On April the 6th, 2019, GPS will have a sort of Y2K-type rollover thing happening. The 10-bit weekcode will roll over from 1023 back to 0. Most recent GPS modules will have this accounted for, others require a firmware upgrade to deal with this fact. At the same time, this field in the GPS data will also be increased in bitcount. Just putting this here to raise awareness of this, hoping the GPS modules in the Pyra Mobile edition have this accounted for. Together with any accompanying software.
