#Nasa iss real time tracking update

The orbit ground track line is drawn by default. This keeps the relative motion of the map roughly equal at all scales within a given range. As you drag the slider right, it increases by 1 second up to a maximum interval of 6 seconds.

#Nasa iss real time tracking update

With the slider all the way to the left, the update interval is set at 1 second. The time interval between map updates is automatically set from 1 to 6 seconds, based upon the zoom slider setting. There are three styles of markers, which you can select in Settings: You can set the map scale range in Settings to any of the following ranges (in degrees): This changes the scale of the map, which is displayed in degrees to the right of the zoom slider.

To zoom in or out of the map, use the slider control at the top of the map.

Hybrid (the default setting: shows borders, names, roads, and terrain).

Standard (shows names, roads, and borders).

You can select from the following map types in Settings from the Tracking screen: To locate and track the International Space Station in real time, tap the play button at the bottom of the screen. Tap the back button to return to the map and resume tracking.

Calendar events are saved in your default calendar.

When asked, tap 'OK.' You can change this permission in your device's Settings app.

You must give ISS Real-Time Tracker 3D access to your location.

If there are buildings, trees, or other obstructions, and depending upon the weather and other viewing conditions, you may not be able to spot the space station.

This may change in the future, as the magnitude data are provided for the TSS.

Tiangong (TSS) pass predictions do not include the magnitude of the passes and are, therefore, not rated.

Overhead passes returned are only those visible from your location for at least 300 seconds (5 minutes) and where the ISS is illuminated by the Sun.

The pass predictions become less certain the further out in time they go.

Pull-to-Refreshĭrag down the table to refresh the data. To change the number of days so that the app remembers your setting for next time, change it in Settings. Tap the Calendar icon at the top-right of the screen to change the number of days to compute and refresh the list. The starting and ending times for the pass are saved in the event in your calendar, along with the maximum magnitude, as well as the starting, maximum, and ending azimuths and elevations for the pass. When adding a pass to your calendar, two alerts will be set: the first for 1 hour before, and the second for 15 minutes before the start of the pass. Tap any pass in the table to add it as an event in your calendar. The table will automatically refresh and present passes for the selected target. Tap the switch target button in the navigation bar to switch between the ISS, TSS (Chinese space station named Tiangong), and Hubble Space Telescope. Passes are rated with 0, 1, 2, 3, or 4 stars corresponding to relatively poor, fair, good, better, or best, respectively. The brightest passes get the highest ratings.

Time, azimuth, elevation, and compass direction for the start time, max elevation time, and end timeĮach pass is rated based on its maximum magnitude (i.e., brightness).

Max visual magnitude (using same scale as astronomical brightness, i.e., apparent magnitude).

Visible duration (in minutes and seconds).

The passes are listed in chronological order along with detailed viewing data. The default number of days to predict passes is set in Settings and can be overridden in the Passes screen. Then, it computes the ISS, TSS, or Hubble passes that should be visible (weather permitting) from your location. First, ISS Real-Time Tracker 3D gets your current location's coordinates. Tapping the binoculars icon at the bottom of the main screen starts the process of computing up-coming visible ISS, TSS, or Hubble Space Telescope passes.
