POT GPS receiver

The FGM-RLP is a POT (Patch on Top) GPS receiver which is special designed for ultra low power consumption purpose environment. It provides a perfect solution to high position and speed accuracy performances as well as high sensitivity and tracking capabilities in urban conditions. The chipsets inside the GM-RLP are designed by MediaTek Inc., which is the world's leading digital media solution provider and largest fab-less IC company in Taiwan.

The FGM-RLP can support up to 66 channels and simultaneous tracks up to 22 satellites. This GPS solution enables small form factor devices. They deliver major advancements in GPS performances, accuracy, integration, computing power and flexibility. This product can communicates with other electronic products or instruments via serial communication through RS-232 interface and TTL level. It had also build-in a LED indicator for the positioning state (3D-fix). The FGM-RLP is designed to simplify the embedded system integration process and also easy to install in handheld goods.
