M20 RTK all-bands GNSS rover

RTK all-band GNSS Development Kit on M20 High Precision GNSS receiver with centimeter accuracy. Helix Antenna on SMA connector, USB-C connector and 1/4" thread mount, IP67 waterproof case. Wireless Bluetooth or Wi-Fi operation. All-band receiver delivers centimeter-level accuracy in seconds. Designed for surveying, mapping and navigation. Supported different antenna and wireless connectivity options.

With the RTK GNSS Development Kit you will have everything you need to start your surveying, mapping and navigation tasks with RTK and centimeter level accuracy. You can use your preferred Android application to connect with the kit over Bluetooth or use BY_Connect Bynav Evaluation Software to connect directly to M20 high precision GNSS module over USB-C.

Development Kit ensures the security of positioning and navigation information by using secure interfaces and advanced jamming and spoofing detection technologies. It comes with built-in support for standard RTCM corrections, supporting centimeter-level navigation from local base stations or from virtual reference stations (VRS) in a Network RTK setup.

Connectivity

Development Kit provide data in standard NMEA that is used by most GIS applications.  Direct access to the M20 GNSS module on USB-C connector allow to use BY_Connect Bynav Evaluation Software for many applications.

Base station

Development Kit needs a base station as a source of corrections for centimeter accuracy in RTK and PPK. Base might be either NTRIP/VRS service or our ELT0631 Base station. Please download and install Lefebure NTRIP client for Rover applications.

Power

Development Kit powered from external rechargeable power bank, we recommend to use our 7800mAh power bank, supplied with the Kit. Typical working time up to 20 hours, power bank can be charged from any USB C PD charger.

Antenna

Development Kit can be used with any external active GNSS all-bands antenna with SMA connector. Our ELT0170 Helix antenna included to the kit. Depending of the application, Helix antenna or Patch antenna can be used.

Environment

Development Kit designed in small IP67 waterproof round case 65 mm height, 34 mm diameter and 100g weight and can be used in harsh environment. Case have 1/4" thread mount, allowing to use any typical camera monopod or tripod. 1/4" to 5/8" thread convertor included to use with survey equipment.

Applications
