Receiver GM23

GENERAL INFORMATION 

The GM23 is an integrated solution of receiver and GPS L1 antenna, SIRF IV architecture-based. This positioning system meets the minimum requirements for use in automobiles, maps, security, agriculture, and much more.

It communicates with other devices through a serial RS232 port.

With low power consumption, the GM23 can receive up to 48 satellites at the same time, and regain signal within less than 100 ms.

Position data are updated every 1 second. It also has a WAAS signal reception channel, which allows for greater accuracy in places where this  signal is available.

FEATURES 

• Positioning down to 1 Hz
• L1 GPS Band  
• Positioning accuracy 1-5 meters. 
• Compact design ideal for applications with a minimum of space. 
• Battery charges itself during normal operation.
• The LED provides users with visible positioning state. 
• Built-in WAAS demodulator. 
• Waterproof design.
