DSN60ByteObservationFile Object

Description

The DSN60ByteObservationFile object provides functionality for reading DSN data (range and range rate) from DSN 60-Byte Observation files. This is a GSFC internal 60-byte binary format. Each file of DSN 60-byte tracking data contains one or more header records and an associated batch of data records accompanying each header record – the header record containing information necessary for the accurate conversion of the raw data contained in the data records. The time system is UTC, and the range and range-rate data is reference frame independent.

Timing Precision Mode

This page describes functionality in millisecond timing precision mode. Millisecond timing precision mode is deprecated and will be removed in a future release. We recommend that you migrate your Mission Plans to nanosecond timing precision mode.
