Gravity field data processing examples
--------------------------------------

These examples show how to load and process different types of gravity field data.

Gravity field error analysis
-------------------------------------

Here, the utilities of the observation module are showcased. It consists of an analytical gravity field error methodology 
based on the lumped coefficients' theory (Colombo, 1984).

Single satellite pair
~~~~~~~~~~~~~~~~~~~~~~

These examples investigate the gravity field recovery capabilities of inter-satellite range observations for a single-pair 
collinear formation. Some fundamental properties of the analytical methodology are also described here.

Multi-pair constellations
~~~~~~~~~~~~~~~~~~~~~~~~~

These examples analyse the capabilities of multi-pair satellite constellations. Only inter-satellite ranging in a collinear
formation is considered. Crucial mission design aspects are observed, such as the impact of non-polar inclinations, ground-track 
policies or the inherent anisotropy of the gravity field solution for such formations.
