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.

In this paper, we present an approach to represent underlying errors in measurements and physical models in the temporal gravity field determination using GRACE observations. This study provides an opportunity to improve the error model and the accuracy of the GRACE parameter estimation, as well as its successor, GRACE Follow-On.

We present the design considerations, and deployment of an autonomous modular terrestrial rover for ice-sheet exploration that is inexpensive, easy to construct, and allows for instrumentation customization. The rover proved capable of driving over 20km on a single charge with a drawbar pull of 250N, sufficient to tow commercial ground-penetrating radars. Due to its low cost, low-power requirements, and simple modular design, mass deployments of this rover design are practicable.
