NXP Semiconductors has released a new family of SiGe:C low noise 
amplifiers (LNAs) designed to improve the linearity, noise figure and 
reception of GPS signals, including GloNass and Galileo, while offering 
the smallest footprint in the market. A unique capability of the BGU700x 
family of GPS LNAs is dynamic gain adaptation to improve reception of 
weak GPS signals in the presence of strong signals from mobile phone, 
Bluetooth or WLAN transmitters. This improves IP3 by 10 dB or more under 
-40 to -20 dBm jamming conditions, with the noise figure remaining below 
1 dB.

Quite how they will cope with LightSquared though?
