GT-720FGM
54 Channels GPS Receiver, PS2 GPS, RS232 GPS
GENERAL DESCRIPTION
The GT-720FGM is a compact all-in-one GPS receiver that continuously tracks all satellites in view and provides accurate satellite positioning data.
Incorporating the high GPS technology, GT-720FGM with acquiring 54 channels ability improving cold-start fast positioning. It can track 54 channels down to 159 dbm and offers extremely accuracy even under attenuated situations such as high buildings in urban areas, dense foliage and even indoor. Satellite-based augmentation systems, such as WAAS and EGNOS, are supported to yield improved accuracy.
The GT-720FGM is optimized for applications requiring highperformance and low cost; it is suitable for a wide range of handhelds, asset tracking, Notebook, PDA-centric personal navigation system, and vehicle navigation products.
