Orbital debris or “space junk” - http://earthobservatory.nasa.gov
Bila cuaca cerah, sesudah maghrib sampai sekitar isya atau sesudah shubuh sampai menjelang matahari terbit sempatkanlah mengamati langit. Mungkin kita beruntung bisa menyaksikan satelit yang mengorbit bumi yang terlihat seperti bintang berpindah. Satelit tersebut tampak cemerlang sekitar senja atau fajar karena memantulkan cahaya matahari yang tidak terlalu jauh dari kakai langit. Bila ingin lebih pasti melihatnya, silakan rencanakan pengamatan setelah melihat prakiraan satelit yang akan tampak dari suatu lokasi pada situs http://www.heavens-above.com. Mengamati satelit dapat menjadi hobi menyenangkan. Apalagi benda antariksa akan semakin banyak.

GPS/INS direct georeferencing
GPS aided inertial navigation systems have been available for commercial mapping applications for approximately a decade, pioneered by Canadian-based Applanix Corporation with their POS (Position and Orientation System) technology. The impact on the aerial survey and remote sensing industry has brought about a re-assessment of traditional photogrammetric methodology and the potential elimination of two fundamental mapping components, the ground control survey and corresponding aerotriangulation process.
GPS
GPS Satellite
The Global Positioning System (GPS) is a space-based radio-navigation system consisting of a constellation of satellites and a network of ground stations used for monitoring and control. A minimum of 24 GPS satellites orbit the Earth at an altitude of approximately 11,000 miles providing users with accurate information on position, velocity, and time anywhere in the world and in all weather conditions.
GPS is operated and maintained by the Department of Defense (DoD). The National Space-Based Positioning, Navigation, and Timing (PNT) Executive Committee manages GPS, while the U.S. Coast Guard acts as the civil interface to the public for GPS matters. The Federal Aviation Administration is investigating and applying the use of GPS as it pertains to aviation.
