Satellite communications (SATCOM) are integral part of both military and civilian communication infrastructures. Applications are being developed that require satellite communications support for mobile satellite terminals. However, both urban and rural terrain present many obstacles that block satellite signals and interrupt voice, video and data transmissions for moving military tactical vehicles and civilian vehicles. To address this real barrier to effective communication, military and civilian satellite terminals need scalable and robust mechanisms to ensure that voice, video and data communications are received correctly and in their entirety despite interruptions during transmission due to blockage caused by obstacles. This needs to be accomplished without using excessive amounts of limited SATCOM bandwidth. Leveraging extensive experience in wireless network technology, Architecture Technology Corp (ATC) will develop a system that provides blockage mitigation techniques for networks of on-the-move satellite terminals. The system will maintain the QoS requirements of multimedia flows despite satellite signal blockages.
