Overview
Javad Navigation System's Maxor is a dual-frequency, GNSS receiver
built to be the most advanced and compact receiver for the navigation market
(Figure 1-1).
Figure 1-1. Maxor Receiver
The Maxor can receive and process both L1 and L2 signals, improving the
accuracy of your measuring points and positions. The GNSS component of
Maxor receivers 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 receiver can detect, thus improving the accuracy of your
measuring points, increasing productivity, and reducing cost.
The dual-frequency and GNSS features of the Maxor combine to provide the
only real time kinematic (RTK) system accurate for short and long baselines.
Several other features, including multipath mitigation and common tracking,
provide under-canopy and low signal strength reception. The Maxor receiver
provides the functionality, accuracy, availability, and integrity needed for fast
and easy data collection.
