New Delhi (Sputnik) – The Indian Space Research Organization (ISRO) has downplayed the failure of three atomic clocks onboard one of the satellites of the India’s home grown ambitious Regional Navigation Satellite System (IRNSS).
The failure of three atomic clocks is not causing much worry to Indian scientists as they cited similar instance earlier this month in Europe, where three rubidium atomic clocks and six hydrogen maser clocks onboard Galileo failed.
“The problem is only with the clock system of one spacecraft. The signals are all coming, we are getting the messages, everything else is working and being used, except the stability portion which is linked to the clock,” said ISRO Chairman A S Kiran Kumar.
Rubidium atomic clocks were manufactured by the Swiss company Spectracom. However, India’s CSIR-NPL has developed and transferred the critical technology of Rubidium atomic clock for space applications to ISRO.
A model has been developed at CSIR-NPL and is undergoing further developments at Satellite Applications Center before being integrated in the payload of the Indian Regional Navigation Satellite system.
