GPS devices vary in sensitivity, speed, vulnerability to multipath propagation , and other performance parameters. High Sensitivity GPS receivers use large banks of correlators [ clarification needed ] [ citation needed ] and digital signal processing to search for GPS signals very quickly. This results in very fast times to first fix when the signals are at their normal levels, for example outdoors.

When GPS signals are weak, for example indoors, the extra processing power can be used to integrate weak signals to the point where they can be used to provide a position or timing solution.

    In its early development, access to user location services was driven by European and American emergency services to help locate callers. All smartphone operating systems offer free mapping and navigational services that require a data connection; some allow the pre-purchase and downloading of maps but the demand for this is diminishing as data connection reliant maps can generally be cached anyway.

    There are many navigation applications and new versions are constantly being introduced. Consequently, almost any smartphone now qualifies as a personal navigation assistant. The use of mobile phones as navigational devices has outstripped the use of standalone GPS devices. Assisted GPS A-GPS uses a combination of satellite data and cell tower data to shorten the time to first fix , reduce the need to download a satellite almanac periodically and to help resolve a location when satellite signals are disturbed by the proximity of large buildings.

    When out of range of a cell tower the location performance of a phone using A-GPS may be reduced. Phones with an A-GPS based hybrid positioning system can maintain a location fix when GPS signals are inadequate by cell tower triangulation and WiFi hotspot locations. Most smartphones download a satellite almanac when online to accelerate a GPS fix when out of cell tower range.

    A GPS navigation system can help aviators always know their position and its surroundings in all of its phases starting from its departure all the way to its landing point. Also, a GPS now allows an aviator from start to finish not to have to depend on ground infrastructures and allows them to be able to have a preferred route from its departure and landing point, but not only do they play a part in preferred routes they also help in airports that lack ground-based navigation and surveillance equipment.

    With the use of a GPS for aviators, it saves time and money being used on fuel. More efficient air routes are continuing to expand every day. There are now some GPS units that allow aviators to get a clearer look in areas where the satellite is augmented to be able to have safe landings in bad visibility conditions. There have now been two new signals made for GPS, the first being made to help in critical conditions in the sky and the other will make GPS more of a robust navigation service.

    Many aviator services have now made it a required service to use a GPS.
