This chapter provides an overview of the JNSGyro-2T, including its features
and physical elements. In addition, a brief description of the principals of GPS
operation is presented.
Overview
JNSGyro-2T (Figure 1-1) is a dual frequency satellite based two-antenna
system that measures true heading. It contains two 20-channel geodetic quality
dual frequency GPS/GLONASS receivers packaged in one small box that is
connected to two antennas whose base-line is fixed at the time of installation.

The JNSGyro-2T can receive and process L1 and L2 signal. The GNSS
component of JNSGyro-2T means you can access both the GPS (Global
Positioning System) satellites of the United States, and the GLONASS (Global
Navigation Satellite System) satellites of the Russian Federation, increasing the
number of satellites your board can detect, thus improving the accuracy of your
measuring points, increasing productivity, and reducing cost.
