GPS Week Second To Days Since Era Converter
Convert GPS week/seconds-of-week to days since the GPS era start (1980-01-06) with rollover count.
Description
Convert GPS week/seconds-of-week to days since the GPS era start (1980-01-06) with rollover count.
GPS Week Second To Days Since Era Converter is a focused tool for the following task. Convert GPS week/seconds-of-week to days since the GPS era start (1980-01-06) with rollover count. It reports W_abs, days from the values you provide rather than inventing measurements, coefficients, or professional judgment that are not part of the input.
When to use GPS Week Second To Days Since Era Converter
Use this seismology calculation to reproduce a stated convention, screen observations, or compare scenarios whose units, coordinate conventions, catalog selection, and model assumptions are known.
- week
- Required integer. GPS week number (mod-1024 as broadcast).
- roll
- Optional integer. Rollovers since the 1999 epoch.
The cited overview of Seismology supplies background for the terminology and domain context used by this tool.1
How GPS Week Second To Days Since Era Converter works
Convert GPS week/seconds-of-week to days since the GPS era start (1980-01-06) with rollover count. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.
- W_abs
- Returned integer. Absolute week since GPS era.
- days
- Returned integer. Days since 1980-01-06.
Limitations and assumptions
- Earth structure, source geometry, path effects, site response, instrument response, catalog completeness, uncertainty, and the fitted range can dominate the accuracy of simplified seismic calculations.
- roll must be at least 0.
- Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.
Alternative or Complementary approaches
For analysis or hazard decisions, retain uncertainty and provenance and compare the result with waveform processing, calibrated regional models, and guidance from qualified seismologists or the responsible agency.
