Delfi-C3 Satellite Integration for Planned Autumn Launch

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

+ Clive G3CWV's OSCAR-11 report for the week of 16 June 2007 summarizes
  operations as, "No signals have been received from the satellite's 
  145.826 MHz beacon because it remains in eclipse. Listen for signals
  starting around August 20."

+ F.Costa, CT1EAT, has a QSL for auction from Owen K. Garriott (W5LFL), 
  the first radio amateur who operated from space, during the STS-9 
  mission in 1983. Please see photos at http://ct1eatsale.no.sapo.pt/
  He  will acept bids, in EURO currency, until 00.00 UTC 25 June 2007. 
  The highest bidder will donate the amount for an AMSAT/ARISS project 
  of their choice.  He will send the card to the winner for free via 
  registered airmail. Please send your bids to ct1eat at amsat.org.

+ Peter Guelzow, DB2OS reported the AMSAT-DL/IUZ team received congrat-
  ulations from the Voyager Flight Team on their successful reception
  of the furthest manmade object in space.  The message read, "Congratu-
  lations on your successful downlink acquisition of Voyager 1 at your 
  20 meter tracking station.  Acquiring such a distant object is a 
  remarkable achievement, especially for an amateur team.  Thank you 
  very much for your interest in Voyager."  Peter summarizes, "It also 
  demonstrates now officially that the 20m dish is good enough to support 
  the AMSAT P5-A Mission to Mars."
