... Combining dual-frequency carrier phase GPS receivers and inertial navigation units on board aircraft platforms enables these instnunents to produce ice-sheet elevation maps with spatial accuracies in the range of 10 to 20 centimeters. George Born and Kevin Key discussed using the GPS for satellite altimetry to measurement of changes in global sea level.

... Nevertheless, the first issue addressed by the working group on dynamic positioning and navigation was to define a "dynanuc application" in contrast to a "static application." There was broad agreement that dynamic TABLE 4-1 Spatial Resolution Requirements for Dynamic Applicationsa 19 applications involve vehicles or platfonns designed to move on or above the Earth's surface on human time scales. Platforms include satellites, aircraft, trucks, cars, trains, boats, ships, buoys, drifters, dropsondes, and, potentially, autonomous underwater vehicles.

... They do not represent requirements defined by an internationally recognized standardization committee or government agency. The working group distinguished between the high temporal sampling rates needed at the platform receiver and the sampling rates of GPS observables at reference stations, which are used to determine differential corrections.
