MDS 1.6.0 examples

Constraint Monitor and correction maneuver workflow

Creates two satellite groups — a chemical-propulsion cluster whose eccentricity and inclination constraints will be violated over time, and a microsatellite electric-propulsion fleet already below its SMA minimum. Demonstrates using the Constraint Monitor UI to detect violations, request a correction, and compute the maneuver via the Maneuver Calculator.

Grafana data generation

Sets up a 6-satellite fleet, propagates a baseline scenario and a maneuver scenario (with continuous thrust applied to two satellites), calculates coverage for both, and streams all results to a Postgres database for side-by-side comparison in Grafana. Optionally integrates Space-track CDM data.

MDS 1.4.0 examples

Constellation Design and Revisit Time calculations

This example demonstrates the capabilities of MDS to aid in designing a constellation. Two constellations are created, for each of them, the global and overlapping ground coverage is computed, as well as revisit times and ground station visit geometry. The results are exported in the Export folder, they are then visualized for both constellations to allow for direct comparison.

example_compute_fleet_coverage.py

Communication, payload and power system integration

Although not utilizing new features, this example demonstrates the capability to integrate power, communications and payload subsystem integration. A mission manager balances between real-time prioritization of data gathering, downlink and maintaining sufficient power.

example_comm_power_manager.py

TLE data generation and ingestion

This script shows the (as of MDS 1.4.0 experimental) TLE generation. Orbit raIsing is executed for two satellites and their resulting TLE's are created.

example_generate_tle.py

Orbital decay

This example shows two satellites' orbits decaying due to the impact of drag. The satellites are configured to have two reference areas exposed to drag, thus they decay at different rates. Once the higher area satellite reached an altitude of 140km, it burns up and is thus removed from the simulation. This can be seen in the altitude history

example_orbital_decay.py

Ground asset modification

Demonstrates how to add different ground assets, control them over time and the flexibility to create/change ground asset locations in intertial frame coordinates.

example_ground_assets.py

Load ISS TLE

Fetches the latest ISS TLE from Celestrak and loads it into MDS to propagate and visualize the ISS orbit.

example_load_iss_tle.py

Toggle satellite labels

Creates a Walker-Delta constellation and demonstrates enabling and disabling satellite name labels in a spacecraft-centred view.

example_toggle_satellite_labels.py

MDS 1.3.0 examples

MDSCamera class interface

Demonstrates the MDSCamera class, which performs automatic dependent parameter solving, calculates the camera intrinsic matrix for projection, and stores camera state for easy per-parameter changes.

example_camera_class_interface.py

Camera depth capture

Demonstrates how to capture raw depth data (float buffer) from a camera attached to a satellite, useful for Vision-Based Navigation scenarios.

Synthetic dataset generation

Generates a labeled image dataset using pre-defined 3D keypoints on a satellite model, projected into camera images with bounding boxes and pose transformation matrices.

example_dataset_generation.py

Satellite Docking simulation

This is a broad example/demonstrator of the ability to perform close-proximity in MDS. A chaser satellite approaches a target, running a GNC loop, docks, transfers fuel and retreats. The prompt at the start of the script also allows to perform a failed docking where the chaser collides with the target.

demo_gnc_docking.py

Thruster plume visualization

This example shows how to connect visual plumes to the thrusters on a satellite 3D model Thrust is then applied in different directions and the effects are visualized.
