  Observations from space missions have allowed significant progress in many
scientific domains due to the absence of atmospheric noise contributions and
having uninterrupted data sets. In the context of asteroseismology, this has
been extremely beneficial because many oscillation frequencies with small
amplitudes, not observable from the ground, can be detected. One example of
this success is the large number of hybrid delta Sct-gamma Dor stars
discovered. These stars have radial and non-radial p- and g-modes
simultaneously excited to an observable level allowing us to probe both the
external and near-to-core layers of the star. We analyse the light curve of
hybrid delta Sct-gamma Dor star CoRoT ID 102314644 and characterise its
frequency spectrum. We detected 29 gamma Dor type frequencies in the range
[0.32-3.66] cycles per day (c/d) and a series of 6 equidistant periods with a
mean period spacing of DeltaPi=1612 s. In the delta Sct domain we found 38
frequencies in the range 8.63-24.73 c/d and a quintuplet centred on the
frequency p_1=11.39 c/d and derived a possible rotational period of 3.06 d. The
frequency analysis of this object suggests the presence of spots at the stellar
surface, nevertheless we could not dismiss the possibility of a binary system.
The initial modelling of the frequency data along with external constraints has
allowed us to refine its astrophysical parameters giving a mass of
approximately 1.75 solar masses, a radius of 2.48 solar radii and an age of
1241 Myr. The observed period spacing, a p-mode quintuplet, the possible
rotation period and the analysis of the individual frequencies provide
important input constraints for the understanding of different transport
phenomena in A-F-type stars.[abridged]
