1. Functional description 1.1 Overview The GT-U7 module series is a family of stand-alone GPS receivers featuring the high performance u-blox 6 positioning engine. These flexible and cost effective receivers offer numerous connectivity options in a miniature 16 x 12.2 x 2.4 mm package. Their compact architecture and power and memory options make GT-U7 modules ideal for battery operated mobile devices with very strict cost and space constraints.

1.3 Block diagram 1.4 Assisted GPS (A-GPS) Supply of aiding information like ephemeris, almanac, rough last position and time and satellite status and an optional time synchronization signal will reduce time to first fix significantly and improve the acquisition sensitivity. All GT-U7 modules support the u-blox AssistNow Online and AssistNow Offline A-GPS services11 and are OMA SUPL compliant. 1.

1.6 Protocols and interfaces Protocol Type NMEA Input/output, ASCII, 0183, 2.3 (compatible to 3.0) UBX Input/output, binary, u-blox proprietary RTCM Input, 2.3 1.6.1 UART GT-U7 modules include one configurable UART interface for serial communication (for information about configuration see section 1.15). 1.6.2 USB GT-U7 modules provide a USB version 2.0 FS (Full Speed, 12Mbit/s) interface as an alternative to the UART. The pull-up resistor on USB_DP is integrated to signal a full-speed device to the host.

1.8 Power Management u-blox receivers support different power modes. These modes represent strategies of how to control the acquisition and tracking engines in order to achieve either the best possible performance or good performance with reduced power consumption. 1.9 Maximum Performance Mode During a Cold start, a receiver in Maximum Performance Mode continuously deploys the acquisition engine to search for all satellites.
