SolarSystem.NPUpdateInterval Property

Top 

Description

Update method applied when reading earth's nutation and precession information from the planetary forces file (e.g., DE430).

 

A positive value will cause the nutation and precession to be updated to the nearest specified seconds. This is the quantitized mode.

 

A value of zero will cause the nutation and precession to be updated to the full accuracy supplied. This is the instantaneous mode.

 

A negative value will cause the nutation and precession to be updated when the requested reading deviates by more that the absolute value in seconds from the previous update. This is the hysteresis mode.

 

Timing Precision Mode

This page describes functionality in nanosecond timing precision mode.
