Meteoroids entering the Earth's atmosphere can be observed as meteors,thereby providing useful information on their formation and hence on theirparent bodies. We developed a data reduction software package for doublestation meteor data from the SPOSH camera, which includes event detection,image geometric and radiometric calibration, radiant and speed estimates,trajectory and orbit determination, and meteor light curve recovery. Thesoftware package is designed to fully utilise the high photometric quality ofSPOSH images. This will facilitate the detection of meteor streams and studiesof their trajectories. We have run simulations to assess the performance of thesoftware by estimating the radiants, speeds, and magnitudes of syntheticmeteors and comparing them with the a priori values. The estimateduncertainties in radiant location had a zero mean with a median deviationbetween 0.03$^{\circ}$ and 0.11$^{\circ}$ for the right ascension and0.02$^{\circ}$ and 0.07$^{\circ}$ for the declination. The estimateduncertainties for the speeds had a median deviation between 0.40 and 0.45 kms$^{-1}$. The brightness of synthetic meteors was estimated to within +0.01m.We have applied the software package to 177 real meteors acquired by the SPOSHcamera. The median propagated uncertainties in geocentric right ascension anddeclination were found to be of 0.64$^{\circ}$ and 0.29$^{\circ}$, while themedian propagated error in geocentric speed was 1.21 km $s^{-1}$.
