简 介
The CM8 is a POT (Patch On Top) GPS second generation module. It has more compact size than
the first generation. This POT GPS receiver providing a solution that high position and speed
accuracy performances as well as high sensitivity and tracking capabilities in urban conditions.
The CM8 can acquire and track satellites down to signal levels as low as –195dBw(and can
autonomously acquire satellites down to signal levels as low as –178dBw), while still maintaining
TTFF performance of under 1 seconds outdoors.The CM8 achieves this
level of performance by using a high performance baseband processor. This level of performance
allows the CM8 to obtain rapid positional fixes in extremely weak GPS signal areas such as under
dense foliage,dense urban canyons and even inside buildings. The CM8 is an exceptionally small
surface mount package (16mmx16mmx6.7mm) with a highly integrated architecture that requires
minimal external components, allowing easy integration into host systems.
