As with any other satellite navigation system the Navigation with Indian Constellation (NavIC) satellite navigation system has three segments namely the space segment, ground segment and the user segment. The ground segment of NavIC is responsible for the house keeping of the NavIC satellites as well as for performing the Orbit Determination and Time Synchronization (ODTS) of the NavIC constellation. One of the important elements of NavIC ground segment is the network of IRNSS Range and Integrity Monitoring Station (IRIMS). The IRIMS network is dedicated for continuous one way ranging of the NavIC satellites, signal quality monitoring of the constellation and for determining the ionospheric, tropospheric errors and other biases. NavIC at present operates in L5 and S bands and it is possible that in the near future there could be additional signals. Any augmentation of the NavIC signal in space warrants an augmentation of the ground segment also. It is therefore planned to augment the NavIC ground segment with an in house developed reference receiver that will cater to the augmented signal in space and provide continued support for the existing signals. This paper addresses some of the design considerations of the reference receiver that is being developed for the NavIC ground segment. |
