## Technical solution n°3: mixed nodal system

**A combination between:**

Autonomous nodes supplied with solar panel and internal battery

AND

Nodes supplied with a combination of external and internal battery

Geospace (USA)</figcaption></figure>

Swapping digitizers is still required for data retrieval

BUT

Higher Autonomy of autonomous nodes

=

SD memory card capacity (9 months @ 250Hz)
