The myBUTTERFLY is a portable device used to provide real-time measurements of NO2 pollutant concentrations in the air. The measured pollutant concentrations and location of the measurement are wirelessly sent by the device via Bluetooth or GSM, according to device configuration. The data is collected for post-processing analysis and further informative use in the Cloud.
The device is using sensors from SpecSensors 3SP-NO2-5F. The sensitive electronics is shielded from external interference. The device has been designed as an affordable mobile platform serving a singular purpose of local real-time NO2 pollutant monitoring. The device can be integrated into a wider measuring network via wireless connection with a mobile phone (both Android and iOS devices are supported) or as a fully independent unit.

The instrument 2SD [tu:esdi:] (Space Dosimetry System Demonstrator) is composed of two detectors:
- SXRM (SpacepiX Radiation Monitor)
- SXM (Soft X-ray Monitor)
The SXRM is a radiation monitor based on the revolutionary SpacePix2 ASIC. It can be used for a wide range of space radiation monitoring applications and was developed in cooperation between esc Aerospace and FNSPE CTU (Czech Technical University) in Prague. It is designed for long-term orbital missions of up to 15 years on GEO, MEO, LEO and interplanetary missions. It has been developed to be compliant with European Space Agency (ESA) requirements for radiation hardness and has been fully ESA qualified. The device is designed as a space environment awareness monitor for communication, navigation and Earth observation satellites. It will monitor the space weather radiation component. SXRM is sensitive to electrons and protons from the van Allen belt and heavy ions from the galactic cosmic rays. It detects individual particles and was designed to operate even in a dynamic range of solar particle events with fluxes of up to 106 protons cm2s-1. The SXRM uses pattern recognition techniques in 5 detection layers, interleaved with energy absorbers in a telescopic configuration, to cover a large particle energy range.
The SXM detector is designed for the measurement of the flux and spectrum of soft X-rays photons, emitted during transient events in the Solar magnetosphere, such as X-ray flares during magnetic reconnection. The SXM uses the specialized X-CHIP-03-SXR ASIC with a dynamic range optimized for soft X-ray photon measurement.
The SpacePix2 detection chip is a radiation-resistant monolithic pixel ionizing radiation detector developed at the FNSPE CTU in 180 nm SoI CMOS process for space dosimetry and charged particle detection. SpacePix2 measures approximately 4×5.5 mm2 and contains 4096 pixels arranged in a matrix of 64×64 pixels. The dynamic range is extended using a technique of backside pulse digitization and has a range of five orders of magnitude, making it capable to characterize particles from low-energy electrons to high-energy heavy ions of galactic cosmic rays. Its small dimensions, low power consumption, simple interfacing and large dynamic make it ideal for mass deployment in space situation awareness applications.
The 2SD instrument is based on the second generation esc Aerospace on-board computer and data processing board escOBC2™, and includes an additional interface and power board for the detectors. The escOBC2™ is an upgraded version of the escOBC™. The board is featuring a state-of-the-art 32-bit processor based on 45nm technology and 0.5 MB of radiation immune MRAM memory for critical system data and 128 MB of flash mass storage for mission or scientific data. The product is compatible with the standard Cubesat PC104 form factor and features a main connector compatible with most of the Cubesat boards. The Communication with subsystems can be established via UART, CAN, SPI, I2C or discrete lines. For safety reasons the escOBC2™ is equipped with an independent HW watchdog to prevent system hangs and current&voltage monitors.
The solar radiation is detected using the pixel chip XChip03SXR. The insight of each sensor is shielded by a thin titanium foil to protect against photons and low-energy particles.

Dear partners, we will be at Industry Space Days 2020 organized by European Space Agency! This event will take place online for the first time on 16 – 17 September 2020. It enables an opportunity to meet wider, please join us there! https://isd.esa.int/event/
London Gatwick Airport reports another incidence with a drone writes Michael Wieland, UAV DACH’s manning director in his latest LinkIn post. Threats like this one have caused total airport shut downs in the past, along financial losses in the multi-million Euro range. Not to mention the threat to passengers.
esc Aerospace provides solutions to detect, track and mitigate rogue drones as Dr. Andreas Hausotter explains in a recent article in the Frankfurter Allgemeine Zeitung FAZ. Our offer includes consultation and concept development. Every solution is tailored to our customer needs. Contact us for information!
A team of Czech academia and industry has developed new SpacePix Detectors® for cosmic weather studies. On Friday July 5th, 2019 a set of detectors will be launched board the Russian satellite Socrat-R. The primary mission is to monitor the cosmic weather and the Earth’s radiation field. SpacePix uses unique monolithic pixel detectors developed by the Czech Technical University (CTU, Faculty of Nuclear and Physical Engineering), supplemented with PIN diode open-source Dosimeter developed at the Institute of Nuclear Physics ASCR.
The Czech part of the satellite apparatus was designed by the consortium of FJFI CTU, esc Aerospace s.r.o. and ÚJF AVČR. Prime contractor for design and production of the whole instrument was esc Aerospace s.r.o. with major contributions of FJFI CTU in Prague, ÚJF and Universal Scientific Technologies s.r.o. The radiation-resistant new generation detectors were developed in the Czech Republic at FJFI in the framework of the TA ČR and the MPO grants. These projects are a spin-off project of the CZECH Competence Centre TE01020069. The PIN-diode dosimeter was developed as part of the CRREAT project.
Launch of the Soyuz 2.1 b/Fregat carrier can be watched online on Friday July 5th at 7:41 PM CET: https://lnkd.in/dXwyDBq
