Centimeter Accuracy with the Reach RS+

For centimeter accuracy the Emlid Reach RS+ GNSS RTK Rover will need to have access to GNSS corrections. There are two ways to acheive this, either by sourcing NTRIP corrections over the internet or by pairing with another unit in RTK mode.

Base Stations
A Base Station is usually set to a known latitude, longitude and height when it is placed, this is referred to as a ‘known’ point. This base will keep monitoring the satellites above and will calculate position corrections and send them to the Rover.

Emlid Reach RS+ can be used as a Base Station, it can either be set up on a ‘known’ point at a static location and ‘transmit’ corrections over the Internet. It can also be set up locally, if this is the case all results will be cm accurate relative to the base station position.

When it comes to using NTRIP or an Emlid Unit transmitting corrections over the internet, it is important to note the ‘baseline’. The baseline is the distance between the GNSS Client and the Base Station in the case of the RS+ the maximum for this is 10Km. The reason for this is further the GNSS RTK Rover from the base station the less accuracy it will have. This is due to different atmospheric conditions at different locations.
