Celestia Callisto to supply cryogenic LNAs for the Sardinia deep space antenna upgrade

Celestia Callisto has contracted with OHB Digital Connect to support their project to upgrade the Sardinia Deep Space Antenna.

 

The Sardinia Deep Space Antenna (SDSA) shares part of the infrastructure of the Sardinia Radio Telescope (SRT) but also has its own equipment and a dedicated control centre to ensure communication with spacecraft for Near Earth and Deep Space missions.

 

OHB will be installing Celestia Callisto’s Cryocooled Feeds cryogenic LNAs in X and K bands for the Deep Space chains as part of the ambitious project. These Cryocooled units are each equipped with dual Sumitomo Heavy Industries cold heads, providing continual service and no maintenance down-time.  

 

The cryo units are already installed in all three of ESA’s Deep Space antennas, doubling the antenna performance thanks to the improved reception quality.

 

For the Near Earth chains, Celestia Callisto will additionally supply their Cryogenic Compact LNA units in X and K bands. These units are plug-and-play cryogenic LNAs, offering up to 10 years of maintenance-free operation. The Compacts will offer a significant improvement in noise temperature while reducing down time and operational effort.

 

“As specialists in creating advanced front-end solutions for ground station manufacturers and operators that enhance the performance of radio antennas, we are well placed to deliver the technology required for projects like this where durability, uninterrupted service and robust operation are prerequisites,” says Celestia Callisto Sales Manager, Jennifer Bernard.

 

“Our team is working alongside those from OHB Digital Connect, Telespazio and the Italian Space Agency (ASI), to provide the solutions they need, based on our specialist knowledge of advanced RF technologies and commitment to excellent customer support,” she says.
