- Best-in-class acquisition and tracking sensitivity, TTFF and accuracy: 157 dBm acquisition / 159 dBm tracking sensitivity in A-GPS and autonomous hot start modes
- Optimized for both cellular handset and portable consumer device integration
- DynaTrak advanced tracking and multipath algorithms for robust low dropout tracking in indoor, very low signal and rapid signal transition environments
- Hosted architecture optimized for cost and performance
- Supports GSM, WCDMA and CDMA control plane A-GPS assistance data standards
- Supports SUPL user plane A-GPS assistance data
- Exceeds 3GPP and TIA performance requirements
- Ultra-low power consumption: 30mW in 1Hz tracking mode
- Supports all common GPS and cellular handset reference frequencies (10 – 50MHz)
- Very low external component count and PCB size
- Supports ultra-low cost PCB dipole antennas
- UART and SPI host interfaces
- Operating temperature range -40C/+85C

Its ashame that this office furniture site above which is offering inexpensive furniture is posting a comment on a site that is COMPLETELY unrelated to the subject! Ironically I do own a furniture company that provides affordable furniture however I did come here with the intention of reading about the Navigation stuff!
