IRNSS Receiver Position Estimation using Iterative Least Squares and Extended Kalman Filter

Abstract

Translate Article

The Indian Regional Navigation Satellite System (IRNSS), also known as NavIC- Navigation with Indian Constellation provides real time positioning and timing services. The NavIC receivers provide information related to both satellite and receiver. There are multiple algorithms which can be used for position estimations. In this paper, Iterative Least Squares and Extended Kalman Filter algorithms are proposed to estimate the unknown receiver position by taking clock bias of the receiver into consideration.
