During the "Burst mode", high-precision data were collected above the specific areas of interest, corresponding mostly to the seismic regions. The data bit rate in this mode was 1.7 Mbit/s.

During the "Survey mode", averaged data were collected all around the Earth. The telemetry flow in this mode was reduced by the on-board data processing to 25 kbit/s.
