SiRFstar IV SIP GPS Receiver Module based on CSR’s latest GSD4e chip with twice the sensitivity of the SiRFstar III.
The Inventek ISM420R1-C33 is a 48 channel global positioning system (GPS) receiver in a 9.5 x 10.5 x 2.4mm Surface Mount Device (SMD) GPS module with high sensitivity, high gain, and low power. The small form factor GPS receiver is designed for a broad spectrum of OEM applications and is based on the fast and deep GPS signal search capabilities of CSR SiRFstarIV™ architecture.
- The module is capable of generating and storing extended ephemeris data to an external device for much faster hot starts in weak signal environments.
- Built-in jamming detection and mitigation to permit fast and accurate navigation solutions in high noise environments.
- Ability to use an external MEMS device for wakeup when motion is detected, thus reducing power consumption for tracking devices.
- An addition 4 dB in tracking sensitivity and 5 dB navigation sensitivity over the world class SiRFstar III devices.
- < 10 mW @ 1.8 volts required to maintain fixes in Trickle Power mode for the ultimate in low power requirements.
