The A2235-H GPS module enables fast acquisition and tracking with SiRFstar IV technology. This small form-factor module addresses the demand for low power consumption with SiRFaware technology. The removal of jammers and high sensitivity during acquisition allows for use in many different environments and under tough operating conditions.
The A2235-H GPS module enables fast acquisition and tracking with SiRFstar IV technology. This small form-factor module addresses the demand for low power consumption with SiRFaware technology. The removal of jammers and high sensitivity during acquisition allows for use in many different environments and under tough operating conditions.
Small footprintThe power pins, ground pins, and dedicated pins are at the same pin location across device densities so it can adapt to your actual configuration. |
 |
Ultra Low power consumptionSiRFaware’s advanced low power management modes, high level of integration and multiple communication ports in a small form-factor makes the A2235-H suitable for a broad spectrum of GPS applications where performance, cost and time to market are prime considerations (only 29 mA average tracking). |
 |
Anti-jamming detectionOur receivers offer an anti jamming feature: they constantly scan the signals in the area and blank out the non-satellite ones. You are then safe from jammers and others interferences. |
