P-Track
displays near real-time Satellite position, track, health, and coverage
information on a 3-D interactive globe on your iPhone or iPad. Full Retina display is supported! You can zoom and rotate the
globe to view all available Satellites. The App allows you to see ground
tracks as well as coverage footprints for a selected satellite. The App
also displays a SkyView Plot of all satellites in view of your iPhone -
it displays Azimuth and Elevation angles of each Satellite your phone
can see. You can even view the Ephemeris, current Cartesian XYZ
coordinates (Earth Centered Earth Fixed (ECEF) and Earth Centered
Inertial(ECI)), and Latitude, Longitude, and Altitude of any chosen
satellite.
P-Track also shows you the near real-time location
and ground track of the International Space Station (ISS) and the latest
NASA Two-Line Ephemeris used to calculate it's orbit. You also are able
to view the current ISS velocity and the next time the ISS will be
viewable over your location.
This App shows the current
location, velocity, and a SkyView Plot of all 3 Wide Area Augmentation
System (WAAS) GEO Satellites - CRW-135 (Intelsat Galaxy 15), CRE-138
(ANIK F1-R), AMR-133 (INMARSAT 4F-3), as well as all GLONASS Operational
Satellites currently in orbit.
P-Track displays an up-to-date
listing of NANUs (Notice Advisory to NavStar Users). NANUs include
maintenance outages, maneuvers, and general GPS system status
information.
Another feature of P-Track is a plot showing the
current Ionospheric Activity. The data shown in this plot represents the
VTEC (Vertical Total Electron Content) in units of TECU (10^16
electrons/m^2). Ionospheric delay can have a large impact on Satellite
signal quality. The data shown here is provided by the US National
Oceanic and Atmospheric Administration using a Kalman filter data
assimilation model with a large network of ground-based dual frequency
receivers. The latency in the data shown in this plot is 15 minutes.
Many new features to come - I hope you enjoy this App!
