sat nav

A satellite navigation or satnav system is a system that uses satellites to provide autonomous geo-spatial positioning. It allows satellite navigation devices to determine their location (longitude, latitude, and altitude/elevation) to high precision (within a few centimetres to metres) using time signals transmitted along a line of sight by radio from satellites. The system can be used for providing position, navigation or for tracking the position of something fitted with a receiver (satellite tracking). The signals also allow the electronic receiver to calculate the current local time to a high precision, which allows time synchronisation. These uses are collectively known as Positioning, Navigation and Timing (PNT). Satnav systems operate independently of any telephonic or internet reception, though these technologies can enhance the usefulness of the positioning information generated.
A satellite navigation system with global coverage may be termed a global navigation satellite system (GNSS). As of September 2020, the United States' Global Positioning System (GPS), Russia's Global Navigation Satellite System (GLONASS), China's BeiDou Navigation Satellite System, and the European Union's Galileo are fully operational GNSSs. Japan's Quasi-Zenith Satellite System (QZSS) is a (US) GPS satellite-based augmentation system to enhance the accuracy of GPS, with satellite navigation independent of GPS scheduled for 2023. The Indian Regional Navigation Satellite System (IRNSS) plans to expand to a global version in the long term.Global coverage for each system is generally achieved by a satellite constellation of 18–30 medium Earth orbit (MEO) satellites spread between several orbital planes. The actual systems vary, but all use orbital inclinations of >50° and orbital periods of roughly twelve hours (at an altitude of about 20,000 kilometres or 12,000 miles).

    Question: Trophy Sat Nav - should it do online searches?

    I have been used to the old MG4 Trophy for the past 2 years, where I can enter a location/company name into the sat nav search, and it would come back with the address and correctly route there. The MGS5 does not seem to do this - instead offering random roads in Europe that may match the...

    Sat Nav Direction.

    I have a MG3 hybrid 2024 U.K. The sat nav shows the compass point I am travelling in. i.e. if I am going south it shows me going south. Can it be changed to show starting at the bottom of page and going up? Or starting at left and my destination is on the right?

    Sat Nav location issues on starting up.

    I'm sure I've read of someone else having this issue, but my MG3 Hybrid+ Trophy has an issue with the Sat Nav in that when I select it, if I'm stationary, it will often show a previous location and not update to where I actually am. I've looked in the GPS details and it even does this when it is...

    Time limited Sat Nav etc?

    I was checking all the settings on my new ZS & I noticed on the Sat Nav that the connectivity expires in 5 years for I assume Sat Nav, Weather & Amazon Music. I presume for a small exhorbitant fee MG would extend it. Has anyone done that? Seem it isn't needed with android auto.
