The orbital elements together with their probable errors for 454 faint meteors spanning the range 0.5 to 8.5 in absolute magnitude are presented. The observations were made with two very sensitive television systems between May 1981 and August 1982. Both the cometary and asteroidal groups of meteors discovered in photographic meteor surveys are also present in the TV data but the cometary group with randomly inclined orbits appears to be more diffuse than for the photographic meteors. Many TV meteors have retrograde orbits with aphelia > 3 A.U. and also a greater proportion of orbits have very small perihelia when compared with the Super-Schmidt meteors. These features seem to suggest that the meteoroid population is in a state of dynamic equilibrium with a source of TV meteoroids replenishing those lost by Jovian perturbations and solar heating.
