Overview

The UD-731N (GPS receiver)is a compact all-in-one GPS receiver that continuously tracks all satellites in view and provides accurate satellite positioning data. The built-in NAND Flash memory supports for data storage. The navigation software and map can be installed to be a completed navigation dongle.   It provides fast satellite signal acquisition and short start-up time. Reacquisition sensitivity of -160dBm and tracking sensitivity of -160dBm offer good performance even under difficult environments.  

The UD-731N (GPS receiver) is optimized for applications requiring good performance and low cost; it is suitable for a wide range of handhelds, asset tracking, Notebook, PDA-centric personal navigation system, and vehicle navigation products.   2G/4GB FLASH: Travel along with FLASH and Navigation function
