Taoglas® EDGE™ Locate Smart Antenna with High Precision GNSS and RTK

Taoglas EDGE Locate

Next-generation Smart Antenna for High Precision GNSS Positioning

The Taoglas EDGE Locate solution is an ultra-low-power IoT hardware platform providing cm,-level positioning to high volume navigation and autonomous applications in an off-the-shelf, compact form factor. EDGE Locate combines a GNSS L1/L2/E5 antenna, RF electronics and receiver technology that delivers reliable, high accuracy positioning.

With EDGE Locate, enterprises can future-proof their IoT deployments and optimize location-based performance with multi-band GNSS technology and optional RTK capabilities, providing cm-level accuracy when using RTK.

Enterprises can quickly and effectively build IoT devices with cm-level positioning technology, without having to invest in costly and lengthy RF design, integration, and testing processes. The EDGE Locate enables location-specific, mission-critical services such as emergency response, smart infrastructure, precision agriculture, micro-mobility, drone and robot delivery, and other semi-autonomous applications where precise location provides critical value to the IoT application.

What is RTK?

Real-Time Kinematic or RTK is a complex satellite navigation correctional technique that enhances the precision of position data from satellite-based positioning systems such as GPS, GLONASS, Galileo, and BeiDou. When used in conjunction with a high-performing antenna, the system allows for cm-level positional accuracy compared to standard GNSS systems. The success of mission-critical services such as emergency response, smart infrastructure, precision agriculture, and reliable e-mobility services is built on high precision services.


Taoglas EDGE Assure – Your private cloud-based correctional service. We can install fixed point RTK bases and antenna for cm-level accuracy down to 1 cm. This allows you to optimize performance according to your application’s specific needs.

  • RTK Bases provide fixed reference points
  • Taoglas correction server gathers data
  • Taoglas NTRIP caster provides rovers with correction updates
  • EDGE Locate™ rovers connect over TCP/IP to caster
  • Multiple bases provide data over a large geographic area
  • Utilizes SNIP server


NTRIP uses TCP/IP protocol to send RTCM messages. There is no requirement for you to build a private network infrastructure. Taoglas can also consult and install the RTK network for you wherever you are. NTRIP is the most commonly used method to distribute correction data and enables cm-level accuracy.
