“…It has been used in numerous missions (e.g., Li et al, 2020), including the first Mars CubeSat mission where two MSP430's coordinated the command and data handling (CDH) system (Schoolcraft et al, 2016). Controllers in this family have also been irradiated, with the MSP430FR5739 microcontroller surviving up to a TID of nearly 250 krad (Netzer et al, 2014).…”

Abstract. The design, characteristics, and performance of a CubeSat magnetometer board (Quad-Mag) equipped with four PNI RM3100 magnetometers is presented. The low size, weight, power, and cost of the RM3100 enables the inclusion of four sensors on a single board, allowing a potential factor of 2 reduction in the noise floor established for an individual sensor via oversampling with multiple sensors. The instrument experimentally achieved a noise floor of 5.34 nT (individual axis), averaging across each axis of the four magnetometers, at a 65 Hz sampling rate. This approaches the theoretically established limit for the system of 4.37 nT at 40 Hz. A single onboard Texas Instrument MSP430 microcontroller handles synchronization of the magnetometers and facilitates data collection through a simple UART-based command interface to a host system. The Quad-Mag system has a mass of 59.05 g and total power consumption of 23 mW while sampling and 14 mW while idle. The Quad-Mag enables nearly 1 nT magnetic field measurements at 1 Hz using commercial off-the-shelf sensors for space applications under optimal conditions.

The low size, weight, power, and cost of the RM3100 enables the inclusion of four sensors on a single board, allowing a potential factor of two reduction in the noise floor established for an individual sensor via oversampling with multiple sensors. The instrument experimentally achieved a noise floor of 5.345 nT (individual axis), averaging across each axis of the four magnetometers, at a 65 Hz sampling rate. This approaches the previously theoretically established limit for the system of 4.37 nT at 40 Hz. A single on-board, Texas Instrument MSP430 microcontroller handles synchronization of the magnetometers and facilitates data collection through a simple UART-based command interface to a host system. The Quad-Mag system has a mass of 59.05 g and total power consumption of 23 mW while sampling and 14 mW while idle. The Quad-Mag enables 1 nT magnetic field measurements at 1 Hz using commercial-off-the-shelf sensors for space applications.

“…The results showed that all microcontrollers failed between 5 and 30 krad due to their flash memory that could no longer be written. On the other hand, the MSP430FR5739 produced by Texas Instruments was tested in [4]. This microcontroller uses ferroelectric random-access memory (FRAM) as opposed to other flash-based models.…”

“…In addition, bipolar operational amplifiers may show ehnanced low dose rate sensitivity (ELDRS) to total dose [8], [9]. However, in [4], this effect was not evidenced with a bipolar operational amplifier equipped with junction field effect transistors (JFET) on its inputs.…”
