dodge is a Windows-friendly app for anyone who wants a clear, daily view of space traffic. It opens to a daily screen showing every close approach between Starlink satellites and the rest of low Earth orbit. Each close approach is attributed, signed, and verifiable. The app uses SGP4 on public data, so the information is based on open orbital data rather than private guesses.
You do not need to be a programmer, satellite expert, or data scientist to use dodge. The goal is simple: give you a readable daily screen that answers the question, “What is happening between Starlink and the rest of low Earth orbit today?”
dodge is a desktop application that turns public satellite data into a daily close approach screen. Low Earth orbit is busy. Thousands of satellites and pieces of orbital debris move around the planet at high speed. When two objects pass near each other, that is called a close approach. dodge focuses on close approaches involving Starlink and the other objects in low Earth orbit.

dodge is a Windows application that gives you one clear, daily screen of every close approach between Starlink satellites and the rest of low Earth orbit. Each event is attributed, signed, and verifiable. The calculations use SGP4 on public data, so the results are transparent and repeatable. You do not need to be a programmer, an orbital analyst, or a data scientist to use it. You open the app, you read the screen, and you understand what happened in orbit today.
Low Earth orbit is crowded. Thousands of active satellites and pieces of orbital debris circle the planet at extremely high speeds. When two objects pass near each other, that moment is called a close approach. Most of the time nothing happens, but tracking these moments matters for space safety.
dodge focuses on Starlink, the large satellite constellation operated by SpaceX. Every day, the app produces a screen showing all the close approaches between Starlink spacecraft and everything else in low Earth orbit. That includes other satellites, spent rocket bodies, and debris.
Instead of handing you raw numbers and expecting you to interpret them, dodge presents the day’s events in a readable layout. You see what passed near what, how close the approach was, and when it happened. Nothing is hidden behind a login, a subscription, or a proprietary data feed.

Download dodge from the official releases page
The releases page is the only place you should get dodge. It lists the available versions of the application for Windows. Choose the latest release and download it to your computer.
After the download finishes, open the folder where your browser saved the file. Double-click the downloaded file to begin. Windows may show a security prompt the first time you run an application from the internet. If you see a SmartScreen window, click the option that lets you continue, and the app will start.
Because dodge is distributed through GitHub Releases, each version is published openly. You can return to the same page later to check for newer versions.
When dodge opens, it loads the current day’s screening data and shows you the daily close approach screen. This is the main view of the application, and for most people it is the only view they will ever need.
The screen is organized around the day’s events. Each row or entry represents one close approach involving a Starlink satellite. The layout is designed to be scanned quickly, so you can get a sense of the day at a glance and then look more closely at any event that interests you.
On first launch you may see the app gathering and preparing the current dataset. This is normal. Public orbital data is refreshed regularly, and the first run may take a little longer than later runs because the app needs to build its local picture of the day.
The daily screen is where dodge earns its name. Every close approach shown follows the same structure, so once you understand one entry, you understand them all.
Each entry tells you which Starlink satellite was involved, which other object it approached, and how close the two came to each other. The time of the approach is shown so you can place the event in the context of the day. The approach distance is presented in a way that lets you compare events: smaller numbers mean closer passes.
The screen is built for daily reading. You are meant to open it once a day and see what is new. Events are not buried under layers of menus. The information you care about is on the surface.
If an event catches your attention, you can look at the details behind it. Attribution tells you where the underlying data came from. The signature and verification information lets you confirm that the event record has not been altered.
Trust matters when you are reading about objects moving at orbital speeds. dodge does not ask you to simply believe what is on the screen.
Every close approach record is attributed, meaning its source data is identified. The record is signed, meaning it carries a cryptographic signature that ties it to its origin. And it is verifiable, meaning you can check that signature and confirm the record is exactly what was produced. This is the same approach used in modern open-source software supply chains, and dodge applies it to space situational awareness.
For most users, this simply means the daily screen is trustworthy. For anyone who wants to check further, the verification path is available.
dodge uses SGP4, a widely used orbital propagation model, applied to public data. Public data means the underlying orbital information comes from open sources rather than a closed, private feed. SGP4 is a standard method for predicting where objects will be at a given time.
The combination matters. Because the data is public, anyone can inspect it. Because SGP4 is a known method, the calculations can be reproduced. dodge does not invent a new way of measuring the sky. It applies well-understood methods openly and shows you the result.
dodge is built for people who are curious about what is happening above them. That includes space enthusiasts who follow Starlink and orbital debris, journalists who need a clear daily view of close approaches, students learning about orbital mechanics, and professionals who want a quick, readable daily reference without building their own pipeline.
It is also for people who value open data and verifiable records. The topics behind dodge include space situational awareness, conjunction screening, data visualization, open data, orbital debris, and space traffic. If any of those phrases mean something to you, the daily screen will feel familiar. If they do not, you can still read the screen and understand the day’s events.

Open dodge in the morning. The daily screen loads the current day’s close approach events. Scan the list to see how busy the day is. Look at the closest events first, since those are the ones most worth understanding. Read the attribution when an event interests you. If you want to confirm a record, use the verification information provided.
Close the app when you are done. Come back tomorrow for a fresh daily screen. That is the whole workflow.
Do I need an account? No. dodge does not require a login to view the daily screen.
Do I need to install Python or any developer tools? No. dodge is provided as a downloadable application for Windows. Visit the releases page and download it.
Where does the data come from? From public orbital data, processed with SGP4.
What does “signed and verifiable” mean for me? It means the close approach records carry proof of origin and can be checked. For everyday use, it means you can trust the daily screen.
Can I use dodge on a computer without internet access? The daily screen depends on current public data, so an internet connection is needed to refresh it.
How often is the screen updated? The design goal is a daily screen. Open the app each day to see the latest view.
New versions of dodge appear on the releases page. Bookmark it, and check back occasionally. When a new version is available, download it the same way you downloaded the first one and use the newer copy.
