What is the MPT30Ka?

Orbit Communication Systems, a prominent provider of communication solutions, recently unveiled the MPT30Ka, a new Multi-Purpose SATCOM (Satellite Communication) Terminal designed for Satcom-On-The-Move (SOTM) applications.This compact terminal is engineered for tactical vehicles and critical mission deployments, offering robust communication capabilities in challenging environments.

Key Specifications and Design Features

Lior Rudminsky, vice President of Products and Solutions at Orbit communication Systems, detailed the MPT30Ka’s specifications at DSEI UK 2025. The terminal boasts a 30 cm dish diameter, constructed from a blend of advanced composite materials, 3D-printed components, metals, and plastics. Orbit also offers a larger variant, the MPT46Ka, featuring a 46 cm diameter dish and operating within the Ka radio band.

The system’s transmitter operates between 29.0-31.0 GHz,while its receiver functions within the 19.2-21.2 GHz frequency range. A detailed technical specification sheet is available on the Orbit Communication Systems website.

Enhanced Performance and Power efficiency

orbit attributes the MPT30Ka’s improved performance to a newly developed antenna design. This antenna delivers higher gain while substantially reducing power consumption compared to traditional electrically steerable antennas. This efficiency is crucial for vehicle-mounted and portable applications where power resources are limited. The system is designed to be “modem agnostic,” meaning it can seamlessly integrate with a variety of existing communication systems, thanks to user feedback focused on plug-and-play functionality and roll-on/roll-off capabilities.
