Emlid Reach RS2 and Reach RS+ – What is a GNSS receiver and how do we use it? What advantages do they offer us?

Introduction – What is GNSS Receiver?

GNSS or “Global Navigation Satellite System” is a general term used for satellite navigation systems that provide autonomous geo-spatial positioning with global coverage. These systems are composed of a constellation of satellites that provide positioning and synchronization data to the GNSS receivers. The receivers then use the data provided to determine the exact location.

The applications of these systems are found in many fields and are implemented in most devices, some common examples would be tracking devices, mapping, industrial machinery and equipment, ships, air navigation, automobiles, and the most common: smartphones.

The performance of a GNSS receiver is measured by:

  • Accuracy – the difference between the position, time, or speed measured from the actual one

  • Integrity – the ability to provide a level of confidence, a notification system or an alarm in the event of a position data anomaly

  • Continuity – the ability to operate without interruption

  • Availability – the percentage of time the signal maintains its accuracy, integrity and continuity

Therefore for a millimeter accuracy, we need a high-performance receiver, a dedicated device. One of them and the one we will present is Reach RS + from Emlid.

Emlid Reach RS+ and RS2

Reach RS + and RS2 are GNSS receivers that use RTK (Real-time kinematic) technology for greater accuracy, being the best receivers in terms of value for money on the market, being common in areas such as precision agriculture, mapping, and topography.

Can be used for:

  • Point collection

  • Point localization

  • Machine guidance

  • Base – base station

  • Rover – mobile station

Advantages RS+ and RS2

  • Easily controllable with a smartphone or tablet via Bluetooth or WI-fi

  • Prolonged use due to its battery life of up to 30 hours on the RS+ and 22 hours on the RS2

  • 8GB Storage for the RS+ and 16GB storage for the RS2 for measurements and recordings

  • IP67 Certificate for water and dust proof protection

  • Resisting to extreme conditions and temperatures from -20 °C to +65 °C

In the following articles, we will walk through step by step on how to use the RS+ and RS2 devices.
