My transponder on
HAMSAT (aka VUSAT)
An improved version of my MODE-B transponder design will fly as a secundary payload on board of the Indian HAMSAT, or in amateur world better known as VUSAT (VU = Prefix of India).
The satellite was scheduled to be launched into space on 15 october 2003 on board the Indian PSLV-C5 Mission as an auxiliary satellite. Unfortunatly the satellite has not been launched because problems have been found during the final tests.
I can and do not give any information about the situation of the satellite right now, but to the world I want to show some pictures of the my transponder that has been choosen to fly on the HAMSAT.
This is a picture of me with the MODE-B flight-model in my hands.
The picture is taken at the day I send the transponder to ISRO.
The MODE-B flight model under final test at my home in The Netherlands.
On this picture you can see Mr.Nagesh (VU2NUD: Founder of AMSAT-India) and me in front of the HAMSAT, at ISRO in Bangalore, India.
The little black-painted box we are pointing at is my MODE-B flight-model.
