  Aims. The knowledge of the orbits and origins derived from meteors is
important for the study of meteoroids and of the early solar system. With an
increase in nano-satellite projects dedicated to Earth observations or directly
to meteor observations (e.g., the Meteorix CubeSat), we investigate the
stereoscopic measurement of meteor positions using a pair of cameras, one
deployed in space and one on the ground, and aim to understand the accuracy and
the main driving factors. This study will reveal the requirements for system
setups and the geometry favorable for meteor triangulation. Methods. This
Letter presents the principle of the stereoscopic measurement from space and
the ground, and an error analysis. Specifically, the impacts of the resolutions
of the cameras, the attitude and orbit determination accuracy of the satellite,
and the geometry formed by the moving target and observers are investigated.
Results. To reach a desirable positioning accuracy of 1 km it is necessary to
equip the satellite with high-accuracy sensors (e.g., star tracker and GPS
receiver) to perform fine attitude and orbit determination. The best accuracy
can occur when the target is at an elevation of 30 deg. with respect to the
ground station.
