Evolution of Ka-Band On-the-move Terminals for Land and Maritime Broadband Communications

Evolution of Ka-Band On-the-move Terminals for Land and Maritime Broadband Communications

The development of three SATCOM On-the-move (SOTM) terminals designed to operate on the WINDS satellite is discussed. All three terminals were able to achieve a tracking error of less than 0.2 degrees and uplink data rate of at least 9Mbps when operated under worst case motion. Key design choices and improvements between the earliest and later designs are presented.

Equipping Australia’s Defence Forces: A versatile multi – satellite terminal for robust on-the-move communications

Broadband communications anywhere, anytime, anyplace can only be provided by satellite communications. But when communications is mission-critical, how can it be made more assured, resilient, and resistant to hostile or environmental interference?

Recognising that such a requirement existed, the Royal Australian Navy, through Australia’s Capability Technology Demonstration Program, worked with EM Solutions to bring such a capability to fruition.

Making the most of Ka GaN

GaN FETs offer significant benefits over their GaAs based counterparts. Higher efficiency, wider bandwidth, improved reliability and higher output powers are just some of their features. Now GaN PA MMICs are available at Ka-band. What are BUC vendors doing to make the most of this exciting new development?

This paper outlines some of the technology changes that EM Solutions is developing in order to harness the power of GaN.

NICT Winds Technical Results Paper

The National Institute of Information and Communications Technology (NICT) has developed a Ka-band mobile earth station which achieves 24 Mbps in land mobile regions using the wideband internet engineering test and demonstration satellite. The mobile earth station is installed with a dual reflector antenna of 650 mm diameter, a block up converter with an output of 20 W, and a mono-pulse tracking system with 3-axis gimbals mechanisms for satellite tracking and communications. Using this terminal, the transmission data rate of 18 Mbps were confirmed. High definition television (HDTV) transmission was also conducted using an onboard HDTV camera in suburban and expressway areas. In this test, successful HDTV transmission was confirmed under the moving conditions.

This paper was presented at the AIAA ICSSC 2015 conference organised by EM Solutions.

Achieving high data rates in nano-satellites with Ka-band technology

EM Solutions’ technologies power broadband nano-satellite communications.

The constraints placed upon small satellite design for remote sensing missions have traditionally been power availability, heat dissipation and aperture requirements. However as small satellite sensor technology approaches the 1-meter resolution threshold, data throughput is becoming a new and particularly challenging constraint on mission design.
