In this work we investigate the Bit-Error-Rate (BER) of the Infrared (Ir) Communication inside the Vehicle Equipment Bay (VEB) of the ARIANE 5. Measurements were performed to find the impact of the reflection of the infrared signal via Multi Layer Insulation (MLI) on the infrared wireless sensor network (Ir WSN) communication in the VEB. The main focus is to find the relationship between the BER and the transmitting/receiving angle depending on variation of the Ir transmitter power. A further experiment was done by varying the transmission current with a constant angle for BER estimation without adding extra special signals (e.g. Additive white Gaussian noise (AWGN)) to the transmitter. Ambient white light from LEDs and 50 Hz fluorescent AC light was superimposed in the measurement to introduce additional noise for the infrared receiver into the physical channel.

Following an article presented at WiSEE 2013, this paper presents a complete wireless sensor network based on UHF RFID technology, composed of an interrogator, a sensor tag and a radiofrequency energy harvesting system used to power the tag. The complete system has been designed for space launchers in vehicle wireless sensing using common sensors such as thermocouple, thermistor, strain gauge, pressure sensor... Equipped with its energy harvesting module, each sensor tag is able to acquire and transmit measurements at a distance of 5m from the interrogator without use of any kind of battery. Based on ISO/IEC 18000-63 standard, the specific interrogator benefits of a hardware design adapted to launcher environment, and a specific firmware made to boost the communication speed.

Since 2000, the Spanish National Institute for Aerospace Technique (INTA) has been developing the so-called OWLS technology (Optical Wireless Links for intra-Spacecraft communications). After a number of ground-demonstrations, technological developments, and in-orbit experiments, the time was ripe for a new step: the transition from the experimental to the “platform” technology. This is where the highest TRL has been achieved. OWLS has been recently applied to (A) the On Board Data Handling subsystem of OPTOS, the first fully wireless satellite, and (B) addressing the communication challenge between a sensor and a meteorological station on the Martian surface, within the Mars MetNet Precursor Mission.

This paper conducts theoretical study on employing phase-conjugation antenna array to beam microwave power from satellite to earth in the context of space solar power (SSP) applications. Our analysis reveals that, the phase-conjugation array must have aperture dimension greater than 1 km × 1 km in order to be applicable to practical SSP systems. Moreover, antenna array with such a large size does not behave as a conventional phased array, in that the power receiver on earth resides in the array's Fresnel region rather than far-field region.

Competitive single-number Life Cycle Assessment is performed between existing and near-term electrical power plants at the infrastructure level. The focus is on an alternative to current electrical power production in the US in the form of Earth-orbiting Solar Power Satellites Two. This modernized SPS2 theoretical architecture is compared to Combined Cycle Natural Gas and terrestrial solar photovoltaic fields at 5GW capacity as delivered on-site. The SPS2 configuration presented is a modest, research-driven modification to a standard model that assumes medium-high technological readiness levels for equipment and employs predicted launch costs and capacity.

Ultra-wideband (UWB) signal propagation was simulated and experimented within closed boxes with various inner volume, with a view to replace (at least partly) wired onboard data buses with wireless communications. Since multipaths depend on inner volume, it is necessary to evaluate the propagation characteristics depending on volume. Frequency-domain responses (from 3.1 to 10.6 GHz) in some closed boxes emulating a small scientific satellite were simulated and measured with a vector network analyzer. The spatial distribution of UWB propagation and its parameters were derived from the measurements. The propagation gains did not apparently depend on the inner volume. On the other hand, delay spreads were found increase with the volume.

Deep space communications could be advantageously accomplished by using distributed multiple-input, multiple-output (DMIMO) satellite links, as it has been outlined in the recent literature. One of the most critical issues is related to synchronizing both the carrier phase and frequency, affected by Doppler shift and frequency offset at local oscillators. In this work a solution for intermittent carrier and phase synchronization is proposed, considering a baseband scheme which is suitable for both software defined radio (SDR) platforms and hybrid analog-digital higher data rate systems.

A Structural Health Monitoring system to detect and identify accidental impact on the surface of any aerospace structure is developed and presented in this paper. Specifically, during an event of impact, a Non Destructive Damage Assessment & Location Estimation is incorporated to estimate the coordinates of the impact from an array of sensor information. A wireless communication system is also proposed here for transmitting the sensor information to any remote site for monitoring purpose. The proposed communication system is integrated on a prototype surface and tested for an in-lab environment. It is shown to be capable of transmitting location, time and magnitude information to a remote location in real-time.

Delay and disruption tolerant networks (DTNs) are becoming an appealing solution for extending Internet boundaries so as to embrace disruptive communications. In particular, if node trajectory and orientation can be predicted as in satellite networks, routing schemes can take advantage of the a-priori knowledge of a contact plan comprising the forthcoming communications opportunities. However, the design of such a plan need to consider both available spacecraft resources and the expected traffic which is largely foreseeable in space applications. In this context, the existing Traffic-Aware Contact Plan (TACP) procedure exploits this properties, but the computation complexity of its theoretical formulation results prohibitive for real satellite applications. As a result, we propose CPD-EA: a genetic algorithm to provide sub-optimal yet efficient and implementable contact plans in reasonable time. In particular, we describe the algorithm strategies and evaluate its preliminary performance in a realistic Low Earth Orbit (LEO) scenario demonstrating it usefulness for planning future DTN-based satellite networks.

In this paper, we study the problem of multi-user inter-satellite communications in a network of small satellites and design and implement of an optimum CDMA-based multiple access communication using Software Defined Radios. Inter-satellite links (ISL) enable small satellites to exchange information and share resources while reducing the traffic load to the ground. The ISL assist in performing advanced functions including distributed processing and autonomous applications. By utilizing the ISL in maintaining the relative distance between the satellites, navigation, and positioning accuracy is improved greatly. The ideology proposed here is to implement remote modifications in inter-satellite communication after launch using Software Defined Radios (SDRs), while accommodating an adaptive autonomous small satellite network. Remote upgrades from the ground as well as the potential to accommodate new applications and future services without hardware changes is very promising. Software defined radio-based implementation of an ISL can assist in enabling an adaptive and reconfigurable communication system, which can achieve higher data rates and modification of frequencies. In this paper, we designed and implemented a multi-user inter-satellite communication network using SDRs, where Code Division Multiple Access (CDMA) technique is utilized to manage the multiple access to shared communication channel among the satellites. This research is the first work to study and implement the utilization of SDRs for inter-satellite communications in small satellite systems.
