A software application for streamlining investigations of the Martian atmosphere is described. The main components are a 1D model of the Martian atmosphere, observations of the Martian atmosphere and a software wrapper. We verify our model using the application. The model and observations agree except over the winter solstice where mechanical heating of the atmosphere, from downward flowing air, is likely warming the atmosphere. We update our model to include this effect.

Measurements from the magnetic field instrument on the Cassiope spacecraft were found to be degraded by an artifact of how the instrument tracks the changing magnetic field as the spacecraft orbits the Earth. We present a process to characterize this effect on-orbit and compensate for it in the post processing of the data. This work allows the instrument to accurately track rapidly changing local fields without loss of measurement fidelity and improves the high-frequency noise of the data.

Towards the complex observation requirements of Fengyun-4 (FY-4) satellite, the new generation of geostationary meteorological satellite of China, instrument observation strategies are proposed, on which the instruments' in orbit daily observations must be based. The strategies have been successfully used in FY-4A in-orbit test for more than a year. Both the simulation results and in-orbit application results are given to demonstrate the validity of the strategies.

Daedalus targets to measure the largely unexplored area between Earth's atmosphere and space. Here, intriguing and complex processes govern the deposition, transformation and transport of energy. The aim is to quantify this energy by measuring, for example, effects caused by electrodynamic processes in this region. The concept is based on a mother satellite which carries a suite of instruments along with smaller satellites carrying a subset of instruments that are released into the atmosphere.

The CUGB-CS48DAS data acquisition system was designed for seismic purpose at first. However, we tried to integrate the acquisition circuit and after several hardware improvements and software updates, it can be used now for seismic exploration as well as electrical prospecting. It has good application effects in engineering geology, mineral geology and energy geology, and is suitable for exploration tasks in coalfields, petroleum, minerals, earthquake monitoring and urban construction, etc.

Measuring the magnetic field on-board spacecraft requires regular in-flight calibrations activities. Among those, determining of the output of magnetometers under vanishing ambient magnetic fields, the so-called magnetometer offsets, is essential. Typically, characteristic rotations in solar wind magnetic fields are used to obtain these offsets. This paper addresses the question of how much solar wind data are needed to reach certain accuracy levels in offset determination.
