21-Julio-2014. Informacion de Ignacio, LU1ESY:
Mani VU2WMY publico esta noticia: Con el corazon apesadumbrado, les comunico con tristeza, que nuestro angelito 'HAMSAT VO-52' no sera mas capaz de ofrecer sus servicios a la Fraternidad Amateur.
HAMSAT VO-52 sucumbio en el espacio el 11 de julio de 2014, mientras estaba en su 49,675 th orbita, debido a la falla de las baterias de iones de litio a bordo que han alcanzado su fin de vida util.
Segun la ultima telemetria recibida, el ordenador de a bordo repite al modo de 'Reset' debido a la falla de las baterias. Por lo tanto, se decidio no esperar ningun servicio mas de HAMSAT VO-52.
"Desde el 11 de julio que todos los esfuerzos han sido realizados por los controladores de la nave aqui en ISTRAC Bangalore (India) para revivirla a la vida, pero sin suerte."
Aunque es dificil, los diseñadores y controladores de HAMSAT VO-52 insisten en que ha llegado el momento de dejar libre al pequeño angel en el espacio, para ir a la deriva por su cuenta a partir de su cuidado y custodia'.
Por lo tanto, hoy 21 de julio 2014, la ISRO ha dado de baja 'HAMSAT-VO52' oficialmente. El Satelite VO-52 de AMSAT-India, lanzado el 5 de mayo de 2005, dejo de funcionar el 11 de julio de 2014.
Desde hace mas de 9 años que resulto ser un recurso valioso para las comunicaciones de la comunidad de radioaficionados.
Pasted below is the message from Mr. R. Suresh, Mission Director:
HAMSAT, the first small satellite by ISRO has been Decommissioned after nearly a decade of service to the World Ham community.
A true masterpiece among small satellites, designed for one year mission life, but exceeded all expectations by serving for almost 10 years.
A truly autonomous satellite, with 'Zero maintenance' in terms of Mission operations, it provided a springboard to test many new concepts such as BMU. LI-ion based power system, automatic Spin rate control and Auto SAOC for maintaining the Satellite attitude without any ground commanding.
HAMSAT known as 'OSCAR-52' among the Amateur HAM operators has been very popular because of its high sensitivity receiver and strong transmitter.
Indian Radio Amateurs on many occasions conveyed to us that they have been greatly honored to share the adulations showered on ISRO and INDIA by the International Radio Amateur for gifting this wonderful satellite "HAMSAT".
I take this opportunity to applaud the HAMSAT teams at ISAC, ISTRAC and other centre for their efforts and support, which has made ISRO proud among the HAM users across the globe.
VO-52 (HamSAT)VUSat OSCAR-52 (VO-52 HAMSAT) is a microsatellite providing satellite based Amateur Radio Services to the national (India) as well as the international community of Amateur Radio Operator.
Launched as an auxiliary payload on PSLV-6 by the Indian Space Research Organisation (ISRO), along with CARTOSAT-1, the 42.5 kg VO-52 will meet the long felt need of the Amateur Radio Operators in the South Asian region who possess the required equipment and operate in the UHF/VHF band based satellite radio communication.
One of the transponders of VO-52 has been developed indigenously involving Indian HAM?s with the expertise of ISRO and the experience of AMSAT-India. The second transponder has been developed by Dutch Radio Amateur Operator and Graduate Engineering student William Leijenaar PE1RAH from the Higher Technical Institute, Venlo, Netherlands.
