 Venus6T reference module

Taiwan fabless AGPS firm SkyTraq Technology Inc. has released a small-footprint standalone GPS reference module using its low-power Venus6T GPS chipset.

Measuring 13mm x 16mm, the reference module consumes 50mA during signal acquisition and 28mA during continuous tracking. Low current consumption makes the device suitable for consumer GPS applications ranging from handset, personal navigation, photo geo-tagging, to security tracking that requires low power, high performance and low cost.

The Venus6T chipset consists of ROM-based Venus624LP single-chip GPS baseband and Venus120 RFIC. It requires low external component count and small footprint PCB.

Dedicated signal parameter search engine within Venus624LP is capable of performing 8 million time-frequency hypothesis testing per second; offering ultra-fast 1-second hot start and 29-second cold start under open sky. Advance track engine allows signal detection better than -158dBm, enabling continuous navigation in harsh environments such as urban canyon and under deep foliage. The Venus6T chipset consumes 65mW during signal acquisition and 40mW during continuous tracking.

Evaluation kit based on the reference module is available.
