GNSS' space vehicles are modern versions of lighthouses, but with better visibility. Each satellite is a reference point, and if we know our distance to several reference points,
we can compute our location, just as mariners do when they see a couple of lighthouses. For each in-view satellite \f$i\f$ of system \f$s\f$, we can write:
\f{equation}{\label{eq:pseudorange}
\rho_i = \sqrt{ \left(x^{\text{Tx}}_i - x \right)^2 + \left(y^{\text{Tx}}_i - y \right)^2 + \left(z^{\text{Tx}}_i - z \right)^2}+c\Delta t^{(s)}+\sigma_{e},

and \f$\sigma_e\f$ gathers other sources of error. Since the receiver needs to estimate its own 3D position (three spatial unknowns) and its clock deviation with respect to
the satellites' time basis, at least \f$3+N_s\f$ satellites must be seen by the receiver at the same time, where \f$N_s\f$ is the number of different navigation systems available
(in-view) at a given time. Each received satellite signal, once synchronized and demodulated at the receiver, defines one equation such as the one defined above,
forming a set of nonlinear equations that can be solved algebraically by means of the <a href="http://navipedia.org/index.php/Bancroft_Method" target="_blank">Bancroft algorithm</a> or
numerically, resorting to multidimensional Newton-Raphson and weighted least square methods. When <i>a priori</i> information is added we resort to Bayesian estimation, a problem
that can be solved recursively by a Kalman filter or any of its variants. The problem can be further expanded by adding other unknowns (for instance, parameters of ionospheric and
tropospheric models), sources of information from other systems, mapping information, and even motion models of the receiver. In the design of multi-constellation GNSS receivers,
the vector of unknowns can also include the receiver clock offset with respect to each system in order to take advantage of a higher number of in-view satellites and using them
