Description:
GM-A703 is an easy to use, ultra-high performance, low power GPS receiver module with patch antenna for AVL /marine applications. It supports multiple satellite positioning systems – GPS, QZSS, GLONASS, and SBAS. The SMT mountable design allows mass production with automatic assembly. With GM-A703, the RF tuning efforts and also development time is reduced to the minimum. An optional hardware controlled power switch was built-in. It allows power cycling by the PWR_CTRL pin. Our experienced design fully exhibits the excellent performance of SiRFstarV chip. It works in GPS signal difficult environment, provides fast acquisitions and excellent tracking performance.Specifications
