Mars Pathfinder Ranging Data

These represent a round-trip light time for each range measurement by the NASA Deep Space Network to the Mars Pathfinder lander. A calibration for the tropospheric and ionospheric path delay at the DSN stations has been applied based on calibration data specific to the time of each measurement. No calibration or model for solar plasma has been applied. The measurements are all at X-band, with Earth-to-spacecraft signals sent at ~7.2GHz, and spacecraft-to-Earth signals sent at ~8.4 GHz. The spacecraft transponder delay of ~420 has NOT been removed from these measurements, so should be applied or estimated by the user. The table columns are; Column 1 is a spacecraft identifier (1 for VL1, 2 for VL2, 3 for MPF, 4 for MGS, 5 for ODY, 6 for MRO) Column 2 is the DSN transmitting station ID Column 3 is the DSN receiving station ID Column 4-6 are the UTC date at station reception Column 7 is the UTC time at station reception Column 8 is the adjusted round-trip light time in microseconds from the DSN station to the lander and back Column 9 is the estimated measurement accuracy in microseconds 3 15 15 1997 JUL 6 03:32:03 1287957826.329 .067 3 15 15 1997 JUL 6 03:45:34 1288025662.239 .067 3 65 65 1997 JUL 22 15:31:50 1400147816.478 .067 3 65 65 1997 JUL 25 18:03:31 1420414209.718 .067 3 65 65 1997 JUL 25 18:17:02 1420476556.473 .067 3 65 65 1997 JUL 25 18:30:33 1420539021.078 .067 3 65 65 1997 AUG 28 13:37:06 1622375089.657 .069 3 65 65 1997 AUG 28 13:48:13 1622416889.138 .069 3 65 65 1997 AUG 28 13:59:20 1622458776.322 .069 3 65 65 1997 AUG 28 14:10:27 1622500751.997 .068 3 65 65 1997 AUG 28 14:21:34 1622542816.635 .068 3 65 65 1997 AUG 28 14:32:41 1622584970.636 .068 3 65 65 1997 AUG 28 14:43:48 1622627214.073 .068 3 65 65 1997 AUG 29 13:49:17 1627866640.961 .069 3 65 65 1997 AUG 29 13:55:40 1627890488.777 .137 3 65 65 1997 AUG 29 14:02:03 1627914367.343 .137 3 65 65 1997 AUG 29 14:08:26 1627938276.859 .137 3 65 65 1997 AUG 29 14:14:49 1627962217.483 .137 3 65 65 1997 AUG 29 14:21:12 1627986189.363 .136 3 65 65 1997 AUG 29 14:27:35 1628010192.596 .136 3 65 65 1997 AUG 29 14:33:58 1628034227.200 .136 3 65 65 1997 AUG 29 14:40:21 1628058293.295 .136 3 65 65 1997 AUG 30 13:26:00 1633197277.391 .140 3 65 65 1997 AUG 30 13:32:23 1633220801.954 .139 3 65 65 1997 AUG 30 13:38:46 1633244357.613 .138 3 65 65 1997 AUG 30 13:45:09 1633267944.671 .138 3 65 65 1997 AUG 30 13:51:32 1633291563.497 .138 3 65 65 1997 AUG 30 13:57:55 1633315214.140 .137 3 65 65 1997 AUG 30 14:04:18 1633338897.090 .137 3 65 65 1997 SEP 1 14:40:42 1644216379.326 .136 3 65 65 1997 SEP 1 14:47:05 1644239861.449 .136 3 65 65 1997 SEP 1 14:53:28 1644263379.295 .136 3 65 65 1997 SEP 1 14:59:51 1644286932.965 .136 3 65 