Reach comes with a ReachView web app that works on any device with a browser and does not require an internet connection. Easily configure settings, correction input and solution output. Record, manage and download RINEX logs. View status, connection state, captured event marks.
On every step ReachView helps you to quickly setup the device for work. NTRIP mount points will be automatically retrieved from the caster and displayed on the screen, radio data rate will be recalculated right after you select the required RTCM messages.
ReachView allows you to monitor your installation by providing extensive data about the environment such as current satellite signal strength, constellation visibility forecast, your location on a map.
ReachView is getting constantly improved and updated. When connected to the Internet it will automatically check if the new version is available and show you a notification. Simply tap the update button to receive new features and advancements.


With IP67 rating and rugged polycarbonate enclosure Reach RS is ready for outdoor work. The receiver weighs only 690 grams and is just 145 millimeters wide making it one of the smallest and lightest RTK units available.


Reach RS is perfectly suited for all kinds of survey work including point collection and stakeouts. With modern interface and integration to major data collection apps it brings a totally new user experience in RTK systems and the price point finally allows you to deploy as many as your team needs.
By using Reach RS as a base station and Reach module on an aerial mapping drone you can drastically improve your mapping process by reducing the amount of ground preparations. Reach helps to precisely geotag pictures eliminating the need of using GCPs.
All-weather resistance of Reach RS allows it to work outside 24/7 - all you need is to provide a constant power supply to keep it running. Together with its wireless connectivity support it is a perfect solution for object movement monitoring.
With its vast connectivity options Reach can be integrated into virtually any system. It can supply high precision coordinates in a widely supported NMEA format and through a multitude of communications channels. RS232, WiFi, Bluetooth, USB - the choice is yours.


Reach RS is packed with connectivity options. Via built-in WiFi it is able to access NTRIP corrections, stream data to the cloud and fetch software updates.

In remote areas Reach RS units can communicate via integrated LoRa radios giving you a reliable correction link on distances up to 8 kilometers.

Solution data can be accessed over Bluetooth, WiFi and RS232. Functionality is extendable even further using the USB OTG.

  • Do I need 2 Reach RS units and how do they communicate? Precise positioning is achieved by using two receivers. They could produce solution in real-time (RTK) or collect raw phase measurement data for post-processing (PPK). Only in the first case constant communication between rover and base is required, you can use radio, Wi-Fi or internet connection depending on your usage scenario.
  • Can Reach RS act both as base station and rover? Yes, it can work in base and rover modes simultaneously.
  • What are the required operating conditions? RTK positioning uses signals coming from space and Reach RS has to be placed outside with clear sky view. Highest precision is obtained in low multipath conditions and with calm ionosphere.
  • What is the maximum distance between base and rover units? For solid performance in kinematic mode we recommend separation distance (baseline) up to 10km, in static mode up to 20km. Baseline could be increased even further depending on local conditions.
  • How many rovers can I use with one base station? Corrections from the Reach RS configured as a base can be broadcasted to an unlimited number of rovers.
  • Can I use it in pair with another RTK receiver? Definitely! Thanks to use of RTCM3 and RINEX formats Reach RS is compatible with existing RTK receivers from major brands as well as with reference networks worldwide.
  • Does Reach RS work with Reach module? They work perfectly together! Reach RS can be used as base station for Reach module installed in a drone.
