GN-8421A 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. It delivers fast, accurate positioning data in challenging locations like indoor environments and deep urban canyons.

GN-8421A is ideal for a wide range of applications where performance, time to market and ease of integration are prime considerations. It includes two SAW filters for high performance when integrated with wireless communications, and has advanced features for use in car navigation devices and fleet management.

GN-8421A is based on OPUS III technology and includes the OPUS IIIez BB IC and the Prelude III RF Receiver IC, a TCXO, two SAW filters and various matching and peripheral components in a small form factor. It is your complete GPS/AGPS solution with only an external GPS antenna and power supply required.
