Underwater electromagnetic (EM) communications were investigated with fervent interest in the last century up until the 1970s. Because its range is restricted by fundamental attenuation and noise factors that must be considered as unchangeable environmental elements, significant breakthroughs were not to be expected in submarine radio communication [1];(More)
Most underwater sensor networks choose acoustics as the medium for wireless transmission. However, electromagnetic waves also offer great merits for transmission in special underwater environment. A small scale wireless sensor network is deployed using electromagnetic waves with a multi-hop static topology under shallow water conditions where there is a(More)
A small scale wireless sensor network was designed using electromagnetic technology in order to provide an underwater coastal monitoring service. The sensor nodes were deployed manually, which formed a multi-hop static topology for the network. Data delivery was scheduled via daily cycles of sleeping and waking-up. Due to the unique features of the network,(More)
Satellite flying formation missions are being prepared by more and more aerospace centers for the potentials they have. They also bring challenges like clock synchronization. This paper introduces a dedicated hardware device, General Cell (GC), which is a general micro-platform of spacecraft C&DH system, fully fits to formation flying space(More)
Most underwater sensor networks choose acoustics as the medium for wireless transmission. However, electromagnetic waves also offer great merits for transmission in special underwater environment. This paper presents part of the work carried out in a project, entitled ASTEC (Automated Sensing Technologies for Coastal Monitoring), which aims to deploy a(More)
