This program was created in cooperation with Vladislav Yushakov.

New version 2.023!!!

Download SatCE v2.03 for Pocket PC WM5 WM6 (VGA resolution): SatCe 2.02 VGA version

Download SatCE v1.51 for Pocket PC CE2002, 2003: SatCE.arm.CAB (1.2 Mb)

For more SatCE  files please visit file galleries

I work on the Android version of SatCE

In case of blanc screen after reinstalation you have to edit registry and delete everythink from the SatCE entry.

In version 1.5 the problem is solved.

If you like my projects you can support them here. The registration code of SatCE is: 19771207

Image SatCE is a satellite tracking program.

    To correctly predict the satellite position you need fresh *.tle data (not more than 30 days old)!!! Also the accurate location Lat and Lon (this can be taken from GPS or from the list of cities in the program) and local time. The UTC time is taken from Windows CE system therefore set the right time zone and time at your location in windows settings. Now the clock can be synchronised with the GPS atomic time.  This program is using SDP4/SGP4 or SDP8/SGP8 algorithms to calculate near and far satellite positions in space. SDP8/SGP8 algoritms are 5-15% faster than SDP4/SGP4. In all calculations of lat and lon the oblate Earth shape is used. The program uses GAPI engine for graphics and API for text mode in version 1.51 and ealier in version 2.0 and higher everything is in API. SatCE can track up to 150 satellites at once (but this is not the hard limit). SatCE reads *.tle with standard two lines elements (tle files contain orbital parameters) or read them directly from internet. SatCE is very fast (much faster than I could find for sat tracking in internet for PocketPC)! A screen is updated every second without any delay with all these fancy things. There is also a lot of data like satellite parameters, GPS, moon distance its face size and some information about sun and planets. Satellite can be selected in map and sky mode by taping it with the stick. Only selected satellites from menu bar are displayed (by default all satellites are selected). Come back to text mode is with help of enter button (just push every one if you don't know which one it is) or taping the right top corner. You can find more information about space objects and related topics http://www.celestrak.com/. From this location you can also get the last *.tle files.

The map shows satellites positions (selected satellites have different drawings), the visibility area (green line) for selected satellite and the satellite path (the blue color of the path indicates eclipsed satellites and yelow not one). Additionally in this mode the program shows position of the sun, the moon and day/night line. The observer position is indicated by red circle. The selected satellite is surrounded by red dots. The map is downloaded from file (skins directory). This allows to create your own earth maps for day and night.

The sky view shows satellites(selected satellites have different bitmaps), selected satellite coming(yellow) and past(grey) path, position of the moon and the sun. When sun is below horisont its azymuth is presented by yelow square on the bigest circle. Stars until 5 magnitude (around 1700 stars) with constellations graphs. All directions are described. The selected satellite is surrounded by red dots. The screen can be rotated with LEFT/RIGHT buttons. The position of stars and satellites is calculated every second (with stars until 4th magnitude). The picture on the right shows calculated GPS satellites together with positions of GPS satellites obtained from GPS receiver. The GPS signal is represented by blue bars. The sky mode can be rotated according to the compas from GPS(you have to walk for a moment). The view can be change from mirror image(like reflection from the water) to the direct sky(like thought umbrella). The Iridium flare is represented by line (red or yelow depending on the intensity)on the path of satellite with small text information right top corner). The eclipset path is represented by blue line.

The space mode shows satellites(on left), moon, sun and planets(on right) in 3D space. You can freely rotate the scene in all directions with the stick. Also you can zoom in and zoom out the scene with LEFT/RIGHT buttons. The selected satellite is in color together with its trajectory. The location of the observer on the earth is indicated by yellow dot. Positions of all satellites and the observer(rotation of the earth) are calculated every second.


In the text mode the program shows important numbers. The satellite can be changed from menu bar (the number indicates the satellite from tle file) and with buttons (UP/DOWN). The observer position can be entered from menu bar (lon(E) deg, lat(N) deg, alt km)or when GPS tracking is selected, directly from GPS.

Predict dialog allows to predict selected satellite passes and Iridium flares. With the "only vissible passes" option in Settings dialog the program will predict only vissible satellites in Predict dialog. In this case also the expected magnitude can be sellected (Settings dialog). Selected satellite from the list will be an active satellite. The time will be paused for selected pass.

Many thank for testing new versions of SatCE to: Jan from Lufthansa Technik at Frankfurt Main Airport in Germany, Wayne 73's KC5HPU, Wojciech Scigala for detailed analyze and correction of the GPS comunication code. Thanks to Sebastian Stoff author of "Orbitron" for recommendation of the very suitable web-page.

eddie, 11:29 AEST, Sat 22 of Jun, 2024: Offline wiki repair is mostly done. It is running on tiki-27-alpha
eddie, 18:14 AEST, Sun 12 of May, 2024: Phase one of wiki repair is to upgrade to V22 (the last version with image galleries). All 150 images in the wiki-up directory are broken and need manual wiki page repairs.
admin2, 19:45 AEST, Sun 28 of Apr, 2024: Tested tiki 26.2 on a raspberry pi. Tiki 26 does not support image galleries so I have to try again after migrating images to file galleries.
eddie, 13:04 AEST, Thu 10 of Aug, 2023: Offline tiki 26 upgrade went badly. Waiting for 26.1. Will limp on.
System Administrator, 18:45 AEST, Wed 26 of Jul, 2023: Recovered from lockout but unable to upgrade to V24
