LIDAR is a distance and speed measurement device using reflection characteristics of emitted light. Space industry is using LIDAR to scan planet surfaces before landing missions, to measure distances between spacecraft and for many other applications. Having the most sensitive detector is critical to measure long distances, particularly in space applications. First LIDAR-dedicated silicon...
To date most of the front-end implementations for spaceborne fluxgate magnetometers are built using a mix of discrete components and multiple integrated circuits. The MFA-3 (Magnetometer front-end ASIC) initiated a first step towards miniaturization, integrating parts of the whole front-end electronics on a single chip. This ASIC is based on an outdated process technology and offers a small...
We present APOCAT, an integrated circuit (IC) for reading out spaceborne photon detectors, i.e., photomultiplier tubes (PMTs) and silicon photomultipliers (SiPMs). The circuit can be used in x-ray and gamma-ray detectors, for example, the advanced space-based solar observatory ASO-S. ASO-S shall be launched in 2022 to study solar flares and coronal mass ejections on the Sun. APOCAT is related...
This paper describes a new kind of volage clamp IC combining precise regulation with high current capability and it's various application use cases. Special attention is given to thermal design limitations.
The evolution of power distribution in spacecraft goes into direction of modular architecture. Especially the secondary power distribution from the satellite bus to the local consumers...
ABSTRACT
This presentation describes the mixed-signal microcontrollers GR716A and GR716B. These microcontrollers target embedded control applications with hard real-time requirements. The GR716A is currently available at prototype level. Extended electrical and radiation characterization is on-going as part of the activity Microcontroller for embedded space applications, initiated and...
This paper describes a small-size and easy to use hybrid DC/DC converter controller with integrated switch. It integrates in one component all the complex functionality required for low power isolated DC/DC converters in space applications, allowing a reduction of size, cost, and design effort.
In a satellite there are tens of low power isolated DC/DC converters that generate the voltage...
INTRODUCTION
Traditionally, Rad-Hard Permanent Magnet Synchronous Motor (PMSM)/ Brushless DC (BLDC) motor control uses the Field Oriented Control (FOC) method and is implemented using a Field Programmable Grid Array (FPGA) for the digital control portion and the drive and sense power/analog circuits are built using available Rad-Hard discrete or simple integrated circuits. This yields a...
When exposed to radiation, semiconductor components exhibit various single-event effect (SEE) and total ionization dose (TID) behavior. Notably, parametric drifts, latch-up and ?functional disruptions? (SEL and SEFI, resp.). These effects have been studied and dealt with in the industry for several decades.
The obvious approach for operating in the space environment, namely the use of...
This work presents the status of the TM/TC MS-ASIC development (telemetry and telecommand mixed-signal application specific integrated circuit) and describes its final implemented features and target applications.
TM/TC MS-ASIC integrates in a single chip solution the functionality of many electrical and electronic components used on spacecraft subsystems. Its main goal is to replace these...
