The satellite's assembly, integration and testing is partly done by a consortium of six small firms led by Alpha Design Technologies, a Bengaluru-based aerospace firm under URSC's supervision.

A highly accurate rubidium atomic clock is part of the navigation payload of the satellite; failure of these rubidium atomic clocks was the reason IRNSS-1A was deemed unfit.

The information is then processed by the receivers to derive their own position, velocity and time.

The system provides seamless, uninterrupted services under all weather conditions.

After the failure of all three rubidium Atomic clocks on-board IRNSS-1A and the failure of IRNSS-1H to separate from the heat shield of the launch vehicle, IRNSS constellation remains incomplete without this satellite.
