Adafruit Ultimate GPS Breakout - 66 channel,10 Hz updates - v3

This is the ultimate GPS module from Adafruit Industries.

The breakout is built around the MTK3339 chipset, a no-nonsense, high-quality GPS module that can track up to 22 satellites on 66 channels, has an excellent high-sensitivity receiver (-165 dB tracking!), and a built in antenna. It can do up to 10 location updates a second for high speed, high sensitivity logging or tracking. Power usage is incredibly low, only 20 mA during navigation.

It's got everything you want and more:

• - -165 dBm sensitivity, 10 Hz updates, 66 channels
• - 5V friendly design and only 20mA current draw
• - Breadboard friendly + two mounting holes
• - RTC battery-compatible
• - Built-in datalogging
• - PPS output on fix
• - >25Km altitude
• - Internal patch antenna + u.FL connector for external active antenna
• - Fix status LED

Best of all, we added all the extra goodies you could ever want: a ultra-low dropout 3.3V regulator so you can power it with 3.3-5VDC in, 5V level safe inputs, ENABLE pin so you can turn off the module using any microcontroller pin or switch, a footprint for optional CR1220 coin cell to keep the RTC running and allow warm starts and a tiny bright red LED. The LED blinks at about 1Hz while it's searching for satellites and blinks once every 15 seconds when a fix is found to conserve power. If you want to have an LED on all the time, we also provide the FIX signal out on a pin so you can put an external LED on.

To improve GPS reception, you would need to separately get both an External GPS Antenna as well as a SMA to uFL Adapter Cable.
