This paper reports the state of works in the development of a wireless, low-cost, inertial-georeferencial system, designed to evaluate the obtainable performance in aerial photogrammetry direct georeferencing applications. It integrates an advanced tri-axial inertial sensor with a GPS and a wireless module. A low-cost camera has been also interfaced. The information management is carried out by two 8bit microcontrollers; synchronization, data handling and communication between them and the functional blocks is managed in order to optimize the data transmission throughput. In building the prototype, particular effort has been spent to minimize size and weight and to increase battery autonomy. A PC interface, allowing for parameters control and data logging, completes the system. The reported preliminary testing results point out the system potentialities and let to foresee a wide field of applications.

We have proposed optical true-time delay beam-forming system using a DCF and a multi-wavelength laser for phase array antenna. Total time delay for each wavelength band originated from group delay of a DCF and the fixed delay line. As a result, a DCF for 80 km NZ-DSF could be used to obtain the radiation angle of 180° by tuning the multi-wavelengths of laser in the proposed optical true-time delay.

In modern telecommunication and space electronic applications, RF MEMS switch components offer great potential benefits such as high isolation, low insertion loss, low power consumption, and excellent linearity characteristics. However, the high power MEMS RF switch capability remains the key problem for high power amplifiers within the system. This paper presents the development of a systematic and generic design methodology for high power RF MEMS switch. The methodology is followed by a chip layout design. In this research, the switch is designed to handle a minimum 1W incident RF signal power from 3 to 12 GHz with acceptable insertion and return losses of better than −0.1 dB and −17 dB respectively.

Wireless sensor networks can effectively reduce complexity, weight, and costs of aerospace on-board communication systems. However, it is necessary to optimize these networks in order to extend their autonomous lifetime. The use of a multihop communication strategy in a cluster-tree network is a useful mechanism to reduce the energy per packet In this paper, a distributed method based on joint channel and delay allocation is proposed to reduce the collision probability in this kind of networks. It allows us to increase the spectral efficiency of the network using many channels simultaneously. Furthermore, it coordinates the nodes to avoid beacon collisions, which is one of the main issues in this topology when the beacon enabled mode of IEEE 802.15.4 is used. This distributed strategy not only reduces the installation costs of networks with manually allocated resources, but also outperforms their performance since it adapts, both the packet routing and the resource allocation according to the channel conditions.

Tire proposed tool is based on GPS, RF prediction software, a radio and a laptop PC. The outcome is a PC based GIS tool that can be used in emergency rescue operations, where workers could form a more efficient mobile ad hoc wireless network, in which each node could visualize one another's if coverage footprints and avoid outage. Details will be presented in the final manuscript.

The impact of environmental configurations on the characteristics and performance of Radio Frequency IDenrification (RFID) passive Ultra-High-Frequency (UHF) tags was presented. Orientation and obstacle effects on the performance of an RFID system were investigated. The range detection sensitivity, the tag orientation sensitivity, as well as the RFID system reliability to the presence of obstacles have been evaluated and reported. Improved system reliability and range of detection were achieved in the absence of obstacles (free space) and degraded exponentially in the presence of such obstacles, with zero detection for metallic films. A tag orientation of 90° increased the sensitivity range by two folds while the same reliability was maintained.

Next generation technological infrastructure development requires an understanding of the emerging user needs discerned from trends in technology adoption and development. This paper explores a number of emerging needs in in-flight entertainment, computing and communications services (IFEC). These services are mostly value-adds that are more likely to succeed than just pure internet access, and some of the services also enable better in-flight service, thus reducing operating costs.
