Orbital Tracking Information
How does the live data from the International
Space Station get into my web browser?
Computers at JSC receive International Space Station
telemetry data via satellite downlink, process
the data, and make it available through the Information
Sharing Protocol (ISP). The Advanced International
Space Station Tracking Monitor uses ISPresso,
a Java version of the ISP client library which
allows Java-enabled browsers to tap directly into
ISP telemetry streams. Using ISPresso, your browser
will receive the ISP data directly from the ISP
stream delivered to the Human Spaceflight web
server from the Mission Control Center.
What information can I get from the tracking
monitor?
(A)
The map of the world.
(B) The International Space Station; the center
represents its current latitude/longitude.
(C) The blue line tracks the International Space
Station's path over the ground.
(D) The red circle around the International Space
Station represents its horizon (the area on the
ground from which the orbiter is visible).
(E) Header Information:
(GMT, Houston and Moscow times are displayed in
DAYS/HOURS:MIN:SEC format. These times are based
on the user's system clock and may vary accordingly.
You can synchronize your computer system with
the atomic clock at the U.S.
Naval Observatory).
- GMT: Greenwich Mean Time
- Lat: Latitude of the orbiter
- Long: Longitude of the orbiter
- Alt: Current altitude of orbiter in kilometers
- Spd: The Orbiter speed in meters per second
(F) The yellow ball represents the Sun's zenith
(high noon on earth).
(G)The Orbital Tracking Application also provides
location data on the space shuttle during missions.
