4 1. Preface After a brief discussion with our technical supervisors in this project; we have agreed that a pre-study is unnecessary. We have been working with this project since January 2001 and we all have a pretty good idea about what it involves. There have been made several reports on the subject. In the diploma there have been added three subjects which will be studied in dept. We will also deliver a brief abstract on the previous reports together with a work flow sheet, and a small presentation of what we are doing right now. We will also present the three special topics to be able to accomplish the demands on Master of Science diploma.

5 2. Introduction We are a group of three students at HIN; which is only a small part of a total of 25 students divided between three different Universities (HIN, HTNU and NLH). The purpose of this project (beside constructing and launce the first Norwegian student satellite) was to gain a better cooperation between the different Universities in Norway together with increasing the interest of science study in high school. 3. Concept ncube is a Cube Sat, a concept developed by Stanford University. The concept is based on a fixed size satellite, and a standard launch method (p-pod). The satellite must not exceed these limits. Size: 10*10*10 cm Weight 1 kg Picture 1: Shows a CubeSat

6 4. A brief summation of our previous work 4.1. Power Supply When we were promoted to this task in January 2001; or main task was to make some suggestions on a technical solution on the power supply part, and deliver a report to Norsk Rom Senter (NRS) the 1 July (Technical solution). There were made three different solutions all based on switch mode power supply, and a micro controller which will handle the power management. Since 1 July 2001, one of the solutions was chosen, and upgraded several times. There have also been bought several components which we have tested in the laboratory, and documented in a report delivered to HIN January 2002 (Fase 3). Between these reports we have been participating in several work shops in Narvik, Trondheim and Oslo. Revues have been done on our work to be able to integrate the other sub systems. In these days the first over sized circuit board is designed and produced. The power supply block schema will look like this: Picture 2: Shows a block schematic overview of the Power Supply circuit board. The chosen components and voltage, current and temperature sensors are displayed. The different currents and voltages are also displayed.

7 4.2. Backplane Beside the power supply circuit board, the backplane on satellite is also produced together with Egil Eide. The backplane will be like a motherboard on a PC. It will contain all the connectors connecting the different subsystems together in the satellite. The backplane circuit board will be two of the total four layer power supply circuit. The backplane is also under construction and will look like this. Picture 3: Shows the top side of the Backplane circuit board. All the connectors from all of the subsystems, the solar cells and the antennas are displayed.

8 5. Special topics These tasks should contain: - Literature study - Analyze of the existing topologies with focus on demands and challenge. - Construction of a practical model and testing 5.1. Power management Structure with focus on reliability This task will be very theoretically. It will document on how the power management should be constructed to be reliable and well structured. The power management on board the ncube satellite is a soft real time system, so there is no room for malfunctions, but no hard. This task should survey what could go wrong in the complete power supply system. Are there other ways to built it to get it more reliably, redundancy? 5.2. DC/DC power converter/ power valve structure, sensitivity analysis, evaluation of EMC The task is mainly a theoretical one. To study the structure of dc/dc converters and make sensitivity analyses. This is to study how to make dc/dc converters more stable and reliable. One part is to look at the EMC problems, how to shield the converter from being disturbed by other systems and to make sure not to disturb Hardware in the loop preparation for simulation/ testing in realistic environments. The task with hardware in the loop is to build and program a realistic environment for testing the power supply system on the satellite. This is made by connecting the different inputs and outputs on the satellite to simulated inputs/outputs in dspace. dspace is programmed with matlab/simulink. The different inputs to the satellite are temperature and sunlight, outputs is different subsystem loads. The I2C data communication busses are divided in one output bus and one input bus.
