ISS Python Wrapper

A Python wrapper for accessing live telemetry data from the International Space Station (ISS) via NASA's Lightstreamer feed.

Installation

pip install lightstreamer-client-lib

Example Usage

Initialize and connect

iss = ISS()

iss.connect()

time.sleep(2) - this is needed toi allow time to connect

• set objects to the node values.

cp = iss.cabin_pressure

ul = iss.urine_tank_qty

print(cp,ul)

Example print statements

print(f"GMT Time: {iss.gmt_time}")

print(f"Cabin Pressure: {iss.cabin_pressure}")

print(f"Cabin Temperature: {iss.cabin_temperature}")

print(f"Solar Beta Angle: {iss.solar_beta_angle}")

print(f"CMGs Online: {iss.cmgs_online_count}")

print(f"CMG 1 Status: {iss.cmg_1_online}")

print(f"Attitude Roll Error: {iss.attitude_roll_error}")

print(f"X Position: {iss.state_vector_x_pos} meters")

print(f"Y Position: {iss.state_vector_y_pos} meters")

print(f"Z Position: {iss.state_vector_z_pos} meters")

print(f"Lab O2 Pressure: {iss.lab_ppo2}")

print(f"Lab N2 Pressure: {iss.lab_ppn2}")

print(f"Lab CO2 Pressure: {iss.lab_ppco2}")

Notes

• All properties return Optional types - they may return None if data is not available
• Status properties return human-readable strings (e.g., "OPEN", "CLOSED") instead of numeric codes
• The wrapper automatically connects to NASA's live telemetry stream
• Data updates in real-time as the ISS transmits new telemetry
