Magnetic Field Instruments for the Fast Auroral Snapshot Explorer
The FAST magnetic field investigation incorporates a tri-axial fluxgate magnetometer for DC and low-frequency (ULF) magnetic field measurements, and an orthogonal three-axis searchcoil system for measurement of structures and waves corresponding to ELF and VLF frequencies. One searchcoil sensor is sampled up to 2 MHz to capture the magnetic component of auroral kilometric radiation (AKR). Becau...
متن کاملTowards Fast Safe Mission Planning
I. INTRODUCTION Robotic and cyber-physical systems are proliferating at a breakneck pace. A key technological hurdle is to ensure safety of such systems especially within proximity of humans. While there has been a push in identifying obstacles and unsafe situations via sensors and machine learned predictors [2, 1], the task of embedding such information to determine safe course while obeying r...
متن کاملMission Design of the Dutch-Chinese FAST Micro-Satellite Mission
The paper treats the mission design for the Dutch-Chinese FAST (Formation for Atmospheric Science and Technology demonstration) mission. The space segment of the 2.5 year mission consists out of two formation flying micro-satellites. During the mission, new technologies will be demonstrated and, using spectropolarimeter and altimeter payloads on both spacecraft, observations will be performed c...
متن کاملdesigning a fast locking pll
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
Fast Safe Mission Plans for Autonomous Vehicles
Guaranteeing safety is a key problem that needs to be addressed in order to enable the real-world deployment of robots and autonomous cyber-physical systems (CPS). While there is a lot of interest in deploying sensors and predictors that would identify obstacles and unsafe situations, there is little research on how to use such learned systems to plan and execute missions safely and efficiently...
