As @u89djt mentioned, a lot of info was just revealed about the new sensors in a presentation and Q&A with Bob Mimlitch, Levi Pope, Dan Mantz, and Jim Crane at the in-person VEXU/VEXAI competition and can be watched on the stream (VEX U In-Person Championship hosted by the REC Foundation - YouTube). It starts right at about 3 hours into the stream. The Q&A in particular had several questions specifically about VRC Skills use of the GPS sensor and the field positioning strips.
Bob, Dan and Jim all have verified that it will be legal for use in VRC skills ONLY this coming season, and that the upcoming game manual update will include information that the strips will be required on VRC skills fields. The question about how to handle fields that are used for both skills and competition matches was brought up, and varying suggestions, such as having strips that can be installed as needed vs. asking teams to unplug their GPS sensor during matches were both suggested. The strips will be single 12’ roles made of banner-like material that can be velcroed into the field wall perimeters. The opaque panels will not be required in order to use the GPS sensors and strips.
