Description

A compact and affordable Multi-band GNSS RTK receiver with built-in IMU for precise navigation and UAV mapping without ground control points.

Centimetre Accuracy with the Reach M2

The Emlid Reach M2 needs access to corrections for centimetre accuracy. Obtained over the Internet (NTRIP) or a local Reach RS2 base station can be used.

NTRIP Corrections

NTRIP (Networked Transport of RTCM via Internet Protocol) allows a RTK GNSS receiver (client) to communicate with a base station (caster) over the internet to achieve cm level accuracy.

Base Stations

A base station is a unitset to a known latitude, longitude and height. 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.

An Emlid Reach RS2 is suitable for use as a base station. They are capable of transmitting corrections locally or over the internet. If set up locally, all recorded positions will be relative to the position of the Base Station.

Baseline

Whether using NTRIP or a RS2 sending corrections over the internet. It is important to note the baseline. The baseline is the term given to the distance between the base station and the GNSS Receiver (Reach M2). The baseline is important, because the atmospheric conditions will be different at different locations. Therefore there will be less accuracy the further the rover gets from the base.
