ABSTRACT: In order to comply with the
recommendations of the new mining code, as well as to
facilitate data acquisition and exchange, and to guarantee the reliability of these data, the Chemical Industries of Senegal
(named ICS) have decided to switch from their local terrestrial
reference system to the Senegalese terrestrial reference system created in 2004
and called RRS04. This move allows ICS to take advantage of new measurement
techniques such as GNSS and a more global
terrestrial reference system. A combination of geodesy with the least
squares method was implemented for the resolution of the problem and the
optimization of the solution. For this purpose, a GNSS observation campaign was carried out on selected points. The raw data
obtained were processed with the Leica Infinity 3.0 software before
being used in our calculations for the estimation of the parameters of this
passage which has many stakes for the ICS. The obtained results were then
presented, applied before being checked and validated.
