2.   GPS accuracy – What is good, settings and how have things changed over the years?



3 x Satellites show position 2d, 4 x Satellites 3d elevation



What is Multi GNSS (Global Navigation Satellite system)

Device picks up more than one set of Satellite Constellations

Main ones we use in devices such as Garmin, TwoNav, Coros



GPS – USA 1978 started Military - Global use 1994

31 Satellites

Glonass – Russian development 1976 – operational early 80’s

24 Satellites operational

Galileo – EU – 2016 started

26 Operational

Beidou – China – Started 2012

56 Operational

Twonav does not use duel frequency but multi-band uses 3 x satellite constellations at once, we have been using GPS, Galileo & Beidou and seeing under 10 feet and have seen down to 4 – 5 feet

GPSMap65,67 dual frequency have seen down to 6 feet

Generally we find other handhelds picking up either GPS & Glonass or GPS & Galileo around 10 - 12 feet

Garmin Watches do not show an accuracy screen

Coros has a Satellite screen where you can see how many are in view and how many are strongly locked on



What is Dual Frequency / Multi Band

Use Coros Article



GPS – 18 satellite transmit at L1 & L5

Glonass – older L1 & L2 no L5



Galileo – all E1 & E5

Beidou – all B1 & B2



Devices we sell with dual frequency Epix gen 2, Fenix 7 sapphire solar & pro models
