OPUS ONE compactRide
eMD1000K
compactRide is a compact high-sensitivity, low-power GPS/AGPS module that integrates eRide’s hardware measurement platform (MP) into a single, compact and easy to integrate SMD device. Combined with eRide’s powerful Navigation Software running on a host microprocessor, the module offers a complete high performance GPS receiver.
compactRide is based on Opus One technology and includes the Prelude One RF Receiver IC, OPUS One Baseband IC, a saw filter, the TCXO and various matching and peripheral components in a small form factor suitable for a broad spectrum of GPS applications where performance, cost and time to market are prime considerations.
