovative spacecraft on-board computing systems is rising. The small satellite "Flying Laptop" which is built by the Universität Stuttgart is the demonstrator of a FPGA-based on-board computer. In order to develop and verify the hardware and control algorithm of the computer, an extended simulation interface between MDVE and FPGA-based computing systems is established. This environment is capable of software verification and real-time simulation/verification configuration, and enables not only on-board software development but also functional real-time hardware evaluation of all the satellite components under precise space environment models. This paper describes the detailed implementation of this simulation interface and illustrates the obtained simulation results on attitude control algorithm verification and power budget calculation as well as communication timing analysis, which ensure the validity of the implementation.
