Traditional spacecraft design focuses on function implementation and lacks the consideration of testability. Spacecraft integrated test relies on telemetry and command. The test cycle is long, the test efficiency is low and the cost is high. The traditional test mode can’t adapt well to the needs of spacecraft batch manufacture. Through Model-based BIT technology, civil automobiles and airplanes have established on-board diagnosis system and on-board maintenance system, which greatly improves the ability of rapid maintenance and functional reconfiguration. Referring to the civil rapid electrical inspection technology, the spacecraft self-test models are designed from two aspects of behavior model and structure model, so as to enhance the capability of spacecraft rapid inspection.

Unmanned Aerial Vehicles (UAVs) are becoming widely used in the age of intelligence, and high-precision position sensing becomes a premise for UAVs to perform various tasks. The commonly used Global Navigation Satellite System (GNSS) is vulnerable in buildings, mountains, woods, indoors, etc. due to the occlusion and interference of signals. Based on Ground-based High-precision Local Positioning System (GH-LPS), the paper proposes a tightly-coupled GH-LPS/INS integration method using carrier phase residual to solve the problem caused by GH-LPS base stations’ unsatisfactory layout. MATLAB simulation with real flight test data proves the integration method enabling the system to maintain a reliable centimeter-level precision.

The main purpose of this paper is to calibrate the detection efficiency and energy linearity of a hard X-ray imager (HXI), one of the payloads on the ASO-S satellite. In this experiment, HPGe calibrated by radioactive source was used as the standard detector, and the experimental device used was a double crystal calibration device. The experimental method is to first measure the single energy peak of the corresponding energy point with a standard detector, and then use the HXI LaBr3 crystal detector probe to obtain the same single energy peak. It should be noted here that in order to eliminate the statistical fluctuations and other factors, we set the detection time of both detectors to 1000 seconds. Then, the dobule crystal parallelism is detuned (ie, non-parallel) to measure the unfiltered background and the electronic noise. Finally, the open source software Root is used to perform relatively clean single-energy X-ray beam data obtained after subtracting the background data of the beam.

Isolated handheld oscilloscope is an indispensable measuring tool in the measurement. It has the characteristics of portability, flexible utilization and high safety performance. Conventional handheld oscilloscopes isolate the analog channels through transformers or optocouplers, but the bandwidth of oscilloscopes is limited due to the bandwidth limitations of the transformers and the drifting characteristics of the optocouplers. This paper presents a new isolation scheme through digital channels. Because the digital isolation chips can transmit at large rate and perform multiple channels in parallel, the transmission rate can theoretically unlimited grow. The bandwidth of the oscilloscope is only related to the analog channel. By means of digital channel isolation, the bandwidth of the isolated oscilloscope is not affected by the isolation channel, and reaches the maximum bandwidth of the traditional non-isolated oscilloscope. At present, the isolated oscilloscope by analog channels on the market has bandwidth of 200 MHz.However,the bandwidth of the non-isolated oscilloscope has reached 500 MHz or even 1 GHz. Based on this scheme, a dual-channel isolated handheld oscilloscope is designed with single channel sampling rate 2GSa/s and 300MHz bandwidth. The isolation between oscilloscope channels security level can reach CAT II 1000V, CAT III 600V. Its bandwidth is larger than the handheld oscilloscope on the analog channel isolation in the markets.

Fault prediction plays a significant role in enhancing the safety, reliability, and stability of distribution network. However, the problem of enormous time-series data and discrete data makes the prediction great challenge. The imbalance between normal and fault samples will reduce the accuracy of the model. In addition, the influence of time-series variables on distribution network is direct and continuous, so the time-series feature extraction is the key technique for fault prediction. In this work, we propose a fault prediction method for distribution network based on CNN and LightGBM algorithm. This method deeply learns feature of time-series data by utilizing CNN, and improves the adaptability for imbalanced dataset by training LightGBM submodels. Experimental results based on fault dataset of a district in Chongqing from 2017 to 2018 show that fault prediction performance can be ameliorated by utilizing this method.

Scientific satellites can effectively detect astronomy. Accurate ground calibration experiments are required on the detector before the satellite payload is completed. Through the X-ray energy spectrum detected by the high-purity germanium detector, the energy resolution and energy response of the energy spectrum can be studied to meet the ground calibration requirements of the gravitational wave electromagnetic counterpart all-weather monitor (GECAM satellite). This paper mainly introduces the performance study of the X-ray high-energy part of the GRD detector, and conducts preliminary calibration experiments on the energy range from 80Kev to 150Kev. The test results: the high-purity enthalpy of the standard detector and the GRD detector have good energy linearity; The energy resolution of the single-energy X-ray of the GRD detector is better than 10.2%@79.9keV, which has good monochromaticity.

Sea clutter is a kind of signal with low signal-to-noise ratio. Fractional Fourier transform is used to gather energy. Fractional Brownian motion model is introduced to model sea clutter. Based on the measured data of IPIX radar, high-order multi-fractal parameters are calculated. Fitting the multi-fractal parameters, choosing the steepest interval and calculating its slope. At the same time, choosing the fractal parameters with scale -30 under HH and VV polarization. The small targets are 0 and 1, respectively. The slope and high-scale fractal parameters of different sea conditions are normalized, and the normalized data are predicted by logistic regression. The simulation results show that FRFT can aggregate the energy of sea clutter signal. Logistic regression model can predict the fractal parameter data of sea clutter FRFT domain, and the prediction accuracy reaches 83.42%.

A circulating cooling water machine using agile bidirectional cooling and heating power control method is developed to produce circulating cooling water of high temperature stability and good dynamic performance. Cooling module based on thermoelectric cooling and multilayer compact structure is proposed to achieve cooling power output resolution at sub-watt level and quick response. Heating module based on a compact solenoid-in-tube structure is proposed to achieve heating power output with sub-watt level resolution and quick response. Experiments indicate that temperature stability of ± 3 mK, regulating resolution of 5 mK and regulating time of 128 s corresponding to 1 K step of circulating cooling water temperature are achieved with the developed machine. Thus, the developed machine can satisfy the challenging requirements of precision manufacturing.

Unmanned Aerial Vehicle (UAV) is widely used in daily life, commercial and military applications, because it is flexible and cheap. But the news of UAV accidents calls people to focus on Prognostics and Health Management (PHM) for UAV, which can predict and detect faults during the UAV ’s flight through the telemetry data. PHM can also help UAV adjust itself to avoid crashes. However, the existing PHM models on UAV have some common problems. The most outstanding one is that they are all suffering from lacking fault data. The amount of fault data is difficult to support PHM modeling. Therefore, establishing a fault injection platform will help in generating fault data and improving the performance of PHM methods. In this work, we propose a platform of fault injection based on ArduPilot. It can simulate different kinds of sensor and actuator faults which may happen on UAV during flight. Through the ground station, we can obtain the telemetry data with faults which can set up a database for PHM modeling. The experiment results show that this method has a good performance for fault injection.
