Sažetak
We present the first detailed reduction of a double-station meteor recorded solely by a low-cost Raspberry Pi-based meteor system and demonstrate the quality of the data. The reduced event was a Daytime Arietid with an entry angle of only about 1 degree and it lasted for 2.5 s. It had a sun-skirting orbit and it reached an equilibrium temperature of over 1000 K at perihelion. Due to the low entry angle the dynamic pressure on the meteor slowly increased and the compressive strength could be precisely measured. The meteoroid fragmented into a long trail at around 1.3 kPa, a very low compressive strength which indicates a highly porous meteoroid which had its volatiles completely removed due to a high level of thermal processing.
