Day and Night World Map
Where is day or night in the world ? Day and night worldmap show the current dayzones and nightzones straight into a worldmap.



Degree Converter
To convert decimal to degrees, minutes and seconds you can just enter the data and we will convert for you.



Extract data from NORAD TLE  
Use this free Excel spreadsheet to extract data from NORAD Two-Line Element format.



Find Latitude/Longitude with Google Maps
Find city Latitude and Longitude in the world with Google Maps.



Find Latitude/Longitude with World Cities List
Find Latitude/Longitude with World Cities List.



Find Magnetic Declination with Google Maps  
Find Magnetic Declination for any place on Earth with Google Maps. This utility uses World Magnetic Model for 2010-2015 published by the NGDC to calculate magnetic declination. Magnetic declination is the magnetic variation or the magnetic compass correction. It is the angle formed between true north and the magnetic north. Declination is measured positive east and negative west. For surveying practices, magnetic declination is the angle through which a magnetic compass bearing must be rotated in order to point to the true bearing as opposed to the magnetic bearing. Here the true bearing is taken as the angle measured from true North.



Find a Route with Google Maps
Find a route from a place to other with Google Maps.



Find the International Space Station (ISS) with Google Maps  
Shows you where the International Space Station (ISS) is currently located. Uses the NORAD TLE sets. This utility require Google Earth installed to realtime track. Try it !



List of Rocket Launch Centers with Google Maps  
Shows where the satellite launch centers are currently located. This utility require Google Map or Google Earth. Try it !



Free Space Loss
The Ku-band satellites are located on the same arc as the C-band satellites, so the distances from earth to the satellites are essentially the same (22245 miles or 35800 Kilometers). But because the frequency is so much higher on Ku-band than it is on C-band, the transmitted power path loss for the Ku-band satellites is much higher. Use this free Space Loss calculator and get space loss in dB.



Generate Clarke Belt Snapshot  
Generate yourself a "Clarke Belt Snapshot" with the latest satellite longitudes. This is a experimental utility. It convert geostationary Two-Line Elements file into a satellite longitudes table with satellite longitude and inclination. This utility requires only TLE file from CELESTRAK or NASA. The satellites position are obtained using the NORAD SGP4/SDP4 prediction models.



Great Circle Distance
This calculator computes the great circle distance between two points on the earth's surface. The program is operated by entering two geographic points and then pressing the "Calculate" button. The entry form allows you to enter geographic position. The calculator computes distance in Statute Miles, Nautical Miles and Kilometres. Enter latitude and longitude of two places, and find out the distance between them.



Dish Alignment Widget with Google Maps  
It is the most practical and compact than competitors. This utility detects the city where you are. It shows on screen the latitude, longitude and magnetic declination of the site. You can calculate at once the azimuth, azimuth magnetic, elevation and LNB skew from your city. You can improve the accuracy of the results by putting the mark on your home. TrackingSat has proven to be a great tool. It is one of the most visited pages on our website. You can put this Widget on your website. Try it.



Satellites in Clarke Belt  
See this list and have more details about the desired satellite.



Sunrise and Sunset
The program retrieves the current date from your computer, and fills the month, day and year fields. To perform calculations for a different date, simply select a month in the pull down menu, and enter the day and four digit year in the appropriate input boxes. When entering a day or year, you will need to click the "Calculate Sunrise/Sunset" button to update the results for this date.



Timezone Clock
The Interactive world time zones clock calculates the time around the globe. The clock is based on your computer's time and time zone settings so these must be correct in order to get accurate time conversions.



Timezone Map
Found time zone from your country.
