I hope so :-) TI themselves say "High performance: The GPS5300 NaviLink 4.0 solution enables a rapid time to first fix (TTFF) from weak satellite signals, exceeding the GPS requirements for 3GPP and 3GPP2 operation."

Anyone has the 3GPP specs and knows if there is a TTFF requirement mentioned inside?

I only found this tidbit from 2000, related to A-GPS as supported by the chipset: "[Without the assistance information] the Time-to-First-Fix (TTFF) could be in the range of 20-45 seconds."

That would be acceptable Currently, it is too slow for me.
