GPS Time Converter Utility

When Trajectory files are added into GeoCue, the properties that are displayed show the the start and end time of the file in GPS Week Seconds. If the GeoCue project is in Adjusted GPS Standard Time, then the GPS week is also displayed within the property field. The times are not displayed in Adjusted GPS Standard Time as the sensor trajectory formats do not typically support those timestamp values in their time fields.

This may be confusing if a user wants to see what the GPS Adjusted Standard Time is on the file. With this in mind there is a GPS Time Converter Utility that can be used to convert between different times. The utility can be used independent of GeoCue or it can be added directly into the program.

Executable Usage

The GPS Time Converter executable is installed with the GeoCue LIDAR 1 CuePac and is typically located under C:\Program Files\GeoCue\LIDAR 1 CuePac\GPSTimeConverter.exe. Optionally, you may download the utility from the knowledge base (20MB).

Once the dialog is opened a user has three options:

  1. Specify the Date/Time to determine Elapsed GPS Seconds and GPS Week/Seconds
  2. Specify the Elapsed GPS Seconds to determine Date/Time and GPS Week/Seconds
  3. Specify the GPS Week/Seconds to determine Elapsed GPS Seconds and Date/Time

After specifying the value in one of the fields click Update to update the information in the other fields
