EMLID REACH RS+ and RS2 - What is a GNSS receiver and how do we use it? What are the benefits that they offer?

Introduction - What is a GNSS receiver?

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

Applications of these systems are found in many areas and are implemented in most devices, some common examples being tracking devices, mapping, industrial machinery and equipment, maritime vessels, air navigation, automobiles and the most widespread: smartphones.

The performance of a GNSS receiver is measured by:

  • Accuracy - the difference between the position, time or speed that it was measured and the actual one

  • Integrity - the ability to provide a level of trust in the data, a notification or alarm system in the event of an anomaly of the positioning data

  • Continuity - ability to operate without interruption

  • Disponibility - the percentage of time the signal maintains its accuracy, integrity and continuity

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

Reach Emlid 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 the market for quality-price ratio, being common in areas such as precision agriculture, mapping and topography.

They can be used for:

  • Collecting points

  • Locating points

  • Guide the machines

  • Base - Fixed station

  • Rover - Mobile station

RS + and RS2 benefits:

  • Easily controlled with a smartphone or tablet via Wi-Fi or Bluetooth

  • Long life due to battery life up to 30 hours (RS+) and 22 hours (RS2)

  • It has 8GB of storage space (RS+) respectively 16GB (RS2) for measurements and recordings

  • IP 67 certification for water and dust resistance

  • Resistance to extreme conditions being usable at temperatures from -20°C to +65°C

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