Main technical features of Low Energy Charged Particle Sensor (LECPS) are described, taking into account LECPS high sensitivity, wide dynamic range, and conditions of in-flight operation on-board a satellite. LECPS input cascade is capable of current measurement as low as 1 pA within a 120 dB dynamic range, providing error level below 20%. Statistical calculations of acquired data, measuring time considerations and implementation of input cascade auto-calibration technique were applied to gain the best possible stability and accuracy over -20° to +50°C operation temperature.
