The NVS-01 carried navigation payloads L1, L5 and S bands.

The satellite would ensure the continuity of navigational (NavIC) services and also provide new service in L1 band.

Interestingly, for the first time, an indigenous atomic clock was flown in NVS-01.

An atomic clock is an extremely accurate type of clock which is regulated by the vibrations of an atomic or molecular system such as caesium or ammonia.

L1, L5 and S bands

The GPS L1 band (1575.42 MHz) has turned to be the most important band for navigation purposes.

The two sorts of services given by the Indian Regional Navigational Satellite System (IRNSS) satellites are Standard Positioning Service (SPS) and Restricted Service (RS).

Both services will be given at two frequencies of L5 (1164.5 MHz) and S (2472.5 MHz) band.
