Integrated SET

The Earth's crust flexes during the day with solar and lunar gravity-induced tides, resulting in a distance variance from the earth's surface to its center by as much as 40cm in height. NavCom corrects for these variations by employing real-time Integrated SET (Solid Earth Tides) corrections in our StarFire™ positioning algorithm.


Benefiting both land and sea applications, Integrated SET allows our GPS to automatically adjust for the effects of solid earth tides in both horizontal and vertical dimensions throughout the lunar cycle, providing for the most accurate position solution available. The Integrated SET feature is based on the highly accepted Sinko Solid Earth Tide model that NavCom has adapted to run in real time.


Integrated SET comes standard in all NavCom StarFire GPS receivers operating software version 3.0.0 or higher.
