X-ray communication (XCOM) is an emerging laser communication technique for deep space applications. Traditional link acquisition of laser communications depends significantly on Earth support and shows little autonomy. For XCOM, a pulsar vector observation-based link acquisition method is proposed, which utilizes noncooperative pulsars in deep space as beacons to acquire absolute attitude information and accomplish link acquisition. Firstly, a pulsar vector observation model was established based on the coordinate definition of the X-ray detector and X-ray collimator model. Secondly, a modified “success-failure” pulsar vector search algorithm with two degrees of freedom was proposed to acquire the pulsar vector. With the pulsar vector and the relative attitude obtained from inertial sensors, the link acquisition pointing vector could be determined. Finally, the performance of the proposed method was evaluated using numerical experiments, and factors that influence the performance are discussed and analyzed.

“…Through detecting the concentration of powdered coal in the air to indirectly determine the dust suppression quality, such kind of technology is of guiding significance to the research and development of dust suppression quality detection technology in the transportation link. For instance, ultrasonic thickness measurement method and x-ray transmission method are able to achieve better effect and accuracy in laboratory testing [13,14], but there are some issues, including the inconsistent field application conditions and difficult testing, making it difficult to be promoted and applied in railway transportation.…”

Aiming at the low efficiency of manual sample inspection of dust suppression spraying quality in railway coal transportation, a detection system combining a high-pressure gas spraying and laser backscattering detection technology is presented in this paper. In terms of hardware, it is composed of gas excitation, powdered coal concentration detection and a control unit. The gas excitation device, including nozzle, camera and electric control platform, is designed for realizing the dust suppressant spraying quality detection by nozzle jet gas impacts on a coal surface. In terms of software, the programs for the system were developed based on the LabVIEW development platform, realizing the system parameter adjustment, detection signal display, gas excitation control and real-time data storage functions. Experimental results show that the gas pressure of the field test should be maintained at 0.9 MPa–1.23 MPa and the distance between the equipment and the target vehicle is more than 2000 mm. The proposed system can detect 3–4 times spot checks with a single carriage for the train under the speed of 3 m s−1–5 m s−1, which solves the problems of low efficiency and high risk of manual detection.

“…[2] Several small scientific facilities have been proposed to be used for the exploration of other planets, such as surface seismic monitoring stations, orbiting satellite detectors, quasar surveyors, planetary geology probes, surface-atmosphere monitors, and X-ray communication transmitter. [3,4] Because systems may travel very long distances and operate far away from a light source, i.e., the sun or another star, chemical and solar energies are not appropriate to power systems in long-term applications. [5] Thus, radioisotopes as a source of nuclear energy have become the only fuel able to reliably power these instruments to explore the solar system frontier and beyond.…”

Small distributed scientific monitoring equipment is an advanced concept in deep space exploration that requires a special power system. A micro‐radioisotope thermoelectric (TE) generator has the advantages of being of small volume, lightweight, and having a long life, which is regarded as the first choice. An annular radial TE conversion structure integrating 30 TE legs in 8.8 cm3 is designed, and a satisfactory temperature difference of 188.4 K is demonstrated. The p‐type Sb2Te3 and n‐type Bi2Te2.7Se0.3 TE thick films are prepared by screen printing, and Seebeck coefficients are 142.4 and −179.8 μV K−2, respectively. By serial–parallel stacking, modular single‐layer devices are effectively integrated on a large scale. The 900 TE legs are integrated into 15.86 cm3, which can provide a high voltage output of up to 13.2 V. When an electric heating source that simulates 3PuO2 is loaded, an open circuit voltage of 3.84 V and a maximum power of 1.26 mW can be obtained. As a demonstration, a prototype to drive a wireless sensor network is used. In the future, this kind of independent power source is expected to become a help for small autonomous and distributed scientific instruments.
