This paper presents our latest research in the field of microsatellite sensor network design. In the experiment we've designed the overall structure of system including module layout and circuit design, node application software platform by utilizing system-on-chip CC2530 chip as the hardware development platform. The system uses network communication protocol-stack to set up the system. The system test has yielded good results, showing high receiver sensitivity, ideal communication distance, low latency network communication, high data transmission efficiency and strong network robustness.

“…It is a low-power, low-mass device designed for use on microsatellites, weighing in at only 34 grams. A linear pixel array is used to capture an image, which is then processed by an integrated microcontroller to output floating point sun vector measurements in the sensor frame (Enright and Sinclair, 2007). Since the processing is done onboard by the sensor, producing sun vector measurements is of minimal computational cost to the rover computer.…”

“…The measuring range of the system is ±0.5 mm, and measuring precision is ±0.001 mm. In this paper, we select the one-dimensional PSD, that its light receiving area is 81 mm 2 , nonlinear RMS is less than 0.15 %, and typical position error is ±5 μm, as the photoelectric displacement detection device, which produced by the Hamamatsu company. …”

“…The satellite gets the sun vector location information, in the satellite body coordinate system by the sun sensor, to measure, confirm and control the satellite's attitude [1][2][3][4][5]. From the sun sensor, the satellite can also get satellite spin rate and phase information in the spin of the satellite.…”

Abstract. According to the requirement of small satellite, this paper designed a digital sun sensor which diaphragm is a V-shaped cross-section structure. Using Position Sensitive Detector (PSD) as the light detector, we designed the V-shaped cross-section structure based on the pinhole imaging principle. The sun sensor realized the accurate calculation for two axis sun angle of the sun sensor. The mechanical test, thermal test and testing of the sun sensor are designed and carried out. The mechanical test and thermal test results verify the stability of the sun sensor. Testing result shows that the detection angle can reach (120°)×(120°), and the attitude determination accuracy is better than 6" in the entire viewing field. The mass, volume and power consumption of the sun sensor is 0.177 kg, 78 mm×77 mm×21 mm and 0.25 W. The sun sensor has low power consumption, large viewing angle and high precision characteristics, which realized the sun sensor the miniaturization and meet the requirements of the micro satellite. Its performance has been verified in orbit.
