      APPS will produce the following output:
    • All coordinates are in ITRF2014
    • Summary file: Run status (success/error), key output values, list of output.
    • XYZ file: Time, X, Y, Z coordianates, together with their formal errors.
    • GIPSY TDP file: Time, X, Y, Z coordinates in GIPSY's TDP format.
    • Instant positioning for web users, where you will see the X, Y, Z coordinates and
      the Lat, Lon, Height on this web site
    • Access information: URL of output files and password
