GM-8461 is a miniature high-sensitivity, low-power GPS/AGPS module which integrates eRide’s hardware Measurement Platform (MP) into a single, compact and easy to integrate SMD device.
GN-8462 is a high-sensitivity, complete GPS/AGPS receiver module that combines a hardware measurement platform with eRide’s powerful navigation software integrated onto an embedded 32-bit RISC microprocessor.
