During the procurement procedure, the following objectives shall be pursued by the contracting authorities in their calls for tender:

1. (a)

   to promote the widest and most open participation possible throughout the Union by all economic operators, in particular by new entrants and SMEs, including through encouraging recourse to sub-contracting by the tenderers;

2. (b)

   to avoid possible abuse of a dominant position and reliance on a single supplier;

3. (c)

   to take advantage of prior public sector investments and lessons learned, as well as industrial experience and competences, including that acquired in the definition, development and validation and deployment phases of the Galileo and EGNOS programmes, while ensuring that competitive tendering rules are complied with;

4. (d)

   to pursue multiple sourcing wherever appropriate in order to ensure better overall control of the Galileo and EGNOS programmes, their costs and schedule;

5. (e)

   to take into account wherever appropriate the total cost over the useful lifecycle of the product, service or work being tendered.
