GNSSTk 15.0.0 Release Notes

  • This release introduces a major update to the toolkit.
  • It includes the following:
    • Adding std C++17 support while deprecating std C++11 support. (api breaking)
    • Updating MultiFormatNavDataFactory and PNBMultiGNSSNavDataFactory to allow multiple independent instances. (api breaking)
    • Updating GNSSconstants Align PI, TWO_PI, SQRT_PI to the exact specification of the IS-GPS-200
  • Additionally, it contains bug fixes updates and build CI/CD updates.

Updates since v14.6.0

Known Issues

  • Some distributions (such as RHEL 8) may support different versions of gcc (such as gcc 8.x and 9.x but gcc 8.x is the default). A version of gcc (such as gcc 9 on RHEL 8) that supports C++17 and the C++17 ABI is stable must be chosen to build. Note that gcc 8.x on RHEL 8 may support some C++17 but the C++17 ABI is not stable and thus should not be used.
  • Support for MSVC14 (Microsoft Visual Studio 14) and older compilers is removed. Only Microsoft Visual Studio 19 and newer versions are supported.

Build System and Test Suite

  • Fix df_diff comparisons, off-by-one error, and cmake test usage of df_diff.

Gitlab CI

  • Update Fortify pipeline scan job
  • Update submodule ref to point to latest gnsstk-data merge
  • Fix gitlab pipeline jobs retry for only system failures.
  • Fix Fortify pipeline retry condition

Library Changes

  • Add C++17 support for Toolkits
  • Update MultiFormatNavDataFactory and PNBMultiGNSSNavDataFactory to allow multiple independent instances.
  • Update GNSSconstants Align PI, TWO_PI, SQRT_PI to the exact specification of the IS-GPS-200

Fixes since v14.6.0

  • Fix EngNav such that subframe pattern ID look-ups disallow unassigned SV ID values.
  • Fix PNBBDSD1NavDataFactory Change SOW cracking from asSignedDouble() to asUnsignedInt()
  • Fix SNAPPER Check ptr for null before calling string constructor. Running SNAPPER with lambda in cloud doesn't have the env variable $HOME by default
  • Fix GPSLNavEph fit interval computation.
  • Fix correct destruction of NavData with virtual destructor

Removed Code due to Deprecation

  • No longer build and publish packages with std C++11
