SB SAT @ AMSAT $ANS-175 02 Delfi-C3 Satellite Integration for Planned Autumn Launch

AMSAT News Service Bulletin 175 02

From AMSAT HQ SILVER SPRING, MD June 24, 2007 To All RADIO AMATEURS BID: $ANS-175 02

Wouter Jan Ubbels, PE4WJ, Delfi-C3's project manager of electronic systems and communications at the Delft University of Technology in the Netherlands reports that their satellite is being integrated and tested in preparation for launch in September or October, 2007

The Delfi team has posted photos of the satellite integration work at: http://www delfic3 nl/photoblog/

Delfi-C3 is a 3-unit CubeSat carrying redundant radio transceivers, connected to the antenna system by a hybrid combiner Both trans- ceivers consist of a UHF front end, a command receiver, linear IF, telemetry generator and the final stages capable of 400mW RF power

Delfi-C3 contains no batteries because it's primary mission is to perform a solar cell and sun sensor experiment so the spacecraft will only be active when in sunlight

The first three months of the mission will perform the science mission, in which the spacecraft will be transmitting 1200 bit/s AX 25 telemetry on the primary or backup VHF downlink (See http://www delfic3 nl for frequency information ) Telemetry will be transmitted once per second

A Java application will be available for download from the website to display telemetry in real time, and upload it to Delfi's central server in Delft A soundcard application in Java is planned to be available to decode the BPSK signal The MixW software package will also be compatible with the telemetry signal

After three months, the linear transponder will be activated, with a 40kHz bandwidth In transponder mode, a CW beacon will be active instead of BPSK telemetry It will transmit a message saying "hi hi de delfi-c3 delfi-c3" Since Delfi-C3 will transmit with only 400mW of downlink power, earth stations will need to prepare a good receive system

TLE's will be anounced on the website (http://www delfic3 nl) once they are available Preliminary parameters of the orbit are: + altitude: 630km circular + inclination: 97 91 degrees + sun-synchronous
