branches/rinex3_dev), which includes unit and functional test code for many of the new classes. We have created a PDF overview presentation of RINEX 3 development giving an overview of the new features and plans. This development will culminate in a release of GPSTk 2.0. We have also set up a new Wiki discussion forum (see sidebar menu at left) where new topics may be created. Feel free to use this forum to ask questions, post comments or suggestions, or stimulate discussion of relevant issues. Brainstorming normally starts here in Development, and when ideas are refined enough to be implemented, then construction begins.
