Eaton helps CEC modernize interplanetary communications for NASA

Summary ↓

Challenge

Provide Continental Electronics Corporation with reliable motor control to help modernize interplanetary communications for NASA’s Jet Propulsion Laboratory

Solution

A custom motor control and drives solution designed to support cooling functions for sensitive radio transmitter electronics 

Results

Successful integration in overall modernization effort targeting increased capacity for deep space data transmission.

Challenge: Modernizing equipment to support functions for sensitive electronics

Continental Electronics Corporation (CEC) was called upon by NASA's Jet Propulsion Laboratory (JPL) to modernize the largest steerable parabolic antenna in the Southern Hemisphere, located in Canberra, Australia.  This antenna is a critical point of communication for interplanetary explorations and data transmissions for spacecraft in line of sight to Earth.  It had not been updated in over 47 years and the project would help JPL add capacity to its deep space network, supporting NASA's growing number of missions.  

CEC required a custom motor control center (MCC) to support cooling functions for sensitive electronics.  This critical component would help ensure electronics remain in peak operating condition when performing the energy-intensive task of sending and receiving data billions of miles outside of our atmosphere. 

Our suppliers must be equal to the rigorous requirements and standards we expect. In this regard, Eaton contributed to the overall success of the project.

Solution: Custom-engineered with advanced communications

Due to the transmitter’s electronic components need to be maintained at optimal temperatures during every communication cycle, the Eaton team engineered a combination of MCCs and variable frequency drives to intuitively power the pumps responsible for distributing coolant liquid throughout the structure. A modular, framed design allowed Eaton’s MCCs to meet CEC’s exact control requirements within a compact footprint. The solution was also integrated with some of the most advanced and flexible industrial communication connectivity options in the marketplace with protocols that help ensure seamless interoperability with nearly every industrial control and software manufacturer. Leveraging these capabilities and expertise, Eaton met the high standard motor control specification proposed by CEC without issue.

Mission accomplished!

Eaton provided a tailored, customized, motor control solution to enable CEC to modernize the DSS-43 deep space antenna.

Following completion of the project,  JPL successfully transmitted a set of commands to the Voyager 2 spacecraft which had not been able to be performed during the downtime, and verified that they were correctly received.

Today the new transmitter systems support all Deep Space missions, including the Perseverance Mars rover and will be part of the worldwide communication system supporting future Moon and Mars missions.
