ABSTRACT:
A hybrid satellite-based data broadcast system reliably broadcasts data from a ground-based high earth orbit, HEO, server (105) to a plurality of customer provided equipment, CPE, receivers (113) via a HEO satellite constellation satellite (109). When errors in received broadcast data are detected by the CPE (113), error information is communicated via a low earth orbit, LEO, satellite constellation (121, 125) to a LEO gateway (103) which in turn obtains the correct data and transmits the correct data back to the CPE receiver via the LEO satellite constellation (121, 125).
