AstroLink SEP satellite mission analysis workspace with live 3D Earth and ground-track views
AstroLink Spacecraft Engineering Platform (SEP) with 3D and ground-track views in the mission workspace.

01

Configurable mission views

Arrange one to four 3D, ground-track, telemetry or graph tiles using layouts built for the task at hand.

02

One shared context

Selection, camera targets, mission time and engine state stay synchronized across every active view.

03

Objects without busywork

Create satellites, Walker and elliptical constellations, ground sites and sensors, or import TLEs in batches.

Propagation

Model the orbit you intend to fly.

Edit a satellite in Keplerian or Cartesian form, choose the scenario-wide fidelity, and see the current state reconcile with the live engine.

The current SEP Orbit page with sample mission inputs, scenario-wide force settings and explicit space-weather data coverage.

01

Editable orbital state

Validated orbital elements, Cartesian state, mass and geometry remain accessible from one object page.

02

High-precision force stack

Select Earth zonal gravity through degree 70, JB2008 atmospheric drag and Sun/Moon DE440 perturbations.

03

A live Rust engine

Commands, snapshots and propagation run through the same memory-safe native core used by SEP.

Satellite access and ground-station analysis

Access & Ground Station (AGS)

Connect the spacecraft to the ground segment. SEP brings ground-station modeling and station-to-satellite access analysis into the mission workspace, so your team can examine where and when a station can see a satellite.

01

Ground-station modeling

Define ground-station locations and antenna configurations alongside your satellites and constellations.

02

Access windows and constraints

Configure line-of-sight, elevation, range and illumination constraints, then inspect access windows, timelines and current-time visibility.

03

Results your team can review

Inspect access results with their status and diagnostics, and export CSV outputs for engineering review.

AGS is part of SEP’s current testing programme. Discuss your station network, mission interval and analysis requirements with the AstroLink team.

Analysis and output

Understand more than position.

Follow the physical consequences of the trajectory with spacecraft power, eclipse context, live telemetry and reusable outputs.

Computed eclipse events and generated-power samples from a configured satellite in SEP’s Power page.

01

Six-face spacecraft power

Define the spacecraft power geometry and inspect live illumination and generated power per satellite.

02

Eclipse-aware mission time

DE440 solar geometry drives power verification and retained penumbra and umbra events on the shared timeline.

03

Telemetry, graphs and reports

Move from virtualized live data to reusable graph and report workflows without exporting to another tool first.

For the space sector

Mission analysis tools for engineers, space companies and new ventures.

SEP supports conversations across the space sector, from satellite mission engineers and operators to startups, established space companies, research teams and investors assessing space ventures.

01

Satellite mission engineers and operators

Keep satellites, constellations, timelines, telemetry and analysis views synchronized in one mission context.

02

Space companies and industry ventures

Evaluate mission concepts and system behavior with a native workspace backed by a high-fidelity propagation core.

03

Universities and research teams

Explore orbital mechanics, spacecraft power, eclipse events and constellation behavior through inspectable models and visual results.

04

Resilient navigation teams

Build on the same physics foundation behind AstroLink’s Doppler-only GNSS-denied navigation research.

05

Space startups

Discuss the orbit, constellation and spacecraft analyses your mission concept needs, and identify the capabilities to validate as your engineering team grows.

06

Space investors and venture teams

Request a technical briefing on SEP, its development status and the mission-engineering workflows it is being built to support.