65 1997 SEP 1 15:06:14 1644310522.584 .136 3 65 65 1997 SEP 1 15:12:37 1644334148.178 .135 3 65 65 1997 SEP 1 15:19:00 1644357809.898 .135 3 65 65 1997 SEP 3 18:04:51 1655595256.805 .136 3 65 65 1997 SEP 3 18:11:14 1655619451.126 .136 3 65 65 1997 SEP 3 18:17:37 1655643676.209 .136 3 65 65 1997 SEP 3 18:24:00 1655667931.336 .137 3 65 65 1997 SEP 3 18:30:23 1655692215.981 .137 3 65 65 1997 SEP 3 18:36:46 1655716529.392 .137 3 65 65 1997 SEP 4 17:51:12 1660804477.266 .136 3 65 65 1997 SEP 4 17:57:35 1660828401.153 .136 3 65 65 1997 SEP 4 18:03:58 1660852358.573 .136 3 65 65 1997 SEP 4 18:10:21 1660876349.074 .136 3 65 65 1997 SEP 4 18:16:44 1660900372.055 .137 3 65 65 1997 SEP 4 18:23:07 1660924426.915 .137 3 65 65 1997 SEP 4 18:29:30 1660948513.099 .137 3 65 65 1997 SEP 4 18:35:53 1660972629.930 .137 3 65 65 1997 SEP 4 18:42:16 1660996776.772 .137 3 65 65 1997 SEP 4 18:48:39 1661020952.976 .138 3 65 65 1997 SEP 4 18:55:02 1661045157.841 .138 3 65 65 1997 SEP 4 19:01:25 1661069390.634 .139 3 65 65 1997 SEP 4 19:07:48 1661093650.625 .139 3 65 65 1997 SEP 4 19:14:11 1661117937.020 .140 3 65 65 1997 SEP 6 19:02:50 1671502314.901 .139 3 65 65 1997 SEP 6 19:09:13 1671526179.150 .140 3 65 65 1997 SEP 6 19:15:36 1671550072.930 .140 3 65 65 1997 SEP 6 19:21:59 1671573995.520 .141 3 65 65 1997 SEP 6 19:28:22 1671597946.221 .142 3 65 65 1997 SEP 6 19:34:45 1671621924.306 .143 3 65 65 1997 SEP 6 19:41:08 1671645929.024 .145 3 65 65 1997 SEP 6 19:47:31 1671669959.535 .147 3 65 65 1997 SEP 7 18:36:40 1676574760.981 .138 3 65 65 1997 SEP 7 18:43:03 1676598278.860 .138 3 65 65 1997 SEP 7 18:49:26 1676621829.701 .138 3 65 65 1997 SEP 7 18:55:49 1676645412.980 .139 3 65 65 1997 SEP 7 19:02:12 1676669028.156 .139 3 65 65 1997 SEP 7 19:08:35 1676692674.603 .140 3 65 65 1997 SEP 7 19:14:58 1676716351.759 .141 3 65 65 1997 SEP 7 19:21:21 1676740058.950 .141 3 34 34 1997 SEP 22 02:52:26 1747577487.662 .133 3 34 34 1997 SEP 22 02:58:49 1747597980.560 .133 3 34 34 1997 SEP 22 03:05:12 1747618507.154 .133 3 34 34 1997 SEP 22 03:11:35 1747639067.905 .133 3 34 34 1997 SEP 22 03:17:58 1747659663.255 .133 3 34 34 1997 SEP 22 03:24:21 1747680293.575 .133 3 34 34 1997 SEP 22 03:30:44 1747700959.242 .133 3 34 34 1997 SEP 25 04:32:04 1762066075.012 .133 3 34 34 1997 SEP 25 04:38:27 1762086531.075 .133 3 34 34 1997 SEP 25 04:44:50 1762107026.200 .133 3 34 34 1997 SEP 25 04:51:13 1762127560.607 .133 3 34 34 1997 SEP 25 04:57:36 1762148134.380 .133 3 34 34 1997 SEP 25 05:03:59 1762168747.811 .133 3 34 34 1997 SEP 25 05:10:22 1762189400.900 .133 3 34 34 1997 SEP 25 05:16:45 1762210093.781 .133 3 34 34 1997 SEP 25 05:23:08 1762230826.514 .133 3 34 34 1997 SEP 25 05:29:31 1762251599.112 .133 3 34 34 1997 SEP 25 05:35:54 1762272411.593 .133
