L70, a SMD type module, brings the high performance of the MTK positioning engine to the industrial applications with compact profile, ultra low power consumption and fast positioning capability.
Additional feature of embedded logger function called LOCUS allows L70 to log position information to internal flash memory at default intervals of 15 seconds and provide typically more than 16 hours log capacity without adding cost.
With its tiny design, high precision and sensitivity, L70 is perfectly suitable for a broad range of M2M applications such as portable device, automotive, personal tracking, security and industrial PDA.
