Payload Telescience Operations Centre

The Payload Telescience Operations Centre (PTOC) is located at Canadian Space Agency (CSA) headquarters in Longueuil, Quebec.

Scientists and engineers use this facility to support astronauts as they conduct Canadian science experiments on board the International Space Station (ISS).

The role of scientists and engineers on Earth

The team at the PTOC is generally composed of three people:

They are often assisted by visiting researchers from all over Canada.

How ISS science is supported from Earth

When an astronaut participates in Canadian science on board the Space Station, the support team on Earth:

  1. reviews the process before the activities take place on board.
  2. simulates the sequence of operations to ensure that all systems are working properly.
  3. simulates problems that could occur during the experiment, so that everyone is ready to react in case of unexpected events.
  4. supports the astronauts during the real event.

This procedure ensures the achievement of all scientific objectives.
