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.
To install ccsdspy
pip install ccsdspy
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')
