A5100 GNSS Receiver Lantronix A5100 GNSS Receiver is a compact, high-sensitivity, concurrent GNSS module that integrates CSR's latest SiRFstarV technology into a single, compact and easy to integrate SMT device. A jammer removal algorithm not only facilitates integration in today's ever more complex communication devices but guarantees performance even in hostile situations. Advanced low power management modes, high level of integration and multiple communication ports in a small form factor make the A5100-A suitable for a broad spectrum of GNSS applications where performance, cost and time to market are prime considerations.
