About GPS satellites
The satellites are controlled by the United States Department of Defense and orbit at an altitude of 20,000 km.
Originally, these satellites were designed for military purposes, but now some of the information they send is for consumer
use and is used in a variety of devices such as car navigation systems and smart phones.
Supports the Quasi-Zenith Satellite System
This product supports the first Quasi-Zenith Satellite System (QZSS).
The QZSS is a system of satellites that passes directly over Japan and sends positioning signals that are very similar to current
GPS signals. This allows signals to be sent to wider areas of Japan that were previously trouble spots, such as mountainous
regions, or areas with a high density of skyscrapers.
Coordinated Universal Time (UTC) and time zones
UTC is a universal, standardized time set by international accord. This is used as the official time when time is recorded
around the world.
Around the world, countries and regions use common standard times based on Coordinated universal time (UTC).
Standard times are determined by specific countries and regions, and a region that uses the same standard time is
called a time zone.
* The time zone for each region may change depending on the circumstances of the country or region.
Daylight Saving Time (DST)
Daylight Saving Time (DST) is a system that advances standard time by one hour (or another specific time) during
long periods of daylight, normally during summer. Also known as summer time.
This system is used in approximately 80 countries around the world, mainly in Europe and the United States, in
countries at a high latitude and long daylight hours in the summer.
* The way DST is implemented may change depending on the circumstances of the country or region. Also, the period during which
this is applied varies by country/region.
