survey, we usually use annexed traverse as special example according to practical situation and the
net usage. This requirement for this traverse is the high accuracy for the known vectors between
two point ends. Furthermore, the amount of annexed traverses cannot exceed the limits.

3. Star shape net
Star net has simple geometry graph, but the baselines of it mostly don't compose a closed
graph, so it has a bad checking ability and consistency.
The advantage of this net is that it only needs two receivers, the work is very simple, so it is
mostly used in the quick surveying as quick static orientation and kinematic orientation. This
working mode is widely used in project layout, border surveying and GIS surveying, etc.
