OPUS ONE Chipset
ePR1015B
eOP1100B
OPUS ONE is a miniature high-sensitivity, low-power GPS/AGPS receiver that
combines a hardware measurement platform (MP) with powerful Navigation Software designed to run on a host microprocessor. It delivers fast, accurate positioning data in challenging locations like indoor environments and deep urban canyons.
This MP chipset includes the OPUS ONE Baseband IC and the Prelude ONE RF Receiver IC. The Navigation Software leverages the resources of the host CPU, resulting in a GPS solution that offers less redundancy, lower power consumption, and unparalleled cost savings.
The OPUS ONE baseband employs novel decoding algorithms, effectively achieving 44,000 correlators. Taking measurement data through a single input from the Prelude One, it supplies satellite measurement data to the host processor via a simple UART interface.
The Prelude One combines an LNA with an image-reject mixer/RF-AMP, a bandpass filter, an AGC, and a fully-integrated VCO/PLL.
