PDS3 Data Set |
|
Delta-Differential One-way Range Data Record. See page 4 and section 2.1 of the RS EDR Data Product SIS for more information. |
||
|
Compressed Version of TNF - typically to one data point per 10 seconds or one data point per 60 seconds. The ODF contains the most important information (range, Doppler and frequency ramps) needed by the navigation engineers, and investigators interested in determining gravity fields. See page 4 and section 2.1 of the RS EDR Data Product SIS for more information. |
||
|
Radio Science Receiver Record. See page 4 and section 2.1 of the RS EDR Data Product SIS for more information. |
||
|
Tracking and Navigation File (TRK-2-34 data). See page 4 and section 2.1 of the RS EDR Data Product SIS for more information. |

ACK |
An obsolete product containing antenna configuration information. Much of the data in these products are incorrect. The ANT product replaces these. See section 2.2 of the RS EDR Data Product SIS for more information. |
|
|
Antenna Configuration file. Text file containing the antenna configuration based on spacecraft telemetry. See section 2.2 of the RS EDR Data Product SIS for more information. |
||
|
Ionosphere (media) calibration files, providing historical and predicted Earth ionospheric conditions. See section 2.2 of the RS EDR Data Product SIS for more information. |
||
|
Light time files providing the radio propagation time from the spacecraft to the Earth and from the Earth to the spacecraft vs. time. See section 2.2 of the RS EDR Data Product SIS for more information. |
