u-blox has added a GPS smart antenna module (SAM) to its product range. This complete receiver with integrated antenna makes fast and easy integration possible, and speeds up customers' design cycles, according to the company.
A complete GPS receiver with an integrated ceramic patch antenna, SAM is based on the u-blox macro-component TIM, and provides superior GPS performance in a very small-sized package (31,5 x 47 x 9,5 mm; 23 g).
Operating at a 3,3 V nominal operating voltage, the module consumes less than 0,5 W at a 1 Hz position update rate. Advanced low power modes allow for a considerable reduction of power consumption in applications where power consumption is of primary concern. A serial interface and power are all that is required for interfacing with the SAM GPS smart antenna. A firmware upgrade can add datalogging functionality to the SAM. This firmware uses the internal Flash memory to store up to 100 000 positions. Position, velocity and time are stored according to user-defined event criteria such as time or distance. This upgrade is free of cost.
Position information is key to many portable applications, such as mobile payment terminals and portable tracking devices. In such applications the GPS receiver and the GPS antenna are integrated into the device. The integration of a passive antenna and a GPS receiver is not a straightforward exercise and adds significant risk to a project. With the SAM smart antenna module u-blox says it offers a ready to go solution and supports reduced time to market.
