Starlink Coverage Tracker - v2.0.5 Release Notes

- Re-write of parts of the simulation engine, fixing some bugs and improving performance.

- Added capacity simulation options to increase gateway capacity, set minimum and maximum gateway capacities.

- Added setting for Ku band service beam maximum capacity.

- Added option to load a TLE set with the completed Gen1 constellation (4408 satellites).

- Added hover tooltips to several settings.

- Cross-plane ISL links are used to propagate gateway connectivity to orbital planes not within gateway range.

- Added "freeze time" option. Click the calendar, and enter a Unix timestamp. Simulator will render at that time over and over. Useful to see how changes in simulation settings affect capacity while keeping constellation configuration constant.

- Re-written classifier for operational vs standby satellites.

- Added option to enable the use of standby satellites for service.

Previous release v2.0.0

- Added capacity simulation. Please see this post on Medium for a deep-dive on how it works.

- Complete re-write of the simulation engine code, to increase performance.

- Several bug fixes around temporary gateways and ISL links.

- Added the usable portion of the user terminal's field of view as green H3 cells. This changes with location, terminal tilt, etc.

- Removed the satellite list, as it was no longer useful due to the number of simultaneous satellites covering a single location.

- Removed terminal and gateway heatmaps, for the same reason.

- Settings stored in localStorage are reset when first loading v2.0, due to several breaking changes made.

Starlink Coverage Tracker

This tool was created to help view Starlink coverage over any place on Earth, and includes:

Realtime display of Starlink satellites currently in orbit.
Display of satellite altitude vs. operational status in color coded format.
Show orbit path of selected satellite.
Show azimuth and elevation of selected satellite, if within coverage of customer location (green dot).
Show links between satellites and known Gateway locations (orange lines).
Show links between satellites and customer location (green lines).
Show estimated service status (no link, single-satellite link in yellow, multi-satellite link in blue).
Show relative percentage of service from one satellite, multiple satellites, and no service.
Given a Dishy tilt angle in Settings, the resulting FOV is shown on the map. At zero tilt, the 40º visibility line is drawn.
Heatmap of the area where a viable link from a satellite is possible.
Coverage of a gateway and heatmap of satellites it serves.
Plot the contour of the 3dB spot beam over the customer's location.
Plot the H3 cells that fall under the spot beam at the customer's location.

Basic instructions:

Set your Home location by clicking the button, then clicking on the map.
Set the maximum steering angle between Home location and satellites (25° to 45°) in the Settings window, found by clicking the button.
Home location, once set, is stored in the browser's local storage, and will be remembered across sessions.
Click on a satellite to follow its path. The satellite's altitude will be shown in the vertical gauge.
If the selected satellite is providing service to the Home location (green line), azimuth and elevation will also be shown.
Satellites that are within 22° of the Clarke belt are automatically discounted as a viable link, even if visible.
Use the button to add a temporary Gateway anywhere on the map. These are deleted if you restart the browser or refresh the page.
Adjust the Dishy tilt angle to generate a FOV that matches your particular antenna, or to see how it affects coverage at a location.
Enable heatmap generation in Settings, to see the area where viable links from satellites are possible. This feature auto-disables after five hours, to conserve memory.
View the polar plot of azimuths where most satellites serve your location from, this can help you determine what trees to trim!
The contour of the spot beam from the primary satellite is dynamically plotted over your location.
If you zoom in close enough, you will see the H3 cells that fall under the spot beam (Note: NOT Starlink's cells, but close!)

Important caveats!

No accuracy, service quality, availability, or other related information is implied or guaranteed.
All data on this site is provided as a best-effort, not peer-reviewed or quality controlled.
