WHO IS DAVID FLORIDA?

  • One of Canada's prime pioneers in space research

  • Was director of the Canadian National Space Telecommunications Laboratory, manager of the International Satellites for Ionosphere Studies (ISIS) program and manager of the Communications Technology Satellite (CTS) or HERMES program

  • The laboratory was named after David Florida in honour of his achievements

- Thermal performance of the spacecraft is tested

- Makes sure the spacecraft can handle intense temperatures

Thermal Balance Testing

WHEN, WHERE & WHY THIS LABORATORY WAS BUILT

Thermal Vacuum Testing

- typically occurs in a space simulation chamber

-Chambers such as TV1, TV2, TV3 etc.

- used to test parts of spacecrafts

- ensures that a spacecraft can last the journey in space

International Affairs

  • September 29th, 1972
  • West end of Ottawa, in Shirley's Bay
  • It is operated CSA, also known as the Canadian Space Agency.
  • The government supplies the laboratory with specialized rooms and equipment.
  • Ability to perform thermal balance.
  • Able to handle hot temperatures.
  • Able to perform numerous task and experiments.

  • In the David Florida Laboratory, these rooms are used to construct satellites and other space hardware.

TWO CLASS 100,000 CLEAN ROOMS

  • Previously tested satellites for Brazil, Indonesia and the European Space Agency
  • Olympus
  • Other offshore programs include: Indostar, Optus C, BSAT 2A, 2B, 3C and CMBstar in addition to the many subsystems from other international satellites

ANECHOIC CHAMBER

  • chambers that reduce the amount of reflection or reverberation of the various types of waves, such as radio frequency and microwaves

WHAT IS THE PURPOSE OF THIS LABORATORY ?

The DFL is capable of:

- Thermal vacuum testing

- Vibration testing

- Thermal balance testing

- Modal testing

EXAMPLES OF CHAMBERS AND EQUIPMENT

  • To check the safety of equipment
  • To use numerous amount of tests to see the safety on sending the equipment to space
  • Anechoic chambers
  • Space simulation chambers
  • Shielded rooms and radio frequency equipment
  • Two Class 100, 000 clean rooms

Types of Tests

SPACE SIMULATION CHAMBER

  • There are three space simulation chambers
  • largest chamber is 7 x 10m deep with an area of 22 x 35 feet
  • largest chambers are for performing thermal vacuum & thermal balance testing
  • small chamber is used for performing outgassing tests

- tests spacecraft parts to see if they can withstand the force of exiting/entering earth's atmosphere

Vibration Testing

SHIELDED ROOMS &

RADIO FREQUENCY EQUIPMENT

  • Electromagnetic Compatibility (EMC) - how well a device/system is able to work within a electromagnetic environment without causing electromagnetic interruptions that effect the operation of other electrical products in that environment.

- Type of vibration testing

- Tests the natural frequencies, natural mass and natural shape of the spacecraft in space

  • The Government
  • Communication Research center and the National Research Council of Canada’s Acoustic Test Facility for stimulating launch environmental characteristics
  • Operational infrastructure to ensure activities run smoothly in the lab

Modal Testing
