Abstract: In this work, we report the in-orbit demonstration of X-ray pulsar navigation with Insight-Hard X-ray Modulation Telescope (Insight-HXMT) Satellite, which was launched on 2017 June 15. The new pulsar navigation method Significance Enhancement of Pulse-profile with Orbit-dynamics is adopted to determine the orbit with observations of only one pulsar. In this test, the Crab pulsar is chosen and observed by Insight-HXMT from 2017 August 31 to September 5. Using the five-day long observation data, the orbit of Insight-HXMT is determined successfully with the three telescopes onboard: High Energy X-ray Telescope, Medium Energy X-ray Telescope, and Low Energy X-ray Telescope, respectively. By combining all the data, the position and velocity of the Insight-HXMT are pinpointed to within 10 km (3ҩ and 10 m s

Semi-physical simulation of attitude control system is the more synthetically test and verify for designing of small satellite control system. It is an important means of small satellite development. However
the results of current semi-physical simulation system have a lot of non-intuitive. Compare with the actual environment
the simulation environment still has striking disparity. So the shortcomings affect precision of simulation. Based on the virtual display technology
the group semi-physical simulation system has been constructed for attitude control of small satellite due to the combination with xPC real-time environment
the simulation computer
high-precision single-axis air-bearing turntable
reaction wheel
air thrust device
fiber gyroscopes
sensors synchronizer
power subsystem and wireless devices virtual display computer etc. Semi-physical simulation achieved the visual simulation in orbit and tracked new information of virtual environment of space into real-time simulation computer. Simulation results show that the simulation system for real-time attitude and orbit position of small satellite semi-physical simulation has an excellent display effect. At the same time
Real-time transfuse of orbit information provides a more accurate space environment simulation. The simulation system of small satellite attitude control to design and evaluate the more direct and convenient. (2012) Trans Tech Publications

For the factors of increased of tasks
enhancements of functions and improvement of integrity and complexity in aerospace camera
application system has raised high and long-term in-orbit autonomy and reliability requirements on camera controller. Based on an actual project application background
this paper has put forward a design method of new high reliability aerospace camera controller in-orbit software reinjection instruction sequence which use TSC695F as kernel CPU and process flow of bootstrap receive
cache
checkout and storage update data. Finally
combined with specific test module for camera controller software re-injection
the validity of the software re-injection method raised here has been verified. Still here gives out reference codes of update data package which generated by the ground. 2012 IEEE.

The design of ultraviolet ozone vertical profile probe is illustrated and the electronic system is introduced in detail. The device is a compact
high precision
ultraviolet-vacuum
ultraviolet spectral radiometer
and is used to measure atmospheric solar backscattering spectral radiance and solar spectral irradiance. Noise of the system is analyzed and Numeric accumulation and synchronous demodulation was used to decrease the noise and the zero-drift of the instrument. The solar irradiance at altitude 830 km in 160-400 nm and the backscattering solar spectral radiance in the ultraviolet ozone absorption band at 12 wavelengths from 250 nm to 340 nm are obtained. Test results on orbit show that all the requested function is met successfully and the performance is stable. 2011 IEEE.

In order to eliminate the influence of aircraft attitude angle to the image quality of space camera
and assure that the drift angle of space camera could be accurately adjusted at the orbit
a novel closed-loop test method is provided for real-time drift angle adjustment of space camera on the Earth. A long focal length dynamic aim generator is applied to simulate the image motion and the variety drift angle
and to detect the precision of the image motion compensation machinery and the capability of the drift angle control system. The computer system is used to control the dynamic aim generator
accomplish the data processing
transmit and receive the data information. The seamless connection and the data transmission between the aim generator and the aircraft simulation devices are constituted. The command
parameter and drift angle data transmitted by the simulation devices are received by the space camera at the real time
then the photos are taken and the draft angle is adjusted simultaneously. It is shown that the drift angle can be accurately tracked by the space camera at the real time
and the detective method satisfies the test requirement. 2010 Copyright SPIE - The International Society for Optical Engineering.
