I/O interface and utilities for CCSDS binary spacecraft data in Python. Library used in flight missions at NASA, NOAA, and SWRI

CCSDSPy - IO Interface for Reading CCSDS Data in Python.

This package provides a Python interface for reading tightly packed bits in the Consultative Committee for Space Data Systems (CCSDS) format used by many NASA and ESA missions.

Installation

To install ccsdspy

pip install ccsdspy

Usage Example

The following example shows how simple it is to read in fixed length CCSDS packets.

import ccsdspy
from ccsdspy import PacketField, PacketArray

pkt = ccsdspy.FixedLength([
     PacketField(name='SHCOARSE', data_type='uint', bit_length=32),
     PacketField(name='SHFINE',   data_type='uint', bit_length=20),
     PacketField(name='OPMODE',   data_type='uint', bit_length=3),
     PacketField(name='SPACER',   data_type='fill', bit_length=1),
     PacketField(name='VOLTAGE',  data_type='int',  bit_length=8),
     PacketArray(
         name='SENSOR_GRID',
         data_type='uint',
         bit_length=16,
         array_shape=(32, 32),
         array_order='C'
     ),
])

result = pkt.load('mypackets.bin')
