PLATO is a self-contained robotic observatory built into two 10-foot shipping containers. It has been successfully
deployed at Dome A on the Antarctic plateau since January 2008, and has accumulated over 730 days of
uptime at the time of writing. PLATO provides 0.51 kW of continuous electrical power for a year from diesel
engines running on Jet-A1, supplemented during the summertime with solar panels. One of the 10-foot shipping
containers houses the power system and fuel, the other provides a warm environment for instruments. Two
Iridium satellite modems allow 45 MB/day of data to be transferred across the internet.
Future enhancements to PLATO, currently in development, include a more modular design, using lithium
iron-phosphate batteries, higher power output, and a light-weight low-power version for field deployment from a
Twin Otter aircraft.
Technologies used in PLATO include a CAN (Controller Area Network) bus, high-reliability PC/104 com-
puters, ultracapacitors for starting the engines, and fault-tolerant redundant design.
