The database contains 28 types of data for each satellite, including technical information about each satellite (mass, power, launch date, expected lifetime) and its orbit (apogee, perigee, inclination, and period), as well as information on what the satellite is used for, and who owns, operates, and built the satellite. The constellation requires a minimum of 24 operational satellites, and the typical number active is 31. The frequencies shown, when provided, are those captured by enthusiasts or informed by the official organizations of disclosure. They could be considered part of the GPS satellite constellation and would answer questions I've seen on some forums regarding PRNs over 32. Once launched, GPS satellites do not change their plane assignment but slot assignments are somewhat arbitrary and are subject to change. Numbers in parentheses refer to non-operational satellites. Ils se répartissent sur six orbites distinctes à raison de quatre satellites par orbite. Also, it is very easy to transmit a carrier radio signal to a geostationary satellite and thus interfere with the legitimate uses of the satellite's transponder. And thus, in 1964 the Transit system was deployed for the purpose. Three of the seven satellites in constellation are located in geostationary orbit (GEO) and four in inclined geosynchronous orbit (IGSO). Welcome to Satellite Map.
