P-Track displays near real-time Satellite position, track, health, and coverage information on a 3-D interactive globe. Full retina display is supported for both iPhone and iPad. 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 its 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.

P-Track now supports position, track, velocity, and flyby information for the following Amateur Satellites:
ALMASAT-1
RAX-2
SRMSAT
JUGNU
UWE-2
BEESAT
KKS-1 (KISEKI)
STARS (KUKAI)
HAMSAT
JAS 2
ITAMSAT
OSCAR 11 (UoSAT 2)
OSCAR 7

Many new features to come - I hope you enjoy this App!

Pros and cons of P-Track Satellite Viewer app for iPhone and iPad

P-Track Satellite Viewer app good for

Sorta and the app is silky smooth to operate.. Great work by the developer
From Info setting, select Ionosphere, then "Ionoshperic" (miss-spelled) can be seen on the screen. (See 2nd preview image from left)
いいのでバナーなしがほしいです。iPhone 6 Plusに最適化してほしい。

Some bad moments

On opening one often gets a "Warning no data for selected Satellite". It the removes ALL controls and one sits with an app which is a "brick". Cant get back to a menu, cant select any other Sat. :-). If you are lucky enough to hit "i" before it bricks, you can scroll and select. App seems okay then. Overall: Disappointed, uninstalled in minutes.
The new update doesnt work. I tried launching it a few times on my iPhone 4S and it locked up and then shut down.
I was a customer of the previous version and the artwork in 1.9 is so much better! The App works fine for me.. Can you please add notifications of ISS flyovers?
Great ideas in this app! I like the way you can move the globe and see where the satellites are at! Can you add amateur SATS?
This is so cool!!!! I can use it ... Friendly user:) Some apps are not friendly users. Great app.
I hear this app was built by a SBAS engineer for his own use. Works for me! Now I know exactly which patch of sky to shoot at to bring down those ornery gps satellites. Yeehaw!
