Overview
SR-91 is an easy to use, ultra-high performance, low power GPS engine board with active antenna options for handheld/AVL applications. The built-in SiRFstarIII chip and experienced design provide fast acquisitions and excellent tracking performance. The SMT mountable design allows for automatic assembly mass production.
SR-91 is especially useful for handheld/small size applications. It supports both passive and active antenna. To reduce the RF tuning efforts and also development time, SR-91 supports active antenna with an I-PEX connector. To meet this demand and simplify active antenna choices, NaviSys also offers companion options.
