Chapter 11: Onboard Systems
How does a spacecraft meet its demanding electrical power needs? Choices of technology to meet these requirements are today constrained largely to two: photovoltaics (PV) and radioisotope power systems (RPS). The latter includes radioisotope thermoelectric generators (RTGs) such as those currently powering Voyager, and that powered Cassini.
