Summary

The SkyFox Labs piDOSE-DCD is a digital CubeSat dosimeter designed to provide the information about local gamma ray radiation background aboard small satellites in space, based on ten seconds and minute period measurements, without the use of high voltage geiger-tube sensors.

The PIN diode solid state radiation sensor is equipped with scintillation crystal to extend the lateral sensitive volume to almost omnidirectional and wider energy range (~0.2 - 10 MeV).

The unit contains electrical outputs to signalize the Alarm threshold reached (similar to two times the ISS average dose rate), ERROR signal in case of sensor overload (overdose), INTERRUPT signal to signalize UART data packet transfer, Digital Counts Per Minute pulse output with equalized pulse width and Analog Counts Per Minute Output from the analog comparator.

There are six packets sent about counts per 10 second period, followed by a summary packet indicating doserate integrated over past 60 seconds added with telemetry information (voltage, temperature, uptime).
