Time to first fix. Time to first fix ( TTFF) is a measure of the time required for a GPS navigation device to acquire satellite signals and navigation data, and calculate a position solution (called a fix ). An animation depicting the orbits of GPS satellites in medium Earth orbit.
Satélite NAVSTAR GPS. El Sistema de Posicionamiento Global ( GPS; en inglés: Global Positioning System ), originalmente Navstar GPS, es un sistema que permite a un dispositivo receptor localizar su propia posición sobre la Tierra con una precisión de hasta centímetros (si se utiliza GPS diferencial), aunque lo común son unos pocos metros.
Global Positioning System ( GPS) er et satellit -baseret system ejet og styret af det amerikanske forsvar, der kan benyttes til at positionsbestemme hvor man befinder sig overalt på kloden. Systemet virker ved at 24 satellitter bevæger sig omkring Jorden i 6 bestemte baner, dvs. fire i hver bane. Det medfører at der altid er tolv satellitter ...
GPS assistido (A-GPS) é um sistema que pode, sob certas condições, melhorar o desempenho de inicialização, pois recebe dados de suporte através de uma conexão de dados (por exemplo, GPRS ou 3G ), ajudando seu aparelho a calcular as coordenadas da sua posição atual quando recebe informações de satélites.

Differential GPS. Transportable DGPS reference station Baseline HD by CLAAS for use in satellite-assisted steering systems in modern agriculture. Differential Global Positioning Systems ( DGPSs) supplement and enhance the positional data available from global navigation satellite systems (GNSSs). A DGPS for GPS can increase accuracy by about a ...
The GPS makes corrections for receiver clock errors and other effects but there are still residual errors which are not corrected. GPS receiver position is computed based on data received from the satellites. Errors depend on geometric dilution of precision and the sources listed in the table below.
2023年10月19日 · The global positioning system (GPS) is a network of satellites and receiving devices used to determine the location of something on Earth. Some GPS receivers are so accurate they can establish their location within one centimeter (0.4 inches). GPS receivers provide location in latitude, longitude, and altitude.
