The spatial and temporal performance of a telescope system comprising planar silicon sensors bump-bonded to Timepix4-v2 ASICs are assessed at the CERN SPS using a 180~GeV/c mixed hadron beam. The pointing resolution at the centre of the telescope is 2.3±0.1μm and 2.4±0.1μm in x and y directions, respectively. The temporal resolution for the combined timestamps on a track using only the information from the Timepix4 planes is found to be 92±5~ps. The telescope is extensively described including its data acquisition system and dedicated software as well as the corrections applied to the raw measurements.
