GeoNotes: A Location-based Information System for Public Spaces
The basic idea behind location-based information systems is to connect information pieces to positions in outdoor or indoor space. Through position technologies such as Global Positioning System (GPS), GSM positioning, Wireless LAN positioning o
GPS system simulation methodology
The following topics are presented: background; Global Positioning System (GPS) methodology overview; the graphical user interface (GUI); current models; application to space nuclear power/propulsion; and interfacing requirements. The discussion is presented in vugraph form
Shuttle Global Positioning System (GPS) design study
The effects of oscillator noise on Shuttle Global Positioning System (GPS) receiver performance, GPS navigation system self-test, GPS ground transmitter design to augment shuttle navigation, the effect of ionospheric delay modelling on GPS receiver design, and GPS receiver tracking of Shuttle transient maneuvers were investigated
Codeless GPS Applications to Multi-Path: CGAMP
Cordless Global Positioning System (GPS) Applications to Multi-Path (CGAMP) is meeting the challenge of exploiting the L-band signals from the Global Positioning System (GPS) satellites for the measurement of the impulse response of radio transmission channels over space-Earth paths. This approach was originally suggested by E. K. Smith and has been pursued by J. Lemmon, without an affordable implementation being identifiable. In addition to the high cost of a suitable P code correlating GPS receiver, there is also the major impediment of the often announced Department of Defense policy of selective availability/anti-spoof (SA/AS) that clouds reliable access to the wideband (20 MHz) P channel of the GPS signals without cryptographic access. A technique proposed by MacDoran utilizes codeless methods for exploiting the P channel signals implemented by the use of a pair of antennas and cross correlation signal detection
APLIKASI PELACAK LOKASI, KECEPATAN, ARAH DENGAN MENGGUNAKAN GLOBAL POSITIONING SYSTEM (GPS) DAN MENGHASILKAN OUTPUT FILE EKSTENSI KEYHOLE MARKUP LANGUAGE (KML) BERBASIS ANDROID
Dengan perkembangan teknologi yang kian maju, manusia dapat membuat
berbagai macam peralatan sebagai alat bantu dalam menjalankan berbagai
aktivitas untuk mendukung produktifitas. Salah satunya adalah perangkat
Handphone berbasiskan system operasi Android yang mengalami perkembangan
pesat. Android sebagai sistem operasi yang dapat ditanamkan pada perangkat
handphone memiliki kemampuan untuk dapat diinstal aplikasi-aplikasi yang
diperlukan oleh pengguna, dimana perangkat Handphone berbasis Android sudah
dilengkapi beragam teknologi canggih, salah satunya teknologi Global
Positioning System (GPS) yang berfungsi sebagai penanda/pelacak posisi saat ini.
Sehingga dengan adanya teknologi ini pengguna semakin mudah untuk melacak
posisi keberadaan dan rute yang telah dilaluinya.
Tugas akhir ini membahas perancangan antar muka dan pembuatan
aplikasi pelacak posisi, kecepatan, arah dan menghasilkan output file Keyhole
Markup Language (KML), yang berjalan di system operasi Android. Untuk
implementasi aplikasi menggunakan Handphone yang dilengkapi teknologi
Global Positioning System (GPS).
Pada tugas akhir ini dikembangkan aplikasi pelacak posisi, kecepatan, arah
dengan menggunakan Global Positioning System (GPS), diharapkan pengguna
yang menggunakan perangkat handphone berbasiskan sistem operasi Android
dapat terbantu untuk mengetahui informasi mengenai posisi, kecepatan, dan arah
yang disajikan oleh aplikasi ini
Contractor point of view for system development and test program
Industry's practice of testing space qualified hardware is examined. An overview of the Global Positioning System (GPS) Test Program is discussed from the component level to the sub-system compatibility tests with the space vehicle and finally to the launch site tests, all related to the Rubidium clock
Office of Spaceflight Standard Spaceborne Global Positioning System (GPS) user equipment project
The Global Positioning System (GPS) provides the following: (1) position and velocity determination to support vehicle GN&C, precise orbit determination, and payload pointing; (2) time reference to support onboard timing systems and data time tagging; (3) relative position and velocity determination to support cooperative vehicle tracking; and (4) attitude determination to support vehicle attitude control and payload pointing
