Executive Summary : | Basically we solicit the development of a unified and versatile software tool for processing NavIC data. The versatility will lie in offering one common applicationon different types of NavIC receivers, in network or standalone mode with common data file format for various objectives, including preprocessing of data, advanced post processing of data and analyses. The features will include: A data extraction module for identifying and extracting the relevant data from the acceptable raw NavIC file format(s) provided from a single or multiple stations, apre-processing tool which will handle receivers’ measured variables by applying all necessary corrections and after compensating for drags and atmospheric loading etc. and do data reductions, a processing module, that can derive the carrier phase based derivatives from the phase measurements, handle cycle slips, resolve integer ambiguity and also augment the variables with auxiliary INS data, a navigation module that can and derive navigation outputs (PVT) using different, modes of estimations including the carrier phase based differential positioning algorithms for multiple stations scenario. A derivation tool that can derive the scientific components like the Ionospheric and tropospheric content variations, scintillation strength, multipath components, etc. and provide their simple statistics An export tool, which creates files for exporting to other programs in pre-defined formats, all the outputs obtained and derived, this will facilitate combining all available knowledge and mathematical models to obtain common unified goals. |
