I've been testing a new cycling computer, a Bryton Rider 450<\/b>. I was shocked<\/span> to find out some information\nabout its satellite-positioning features that isn't covered in the manual, so I'm sharing that info here.<\/p>\n\n

As a bit of background, folks often use the “<\/span>GPS<\/b>”<\/span> as a generic<\/span> term for “<\/span>satellite positioning system”<\/span>,\nbut in reality, GPS<\/b> is the specific satellite positioning system built and deployed (and offered as a gift<\/span> to the world) by\nthe United States of America. It used to<\/span> be the only one, but now there are several. Russia has its\nunrelated GLONASS<\/b> system, the European Union has its Galileo<\/b> system. These all provide global coverage. Regional\nsystems include China's Beidou<\/b> system (which will eventually be global), and India's IRNSS<\/b> system.<\/p>\n\n

In addition, Japan has a small four-satellite augmentation to the United States's GPS system called “<\/span>QZSS”<\/span> (\u307f\u3061\u3073\u304d in Japanese).<\/p>\n\n

The Bryton Rider 450 is advertised to work with all of these except IRNSS. This in theory would allow my use\nhere in Japan to benefit from the three truly-global systems (GPS, GLONASS, and Galileo), and two regional systems (Beidou and QZSS),\nso hopefully it would be more accurate than other units I've used.<\/p>\n\n

(In years past, I've posted a few articles about GPS accuracy, including\nhere<\/a> and\nhere<\/a>.)<\/p>\n\n\n

So it was with dismay that I opened up the configuration menu on the unit to find only these options available:<\/p>\n\n
