Satellite systems have extended the boundaries of information networking to the most remote places (far from cities and highways, in the middle of the ocean, and deep in space) far beyond the reach of any other communication systems. In addition, many emerging applications such as broadband communication in the aircraft during flight (in-cabin infotainment services), car, buses/ambulances, require communicating with satellite in motion currently referred to as SOTM (Satellite-On-The-Move or SOTM). According to MarketsAndMarkets forecast the mobile satellite market is growing from $3.45 billion (2015) to more than $5.6billion by the end of 2019, at an annual compound rate of 10.2%. The state-of-the-art high performance SOTM systems use mechanically rotating antennas or a combination of mechanical rotating structures with electronic scanning systems. Such systems are often bulky and high profile, cannot be mounted on aerodynamic bodies, and too slow in tracking. Due to large dimensions/weight and low speed, these systems cannot penetrate much larger market sectors of smaller cars and small-to-medium size aircrafts.The main challenge addressed in the proposed research is to develop a low-cost, low-profile, and highly modular satellite antenna technology platform with electronic beam-steering capability (no mechanically moving parts), which will provide a wide range of mobile users with broadband and reliable communication everywhere and anytime. The proposed technology is based on a new phase-shifting concept under investigation at the University of Waterloo's Centre for Intelligent Antenna and Radio Systems (CIARS), and once developed will also offer the most cost-effective solution to many emerging satellite networks, like OneWeb project, which are aimed at connecting the entire world.

卫星系统已将信息网络的边界扩展到最偏远的地方（远离城市和高速公路，海洋中间，在太空中深处），远远超出了其他任何通信系统的范围。此外，许多新兴的应用程序，例如飞行过程中飞机中的宽带通信（驾驶员内娱乐服务），汽车，公共汽车/救护车，都需要与目前称为SOTM的卫星进行交流）。根据MarketSandMarkets的预测，移动卫星市场的增长率从34.5亿美元（2015年）增长到2019年底的56亿美元以上，每年的复利率为10.2％。最先进的高性能SOTM系统使用机械旋转的天线或机械旋转结构与电子扫描系统的组合。这样的系统通常是笨重的，高调，无法安装在空气动力的身体上，并且跟踪太慢。由于尺寸较大/重量和低速，这些系统无法渗透到较小的汽车和小型飞机的较大市场领域。拟议的研究中提出的主要挑战是开发低成本，低调的，以及具有电子束传动功能（无机械运动部件）的高度模块化卫星天线技术平台，该平台将为各处和随时随地提供广泛的移动用户提供宽带和可靠的通信。拟议的技术基于滑铁卢大学智能天线和无线电系统（CIARS）的新相变概念（CIARS），并且还将为许多新兴卫星网络提供最具成本效益的解决方案，例如Oneweb旨在连接整个世界的项目。
