For the three hundred seventieth edition of the GeoGearHeads ChrisOfTheNorthWest and DarrylW4 talk through several articles. The first was the "One map. Endless inspiration." Then the news about Munzee 4 dropped. Also noted was the "2017 Public Interface Control Working Group and Forum for the NAVSTAR GPS Public Documents" post about receiver week roll-over behavior. Last up – "First GPS III satellite successfully launched." The live video session from this Hangout On Air can be found on YouTube.
