The Nigerian fundamental triangulation network is made up
of triangulation stations connected by chains of geodetic
triangles whose angles have been observed.In the past a chain
or a par': of it was adjusted by semi-rigorous methods
with the result that it is not possible to carry out
statistical analysis and inference on the quality of the
Nigerian network,neither in part,nor as a whole-One such chain
is the R-chain network in the North Western part of Nigeria.
The aim of this work is to undertake a rigorous
adjustment of the R-chain or parts of it using the principles
of least squares. Statistical information resulting from this
will be used to assess the quality of the chain,and if found
good will also provide statistical information to be used for
this chain when the entire Nigerian network is adjusted by the
rigorous method
