GPS time in TerraScan

In TerraScan the Time conversion can convert to/from GPS seconds-of-week, GPS standard time  and GPS time. Projects can store GPS seconds-of-week, GPS standard time  and GPS time in LAS 1.2, and later formats, or Fast Binary.

GPS seconds-of-week‘ time stamps are between 0 and 604800, where the clock resets at midnight Saturday night to Sunday morning.

GPS standard time‘ defined by LAS standard as the Adjusted Standard Time, (satellite GPS Time minus 1 x 10^9), smaller than one 1 000 000 000

GPS time = GPS standard time + 1 000 000 000, or is the unadjusted GPS standard time (continuously counting from Jan 6, 1980)

  • GPS time‘ stamps are right now bigger than one 1 000 000 000
  • May be easier for some customers who need to track time vs standard time. Difference is one billion seconds.
