The electronics for the Rosetta Lander sub-system ADS consists of two PCBs (Printed Circuit Boards). One is the Controller Board and the other is the Driver Board.
The Controller is a processor board for the Rosetta Lander (RoLand) sub-system ADS, it is derived from the ROMAP DPU Board (a RoLand instrument developed by the Oesterreichische Akademie der Wissenschaften, Graz). It is based on the RTX2010 processor from Harris, successfully used in various space experiments. The Controller Board is designed to meet the very limited physical resources of Rosetta Lander concerning dimension, mass and power consumption. An overview of the Controller Board is shown in figure 1, the context diagram is shown in figure 2. This block diagram shows the design for the Flight/Spare/Engineering Unit and does not contain the technological serial terminal link of the Lab Model.
The Driver Board contains the power components and the level shifters for the sensors.
The Qualification Model (QM) of the Controller/Driver is thought to be a compatible development and test platform for the ADS hard- and software. It includes all the functionality of the final Flight Model (FM).
