The NTL Geo is based on the high-precision OEM GNSS receiver modules of NTLXXX family. The main feature of the device is the possibility to explore multi-constellations GNSS signals. The NTL Geo allows to simultaneously tracks GPS L1/L2/L5, GLONASS L1/L2, Galileo E1/E5a/E5b, BeiDou B1/B2, NavIC L5/S-band and SBAS L1 signals. Customers can use it for develop own proprietary or use third-party software to implement post processing to create an effective solution for each specific case using on-board Computer-on-Module Platform with Windows/Android/Linux operation system. Also it is possible to use different types of wireless interfaces due to mini-PCI Express connection availability. The list of optional plug-in wireless and wired interfaces is mentioned below.

Two navigation modules allow to connect up to four antennas for using the NTL Geo with the wide range of GNSS antennas equipment. The navigation modules are managed by computer module with SMARC architecture via UART interfaces. Computer module contains all required peripheries for external communications; USB, Ethernet, RS232, HDMI and controlled by OS. The keyboard, mouse and monitor can be connected to the GNSS receiver unit for the local management.
The Wi-Fi module is designed to connect to a local network and organize a channel for receiving differential corrections (RTK, PPP).
This device is intended for:
- high-precision positioning (RTK, PPP);
- autonomous positioning;
- generating GNSS measurements (code and phase pseudorange, Doppler measurements, estimation of signal-to-noise ratio).
- the development, debugging and testing of various applications oriented to GNSS signal processing.
